Patent number: 10736762Abstract: A delivery device according to principles described herein includes a catheter having three concentric shafts including an inner core, an outer sheath over the inner core and an outer support shaft at least partially extending over the inner core and the outer sheath. A timing belt having a plurality of belt teeth on a surface of the timing belt is coupled to an outer sheath over a medical device or stent on the inner core such that movement of the timing belt link causes movement of the outer sheath from its position over the medical device or stent. The delivery device is actuated by rotation of a thumbwheel a thumbwheel coupled to a barrel having a plurality of teeth such that rotation of the thumbwheel causes movement of the barrel such that the barrel teeth engage the belt teeth to cause movement of the timing belt causing movement of the outer sheath.Type: GrantFiled: October 11, 2019Date of Patent: August 11, 2020Assignee: Vesper Medical, Inc.Inventors: Michael A.

Publication number: 20200069448Abstract: Implantable stents that include strips that are each comprised of main struts connected by first connectors, and adjacent strips are connected by second connectors. The strut connectors have a structure, including areas of expanded or reduced width or thickness, to account for venous applications. When used for venous applications, the stents convey benefit from configurations that improve flexibility (due to the greater elasticity of venous applications) while maintaining enough stiffness to resist pressure on the venous structure in selected areas (such as for the May-Thurner syndrome). The stents include particular structural characteristics that are particularly advantageous for (although not limited to) venous applications.Type: ApplicationFiled: November 1, 2019Publication date: March 5, 2020Inventors: Michael A.
