Robert E Fischell, Tim A Fischell: Intra-arterial stent with the capability to inhibit intimal hyperplasia. Medical Innovative Technologies R & D Partnership, October 22, 1991: US05059166 (351 worldwide citation)

Intra-arterial stents are frequently used subsequent to balloon angioplasty to maintain arterial patency. The most frequent cause for failure to maintain patency is the rapid growth of the injured arterial tissue through the openings in the stent, which rapid growth is called "intimal hyperplasia." ...

Robert E Fischell, Tim A Fischell: Endoluminal tissue excision catheter system and method. Medical Innovative Technologies R&D Partnership, April 30, 1991: US05011490 (57 worldwide citation)

An Endoluminal Tissue Excision Catheter (ETEC) is described which is capable of excising obstructive tissue from a vessel in a living body. The ETEC system operates by first passing a guide wire through the vessel and beyond the obstructive tissue. The ETEC catheter is then advanced over the guide w ...
