Patent number: 11937822Abstract: A device for creating a fistula between blood vessels operates in conjunction with a guidewire to locate and position itself so that it straddles both vessels and is able to draw them together. A fixing agent is released either from within the device or from an external needle, or both, into the procedural site. The fixing agent functions to hold the relative position of the two vessels, to seal the surrounding tissue so that any leaks that do occur don't spread into the tissue to create a hematoma, and to limit expansion of the fistula. After the vessels are in close proximity to each other and the fixing agent is applied, the device of the invention employs a cutting mechanism which opens a portal between the two vessels.Type: GrantFiled: July 6, 2020Date of Patent: March 26, 2024Assignee: AVENU MEDICAL, INC.Inventors: Seth Arnold Foerster, Brad Mathew Kellerman, Mark Andrew Ritchart, Justin Kellogg Mann

Patent number: 11918224Abstract: A catheter system for creating an arteriovenous (AV) fistula includes a proximal base having a distal end surface. A distal tip is connected to the proximal base and is movable relative to the proximal base. The distal tip has a proximal end surface. The distal end surface and the proximal end surface are adapted to contact opposing sides of a tissue portion to create the fistula. A peripheral edge defines the distal end surface of the proximal base.

Publication number: 20140018828Abstract: A method for repairing separated tissues utilises a tissue tensioner including a locking member, a band, a frame, and a restraining member. One end of the band is attached to a first end of the frame. Tension is applied to the band so that it moves freely between spaced engaging surfaces on the locking bar and a second end of the frame, while a restraining member restrains the locking member to a non-engaging position. Application of a predetermined level of tension on the band causes the restraining member to move to a non-restraining orientation, thereby in turn causing the locking member to move so that its engaging surfaces engage the engaging surfaces of the frame, clamping the band. An alarm is triggered to notify a practitioner that the predetermined level of tension has been achieved and that the restraining member has thus moved to the non-restraining orientation.Type: ApplicationFiled: May 21, 2012Publication date: January 16, 2014Applicant: DALLEN MEDICAL, INC.Inventors: Seth Arnold Foerster, David Trottingwolf Aldridge
