A bowel management system includes a waste collection catheter having at least two distinct sections. The first section is patient proximal when disposed in the patient's rectum and has durometer hardness in the range of about 50A to about 90A. The second catheter section is connected to the first section and has durometer hardness in the range of about 5A to about 49A. A selectively collapsible, substantially spherical retention balloon is attached coaxially and exterior of the first catheter section such that the proximal-most end of the retention balloon is coincident to the proximal-most end of the first section of the waste collection catheter, the substantially spherical retention balloon having an inflated size so as to be sufficiently large enough to retain the patient proximal end of the catheter in the patient's rectum without being so large as to trigger a defecatory response in the patient.

1. A bowel management system for use in a patient comprising: a waste collection catheter including: afirst section which is patient proximal and which is disposed in the patient's rectum in normal use position, having a first end and a second end, and a durometer hardness in the range of about 50 A
1. A bowel management system for use in a patient comprising: a waste collection catheter including: afirst section which is patient proximal and which is disposed in the patient's rectum in normal use position, having a first end and a second end, and a durometer hardness in the range of about 50 A to about 90 A, so that the catheter patient proximal section is stiff enough to automatically maintain an open position for free flow of bowel waste when in normal use position with a retention balloon inflated, yet is soft and pliable enough to permit folding longitudinally for ease of insertion into the rectum of a patient; a second section having a first end connected to the second end of the patient proximal section, and a second end, and a durometer hardness in the range of about 5 A to about 49 A, so that the second section can be positioned and retained in the anal canal of the patient for extended periods without distending the sphincters or causing discomfort; and a selectively collapsible retention balloon attached coaxially and exterior of the patient proximal first catheter section such that the proximal-most end of the retention balloon is coincident to the proximal-most first end of the patient proximal first section of the waste collection catheter, the retention balloon having an inflated size so as to be sufficiently large enough to retain the patient proximal end of the catheter in the patient's rectum without being so large as to trigger a defecatory response in the patient. 2. The system of claim 1, and further comprising a lumened member which is substantially smaller in diameter than the waste collection catheter and which has a first end and a second end, the first end of the lumened member being connected to the patient proximal first section of the waste collection catheter and being in fluid communication with the selectively collapsible retention balloon, and wherein the second end of the lumened member is connectable to a port for introduction or removal of fluid from the retention balloon, for selective inflation and deflation of the retention balloon as necessary for insertion, retention or removal of the rectal catheter patient proximal segment to or from the patient's rectum. 3. The system of claim 2, wherein the lumened member has at least two independent lumens, each of the lumens being connectable at the second end of the lumened member to a port for introduction or removal of fluid from the system, one of the two lumens being in fluid communication with the first end of the patient proximal segment of the waste collection catheter, to thereby permit introduction of treatment substances to the patient's rectum. 4. The system of claim 1, wherein the retention balloon has an inflated length-to-diameter ratio in the range of about 0.75 to about 0.61, with a volume of about 44 cc to about 69 cc. 5. The system of claim 1, and further comprising an intralumenal balloon mounted to an interior of the patient proximal first segment of the waste collection catheter. 6. The system of claim 5, wherein the intralumenal balloon is in fluid communication with a lumen of the lumened member to thereby permit selective inflation and deflation of the intralumenal balloon and to function as an anti-reflux device. 7. The system of claim 5, and further comprising an intralumenal balloon mounted to the patient proximal end of the waste collection catheter, wherein the lumened member has a first lumen, a second lumen and a third lumen, the first lumen being in fluid communication with the selectively collapsible retention balloon to thereby permit selective inflation and collapse the retention balloon as necessary for insertion, retention or removal of the rectal catheter patient proximal first segment to or from the patient's rectum, the second lumen being in fluid communication with the inside of the patient proximal first segment of the waste collection catheter, to thereby permit introduction of substances to the patient's rectum, and the third lumen being in fluid communication with the intralumenal balloon. 8. The system of claim 1, and further comprising a third section of the waste collection catheter, which is positioned patient distal in normal use. 9. The system of claim 8, wherein the third section of the waste collection catheter is coated internally with a substance to facilitate flow-through of waste matter from the patient. 10. The system of claim 8, wherein the patient distal third section of the waste collection catheter is coated externally with a substance to facilitate “milking” of the waste collection catheter by a caretaker for the patient. 11. The system of claim 8, and further comprising a selectively openable and closeable access port in the patient distal third segment of the waste collection catheter to thereby permit access to the internal catheter for sampling and insertion of medication and fluids. 12. The system of claim 1, and further comprising at least one flexible strip connected adjacent to the second end of the second section of the waste collection catheter, to thereby provide optional means by which to releasably attach the waste collection catheter to the non-ambulatory patient to stabilize and secure the system in use position. 13. The system of claim 1, and further comprising a face plate of soft, pliable material, the faceplate being disposed adjacent to the second end of the second section of the waste collection catheter to thereby provide stability to the system in use position. 14. The system of claim 8, and further comprising a closure member connectable to the second end of the patient distal third segment of the waste collection catheter. 15. The system of claim 8, and further comprising a sleeve disposed about the third catheter section. 16. The system of claim 15, and further comprising a connector assembly in communication with a distal end of the third catheter section, wherein the connector assembly is received and retained by the sleeve. 17. The system of claim 16, wherein a proximal portion of the connector assembly fits in the distal end of the third catheter section. 18. The system of claim 17, wherein the sleeve is a shrinkable band that secures the distal end of the third catheter section about the proximal portion of the connector assembly. 19. The system of claim 8, and further comprising a connector assembly in communication with a distal end of the third catheter section, wherein a proximal end of the connector assembly fits in a distal end of the third catheter section. 20. A bowel management system for use in a patient comprising a waste collection catheter including: a first section which is patient proximal and which is disposed in the patient's rectum in normal use position, having a first end and a second end, and a durometer hardness in the range of about 50 A to about 90 A, so that the catheter patient proximal section is stiff enough to automatically maintain an open position for free flow of bowel waste when in normal use position with a retention balloon inflated, yet is soft and pliable enough to permit folding longitudinally for ease of insertion into the rectum of the patient;a second section having a first end connected to the second end of the patient proximal section, and a second end, and a durometer hardness in the range of about 5 A to about 49 A, so that the second section can be positioned and retained in the anal canal of the patient for extended periods without distending the sphincters or causing discomfort; anda selectively collapsible retention balloon attached coaxially and exterior of the patient proximal first catheter section such that the proximal-most end of the retention balloon is coincident to the proximal-most first end of the patient proximal first section of the waste collection catheter, the retention balloon having an inflated size so as to be sufficiently large enough to retain the patient proximal end of the catheter in the patient's rectum without being so large as to trigger a defecatory response in the patient, and further comprising a lumened member which is substantially smaller in diameter than the waste collection catheter and which has a first end and a second end, the first end of the lumened member being connected to the patient proximal first section of the waste collection catheter and being in fluid communication with the selectively collapsible retention balloon, and wherein the second end of the lumened member is connectable to a port for introduction or removal of fluid from the retention balloon, for selective inflation and deflation of the retention balloon as necessary for insertion, retention or removal of the rectal catheter patient proximal segment to or from the patient's rectum.
