Robert E Fischell, David R Fischell: Stent with improved radiopacity and appearance characteristics. IsoStent, March 4, 1997: US05607442 (359 worldwide citation)

A stent (10) is plated with a high density, radiopaque metal (or alloy) such as gold or tantalum. Specifically, the stent (10) is plated to a sufficient thickness (15) on its longitudinal wires (12) to make it clearly radiopaque in fluoroscopy, but the generally circumferential wires (11) are plated ...

Janet W Burpee, David R Fischell: Intravascular stent with enhanced rigidity strut members. IsoStent, June 22, 1999: US05913895 (216 worldwide citation)

Disclosed herein is a thin-walled cylindrical stent in which one or more of the sets of strut members are more radially rigid after stent expansion as compared to other sets of strut members. Each set of strut members consists of a multiplicity of structural struts that are connected together with t ...

Robert E Fischell, Michael E Kopp: Means for accurately positioning an expandable stent. IsoStent, September 23, 1997: US05669932 (208 worldwide citation)

One aspect of the present invention envisions two radiopaque marker bands located within the balloon of the balloon angioplasty catheter for balloon expandable stents, or located at a distal portion of a stent delivery catheter designed for self-expanding stents. When the balloon is expanded to its ...

Robert E Fischell, David R Fischell, Tim A Fischell: Temporary radioisotope stent. IsoStent, January 11, 2000: US06013019 (159 worldwide citation)

The temporary radioisotope stent catheter system of the present invention includes a temporary radioisotope stent that is situated at a distal portion of two, co-axially situated, thin-walled tubes. The catheter system can be delivered into a vessel of a human body either as a stand-alone device or ...

Robert E Fischell, David R Fischell, Tim A Fischell: Radioisotope stent with increased radiation field strength at the ends of the stent. IsoStent, November 24, 1998: US05840009 (124 worldwide citation)

Disclosed is a radioisotope stent that has increased radioactivity at the end regions of the stent as compared to the stent's central region. To minimize the neointimal hyperplasia that may exist to a greater extent at the ends of a stent that is implanted into an artery of a human body, the amount ...

Robert E Fischell, David R Fischell: Multifold balloon for stent deployment. IsoStent, August 11, 1998: US05792172 (71 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 ...

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 ...

Robert E Fischell, David R Fischell, Tim A Fischell: Stent delivery catheter with enhanced balloon shape. IsoStent, April 24, 2001: US06221043 (50 worldwide citation)

Disclosed is a balloon on a distal portion of a balloon angioplasty catheter. The section of the balloon onto which a stent can be mounted has a central segment that is substantially cylindrical in shape that is centered between two segments each having the shape of a sector of a prolate spheroid. T ...
