The present invention relates to the prevention and treatment of implant associated complications; e.g. foreign body response (FBR). High mechanical stress at the implant-tissue interface activates a sustained inflammatory response, which is primarily responsible for implant associated complications and implant failure. In particular, described herein are apparatuses, devices, and compositions containing inhibitors of mechanotransduction, and methods of making and using such apparatuses, devices and compositions. These apparatuses, devices, compositions, and methods are useful for preventing or reducing unwanted fibrosis, inflammation or cancer that result from implantation of a biomedical implant in an individual. One aspect of the invention provides a biomedical device including an effective amount of a composition containing a mechanotransduction inhibitor for preventing, inhibiting or treating implant associated complications.

Described embodiments are directed toward centrally-opening leaflet prosthetic valve devices having synthetic leaflets that are configured to promote and encourage tissue ingrowth thereon and/or therein. The leaflets are coupled to a leaflet frame to form a prosthetic valve suitable for use in biological anatomy.

The present invention provides methods for identification of distinct macrophage subsets which demonstrate previously unrecognized myeloid macrophage phenotypes involved in different tissue responses and provide new methods for therapeutic modulation of certain pathologic tissue states and tissue repair.

The disclosure features surface coatings formed from dimeric steroid prodrugs for the extended delivery of a drug from a surface, and for the treatment of a disease or condition. Also provided herein are drug depots formed from dimeric steroid prodrugs for the extended delivery of a drug for use in combination with implantable medical devices. Said dimeric steroid prodrugs are represented by the formula D1-L-D2, wherein D1 and D2 are independently a steroid radical and L is a linker covalently linking D1 to D2.

An implantable medical device comprising (a) a metallic substrate and (b) a bisphosphonate wherein both phosphorus atoms contained in the bisphosphonate are covalently attached to a same carbon atom. The bisphosphonate continuously coats the external surface of the metallic substrate as monolayer and as outermost layer. At least one phosphonate moiety of the bisphosphonate is covalently and directly bonded to the external surface of the metallic substrate and/or covalently bonded to another molecule of the bisphosphonate in the coating.

An implantable medical device includes a polymer substrate and at least one nanofiber. The polymer substrate includes a surface portion extending into the polymer substrate from a surface of the substrate. The at least one nanofiber includes a first portion and a second portion. The first portion is interpenetrated with the surface portion of the substrate, and mechanically fixed to the substrate. The second portion projects from the surface of the substrate.
