Tricuspid regurgitation treatment tool to be inserted into pulmonary artery
11576781 · 2023-02-14 · ·

A tricuspid regurgitation treatment tool to be inserted into the pulmonary artery is proposed. The tricuspid regurgitation treatment tool to be inserted into the pulmonary artery is used to verify whether the right ventricular dysfunction may occur when treating the tricuspid regurgitation by surgeries or other permanent treatments. A test insertion of the tricuspid regurgitation treatment tool to be inserted into the pulmonary artery is made to pass obliquely through the tricuspid valve of a patient, and after a certain time has elapsed, the tool is removed. The tricuspid regurgitation treatment tool to be inserted into the pulmonary artery includes: a blocking part blocking the tricuspid valve; and an insertion tube provided with a guidewire-guiding lumen formed therein to be movable along the guidewire.

Straddle mitral valve device and methods

A method for providing blood flow across a surface of a mitral stent-valve frame. A portion of the stent-valve frame is placed into the left atrium and into the left ventricle with a securement band located intermediate that is attached to either the annulus or to a second support frame that is placed initially and above the mitral annulus without affecting native leaflet function. Portions of the frame above the securement band allow blood flow radially inwards to reduce stagnation regions in the atrium or outwards below the securement band to help cleanse native leaflets.

STRUCTURALLY FITTED TRANSCATHETER AORTIC VALVE IMPLANTATION DEVICE
20230040369 · 2023-02-09 ·

An aortic valve implantation device that is delivered through a catheter and does not depend only on friction for fixation. In this device, multiple supporting arms (50) are provided on an intermediate portion (102) of a tubular body (105). The supporting arms are “D”-shaped after fully expansion, and are affixed between a narrowest part (73) of the aorta close to the heart and a narrowest part (74) on an aortic annulus (70), so as to achieve sufficient match between the outer surfaces of the support arms (50) and surrounding tissues; Each supporting arm (50) has three landing areas (54) and two bending sections (59). This device can accurately control the position of a valve to be released on the aortic annulus (70).

INTERATRIAL SHUNTS WITH ANCHORING MECHANISMS AND ASSOCIATED SYSTEMS AND METHODS
20230042011 · 2023-02-09 ·

The present technology relates to interatrial shunting systems and methods. In some embodiments, the present technology includes interatrial shunting systems that include a shunting element having a lumen extending therethrough that is configured to fluidly couple the left atrium and the right atrium when the shunting element is implanted in a patient. The system can also include an anchoring mechanism coupled to the shunting element and configured to secure the shunting element within the patients heart.

Knotless suture fastener installation system

A knotless suture fastener installation system for securing medical devices such as cardiac implants. The knotless suture fasteners may be spring-biased so as to grip onto sutures passed therethrough. The system includes a fastener deployment tool with a proximal handle and a distal shaft to which a fastener cartridge attaches. A plurality of disposable cartridges are sequentially attached to the end of the deployment tool and used to secure the medical implant one fastener at a time. The deployment tool may also cut the sutures being fastened.

DEVICES AND SYSTEMS FOR DOCKING A HEART VALVE

Expandable docking stations for docking an expandable valve can include a valve seat, one or more sealing portions, and/or one or more retaining portions. The valve seat can include radiopaque markers affixed to a frame or an impermeable member. The radiopaque markers can indicate a deployment location of the valve. The docking stations can be deployed from a catheter including one or more radiopaque markers. Relative positioning of two or more radiopaque markers can provide an indication of the amount of deployment of the docking station.

ANCHOR POSITION VERIFICATION FOR PROSTHETIC CARDIAC VALVE DEVICES
20230044256 · 2023-02-09 ·

A device for treating a diseased native valve in a patient is provided, the device including a frame structure and a plurality of leaflets. The device can further include a spiral anchor configured to extend around an outer circumference of the frame structure. The anchor can be configured to deliver a contrast agent into or near a target tissue. Other embodiments and methods of use are also provided.

Percutaneous method and device to treat dissections
11571291 · 2023-02-07 · ·

Some embodiments are directed to methods and systems for percutaneously treating dissections in a patient's vasculature, such as, without limitation, the aorta. The method can include deploying a catheter containing a collapsed anchoring element, frame, and cover through a first vessel to an entry point of the dissection. The anchoring element can be secured to the second branch vessel. The frame can be expanded in the first branch vessel. The cover can be unfolded over at least a portion of the entry point. The cover then reduces blood flow into the entry point.

Methods of making collagen fiber medical constructs and related medical constructs, including patches
11589973 · 2023-02-28 · ·

Implantable medical constructs formed by winding using winding support structures that can be flexible and can be integrated into the medical construct with biocompatible fiber(s) and/or yarn(s) and at least one continuous length collagen fiber. The implantable medical construct can include open suture anchor apertures formed using posts during a winding sequence.
