Patent number: 10598093Abstract: A power generation system includes a turbine having an outlet. A high temperature recuperator has an inlet and is connected to the turbine outlet. A low temperature recuperator is connected to the high temperature recuperator. Each of the high and low temperature recuperators include a plurality of matrix panels interconnected together that define hot fluid channels and cold fluid channels arranged adjacent to each other in a counterflow and stair-step configuration. A compressor is connected to the low temperature recuperator and turbine.Type: GrantFiled: March 31, 2016Date of Patent: March 24, 2020Assignee: UNIVERSITY OF CENTRAL FLORIDA RESEARCH FOUNDATION, INC.Inventors: Jayanta S. Kapat, Jihua Gou, Narasimha Nagaiah, Joshua Schmitt

Patent number: 10335265Abstract: A stent-graft has a closed web end configuration in which endmost stent crowns do not extend beyond an end or edge of a tubular graft. In order to couple the stent-graft to tip capture fingers or prongs of a delivery system, the stent-graft includes a ring woven between the endmost crowns of an end stent. When end stent is in a compressed delivery configuration, sections of the ring between adjacent endmost crowns form attachment loops that longitudinally extend beyond the end of the tubular graft for engaging the tip capture fingers of a delivery system. When the end stent is in an expanded fully deployed configuration, the attachment loops retract back to the stent so that the ring is a circular band having a diameter substantially equal to the expanded diameter of the stent.Type: GrantFiled: October 8, 2014Date of Patent: July 2, 2019Assignee: Medtronic Vascular, Inc.Inventors: Jeremy Kinkade, Mark Stiger, Brandon Woll, Joshua Schmitt

Patent number: 9095463Abstract: Stent-graft delivery systems having a tip capture mechanism with a plurality of elongated cables that allow for gradual deployment and repositioning of a stent-graft prosthesis. The tip capture mechanism includes a guiding assembly, a distal tip assembly, and a plurality of cables. In a first relative position, the distal tip assembly extends the guiding assembly to temporarily constrain the distal ends of the cables and an intermediate portion of each cable constrains an endmost crown of the prosthesis. In this first relative position, tension on the cables may be selectively adjusted to allow for both gradual continuous radial expansion and contraction of the endmost crowns of the stent-graft prosthesis. In a second relative position, the distal tip assembly does not extend over the guiding assembly and thus does not constrain the distal ends of the cables, and thereby the cables do not constrain the endmost crowns.Type: GrantFiled: February 21, 2013Date of Patent: August 4, 2015Assignee: Medtronic Vascular, Inc.Inventors: Jeffery Argentine, Joshua Schmitt, Mark Stiger, Brandon Woll

Patent number: 8850676Abstract: A removable guidewire funnel tool aids in backloading a catheter onto a guidewire. The guidewire funnel tool includes a pliable loading coupler having a lumen therethrough. The lumen has a tapered distal section that serves to receive a guidewire and a tapered proximal section that receives and couples with a correspondingly tapered distal tip of the catheter. The guidewire funnel tool has a longitudinal slot or area of weakness along the entire length of the loading coupler and a grip tab to enable easy removal of the guidewire funnel tool after the guidewire lumen of the catheter is loading with the guidewire.Type: GrantFiled: February 23, 2011Date of Patent: October 7, 2014Assignee: Medtronic Vascular, Inc.Inventor: Joshua Schmitt
