Abstract

A tubular implant to be used for percutaneously feeding a patient, which implant is made of resiliently deformable material and includes a distal enlargement adapted to be inserted into the stomach and having at least one opening and a proximally following central tubular section adapted to be inserted into a punctured hole extending from the outside into the stomach cavity, characterized in that the implant includes releasable tensioning or pinching means for reversibly reducing the diameter of the implant along its total length such that it is freely displaceable together with said means through a usual trocar sleeve.

Claims

1. A tubular implant to be used for percutaneously feeding a patient, said implant being constructed of resiliently deformable material and includes a distal enlargement adapted to be inserted into the stomach and having at least one opening, said distal enlargement having a distal abutment, a proximally following central tubular section adapted to be inserted into a punctured hole extending from the outside into the stomach cavity, and an enlarged proximal end having a proximal abutment, characterized in that the implant includes a proximal and a distal end and releasable tensioning means comprising a stretch rod which is disposed between and bears against said abutments at the proximal and distal ends of the implant for reversibly reducing the diameter of the implant along its total length such that it is freely displaceable together with said means through a trocar sleeve.
