Absorbable implants for breast surgery that conform to the breast parenchyma and surrounding chest wall have been developed. These implants support newly lifted breast parenchyma, and/or a breast implant. The implants have mechanical properties sufficient to support a reconstructed breast, and allow the in-growth of tissue into the implant as it degrades. The implants have a strength retention profile allowing the support of the breast to be transitioned from the implant to regenerated host tissue, without significant loss of support. Three-dimensional implants for use in minimally invasive mastopexy/breast reconstruction procedures are also described, that confer shape to a patient's breast. These implants are self-reinforced, can be temporarily deformed, implanted in a suitably dissected tissue plane, and resume their preformed three-dimensional shape. The implants are preferably made from poly-4-hydroxybutyrate (P4HB) and copolymers thereof. The implants have suture pullout strengths that can resist the mechanical loads exerted on the reconstructed breast.

Compositions useful as dermal fillers and methods using such compositions to treat various skin and soft tissue conditions. The dermal fillers can comprise silk attached to hyaluronic acid using for example two cross linkers and can be used to treat of facial imperfections, facial defects, facial augmentations, breast imperfections, breast augmentations or breast reconstructions.

An implant material having an implant surface comprising a plurality of tissue-contacting members arranged in a regular or irregular two-dimensional array, each tissue-contacting member having a convex curved tissue-contacting surface. Methods of preparing and using such implant materials.

Disclosed are a composition for surface modification of a medical implant and a medical implant surface-modified thereby, and according to a medical implant according to one embodiment, itaconic acid may be bound to the surface of the medical implant with high binding stability, and fibrosis inhibition and inflammatory response inhibition effects at an implantation site are exhibited.

A resorbable polymeric mesh implant whose implant configuration varies over time after implantation for use in breast reconstruction, wherein the resorbable polymeric mesh implant comprises at least a first material and a last-degraded material, wherein the last-degraded material is substantially degraded at a later point in time in the body than the first material. The modulus of elasticity of the last-degraded material is significantly lower than the modulus of elasticity of the first material. The last-degraded material has a modulus of elasticity that corresponds to an elongation of 18 to 32% when subjected to a tensile load of 16 N/cm. The resorbable polymeric mesh implant is tubular and configured to retain a breast implant.
