Embodiment Construction

[0102] Disclosed herein are novel structural elements and novel compositions that can be used to prepare such novel structural elements. Embodiments of the present invention are useful in the treatment of a variety of diseases and physiological conditions.

[0103] In recent years, metal stents have been used to help clear clogged lumens of the vasculature. However, certain adverse results have reduced the effectiveness of metal stent grafts in arterial vessels. For example, because such stents have been shown to stimulate the tendency to form scar tissue or restenosis in wounds in the region of the vessel in which they are placed. This effect becomes more deleterious with treatments using small diameter tubing. In addition, it is important to avoid damage to the arterial wall during stent insertion. The purpose of these factors, although somewhat difficult to control in the first case, is to attempt to reduce the mechanical causes of excess clot and scar formation in the v...

Abstract

In embodiments there is described a cardiovascular tube-shaped lockable and expandable bioabsorbable scaffold having a low immunogenicity manufactured from a crystallizable bioabsorbable polymer composition or blend.

Description

[0001] This application claims priority under 35 U.S.C. §119(e) to U.S. Provisional Application No. 61 / 195,859, filed October 10, 2008. References cited in this specification, and references cited in those documents - where appropriate to teach additional or alternative details, characteristics and / or technical background - are hereby incorporated by reference in their entirety. technical field [0002] The present invention relates to polymeric medical devices for implantation in luminal structures in the body. Specifically, the medical device comprises a polymeric structure, wherein the polymer is bioabsorbable, biocompatible and structurally configured for use in a luminal structure in the body, such as a blood vessel. Such medical devices are useful in the treatment of diseases such as atherosclerosis, restenosis and other types of small tube infarction. Background technique [0003] Embodiments herein disclose a novel medical device, such as an expandable tubular cardi...
