摘要:
The self securing suture includes a suture having a stiff end segment at a terminal end and a toggle disposed on the terminal end such that the stiff end segment and toggle define an acute angle between 25 degrees and 65 degrees. The toggle may be a metal or a biocompatible plastic. In one embodiment, a portion of the stiffened end segment is swaged onto the toggle in a closed channel. The present invention also includes methods for producing suture toggles. One method includes creating a partial channel on a toggle, stiffening an end segment of a suture thread, positioning a portion of the stiffened end segment in the partial channel, and swaging the toggle channel closed. The toggle and swaged suture thread may be coated with a biocompatible polymer. An alternative method of manufacture includes utilizing a tubular toggle, passing the stiffened end segment through the tube and swaging the toggle tube closed. In yet another method of manufacture for producing a suture toggle, a mold is utilized to form the toggle and the stiffened, positioned suture thread end segment.

The invention relates to a suture comprising a copolymer of a polyethylene glycol terephtalate and a polybutylene terephtalate, which copolymer comprises 45-60 wt. %, based on the weight of the copolymer, of the polyethylene glycol terephtalate, and 55-40 wt. %, based on the weight of the copolymer, of the polybutylene terephtalate.
摘要:
The present invention discloses a process for producing a braided suture having an improved knot strength comprising heating a braided suture coated with a low molecular weight biocompatible polymer to a temperature sufficient to melt the low molecular weight biocompatible polymer for a time sufficient to allow the low molecular polymer to be redistributed into the interstices of the braided suture thereby providing a coated braided suture with an improved knot tensile strength. Also disclosed is the coated braided suture having a low molecular weight polymer optimally dispersed throughout the braided suture's cross-section.
摘要:
A method of coating an implantable prosthesis by applying a composition including a therapeutic substance and a fluid to the prosthesis and removing the fluid is disclosed. The fluid is not capable of significantly dissolving the therapeutic substance. A second fluid in which the therapeutic substance is soluble may be further included in the composition. Methods of providing the composition and a roughened polymeric primer layer are also disclosed.
