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.
