Problems solved by technology

[0009] The continued risk of stent thrombosis after implantation due to the persistence of the metal support tube has not been overcome by means of coating the metal structure with a pharmaceutical composition created to avoid said problem
On the contrary, these coatings resulted in extremely high mortality rates
In addition, metallic or polymeric nonabsorbable struts prevent vessel lumen remodeling and dilation

Embodiment approach

[0132]In one stent embodiment, the stent includes a rollable polymer support tube that can be inserted through a balloon delivery system for vascular implantation. However, the flexible plasticity of the support tube stent can cause the crimped configuration on the carrier system for blood vessel insertion or delivery to relax. Therefore, the crimped stent is prone to "displacement", moving away from the destination of the airbag carrier or becoming completely loose. Therefore, in a preferred embodiment, a protective mechanism is provided for such a polymer device, such as a support tube, to protect against the stent being placed or installed on the delivery system and when the crimping device is deployed into a tubular organ. Unexpected opening occurred during the desired position. This article discloses various protection mechanisms that can be used with medical devices. The protection mechanism can be designed to be adjacent to the circumferential far and proximal ring struts (...
