Abstract
The present disclosure relates to implantable medical devices including swellable tissue gripping elements and methods of forming such devices. The implantable medical device may comprise a biocompatible substrate having a surface comprising at least one swellable grip member. The implantable medical device may take on the form of a surgical mesh, patch, buttress, or pledget and the swellable member may comprise spikes and/or spiked naps. The implantable medical device may also contain a bioactive agent.
Claims20
An implantable medical device comprising a biocompatible substrate having a surface comprising at least one swellable grip member.
The implantable medical device of claim 16 wherein the bioactive agent is selected from the group consisting of anti-adhesives, antimicrobials, analgesics, antipyretics, anesthetics, antiepileptics, antihistamines, anti-inflammatories, cardiovascular drugs, diagnostic agents, sympathomimetics, cholinomimetics, antimuscarinics, antispasmodics, hormones, growth factors, muscle relaxants, adrenergic neuron blockers, antineoplastics, immunogenic agents, immunosuppressants, gastrointestinal drugs, diuretics, steroids, lipids, lipopolysaccharides, polysaccharides, platelet activating drugs, clotting factors, enzymes, and combinations thereof.
A method of forming an implantable medical device comprising:
- providing at least one swellable filament;
- and
- combining the at least one swellable filament with a biocompatible substrate to form swellable grip members along a surface of the biocompatible substrate.
(canceled)
A method of forming an implantable medical device having swellable barbed and spiked naps comprising:
- providing a biocompatible substrate having swellable loops protruding perpendicularly from a surface of the biocompatible substrate;
- forming barbs on the swellable loops of the medical device;
- and
- treating a portion of the loops to melt and separate each loop into two swellable barbed and spiked naps.
