Abstract
A biocompatible implant having improved host tissue ingrowth capability and enhanced blood compatibility comprises at least one tissue-contacting surface of an electrically charged material. The electrically charged material can be further chemically modified with covalently bonded activator molecules which further promote host tissue ingrowth and adhesion to the implant and/or enhance blood compatibility.
Claims19
A biocompatible orthopedic or dental implant comprising a prosthesis having at least one tissue-contacting surface of a negatively charged polymeric clectret material, said negatively charged polymeric electret material characterized by a bulk monopolar charge which produces an external electrostatic field, such that bone cell ingrowth and adherence to the prosthesis is promoted.
