Abstract
Abstract A locking catheter system including a flexible catheter having a restraining portion such as a pigtail, malecot rib or J-curve at its distal end and a flexible filament extending therefrom to attaching means at the other end of the catheter. The attaching means comprise a compressible suture-sealing bushing through which the flexible filament is passed and locked in place.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
99 words
A locking catheter system comprising: a flexible catheter having a restraining portion at its distal end; a flexible filament, extending from the restraining portion to the proximal end of the catheter, for drawing the restraining portion toward the proximal end; and means, at the proximal end of the catheter, for removably fixing the flexible filament in place after the restraining portion is drawn toward the proximal end, the fixing means comprising a compressible bushing having a longitudinal bore for sealingly and slidingly holding the flexible filament; and means for compressing the bushing to lock the flexible filament in place.
Claim 2
Dependent Claim
99 words
A locking catheter system comprising: a flexible catheter having a restraining portion at its distal end; a flexible filament, extending from the restraining portion to the proximal end of the catheter, for drawing the restraining portion toward the proximal end; and means, at the proximal end of the catheter, for removably fixing the flexible filament in place after the restraining portion is drawn toward the proximal end, the fixing means comprising a compressible bushing having a longitudinal bore for sealingly and slidingly holding the flexible filament; and means for compressing the bushing to lock the flexible filament in place.
