Abstract
A prosthetic ligament implant is sheathed at one end in the sock in order to facilitate pulling of the implant through a hole drilled in a bone. The sock is provided with a separable proximal portion which does not envelope the implant and which can be cut off after pulling of the implant through the hole in the bone. With removal of the proximal portion, the remaining textile structure of the sock becomes asunder so that the sock can be readily pulled off from the end of the implant.
Claims8
In combination
- an implant comprising a plurality of longitudinal parallel threads, at least a portion of each of said threads being free to move independently of each of the other threads;
- and
- a textile sock for holding said threads next to one another during insertion of the implant, said sock having an intermediate portion extending concentrically about said threads, a distal portion extending coaxially from said intermediate portion and said implant for passage through a bore in a bone, and a proximal portion extending from said intermediate portion laterally of said implant.
In combination
- an implant comprising a plurality of longitudinal parallel threads;
- and
- a textile sock having an intermediate portion extending concentrically about said threads, said threads being of different length within said intermediate portion of said sock to form a conically tapered shape, a distal portion extending coaxially from said intermediate portion and said implant for passage through a bore in a bone, and a proximal portion extending from said intermediate portion laterally of said implant.
In combination
- an implant comprising a plurality of longitudinal parallel threads;
- and
- a textile sock having an intermediate portion extending concentrically about said threads, said threads forming an eye in said intermediate portion of said sock, a distal portion extending coaxially from said intermediate portion and said implant for passage through a bore in a bone, and a proximal portion extending from said intermediate portion laterally of said implant.
