Publication number: 20220175364Abstract: A septal closure and port device for implantation in the atrial septum of a patient's heart comprises an expandable frame can comprise a central portion defining a lumen, and first and second opposing end portions. The frame is configured to expand and contract between a compressed, tubular configuration for delivery through the patient's vasculature and an expanded configuration in which the first and second end portions extend radially outwardly from the opposite ends of the central portion. The device can further comprise a valve member supported on the frame and positioned to block at least the flow of blood from the left atrium to the right atrium through the lumen of the frame. The valve member is configured to permit a medical instrument inserted through the lumen and into the left atrium, such as for performing a subsequent medical procedure in the left side of the heart.Type: ApplicationFiled: February 22, 2022Publication date: June 9, 2022Inventors: Stanton J.

Publication number: 20220176087Abstract: Devices and methods of treating fluid retention caused by congestive heart failure or other conditions resulting in edema, lymphoedema, or significant fluid retention (e.g., deep vein thrombosis, cellulitis, venous stasis insufficiency, or damage to the lymphatic network) are described. Specifically, a treatment device is used to create a passage or cannula between the lymphatic system (or other area of the body) and an external drainage device. This device can be only temporarily located in the patient or can be implanted within the patient for longer periods of time. The physician can safely and reliably remove excess fluid from the body via the device and optionally inject other treatment agents.Type: ApplicationFiled: February 24, 2022Publication date: June 9, 2022Applicant: NXT Biomedical, LLCInventors: Robert S.

Patent number: 11344411Abstract: The present invention relates to devices and methods for improving the function of a defective heart valve, and particularly for reducing regurgitation through an atrioventricular heart valveāi.e., the mitral valve and the tricuspid valve. For a tricuspid repair, the device includes an anchor deployed in the tissue of the right ventricle, in an orifice opening to the right atrium, or anchored to the tricuspid valve. A flexible anchor rail connects to the anchor and a coaptation element on a catheter rides over the anchor rail. The catheter attaches to the proximal end of the coaptation element, and a locking mechanism fixes the position of the coaptation element relative to the anchor rail. Finally, there is a proximal anchoring feature to fix the proximal end of the coaptation catheter subcutaneously adjacent the subclavian vein. The coaptation element includes an inert covering and helps reduce regurgitation through contact with the valve leaflets.Type: GrantFiled: April 19, 2019Date of Patent: May 31, 2022Assignee: Edwards Lifesciences CorporationInventors: Stanton J.

Publication number: 20220142806Abstract: Renal and urine collection system interventions are provided that improve kidney function by manipulating pressures and/or infusing therapeutic agents in the renal pelvis of the kidney or kidneys. Setting a vacuum and/or infusing therapeutic agents in the renal pelvis results in increased glomerular filtration rate, general solute clearance, and free water excretion via the kidney through the urinary tract and is useful for treatment of CHF, ADHF, AKI, CKD, and many other conditions characterized by fluid overload by reducing fluid buildup. The fluid drawn from the renal pelvis or pelvises is delivered to an external or implanted reservoir or to the bladder using flow manipulation mechanism such as one-way valves, occlusion balloons, multi-lumen catheters, and other mechanisms. Pumps are provided for use in establishing the vacuum pressures that are either manual or motorized.Type: ApplicationFiled: May 18, 2020Publication date: May 12, 2022Applicant: NXT Biomedical, LLCInventors: Joseph Passman, Abubaker Khalifa, Stanton J.

Patent number: 11284998Abstract: A two-stage or component-based valve prosthesis that can be quickly and easily implanted during a surgical procedure is provided. The prosthetic valve comprises a support structure that is deployed at a treatment site. The prosthetic valve further comprises a valve member configured to be quickly connected to the support structure. The support structure may take the form of a stent that is expanded at the site of a native valve. If desired, the native leaflets may remain and the stent may be used to hold the native valve open. In this case, the stent may be balloon expandable and configured to resist the powerful recoil force of the native leaflets. The support structure is provided with a coupling means for attachment to the valve member, thereby fixing the position of the valve member in the body. The valve member may be a non-expandable type, or may be expandable from a compressed state to an expanded state.Type: GrantFiled: October 28, 2019Date of Patent: March 29, 2022Assignee: Edwards Lifesciences CorporationInventors: Stanton J.
