Publication number: 20230093376Abstract: The invention relates to a medical device and a method of using it. The device is a stent which can be percutaneously deliverable with (or on) an endovascular catheter or via other surgical or other techniques and then expanded. The stent is configured to have a central portion defined by “open” cells and at least two end portions, defined by “closed” cells, spaced apart and directly connected to the distal and proximal ends of the central portion of the stent. The stent may also optionally have a covering or a lattice with openings.Type: ApplicationFiled: November 23, 2022Publication date: March 23, 2023Inventors: Joseph R. Armstrong, Edward H. Cully, Michael W. Franklin, Mark Y. Hansen, Brandon A. Lurie, Craig R. McMurray, William D. Montgomery, Wendy J. Terry, Eric M. Tittelbaugh

Publication number: 20220296353Abstract: Various aspects of the instant disclosure relate to flow devices including filters and occluders for modifying flow in body conduits such as blood vessels. In some examples, such devices include a support structure and a flow media coupled to the support structure. The medical device generally further includes one or more capture features. In some examples, the capture features are coupled to the support structure at one or more of the proximal and distal ends of the support structure. In various examples, the capture features facilitate retrograde and antegrade deployment of the medical device and retrograde and antegrade capture of the medical device.Type: ApplicationFiled: June 8, 2022Publication date: September 22, 2022Inventors: William D. Montgomery, Edward E. Shaw

Publication number: 20220296354Abstract: Various aspects of the present disclosure are directed toward an embolic filter system. The embolic filter system generally includes a filter and an elongated element. In some examples, the elongate element extends to a position distal to a proximal end of the filter and operates to protect against medical devices entangling with the filter. In some examples, the elongate element is soft and compliant and operates with a hemostatic seal to provide for a hemostatic seal within a lumen of the elongate element while maintaining the lumen as a working lumen through which medical devices can be passed.Type: ApplicationFiled: April 8, 2022Publication date: September 22, 2022Inventors: William D. Montgomery, Edward E. Shaw

Publication number: 20210068996Abstract: The invention relates to medical devices and methods of using them. The devices are prostheses which can be percutaneously deliverable with (or on) an endovascular catheter or via other surgical or other techniques and then expanded. The prostheses are configured to have a lattice resistant to dilation and creep, which is defined by a plurality of openings. The prosthesis may also optionally have a stent disposed proximal to the lattice. In exemplary embodiments, the fluoropolymer is expanded polytetrafluoroethylene. The composite materials exhibit high elongation while substantially retaining the strength properties of the fluoropolymer membrane. In at least one embodiment, the lattice is made of a composite material that includes a least one fluoropolymer membrane including serpentine fibrils and an elastomer. A lattice including a generally tubular member formed of a composite material including a least one fluoropolymer membrane containing serpentine fibrils and an elastomer is also provided.Type: ApplicationFiled: November 16, 2020Publication date: March 11, 2021Inventors: Joseph R.
