Biodegradable, polymer coverings for breast implants
First Claim
1. A biodegradable covering for a breast implant, said biodegradable covering comprising one or more biodegradable polymer layers with elastomeric properties said biodegradable covering having a Tg of less than about 40°
- C., and an outer surface, an inner surface for non-adherent contact with an outer surface of said breast implant, and a flexible opening allowing insertion of said breast implant through said flexible opening into said biodegradable covering such that when said breast implant is disposed within said biodegradable covering said inner surface of said biodegradable covering is in contact with but not adhered to said breast implant, said one or more biodegradable polymer layers include one or more drugs consisting of antimicrobial agents, and at least one of an anesthetic and anti-inflammatory agent.

Abstract
A biodegradable, flexible covering for a breast implant is provided which comprises one or more biodegradable polymer layers dimensioned and shaped to cover at least a portion of the breast implant. The implant can be inserted into an opening of the covering immediately prior to surgery, but alternate configurations and times of insertion are contemplated as well as open or sheet type devices. The coverings can optionally contain one or more drugs for delivery at the surgical site, particularly for treating or preventing infection, pain, inflammation, capsular contracture, scarring or other complications associated with breast augmentation or breast reconstruction.

13. A breast implant assembly comprising:
-
a biodegradable covering having elastomeric properties and a Tg of less than about 40°
C., said biodegradable covering include one or more drugs consisting of antimicrobial agents, and at least one of an anesthetic and anti-inflammatory agent; anda breast implant, said breast implant and said biodegradable covering being preassembled such that said breast implant is disposed within at least a portion of said biodegradable covering, said biodegradable covering being in contact with but not adhered to said breast implant whereby said breast implant can move relative to said biodegradable covering when said breast implant is disposed within said biodegradable covering.

- 14. A biodegradable covering for a breast implant, said biodegradable covering comprising one or more biodegradable polymer layers comprising a sheet, film or mat of nanofibers, and including an outer surface and an inner surface for non-adherent contact with an outer surface of said breast implant, whereby said inner surface of said biodegradable covering can be in contact with but not adhered to said breast implant, said one or more biodegradable polymer layers include one or more drugs consisting of antimicrobial agents, and at least one of an anesthetic and anti-inflammatory agent.
- 20. A biodegradable covering for a breast implant comprising a plurality of biodegradable polymer layers having elastomeric properties, said biodegradable covering having an outer surface, an inner surface for contact with an outer surface of said breast implant, and a flexible opening allowing insertion of said breast implant through said flexible opening in said biodegradable covering, said plurality of biodegradable polymer layers including a first biodegradable polymer layer comprising said inner surface and comprising a drug-impermeable biodegradable barrier layer for preventing drugs from contacting said breast implant when said breast implant is disposed within said biodegradable covering, and including at least one additional biodegradable polymer layer including one or more drugs whereby a predetermined drug release profile for said biodegradable covering can be provided wherein said one or more drugs consists of antimicrobial agents, and at least one of an anesthetic and anti-inflammatory agent.
