  • Patent number: 11957583
    Abstract: A delivery device for cardiac valve repair implants includes a delivery catheter and an extension member protruding from a distal end of the delivery catheter. The delivery device further includes a control arm assembly having pairs of control arms. Each pair includes a proximal control arm drivable from a handle assembly of the delivery device and a distal arm coupled to a distal end of the proximal control arm and a distal end of the extension member. Proximally driving each of the proximal control arms of the control arm assembly results in expansion of the control arm assembly and corresponding expansion of a cardiac valve repair implant coupled to the control arm assembly.

  • Publication number: 20230390059
    Abstract: Interfaces for delivery systems for delivering and deploying prosthetic heart valves. A prosthetic valve may be secured to a patient's native diseased valve by a spiral-shaped anchor that encircles an outer periphery of the prosthetic valve. In some examples, the interface provides a releasable connection between the anchor and a tether that guides placement of the anchor with respect to the patients native valve. Once the anchor is properly positioned, the prosthetic valve may be positioned and expanded within the patient's native valve and the anchor. The tether-anchor interface can release the anchor from the tether, leaving the anchor and valve prosthesis secured in place within the heart.

  • Publication number: 20230240849
    Abstract: Delivery systems and methods for delivering a valve anchor and a valve prosthesis to a native valve annulus are provided. The anchor can be deployed near the native valve annulus with a tether attached thereto. A portion of the tether can be positioned inferior to the deployed anchor in an inverted configuration for advantageous positioning for adjusting the anchor position and/or deployment of the valve prosthesis. A positioning tool can be tracked over the tether and used to properly position the anchor. The positioning tool can be configured to transition to a stiffened state that includes one or more bends configured to allow efficient positioning of the deployed anchor and to provide room for deploying the valve prosthesis. Once the anchor is properly positioned, the valve prosthesis can be deployed within the native valve annulus and within the valve anchor.

  • Publication number: 20220160546
    Abstract: Systems and devices for facilitating the flow of fluid between a first body region and a second body region are disclosed herein. The devices generally include a drainage and/or shunting element having a lumen extending therethrough for draining or otherwise shunting fluid between the first and second body regions. Further, devices configured in accordance with the present technology may be selectively adjustable to control the amount of fluid flowing between the first and second body regions. In some embodiments, for example, the devices comprise an actuation assembly that drives movement of a flow control element to modulate flow resistance through the lumen, thereby increasing or decreasing the relative drainage rate of fluid between the first body region and the second body region.

  • Publication number: 20220160545
    Abstract: Adjustable flow glaucoma shunts are disclosed herein. In one embodiment, for example, an adjustable flow shunt can include an outflow drainage tube having a proximal inflow region and a distal outflow region. The proximal inflow region can include aperture(s) defining a fluid inlet area positioned to allow fluid to flow therethrough. The shunt further comprises an inflow control assembly at the proximal inflow region. The inflow control assembly can include a control element configured to slidably engage the proximal inflow region and a spring element. The spring element is configured to be activated by non-invasive energy and, upon activation, slidably move the control element along the proximal inflow region such that (a) the one or more apertures are accessible and have a first fluid flow cross-section or (b) the one or more apertures are at least partially covered by the control element and have a second, different fluid-flow cross-section.

  • Publication number: 20220087865
    Abstract: Adjustable flow glaucoma shunts are disclosed herein. In one embodiment, for example, a variable flow shunt for treatment of glaucoma in a human patient includes an elongated outflow tube having (a) a proximal inflow portion configured for placement within an anterior chamber in a region outside of an optical field of view of an eye of the patient, and (b) a distal outflow portion at a different location of the eye. The variable flow shunt further includes a flow control mechanism positioned along the outflow tube between the inflow portion and the outflow portion. The flow control mechanism comprises one or more control elements transformable between an open position that allows fluid to flow through the outflow tube and resistance positions that partially obstruct or attenuate fluid flow through the outflow tube. During operation, the control element(s) are movable between positions in response to non-invasive energy.
