  • Patent number: 12636148
    Abstract: The disclosure relates to heart valve prostheses with the reduced need of pacemaker implantation and/or improved means for positioning the replacement heart valve. A heart valve prosthesis is provided with a stent and at least one locator. The locator has an adapted design for positioning within a cusp of the native aortic valve for implantation at the native heart valve site. Placement of the locators within the cusps preferably prevents movement from the native heart valve site post-implantation, including proximal movement of the prosthesis into the left ventricle.

  • Publication number: 20260060617
    Abstract: The present technology relates to intracardiac pressure monitoring devices, and associated systems and methods. In some embodiments, the present technology includes a device for monitoring pressure within a patient's heart. The device can include a pressure sensor configured to reside within a first chamber of a heart of a patient, and a pressure transmission element configured to extend from the first chamber through a septal wall to a second chamber of the heart of the patient. When the device is implanted in the patient's heart, the pressure transmission element is configured to transmit pressure from the second chamber to the pressure sensor residing within the first chamber.

  • Patent number: 12551207
    Abstract: A heart valve prosthesis for replacing a native atrioventricular valve of the heart. The prosthesis includes a housing component that is configured to be radially expandable and compressible between a radially compressed state and a radially expanded state to engage structure of the native atrioventricular valve to fix the housing component relative to the native atrioventricular valve. The housing component includes a housing body and an annular sealing element connected to an atrial end of the housing body. The annular sealing element is made of polyester and is reinforced with wire. A valve component is configured to be radially expandable and compressible between a radially compressed state and a radially expanded state within the housing component.

  • Patent number: 12533500
    Abstract: The present technology is generally directed to interatrial shunting systems and associated devices and methods. For example, a system configured in accordance with embodiments of the present technology can include a shunting element implantable into a patient at or adjacent a septal wall. The shunting element can have a lumen that fluidly connects a left atrium and a right atrium of the patient to facilitate blood flow therebetween when the shunting element is implanted. In some embodiments, the system further includes a flow control element to selectively control blood flow between the left atrium and the right atrium.

  • Patent number: 12343255
    Abstract: The disclosure relates to heart have prostheses with the reduced need of pacemaker implantation and improved means for positioning the replacement heart valve. In one aspect of the present disclosure, the stent scaffold of the valve prosthesis includes axially extending locators. The locators may be positioned within the cusp of the native aortic valve. Placement of the locators within the cusps may prevent further proximal movement of the stent scaffold into the left ventricle. By adjusting the location of the proximal end of the locators with respect to the proximal end of the stent scaffold, infra-annular placement of the stent scaffold in the aortic annulus may be assured. In another aspect, means for visualizing the positioning of replacement heart valves at an implant site inside an individual's body is disclosed.

  • Publication number: 20250041566
    Abstract: Some embodiments are directed to a catheter system comprising an introducer having a main body, an introducer sheath projecting from the main body, and a first seal supported within the introducer and a catheter having a main body, an outer sheath projecting from the main body, a second seal supported within the catheter, and an inner core configured to be advanced axially through the main body, the second seal, and the outer sheath. The introducer can be configured to be selectively engageable with the catheter so that the catheter can be selectively and removably linked with the introducer in the axial direction. The catheter system can also be configured such that, when the introducer and the catheter are linked, the catheter can be rotatable relative to the introducer. The introducer can be configured to radially restrain an endoluminal prosthesis.

  • Publication number: 20240058591
    Abstract: An apparatus includes a hub including a front port, a side port, and a back port including a hemostasis valve. The apparatus further includes a sheath extending from the hemostasis valve through the front port and shaped to define one or more lateral openings within the hub. The sheath is configured for insertion into a blood vessel such that, subsequently to the insertion, a rate of flow of blood between the side port and the blood vessel via the lateral openings is controllable using an instrument passing through the hemostasis valve and into the sheath such that the instrument closes at least a portion of the lateral openings. Other embodiments are also described.

  • Patent number: 11786252
    Abstract: Methods for treatment of aneurysms using a sequential manifold console to deploy multiple filling structures are provided herein. In one aspect, aneurysms are treated by simultaneously filling two double-walled filling structure using a sequential manifold console to guide a user in the steps to be followed in the procedure and to reliably achieve a consistent and durable aneurysmal treatment using a curable medium. The structures may be delivered over balloon deployment mechanisms in order to shape and open tubular lumens therethrough. Pairs of filling structures delivered to the aneurysm from different access openings of a patient can be simultaneously prepared and pressurized from a single treatment console when treating abdominal aortic aneurysms using the described systems and methods.
