  • Patent number: 10493288
    Abstract: Various configurations of systems that employ leadless electrodes to provide pacing therapy are provided. In one example, a system that provides multiple sites for pacing of myocardium of a heart includes wireless pacing electrodes that are implantable at sites proximate the myocardium using a percutaneous, transluminal, catheter delivery system. Each of the electrodes contains a source of electrical energy for pacing the myocardium and is adapted to receive electromagnetic energy from a source outside the myocardium. The system also includes a source adapted for placement outside the myocardium and that uses locally measured electrocardiograms to synchronize pacing of the heart by sending electromagnetic commands to the electrodes to pace the myocardium surrounding the electrodes. Also disclosed is various configurations of such systems, wireless electrode assemblies, and delivery catheters for delivering and implanting the electrode assemblies.

  • Publication number: 20190274704
    Abstract: 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.

  • Patent number: 10271951
    Abstract: A device is described for crossing the atrial septum to properly size a valve annulus for treatment or replacement, having a catheter with an expandable braided tubular structure attached at its distal end. The proximal and distal end regions of the braided tube have an open structure to allow blood flow to pass freely through the gaps or spaces between the braided fibers. The lumen within the tube includes a temporary, artificial valve that acts similar to a native valve, allowing blood to flow in one direction and preventing blood flow in the opposite direction.

  • Publication number: 20190105158
    Abstract: 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.

  • Publication number: 20190091016
    Abstract: Devices, systems, and methods are provided to treat diseased cardiac valves. The device includes a percutaneous heart valve having an expandable valve frame including valve frame members, a valve leaflet coupled to the valve frame, and an expandable stent anchoring frame coupled to the valve frame including stent frame members defining a first portion and a second portion having greater flexibility than the first portion, where the first portion and the valve frame define a length, and where the stent frame members and the valve frame members along the length provide a contiguous surface over which a delivery device can repeatedly slide over the length in its entirety in two longitudinal directions when the first portion and the valve frame are in a partially expanded state during delivery from the delivery device.

  • Patent number: 10220192
    Abstract: A bulbous valvuloplasty balloon is described that maintains its bulbous shape in its final deployed configuration along with the method of use for post dilation of a TAVR device. The bulbous balloon has two larger diameter bulb segments located on each side of a smaller diameter waist and can be used to post dilate a TAVR device that has been implanted at the site of a stenotic aortic valve. The post dilation causes deformation of the underlying tissues residing outside of the TARV stent structure.

  • Publication number: 20180289948
    Abstract: 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.
