Patent number: 10987118Abstract: As may be implemented with various aspects of the present disclosure, a mesh structure is coupled to inner and outer frames that operate with struts to apply pressure to the mesh. Such an approach may involve sealing the mesh around an opening, such as around one or more artery openings along an interior wall of vascular tissue (e.g., in an aortic arch). Accordingly, blood flow can be filtered in a manner that is useful for capturing particulates such as those resulting from surgical operations. In various implementations, the mesh, struts and frames are deployed using a catheter and shaft coupled to the frames. Such an approach can be implemented to apply a spring force from the shaft and through the frames for sealing the mesh.Type: GrantFiled: September 4, 2018Date of Patent: April 27, 2021Assignee: Transverse Medical Inc.Inventors: Abdolrahim Zandi, Sepehr Fariabi, J. Eric Goslau, David S. Nevrla, Brad Lees

Patent number: 10709872Abstract: Embodiments of the invention are directed towards a rapid exchange catheter configured for insertion into a subintimal space and crossing an occlusion in a subintimal space. The catheter includes a proximal end, a distal end, a first lumen configured to receive a first wire, the first lumen extending longitudinally through a least a lateral port of the catheter, and a second lumen having at least a portion distal of the lateral port and extending through at least the distal end of the catheter. The catheter also includes an exchange port, arranged on an exterior portion of the catheter configured to receive a second wire and second rapid exchange port in communication with the second lumen. Moreover, other embodiments of the invention are directed towards methods for using the rapid exchange catheter to cross an obstruction in a vessel, e.g., a total or partial occlusion, in a subintimal space.Type: GrantFiled: October 4, 2017Date of Patent: July 14, 2020Assignee: THE SPECTRANETICS CORPORATIONInventors: Jeffery B. Alvarez, Christine Godleski, Wade A. Bowe, Rob Carver, Paola A. Dwelle, Jeff Lindstrom, David S. Nevrla, Shahriar Matin, Matthew M. Magee
