A thrombectomy system may include an elongate shaft that defines a high pressure lumen and a low pressure lumen. The high pressure lumen may terminate near an end of the low pressure lumen. An expandable capture basket may be disposed near the end of the low pressure lumen. A thrombectomy apparatus may include an elongate shaft, an evacuation lumen extending within the elongate shaft and a high pressure lumen extending within the elongate shaft. A capture apparatus may be disposed within a wire lumen that extends within the elongate shaft such that the capture apparatus extends distally from the wire lumen.

Thrombectomy apparatus and method

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.

Two component straddle heart valve system

A transseptal system can include a guidewire, a dilator, and a deflectable sheath configured to safely deliver a puncture needle through a septal wall associated with the fossa ovalis and into a central region of the left atrium of a heart. The dilator can include a dilator nose having a first outer diameter and a dilator beveled segment, extending proximal of the dilator nose, tapering from a second, greater outer diameter to the first outer diameter. The length and interplay of the puncture needle and the dilator nose can be configured such that the puncture needle is inhibited from bending and impinging upon the left side of the atrial septum of the heart during use. A body of the guidewire can include at least one loop segment to provide stable support in the left atrium for delivery of a diagnostic or therapeutic device along its more proximal portions. The deflectable sheath can position and align the dilator nose relative to the fossa ovalis.

Transseptal systems, devices and methods

Some embodiments of pacing systems employ wireless electrode assemblies to provide pacing therapy. The wireless electrode assemblies may wirelessly receive energy via an inductive coupling so as to provide electrical stimulation to the surrounding heart tissue. In certain embodiments, the wireless electrode assembly may include one or more biased tines that shift from a first position to a second position to secure the wireless electrode assembly into the inner wall of the heart chamber.

Cardiac stimulation system

A device and method for compressing a renal artery prior to delivery of radiofrequency ablative energy to the renal nerves. The device includes a stent structure with a focal region that expands outwards to place the RF electrodes located on the stent structure in close proximity to the renal nerves. A covering is applied to the stent structure to prevent intimal hyperplasia.

Compression stent device and methods

A head covering to reduce the force from an external surface on the head of an individual. The head covering is formed from thin polymeric tubes that are inflated by blowing via lung exhalation. The head covering is light weight and can be folded into a small in volume such that it is easily carried in a shirt or pant pocket.

Inflatable head covering

An occlusion device intended for blocking perivalvular leak channels that are found following heart valve implantation between the heart valve and the surrounding tissue. The occlusion device has a stent and a covering that is attached to the stent surface. A blocking fabric extends across the lumen of the stent to block blood flow. The stent pattern and wall structure provide for small radius of curvature bends to fill narrow channels that cause the perivalvular leaks.

Proximal perivalvular occlusion system

A method for transcatheter delivery to a native heart valve needing replacement. A first component is attached to the native annulus upstream of the native leaflets maintaining native leaflet function, and is held to the native annulus by barbs that are activated by a torus balloon after the first component is fully expanded. The torus balloon can be implanted along with the support frame. A limiting cable restricts further expansion of the first component and holds a second component that contains the replacement leaflets.

Two component mitral valve device and methods

Straddle mitral valve device and methods

A transcatheter stent-valve having replacement leaflets that are attached along their free edges. The stent-valve frame has supports that extend distally of the replacement leaflets to two fastening sites. The replacement leaflets are attached along a leaflet base forming a linear attachment to the stent-valve frame. The free edges of the leaflets have cords attached; the cords attach the free edges of the leaflets to the fastening sites located on the supports. The stent-valve can be a single component stent-valve or it can be a second component of a dual component stent-valve.

Mitral valve with free edge support

Apparatus, systems, and methods for percutaneous valve replacement and/or augmentation are provided. The apparatus includes a valve having a valve frame, a valve leaflet coupled to the valve frame, and a leaflet transition member coupled to the valve leaflet. The valve leaflet and leaflet transition member can transition from a first position where the valve leaflet and leaflet frame are at least partially outside a lumen of the valve frame to a second position where the valve leaflet and the leaflet transition member are within the lumen of the valve frame.

Percutaneous valve, system and method

A device for compressing a renal artery prior to delivery of radiofrequency ablative energy to the renal nerves. The device includes a stent structure with a focal region that expands outwards to place the RF electrodes located on the stent structure in close proximity to the renal nerves. A covering is applied to the stent structure to prevent intimal hyperplasia.
