DRUG DELIVERY DEVICE FOR PERIPHERAL ARTERY DISEASE

摘要

A medical device implantable within a peripheral vessel of the body composed of a bioresorbable polymer is disclosed. The device has a high resistance to fracture, is very flexible, and has a high crush recovery when subjected to crushing, axial, or torsional forces.

主权项

1. A medical device implantable within a peripheral vessel of the body, comprising:
a cylindrical radially expandable body formed from a polymer formulation comprising a bioresorbable elastic material greater than 60 wt % of the body and a bioresorbable rigid material less than 40 wt % of the body which form rigid domains dispersed throughout a matrix of the elastic material, and an anti-restenosis drug associated with the body for delivery to the vessel upon implantation of the medical device in the peripheral vessel, wherein the elastic material has a glass transition temperature (Tg)<25 deg C. and the rigid polymer or segment has a Tg greater than 37 deg C., and wherein the body is configured to be expanded from a crimped state to an expanded state within the peripheral vessel in contact with the vessel wall.
