A proximal housing for a full-thickness resection device (FTRD) is provided with a plurality of chambers through which fasteners are introduced into a portion of tissue to be resected. The proximal housing has a noncircular cut-out opposite the plurality of chambers to receive a noncircular endoscope. The proximal housing also is provided with a resection cavity into which the tissue to be resected is to be received. In addition, shaft openings are provided through which mounting shafts may be inserted. A noncircular endoscope is also disclosed for insertion into the cut-out whereby the endoscope has passages to house the functions of remote viewing, illumination, insufflation and irrigation.
1. A system for endolumenally resecting a full-thickness portion of an organ comprising:a flexible endoscope having a substantially non-circular cross-section, the endoscope including a plurality of chambers extending therein;a resection housing including a stapling mechanism and an anvil member mov
1. A system for endolumenally resecting a full-thickness portion of an organ comprising:a flexible endoscope having a substantially non-circular cross-section, the endoscope including a plurality of chambers extending therein;a resection housing including a stapling mechanism and an anvil member moveable relative to one another between a tissue receiving position and a stapling position and an endoscope receiving channel extending therethrough, wherein the anvil member is mounted to the housing so that an angle of the anvil member relative to the stapling mechanism may be varied to alter a field of view of the endoscope when the endoscope is received within the endoscope receiving channel. 2. The system according to claim 1, wherein the plurality of chambers includes an insufflation chamber, an irrigation chamber, a lighting mechanism chamber and a viewing mechanism chamber. 3. The system according to claim 1, wherein cross-sections of the endoscope receiving channel and the endoscope are substantially non-circular. 4. The system according to claim 3, wherein the cross-sections of the endoscope receiving channel and the endoscope are substantially elliptical. 5. The system according to claim 1, wherein the stapling mechanism includes a plurality of staple firing chambers arranged around a periphery of the housing and wherein the anvil member includes a corresponding plurality of staple forming grooves arranged around a periphery thereof. 6. The system according to claim 1, wherein a cross-section of the housing is substantially elliptical. 7. The system according to claim 6, wherein the stapling mechanism includes a plurality of staple firing chambers arranged around a periphery of the housing and wherein the anvil member includes a corresponding plurality of staple forming grooves arranged around a periphery thereof. 8. The system according to claim 1, wherein the anvil member is coupled to the stapling mechanism by at least one mounting member slidably mounted within the housing and wherein the anvil member is pivotally mounted on a distal end of the at least one mounting member. 9. A resection housing for endolumenally resecting a full-thickness portion of tissue comprising:a stapling mechanism including a substantially non-circular endoscope receiving channel extending therethrough; andan anvil member moveably mounted to the stapling mechanism for movement relative thereto between a tissue receiving position and a stapling position, the anvil member including an endoscope viewing opening therethrough, wherein the anvil member is mounted to the stapling mechanism so that an angle of the anvil member relative to the stapling mechanism may be varied to alter a field of view through the endoscope viewing opening of an endoscope received within the endoscope receiving channel. 10. The housing according to claim 9, wherein the anvil member is substantially crescent shaped with an interior of the crescent forming the endoscope viewing opening, wherein the anvil member is pivotally coupled to at least one mounting member slidably received within the stapling mechanism. 11. The housing according to claim 10, wherein the stapling mechanism includes a plurality of staple firing channels opening to a distal face thereof and wherein the anvil member includes a corresponding plurality of staple forming grooves formed on a proximal face thereof so that, when in the stapling position, each of the staple firing channels faces a corresponding one of the staple forming grooves across a stapling gap. 12. The housing according to claim 10, wherein, when in the stapling position, the proximal face of the anvil member and the distal face of the stapling mechanism are substantially parallel to one another and wherein the anvil may be pivotted about the at least one mounting member to a viewing position in which a portion of a periphery of the endoscope viewing opening is moved toward the distal face of the stapling mechanism relative to a distal end of the at least one mounting member to increase a field of view therethrough.
