Abstract
An implant having an adhesive structure comprising a planar surface having two sides and rectangular cuboid-based protrusions having pyramidal tips extending from at least one of said sides, optionally having a porous basic supporting structure, and methods of making and using such implants.
Claims64
An adhesive structure comprising a planar surface having two sides and rectangular cuboid-based protrusions having pyramidal tips extending from at least one of said sides.
A process for making an adhesive structure, comprising:
- providing a mold having multiple rectangular cuboid-based indentations having pyramidal tips extending below a planar surface;
- applying a melt processable polymer to said mold under temperature and pressure conditions sufficient to fill said indentations and said planar surface to form a first molded adhesive structure having a planar surface and rectangular cuboid-based protrusions having pyramidal tips extending below said planar surface;
- and
- removing said molded adhesive structure from said mold.
A surgical procedure comprising:
- inserting into a patient at a surgical repair site an implant comprising an adhesive structure comprising a planar surface having two sides and rectangular cuboid-based protrusions having pyramidal tips extending from at least one of said sides;
- approximating edges of the surgical repair site;
- and
- pressing said adhesive structure against the surgical repair site.
A surgical procedure comprising:
- inserting into a patient at a surgical repair site an implant comprising an adhesive structure comprising a planar surface having two sides and rectangular cuboid-based protrusions having pyramidal tips extending from at least one of said sides;
- approximating edges of the surgical repair site;
- and
- pressing said adhesive structure against the surgical repair site substantially without mechanical fixation of the device.
A process for making an adhesive structure, comprising:
- providing a mold having multiple rectangular cuboid-based indentations having pyramidal tips extending below a planar surface;
- applying a melt processable polymer film to said planar surface;
- applying a porous basic structure onto said polymer film;
- applying a sufficient pressure and temperature to said porous basic structure and said polymer film to force a portion of said film into said indentations and to simultaneously laminate said porous basic structure to said film;
- and
- removing said molded adhesive structure from said mold.
An adhesive structure comprising a perforated planar surface having two sides and protrusions extending from at least one of said sides.
