Publication number: 20240009369Abstract: An endovascular implant for forming a fistula includes a body including a wall forming a lumen having a distal opening and a proximal opening. An anchor is coupled to a distal end of the body adjacent the distal opening. The anchor may include a first anchor extending from a first side of a distal end of the body, and a second, separate anchor may extending from a second side of the distal end of the body. A retriever may be coupled to a proximal end of the body adjacent the proximal opening.Type: ApplicationFiled: September 16, 2021Publication date: January 11, 2024Inventors: Alexander W.

Publication number: 20220280244Abstract: In one aspect, a system for endovascular treatment of a blood vessel includes a control unit, an ultrasound device, an actuator, and a catheter having a treatment portion. The ultrasound device is communicatively coupled to the control unit. The ultrasound device includes an ultrasound probe having a subject contact surface. The actuator is coupled to the ultrasound probe and is operable to move the subject contact surface of the ultrasound prove relative to a treatment zone of a subject. The control unit is configured to determine a position of the treatment portion of the catheter as the catheter is advanced through the blood vessel, and move the subject contact surface of the ultrasound probe relative to the treatment zone of the subject with the actuator to follow the position of the catheter as the catheter is advanced through the blood vessel.Type: ApplicationFiled: May 31, 2019Publication date: September 8, 2022Applicant: TVA Medical, Inc.Inventors: Peng Zheng, Alexander W. Tessmer, Jeremy B. Cox, Andrzej J. Chanduszko, Michael Randall, Thomas Diffley Pate

Patent number: 11103339Abstract: A method of treating a patient includes providing an implantable vessel filter including a plurality of legs and center-post, inserting the filter into a delivery assembly, and deploying the filter at a desired location in a patient's body. One or more of the legs may have a hook at a distal end thereof and the center-post includes a grooved distal section to receive the hooks. The filter legs transition from a compressed configuration to an expanded configuration during deployment.Type: GrantFiled: September 17, 2018Date of Patent: August 31, 2021Assignee: C. R. BARD, INC.Inventor: Alexander W. Tessmer

Patent number: 10512531Abstract: A filter delivery device for implanting a vessel filter within a blood vessel of a patient's body. The filter delivery device includes a mechanism for preventing hooks and/or legs on a vessel filter from entangling with each other while the vessel filter is loaded within the delivery device. In one variation, the filter delivery device includes a delivery catheter with grooves at the distal end lumen opening. When a vessel filter with radially expanding legs is compressed and inserted into the distal end of the delivery catheter, the hooks on the distal end of the legs are received and separated by the corresponding grooves on the delivery catheter. In another variation, a pusher rod, with a receptacle for receiving the hooks, is positioned within a delivery catheter to prevent the entanglement of the hooks and/or legs of a filter loaded within the delivery catheter.Type: GrantFiled: June 26, 2017Date of Patent: December 24, 2019Assignee: C. R. BARD, INC.Inventors: Alexander W. Tessmer, David G. Spilka, David W. Rauch, Andrzej J. Chanduszko, Robert M. Carr, Jr.
