Abstract
Abstract A suture formed of loosely woven or expanded plastic material, one end of which is swaged to a suturing needle. Upon emplacement in the body, the suture acts initially to hold the tissues in place in a conventional manner. Thereafter it acts to bring about the formation by natural body processes of ligamentous tissue about the suture which supplements and virtually replaces the suture. The suture may be in small diameter tubular form or in small width flat form.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
154 words
A suture for attachment to a conventional suture needle for use within a human or animal body, said suture having a minimal outer dimension substantially comparable to that of said needle, said suture having sufficient physical strength to hold together for an extended period of time the members through which it passes, said suture being formed of loosely woven or expanded plastic material having a substantial degree of microporosity sufficient so that upon emplacement within the body said suture becomes penetrated with newly formed ligamentous tissues generated by the body, which ligamentous tissues are adapted to initially act to supplement and reinforce the physical holding action of said suture and which ligamentous tissues over an extended period of time are adapted to replace said suture and thereafter function in place of said suture to physically hold together the members through which said suture initially passed in complete replacement of said suture and its function.
Claim 2
Dependent Claim
154 words
