Patent application number | Description | Published |
20080319531 | FLEXIBLE AND EXPANDABLE STENT - In one embodiment of the invention, a stent may be provided comprising a first undulating band having alternating peaks and troughs, a second undulating band having alternating peaks and troughs, a first substantially longitudinal connector extending between the first and second undulating bands and a second very short connector extending between the first and second undulating bands, the first connector substantially longer than the second very short connector. | 12-25-2008 |
20100137974 | Stent with Graduated Stiffness - Disclosed herein is a stent having a generally tubular stent body with a first end region, a second end region, and a third region therebetween. The stent has a plurality of circumferential serpentine bands and a plurality of connector columns. Each connector column is located between two immediately adjacent serpentine bands, with each connector column having at least one connector. Connectors are connected at one end to one serpentine band and at the other end to an immediately adjacent serpentine band. The connectors of the first and second end regions have a first length which is substantially parallel to the longitudinal axis, and the connectors of the third region have a length greater than the first length and form an oblique angle relative to the longitudinal axis. | 06-03-2010 |
20120185035 | FLEXIBLE AND EXPANDABLE STENT - In one embodiment of the invention, a stent may be provided comprising a first undulating band having alternating peaks and troughs, a second undulating band having alternating peaks and troughs, a first substantially longitudinal connector extending between the first and second undulating bands and a second very short connector extending between the first and second undulating bands, the first connector substantially longer than the second very short connector. | 07-19-2012 |
20130172983 | Stent with Anti-Migration Features - A stent has a first end region, a middle region, and a second end region, each region including a plurality of strut columns. The stent includes at least one barb. Each barb in an expanded state is at an angle relative to the outer surface of the stent. | 07-04-2013 |
20140243974 | IMPLANTABLE MEDICAL DEVICES FOR REDUCED TISSUE INFLAMMATION - Implantable medical devices and methods for making and using the same are disclosed. An example implantable medical device may include a stent having a first configuration and a second expanded configuration. The stent may define a plurality of nodes. The stent may have a cover member disposed adjacent the nodes. The cover member may be configured to cover at least some of the nodes when the stent is in the expanded configuration. | 08-28-2014 |
20140277562 | Anti-Migration Tissue Anchoring System for a Fully Covered Stent - A prosthesis that includes a stent comprising a plurality of circumferential bands, a plurality of linking members, at least one anchor, or a prosthesis that includes a stent comprising at least one anchoring section comprising a first circumferential band, a second circumferential band, and at least one anchor. Optionally, the prosthesis further includes at least one cover. | 09-18-2014 |
20140379080 | Stent with Deflecting Connector - This disclosure is directed primarily to a stent for use in the trachea. The stent has a nominally deployed state, an axially extended state and an axially compressed state. The stent has a length. In the axially extended state, the length is at least 20% greater than in the nominally deployed state. | 12-25-2014 |
20150073529 | STENT WITH ANTI-MIGRATION CONNECTORS - An endoprosthesis, such as a stent, having anti-migration features. The endoprosthesis includes an expandable tubular framework including a plurality of strut rows and a plurality of connectors extending across interstices between adjacent strut rows and interconnecting adjacent strut rows. The strut rows have an outer diameter in an expanded state and the connectors extend radially outward beyond the outer diameter of the strut rows in the expanded state. The connectors are configured to engage a wall of a body lumen in the expanded state to inhibit migration of the endoprosthesis in the body lumen. The endoprosthesis may include a polymeric cover covering the strut rows and spanning the interstices between adjacent strut rows, while a space between the connectors and the strut rows to which the connectors are interconnected with is devoid of the polymeric cover to permit tissue ingrowth around the connectors. | 03-12-2015 |
