Claims17
A copolymer formed by reacting
- a) 5 to 80 weight percent of a prepolymer of p-dioxanone and a monomer selected from the group consisting of lactide, glycolide and combinations thereof, which has a melting point of less than 120.degree. C.;
- b) with p-dioxanone to obtain a copolymer with an inherent viscosity in the range of from about 0.8 to about 3.0 dL/g in a 0.1 g/dL solution of hexafluoroisopropyl alcohol at 25.degree. C.
An absorbable surgical filament prepared from a copolymer formed by reacting
- a) 5 to 80 weight percent of a prepolymer of p-dioxanone and a monomer selected from the group consisting of lactide, glycolide and combinations thereof, which has a melting point of less than 120.degree. C.;
- b) with p-dioxanone to obtain a copolymer with an inherent viscosity in the range of from about 0.8 to about 3.0 dL/g in a 0.1 g/dL solution of hexafluoroisopropyl alcohol at 25.degree. C.
A surgical device prepared from a copolymer formed by reacting
- a) 5 to 80 weight percent of a prepolymer of p-dioxanone and a monomer selected from the group consisting of lactide, glycolide and combinations thereof, which has a melting point of less than 120.degree. C.;
- b) with p-dioxanone to obtain a copolymer with an inherent viscosity in the range of from about 0.8 to about 3.0 dL/g in a 0.1 g/dL solution of hexafluoroisopropyl alcohol at 25.degree. C.
- wherein the surgical device is selected from the group consisting of surgical meshes, surgical staples, hemostatic clips, and suture knot clips.
