Publication number: 20220249263Abstract: A system for deploying a stent-graft from the femoral artery into the femoral vein and back into the femoral artery in order to bypass a femoral occlusion comprises a penetration catheter and a guidewire capture and stabilization catheter. The penetration catheter may be advanced contralaterally to a location above the occlusion and the capture and stabilization catheter may be introduced upwardly through the femoral vein. The penetration tool on the penetration catheter is used in multiple steps to deploy guidewires which are then used to deploy the stent-graft in the desired location.Type: ApplicationFiled: March 4, 2019Publication date: August 11, 2022Applicant: PQ Bypass, Inc.Inventors: Richard R. Heuser, James D. Joye, Kumar Ganesan Jambunathan, Eugene E. Reis, Richard A. Lotti

Patent number: 10182902Abstract: Embodiments herein provide differential dilation stents for use in percutaneous interventions, such as transluminal bypass procedures. In some embodiments, the stents may be used in the process of creating an arteriovenous (AV) fistula during a percutaneous bypass procedure, and such stents may have two or more specialized regions that are configured to adopt a predetermined diameter, shape, and/or tensile strength upon insertion in order to suit the needs of the vessel or procedure. The disclosed stents may be used for creating and/or maintaining an arterial/venous fistula for bypass of an occlusion in a cardiac artery using a cardiac vein, or the femoral artery, for example using the tibial or popliteal vein.Type: GrantFiled: February 25, 2016Date of Patent: January 22, 2019Assignee: PQ Bypass, Inc.Inventors: Richard R. Heuser, Kumar Jambunathan, Richard A. Lotti

Publication number: 20190015631Abstract: An infusion catheter assembly has the ability to infinitely titrate the length of a porous fluid distribution section in situ. The infusion catheter assembly thereby provides a length of infusion that can be infinitely varied over a prescribed range, to control the effective infusion length and the rate of infusion. Using the infusion catheter assembly, a physician has the capability to treat only the length of the vessel desired, thereby preventing excessive drug/patient exposures. The porous fluid distribution section can include an array of spaced apart apertures that vary in size and/or density along the length of the porous fluid distribution section, such that the flow rate remains essentially constant for a given inlet pressure independent of the effective infusion length.Type: ApplicationFiled: July 25, 2018Publication date: January 17, 2019Inventors: Anthony J. Comerota, Thomas J. Fogarty, Jonathan M. Olson, Richard A. Lotti

Patent number: 10092732Abstract: An example of recovery catheter assembly comprises an actuator element and a mechanically radially expandable and contractible recovery device operably connected to the actuator element. The recovery device has proximal and distal blocking portions and a central portion therebetween. The recovery device is at least partially placeable in a first, radially collapsed configuration and in a second, radially expanded configuration by manipulation of the actuator element. When in the second, radially expanded configuration, the proximal and distal blocking portions have radial dimensions greater than the radial dimension of the central portion thereby at least partially defining a collection chamber at the central portion.Type: GrantFiled: January 14, 2016Date of Patent: October 9, 2018Assignee: Nfusion Vascular Systems, LLCInventors: Richard Eustis Fulton, III, Richard Lotti

Publication number: 20180028741Abstract: A recovery device assembly comprises an actuator element and a mechanically radially expandable and contractible recovery device operably connected to the actuator element is provided. The recovery device has proximal and distal toroidal balloon blocking elements and a central portion between the blocking elements. The recovery device is at least partially placeable in a first, radially collapsed configuration and in a second, radially expanded configuration by manipulation of the actuator element. When in the second, radially expanded configuration, the proximal and distal blocking elements have radial dimensions greater than the radial dimension of the central portion thereby at least partially defining a collection chamber at the central portion. Also provided are methods of isolating an organ and recovering blood from an organ that use the recovery device assembly provided.Type: ApplicationFiled: October 9, 2017Publication date: February 1, 2018Applicant: NFUSION VASCULAR SYSTEMS, LLCInventors: Richard Eustis Fulton, III, Richard Lotti
