Abstract
The tie-down characteristics of braided sutures are improved by applying to the surface thereof a polymeric ester of a dibasic acid and a glycol.
Claims16
A suture having improved tie-down performance comprising a multifilament, the outer surface of the multiflament being coated with from about 0.4 percent to about 7 percent based on suture weight of an aliphatic polyester that is a solid at room temperature;
- said polyester having from 2 carbon atoms to about 12 carbon atoms between the ester linkages in the polymer chain and said polyester having a molecular weight in the range of 1,000 to 15,000.
The multifilament suture of cliam 6, wherein the polyester coating has a molecular weight of about 2,000.
