Patent number: 12239533Abstract: Delivery systems, methods and associated devices to facilitate delivery and deployment of a heart implant. Such delivery systems and methods of delivery include use of a pair of magnetic catheters, including an anchor delivery catheter carrying an anchor, which can be stacked with or can be axially offset from the magnetic head. Such systems further include use of a puncturing guidewire advanceable through the magnetic head of the anchor delivery catheter to establish access to a chamber of a heart and which is attached to a bridging element such that continued advancement of the guidewire draws a bridging element attached to the first anchor across the chamber of the heart while the bridging element remains covered by the magnetically coupled catheters. Methods and devices herein also allow for cutting and removal of a bridge element of a deployed heart implant.Type: GrantFiled: December 7, 2021Date of Patent: March 4, 2025Assignee: MVRx, Inc.Inventors: David A. Rahdert, Richard T. Childs, David R. Tholfsen, Patrick P. Wu

Publication number: 20240268688Abstract: The present technology is generally directed to medical systems having sensors and diaphragms. The sensor device can include a body having a diaphragm. The diaphragm can be formed, for example, by applying a force to the body to create an impression or pattern that corresponds to the diaphragm. The sensor device can be positioned at least partially within a body cavity, and the diaphragm can be configured to flex or bend in response to one or more physiological parameters in the body cavity. In some embodiments, the sensor device can include one or more sensor measurement components configured to measure the one or more physiological parameters based on the flexing or bending of the diaphragm.Type: ApplicationFiled: June 17, 2022Publication date: August 15, 2024Inventors: Brian Fahey, Peter Andriola, Scott Robertson, Craig Myers, Isa Mulvihill, Ian Baranowski, David Rahdert, Shahn Sage

Publication number: 20240033085Abstract: A method for traversing an anatomical vessel wall of a subject is provided. The invention allows the crossing of a wire from one anatomical lumen, such as an artery, vein, esophagus, intestine or airway, through tissue, into another anatomical lumen, or cavity, or into a solid mass of tissue. In some aspects, the invention allows the crossing of a wire from the greater cardiac vein (GCV) into the left atrium without relying on another device in the left atrium to facilitate the crossing.Type: ApplicationFiled: December 7, 2021Publication date: February 1, 2024Inventors: Patrick P. Wu, David A. Rahdert, Richard T. Childs, David R. Tholfsen

Publication number: 20240024107Abstract: Anchors for securing an implant within a body organ and/or reshaping a body organ are provided herein. Anchors are configured for deployment in a body lumen or vasculature of the patient that are curved or conformable to accommodate anatomy of the patient. Such anchors can include deformable or collapsible structures upon tensioning of a bridging element in a lateral direction, or segmented tubes that can be adjusted by tightening of one or more tethers extending therethrough. Such anchors can be used as a posterior anchor in a blood vessel in implant systems having a tensioned bridging element extending between the posterior anchor and an anterior anchor deployed at another location within or along the body organ. Methods of deploying such anchors and use of multiple anchors or multiple bridging elements to a single anchor are also provided.Type: ApplicationFiled: September 28, 2023Publication date: January 25, 2024Inventors: Timothy R.

Patent number: 9861475Abstract: Devices, systems, and methods employ an implant that is sized and configured to attach to the annulus of a dysfunctional heart valve annulus. In use, the implant extends across the major axis of the annulus above and/or along the valve annulus. The implant reshapes the major axis dimension and/or other surrounding anatomic structures. The implant restores to the heart valve annulus and leaflets a more functional anatomic shape and tension. The more functional anatomic shape and tension are conducive to coaptation of the leaflets during systole, which, in turn, reduces regurgitation. The implant improves function to the valve, without surgically cinching, resecting, and/or fixing in position large portions of a dilated annulus, or without the surgical fixation of ring-like structures.Type: GrantFiled: August 12, 2009Date of Patent: January 9, 2018Assignee: MVRX INC.Inventors: Timothy R.
