Publication number: 20240130734Abstract: The present technology includes systems and methods for invasively adjusting implantable devices for selectively controlling fluid flow between a first body region and a second body region of a patient. For example, in many of the embodiments described herein, a catheter can be used to mechanically and/or electrically engage an implanted medical device. Once the catheter engages the medical device, the catheter can (i) increase a dimension associated with the medical device, such as through mechanical expansion forces, and/or (ii) decrease a dimension associated with the medical device, such as by heating a shape memory component of the medical device above a phase transition temperature.Type: ApplicationFiled: August 23, 2023Publication date: April 25, 2024Inventors: Miles Alexander, Peter Andriola, Brian Fahey, William Jason Fox, Anthony Pantages, Scott Robertson, Jace Valls

Publication number: 20240000404Abstract: The present technology relates to interatrial shunting systems and methods. In some embodiments, the present technology includes a method for monitoring a shunting element implanted in a patient and having a lumen fluidly coupling cavities of the patient's heart. The method can comprise obtaining first and second radiographic images of at least two radiopaque elements associated with the lumen of the shunting element. A spatial relationship between the radiopaque elements varies according to a size of the lumen. The first radiographic image can be taken from a first viewing angle and the second radiographic image can be taken from a second viewing angle generally orthonormal to the first viewing an The method also includes determining the size of the lumen based, at least in part. on locations of the radiopaque elements in the first and second radiographic images.Type: ApplicationFiled: April 23, 2021Publication date: January 4, 2024Inventors: Scott Robertson, Brian Fahey, Miles Alexander, Peter Andriola, William Jason Fox, Anthony Pantages

Patent number: 9579091Abstract: A closure system and methods of use are provided for use in sealing an opening in a body tissue, such as a vascular puncture site. A method of closing the opening in the body tissue can be performed with the closure system having a closure clip. The method can include positioning the closure clip in a first closure clip position adjacent to the opening in the body tissue such that a plurality of spikes of the closure clip are inserted into the tissue at a location outward from a central axis of the opening. Subsequently, the closure clip can be positioned in a second closure clip position such that the plurality of spikes are pulled inward toward the central axis of the opening so as to pull the tissue between the opening and each of the spikes together and close the opening.Type: GrantFiled: April 3, 2006Date of Patent: February 28, 2017Assignee: INTEGRATED VASCULAR SYSTEMS, INC.Inventors: Richard S.

Patent number: 8926656Abstract: An apparatus for delivering a closure element into an opening formed in a blood vessel or other body lumen and methods for manufacturing and using same. The apparatus is configured to retain the closure element such that the closure element is disposed substantially within the apparatus. The apparatus also can engage, and position the closure element substantially adjacent to, the blood vessel wall adjacent to the opening. During deployment of the closure element, the apparatus expands the closure element beyond a natural cross-section of the closure element such that the closure element, when deployed, is configured to engage a significant amount of the blood vessel wall and/or tissue. Engaging the blood vessel wall and/or tissue, the closure element is further configured to return to the natural cross-section, thereby drawing the engaged blood vessel wall and/or tissue substantially closed and/or sealed, such that hemostasis within the opening is enhanced.Type: GrantFiled: January 10, 2011Date of Patent: January 6, 2015Assignee: Integated Vascular Systems, Inc.Inventors: Thomas J Palermo, William M Belef, Michael T Carley, Richard S Ginn, Ronald J Jabba, Anthony Pantages
