Filed:

Dec 11, 2001

Appl. No.:

10/014705

Inventors:

Scott Addonizio - Fort Lauderdale FL, US
David Camp - Hillsboro Beach FL, US
Gary Becker - Miami FL, US
John Pazienza - Pompano Beach FL, US

International Classification:

A61F002/06

US Classification:

623/001150

Abstract:

An expandable stent comprised of a plurality of helical segments is disclosed. In one embodiment, the stent is generally cylindrical in shape having a cylindrical axis, and the comprises at least two a first and second set of helical segments. The helical segments in the first set are substantially parallel and have a first pitch forming a first helical angle with respect to the cylindrical axis. The helical segments in the second set are also generally parallel to each other and form a second pitch that differs from the first pitch, thereby forming a second helical angle with respect to the cylindrical axis. In an alternative embodiment, the stent comprises one set of helical segments and a plurality of circumferential elements that are joined together by the helical segments to form a plurality of cylindrical elements which are joined together to form a stent body. The stent may also have endzones.

International Classification:

A61F002/06

US Classification:

623/001420, 427/002100

Abstract:

A drug eluting medical device is provided for implanting into vessels or luminal structures within the body of a patient. The coated medical device, such as a stent, vascular, or synthetic graft comprises a coating consisting of a controlled-release matrix of a bioabsorbable, biocompatible, bioerodible, biodegradable, nontoxic material, such as a Poly(DL-Lactide-co-Glycolide) polymer, and at least one pharmaceutical substance, or bioactive agent incorporated within the matrix or layered within layers of matrix. In particular, the drug eluting medical device when implanted into a patient, delivers the drugs or bioactive agents within the matrix to adjacent tissues in a controlled and desired rate depending on the drug and site of implantation.
