Abstract:

Methods of forming a coating onto an implantable device or endoluminal prosthesis, such as a stent, are provided. The coating may be used for the delivery of an active ingredient. The coating may have a selected pattern of interstices for allowing a fluid to seep through the coating in the direction of the pattern created.

Assignee:

Advanced Cardiovascular Systems, Inc. - Santa Clara CA

International Classification:

A61F 206

US Classification:

623 142

Abstract:

An implantable stent for a vessel includes a tubular body having an inner and outer surface. The inner and outer surfaces are coated with therapeutic substances. The therapeutic substance of the inner surface, such as an angiogenic substance, can be released downstream in the lumen. The therapeutic substance of the outer surface can be applied to the inner surface of the vessel.

Assignee:

Advanced Cardiovascular Systems, Inc. - Santa Clara CA

International Classification:

A61F 2/00

US Classification:

424423

Abstract:

A prodrug comprising a heparin and a drug is provided. The prodrug can be used to form a coating on a medical device. The prodrug can also be used with a polymeric material to form a coating on a medical device. The polymeric material can be a hydrophobic polymer, a hydrophilic polymer, a non-fouling polymer, or combinations thereof. The medical device can be implanted in a human being for the treatment of a disease such as atherosclerosis, thrombosis, restenosis, hemorrhage, vascular dissection or perforation, vascular aneurysm, vulnerable plaque, chronic total occlusion, claudication, anastomotic proliferation for vein and artificial grafts, bile duct obstruction, ureter obstruction, tumor obstruction, or combinations thereof.

Abstract:

Provided herein is a copolymer that includes a soft block (A) that contains poly(ester amide) (PEA) and a hard block (B). The copolymer can be any of AB, ABA or BAB type block copolymers. By varying the relative amount of the PEA block and the hard block, one can obtain a copolymer with a Tfor mechanical integrity in drug-delivery stent applications. The copolymer can be used alone or optionally in combination with a biobeneficial material and/or a biocompatible polymer to form an implantable device or a coating on an implantable device. When the copolymer is used in combination with a biobeneficial material, the copolymer and the biobeneficial material can be co-deposited or applied in sequence during the coating process. A coating formed of the copolymer may also include a bioactive agent. The implantable device can be implanted in a patient to treat, prevent, or ameliorate a disorder such as atherosclerosis, thrombosis, restenosis, hemorrhage, vascular dissection or perforation, vascular aneurysm, vulnerable plaque, chronic total occlusion, claudication, anastomotic proliferation for vein and artificial grafts, bile duct obstruction, ureter obstruction, and/or tumor obstruction.
