Publication number: 20230104099Abstract: A self-expanding braided stent includes at least a distal radial expansion ring added to a distal end of the stent body to increase a radial expansion force of the self-expanding braided stent in deployment of the stent, and to facilitate advancement of the stent through a delivery sheath by a core advancement wire. A proximal radial expansion ring is optionally added to a proximal end of the stent body to allow the stent to be recaptured following partial deployment by retraction of the core advancement wire, prior to full deployment of a proximal portion of the stent body.Type: ApplicationFiled: November 30, 2022Publication date: April 6, 2023Applicant: DePuy Synthes Products, Inc.Inventors: Robert SLAZAS, Ramin TEHRANI

Publication number: 20190125557Abstract: A braided stent system includes a stent body having a lumen formed by a plurality of braided members with interstices formed therebetween and a first expansion ring connected to the lumen of the stent body. The first expansion ring may include a frame defined by a plurality of interconnected support assemblies that are selectively positioned to impart an outwardly expanding radial force to the stent body, each support assembly can include a plurality of legs joined at a first intersection and connected to one of the other interconnected support assemblies at a second intersection opposite the first intersection. Each support assembly can include a claw portion mechanically connected to one or more of the interstices of the stent body so that the frame imparts an outward radial expansion force of the stent to facilitate use and delivery of the stent.Type: ApplicationFiled: December 27, 2018Publication date: May 2, 2019Applicant: DePuy Synthes Products, Inc.Inventors: Juan LORENZO, Robert SLAZAS, Ramin TEHRANI, Pedro PEDROSO
