Patent number: 11937821Abstract: A power controller device and system allows verification, monitoring, and control of an arteriovenous (AV) fistula creation catheter which comprises a main housing having a power supply, an embedded electronic controller and a user interface display, and which is configured to allow connection to an intravascular catheter. When activated, the device verifies that a valid catheter is connected, downloads stored manufacturing calibration data from the catheter, and provides a user interface to allow initiation of AV fistula creation. Once creation of the AV fistula is initiated, the device provides closed loop control of the catheter heating element and provides a means of monitoring the catheter temperature and tip position to a prescribed parameter to automate the arteriovenous fistula creation procedure.Type: GrantFiled: May 16, 2018Date of Patent: March 26, 2024Assignee: AVENU MEDICAL, INC.Inventors: Gene B. Reu, Brad M. Kellerman, Mark A. Ritchart, David K. Wrolstad, David T. Aldridge, Justin K. Mann

Publication number: 20240016597Abstract: A catheter having opposed tissue contacting surfaces for creating an anastomosis between two blood vessels is utilized to facilitate a method for percutaneously placing a biologic graft at a procedural site. The method may comprise steps of advancing a biologic graft over a guidewire into a blood vessel at a biologic graft attachment site, advancing a catheter over the guidewire, and creating an anastomosis between the biologic graft and the blood vessel by activating the catheter to apply energy to a vessel wall of the blood vessel and to a wall of the biologic graft.Type: ApplicationFiled: September 27, 2023Publication date: January 18, 2024Inventors: Jeffrey E.

Patent number: 11786299Abstract: A catheter and tissue cutting system percutaneously permits the creation of an anastomosis between a first and second anatomical structure, such as a vein and an artery. The system comprises a catheter having a main body with a lumen and tapered distal tip, configured to be moved distally into the first anatomical structure over a primary guidewire. A cutting electrode is nested in the main body, with a lumen which tracks over a secondary guidewire, and is insertable into the secondary anatomical structure. An energy supply is operative to energize the cutting electrode in order to cut a tissue wall defining the first anatomical structure.Type: GrantFiled: August 31, 2020Date of Patent: October 17, 2023Inventors: Brad M. Kellerman, Justin K. Mann

Patent number: 11083460Abstract: A method of percutaneously creating a fistula includes inserting percutaneously a medical instrument to a target location having a first blood vessel and a second blood vessel. A fastener is then deployed via the medical instrument to the target location. The fastener is in a first configuration before the deploying and a second configuration after the deploying. The fastener limits relative movement between the first blood vessel and the second blood vessel when in the second configuration. An anastomosis between the first blood vessel and the second blood vessel is percutaneously produced.Type: GrantFiled: August 2, 2019Date of Patent: August 10, 2021Assignee: Avenu Medical, Inc.Inventors: Mark A.

Patent number: 8871136Abstract: Apparatuses and methods for joining one or more tubing sections together to form a tubular catheter device, for shaping one or more tubular sections of a catheter device, and/or for fusing elements (e.g., a radiopaque marker) onto a portion of the catheter. Each section of the catheter is typically fabricated independently from the other sections. Subsequently, the separate sections are fused together to form the catheter. The methods described herein allow the various sections of the catheter to be fitted together for fabrication without the use of heat-shrink tubing. The fitted parts are clamped in a die or mold at a temperature at or near room temperature; the die is then rapidly heated to fuse the parts, rapidly cooled back down to a temperature at or about room temperature, and removed from the die.Type: GrantFiled: March 8, 2013Date of Patent: October 28, 2014Assignee: Abbott Cardiovascular Systems, Inc.Inventors: David K.
