Embodiment Construction

[0053] The polymer compositions of the present invention are useful in the preparation of medical devices to be implanted in patients. The medical device is a scaffold with biodegradable, bioabsorbable properties, and includes, but is not limited to, stents, stent grafts, vascular synthetic grafts, catheters, shunts, vascular shunts, valves , grafts, etc.

[0054] The present invention also relates to methods of making biodegradable polymer compositions, and methods of making said medical devices from the polymer compositions disclosed herein.

[0055] In one embodiment, the medical device includes a collapsible polymeric scaffold that can be inserted into a balloon delivery system for implantation. The air cells may comprise thermal or non-thermal cells. The medical device may have a structure that is collapsible during loading and expandable and stress-free under physiological conditions. The medical device may comprise structures comprising polymers that are orientable a...

Abstract

A method for fabricating an embodiment of a medical device comprising the steps of: preparing a biodegradable polymeric structure; coating the biodegradable polymeric structure with a polymeric coat including a pharmacological or biological agent; cutting the structure into patterns configured to allow for crimping of the cut structure and expansion of the cut structure after crimping into a deployed configuration.

Description

Background technique [0001] All references cited in this specification and their references are hereby incorporated by reference in their entirety where appropriate for teaching additional or alternative details, features and / or technical background. [0002] The present invention relates to a medical device for implanting a vessel or lumen structure in the body. In one embodiment, the invention relates to stents and synthetic grafts coated with a controlled release matrix comprising a pharmaceutical substance for direct delivery to surrounding tissue, and attached thereto for Ligands that capture endothelial progenitor cells on the blood-contacting surface of the device to form mature, functional endothelium at the site of injury. In particular, the polymer matrix / drug / ligand coated devices (such as stents) are useful, for example, in the treatment of diseases and conditions (such as restenosis, atherosclerosis) and in intraluminal reconstruction therapy. [0003] Disclosed...
