Abstract
Described herein are open celled foams including a matrix of interconnected spheres. Also described herein are methods of making open celled foams as well as making composite members with open celled foam coatings covering at least a portion of the composite member. The open celled foams described herein are silicone based materials and can be used to coat implants such as breast implants and function to encourage tissue ingrowth and reduce capsular formation.
Claims9
A soft tissue implant comprising:
- a textured coating on at least a portion of said implant, said coating comprising a matrix of interconnected spheres having a physical void space of about 50% to about 70%, said spheres comprising substantially pure silicone.

- a textured coating on at least a portion of said implant, said coating comprising a matrix of interconnected spheres having a theoretical void space of between about 60% and about 88%, said spheres comprising substantially pure silicone.
A breast implant comprising:
- a fillable elastomeric shell;
- and
- a textured coating on at least a portion of said shell, said coating comprising a matrix of interconnected spheres having a having a physical void space of about 50% to about 70%, said spheres comprising substantially pure silicone.
A breast implant comprising:
- a fillable elastomeric shell;
- and
- a textured coating on at least a portion of said shell, said coating comprising a matrix of interconnected spheres having a theoretical void space of between about 60% and about 88%, said spheres comprising substantially pure silicone.
