Robert E Fischell, David R Fischell, Tim A Fischell: Method for accessing the coronary arteries from the radial or brachial artery in the arm. Cathco, February 20, 1996: US05492530 (72 worldwide citation)

The present invention is a method for using an improved guiding catheter that eliminates the need for an introducer sheath or a separate Tuohy-Borst "Y" adaptor, thus reducing the time and expense for performing artery opening procedures. Furthermore, the guiding catheter with straightening dilator ...

Robert E Fischell, David R Fischell: Multifold balloon for stent deployment. IsoStent, August 11, 1998: US05792172 (72 worldwide citation)

The present invention utilizes a balloon with three or more folds to more evenly distribute the frictional forces on the inside of a stent during stent deployment thus improving the uniformity of stent cell expansion. Ideally one would like to have the same number of balloon folds as the number of s ...

Robert E Fischell: Dottering auger catheter system and method. Cathco, November 23, 1993: US05263959 (67 worldwide citation)

The Dottering Auger Catheter system is designed for penetration of tight stenoses or total occlusions (called blockages) as a precursor to balloon angioplasty, atherectomy, or any other vessel opening means that requires an initial passageway. Specifically, the Dottering Auger Catheter system consis ...

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 ...

Antonio Columbo, Robert E Fischell: Radioisotope stent with non-radioactive end sections. IsoStent, August 8, 2000: US06099455 (57 worldwide citation)

A radioisotope stent that is made radioactive for most of the stent's length at a center section of the stent, but is not radioactive for a limited length at each end section of the stent. Such a stent design would have a negligible radiation level at the extreme ends of the stent. Therefore, there ...
