Abstract: Devices, systems and methods are described herein to provide improved treatment of a tricuspid valve. Such treatment may include tricuspid valve replacement, which may include providing a prosthetic tricuspid valve within the tricuspid valve annulus. Delivery systems for delivering the prosthetic tricuspid valve to the tricuspid valve annulus are disclosed herein. Treatment may also include repair of the tricuspid valve.

Abstract: Certain aspects of the disclosure concern a device for repairing or replacing a native heart valve. The device can include a frame including a first set of struts intersecting with a second set of struts at a plurality of strut connection points. The frame can be radially expandable from a radially collapsed state to a radially expanded state. The device can include at least one expansion feature including a screw head and a screw shaft connected to the screw head. The screw shaft can extend through a first strut connection point and a second strut connection point. The device can further include a plurality of penetrating members extending from a first end of the frame. Rotating the screw shaft in a first direction can radially expand the frame from the radially collapsed state to the radially expanded state.

Abstract: Disclosed herein are devices for improving coaption of the mitral valve leaflets to reduce or eliminate mitral valve regurgitation. The devices may be used to perform mitral valve annuloplasty, or to serve as a docking station for a transcatheter prosthetic heart valve. The various embodiments of devices are configured for percutaneous and, in some cases, transvascular delivery. Delivery systems useful for routing the devices to the mitral valve are also disclosed, including catheters, balloons and/or mechanical expansion systems. The devices themselves include at least one tissue penetrating member. Methods of delivery include partially embedding the devices in the mitral valve annulus via at least one tissue penetrating member. Tissue penetrating members may be embedded into the tissue in a simultaneous or a nearly simultaneous fashion. Upon embedding, the devices employ various expansion and/or contraction features to adjust the mitral valve diameter.

Abstract: A method of dissolving a thrombus in a blood vessel for improving blood flow is provided. A filter device includes an expandable filter body fixed to a distal end portion of an outer catheter. The filter device also includes an agitation member disposed along a distal end portion of an inner catheter, wherein the inner catheter is slidably contained within the outer catheter. During treatment, the expandable filter body is expanded within the blood vessel and the inner catheter is advanced relative to the outer catheter such that the agitation member is positioned distal to the filter body. The agitation member is activated for dissolving the thrombus in the blood vessel. After the thrombus is at least partially dissolved, aspiration may be applied for pulling resulting particles into the filter body. The filter device is then retracted into a delivery sheath with the particles captured inside the filter body.

Abstract: A method of capturing and macerating particles in a blood vessel is provided. A vascular filter device is implanted in the blood vessel at a treatment site. The vascular filter device comprises a filter body and an agitation member disposed within the filter body. Movement of the agitation member acts on particles trapped within the filter body for enhancing the dissolution of the particles, thereby reducing the likelihood of filter occlusion and improving the flow of blood through the vessel. The vascular filter device is preferably collapsible for percutaneous delivery to a treatment site. The agitation member is preferably rotatably coupled to the filter body. A power source is provided for moving the agitation member. In various examples, the power source may take the form of an energy storage device, a drive catheter, or a magnetic field.

Abstract: A vascular filter for capturing and breaking apart particles in the blood. The vascular filter includes a filter body and an agitation member disposed within the filter body. Movement of the agitation member acts on particles trapped within the filter body for enhancing the dissolution of the particles, thereby reducing the likelihood of filter occlusion and improving the flow of blood through the vessel. The vascular filter is preferably collapsible for percutaneous delivery to a treatment site. The agitation member is preferably rotatably coupled to the filter body and a flow receiving member is provided for causing the agitation member to rotate. A clutch mechanism may be provided such that the agitation member only rotates when a particle, such as a blood clot, is trapped within the filter body.
