Bioabsorbable mesh for surgical implants
View Patent ↗Described are methods, devices, and systems related to pelvic implants, including implants that include absorbable and non-absorbable materials.
1. An implantable mesh for the treatment of a pelvic condition comprising:
a knitted structure comprising non-absorbable fibers, wherein the non-absorbable fibers are interwoven and form a plurality of courses in the structure, wherein a course in the structure comprises a series of adjacent loops, each loop having a surface, and the structure comprises coated absorbable material present on a portion of the surface of each adjacent loop in a course, wherein the absorbable material provides stiffening of the structure in one direction.
2. The implantable mesh of claim 1 wherein the structure comprises two courses that are adjacent to the course that comprises the series of adjacent loops with coated absorbable material, wherein the adjacent courses do not have a coating of absorbable material.
3. The implantable mesh of claim 1 wherein the coating is formed as an arc on each adjacent loop in a course.
4. The implantable mesh of claim 3 wherein the coating is formed as a semicircle on each adjacent loop in a course.
5. The implantable mesh of claim 1 , wherein each adjacent loop has an outer diameter, and the coating is formed on a portion of the outer diameter of each adjacent loop.
6. The implantable mesh of claim 1 wherein the coated absorbable material comprises a polymer selected from the group consisting of polyhydroxyalkanoate, poly-L-lactic acid, polyanhydride, polycaprolactone, polyglycolic acid, poly-L-lactic acid, poly-D-L-lactic acid, polydioxanone, and polyphosphate ester.
7. The implantable mesh of claim 6 wherein the coated absorbable material comprises polyhydroxyalkanoate.
8. The implantable mesh of claim 1 wherein the non-absorbable fibers comprises polypropylene.
9. The implantable mesh of claim 1 which is a weft knitted structure.
10. The implantable mesh of claim 1 comprising a tissue support portion and extension portions connected to the support portion, wherein the support portion comprises the knitted structure with non-absorbable fibers and coated absorbable material on adjacent loops in the course.
11. The implantable mesh of claim 1 comprising a tissue fastener.
12. A method of treating a pelvic condition by supporting tissue of a pelvic region, the method comprising
implanting the implantable mesh of claim 1 in a patient to support tissue of a pelvic region to treat the pelvic condition.
