Embodiment Construction

[0050] Unless otherwise indicated, the practice of the present invention will be carried out using medical devices and methods conventional in the art. Such techniques are fully explained in the literature. All publications, patents and patent applications cited herein, whether above or below, are hereby incorporated by reference into this application in their entirety.

[0051] One aspect of the present invention relates to a biodegradable in vivo support device. The device includes a body formed from a biodegradable metal scaffold coated with a biodegradable polymer coating. Once placed in the body cavity, the polymer coating can cover the biodegradable metal scaffold long enough to allow the device to be encapsulated in the surrounding tissue, thereby enabling segments of the biodegradable metal scaffold to be used during treatment In situ degradation and absorption.

[0052] The biodegradable in vivo support devices include, but are not limited to, vascular support devi...

Abstract

The invention discloses a biodegradable stent device. The biodegradable stent device comprises a biodegradable metal stent and a biodegradable polymer coating, and at least part of the biodegradable metal stent is coated with the biodegradable polymer coating. The degradation rate of the biodegradable polymer coating is higher than that of the biodegradable metal stent.

Description

[0001] This application is a division of an invention patent application with the application number of 201280068585.X (international application number: PCT / US2012 / 028448), the application date is March 9, 2012, and the invention name is "biodegradable support device" Application. technical field [0002] The present application relates generally to medical devices, and in particular, to a biodegradable in vivo support device. Background technique [0003] In vivo support devices or barrier devices, such as stents, are artificial "tubes" or "frames" that are inserted into natural channels or conduits in the body to prevent or obstruct local flow obstructions or outflows that cause disease, such as leaks or aneurysms. Support devices include vascular support devices, non-vascular support devices, and heart failure closure or aneurysm closure devices. Vascular support devices are designed for use within vasculature such as arteries and veins. Non-vascular support devices ar...
