A recently granted patent (Publication Number: US11925570B2) discloses a novel stent design featuring a radially expandable scaffold with fixation members and biodegradable materials. The stent includes fixation members that transition from a constrained to an extended configuration, engaging target tissue sites. The biodegradable material degrades post-expansion, allowing the fixation members to engage the tissue while maintaining scaffold integrity. The design aims to enhance stent performance and tissue interaction post-implantation.

Furthermore, the patent details variations in the stent design, including multiple fixation members with projections for tissue engagement and the use of biodegradable films or materials that dissolve upon contact with enzymes. These features ensure precise tissue anchoring and controlled degradation, improving the overall effectiveness of the stent. The innovative approach of combining fixation members, biodegradable materials, and scaffold design showcases advancements in stent technology for better patient outcomes and long-term efficacy.
