Patent number: 9572652Abstract: Modular endograft devices and associated systems and methods are disclosed herein. In several embodiments, an endograft system can include a first endograft device and a second endograft device that each include an integrated frame, a cover and a lumen within the cover. Each endograft device further includes a superior portion and an inferior portion. The superior portion can have a convexly curved outer wall and a septal wall. The first and second endograft devices can be configured to extend into a low-profile configuration with a first cross-sectional dimension and a first length and self-expand into an expanded configuration with a second cross-sectional dimension greater than the first cross-sectional dimension and a second length less than the first length. In the expanded configuration, the septal walls can press against each other and form a septum between the lumens of the first and second endograft devices.Type: GrantFiled: December 1, 2010Date of Patent: February 21, 2017Assignee: Altura Medical, Inc.Inventors: Andrew H. Cragg, Stephen Sosnowski, Isa Rizk, John Fulkerson, John Logan

Publication number: 20100286722Abstract: A temporary vascular filter system comprising a catheter and an elongate filter slideably carried near the distal end of said catheter. The vascular filter system can be inserted into a vessel percutaneously with the filter in a narrow-diameter “closed position” and expanded into a large diameter “open position” at the desired intravascular site. After deployment, the proximal portion of the catheter can be secured to the patient at the insertion site. While deployed, the filter component is capable of sliding along a portion of the catheter throughout a range of motion. The filter may have two filter meshes, which may have different degrees of porosity. The temporary vascular filter system can be left in the patient for hours or days and then collapsed into a withdrawal tube for removal from the patient.Type: ApplicationFiled: May 11, 2009Publication date: November 11, 2010Applicant: Intersect Partners, LLCInventors: Isa Rizk, John Fulkerson, Andrew H.

Patent number: 6344044Abstract: An apparatus and method for intraluminal delivery and deployment of an expandable prosthesis at a site within a body canal is provided. The apparatus comprises an elongated sleeve and an outer shaft disposed within the elongated sleeve and movable relative to the sleeve. A securing member is disposed on a distal area of the outer shaft. The expandable prosthesis is housed within a distal area of the elongated sleeve, and a distal area of the prosthesis is secured to the outer shaft by the securing member. The stent is deployed by displacing the sleeve in a proximal direction relative to the outer shaft to expose the stent and by releasing the stent from the securing member. If necessary, the stent can be repositioned prior to releasing the stent from the securing member.Type: GrantFiled: February 11, 2000Date of Patent: February 5, 2002Assignee: Edwards Lifesciences Corp.Inventors: John Fulkerson, Rogelio Pepa, Isa Rizk, Karim Mouneimne
