Medical devices are disclosed which are adapted for indwelling placement in a patient. In one device, a flexible tubular catheter is adapted for placement with its distal end inside of the body and its proximal end outside of the body, and defines a lumen which provides a fluid passageway between its proximal and distal ends. The flexible tubular member has multiple engagement elements located on its outside surface, and an external bolster is provided which includes multiple engagement elements complementary to the engagement elements located on the tubular catheter for adjustably coupling the bolster and the tubular catheter. After placement, the bolster locks to the tubular member such that the bolster can rest securely close to the skin surface. In a first disclosed embodiment, a compression element locks the bolster to the tubular member after selective positioning of the bolster onto the tubular member. In a second embodiment, the bolster has a curved passageway which opens to a side port, and the bolster lumen has engagement elements about the curved passageway which are complementary to the engagement elements located on the tubular member. The bolster is locked into position by the tension between engaged engagement elements caused by the bending of the flexible tubular member in the curved passageway within the side-port bolster. In this way, the bolster is capable of being selectively positioned and locked onto the tubular member to allow the bolster to rest closely to the skin surface without requiring an additional compression element.

A medical device adapted for indwelling placement in a patient comprising: a flexible tubular member having a proximal end and a distal end, wherein said distal end is adapted for placement inside of a body of the patient in a normal implanted orientation and said proximal end is adapted for placement outside of the body; said tubular member further defining a lumen which provides a fluid passageway between said proximal and said distal ends: said flexible tubular member further having multiple engagement elements located on an outside surface; a separate external coupling incorporating at least one matching engagement element capable of selective engagement with at least one of said multiple engagement elements on the outside surface of said tubular member to selectively position said coupling on said tubular member such that said coupling rests close to a skin surface outside the body; means for locking said coupling to said tubular member after selective positioning of said coupling on said tubular member to rest securely close to the skin surface to prevent said engaged engagement elements on both said coupling and said tubular member from disengagement such that said coupling and tubular member become fixed together to prevent inward migration of the tubular member within the body and wherein said coupling defines a curved passageway having a proximal end and a distal end and said coupling includes multiple matching engagement elements positioned within said curved passageway including at least one aligned-oriented engagement element in the distal end of said curved passageway which defines means for selective engagement with at least one of said multiple engagement elements on the outside surface of said tubular member in an aligned orientation relative to the normal implanted orientation and at least one side-oriented engagement element in the proximal end of said curved passageway which defines means for selective engagement with at least one of said multiple engagement elements on the outside surface of said tubular member in a non-aligned orientation relative to the normal implanted orientation and wherein said locking means includes tension between at least one of said engaged engagement elements of said tubular member with said at least one side-oriented engagement element of said coupling caused by bending of said flexible tubular member within said curved passageway.
