Abstract: Prosthetic heart valve devices for percutaneous replacement of native heart valves and associated systems and method are disclosed herein. A prosthetic heart valve device configured in accordance with a particular embodiment of the present technology can include an anchoring member having a first portion configured to engage with tissue on or near the annulus of the native heart valve and to deform in a non-circular shape to conform to the tissue. The device can also include a valve support coupled to a second portion of the anchoring member, configured to support a prosthetic valve and having a cross-sectional shape. In some embodiments, the first portion of the anchoring member is mechanically isolated from the valve support such that the cross-sectional shape of the valve support remains sufficiently stable that the prosthetic valve remains competent when the anchoring member is deformed in the non-circular shape.

Abstract: A prosthetic heart valve (100) includes a flexible anchoring member (110) at least partially surrounding and coupled to an inner valve support (120). The device can further include a prosthetic valve (130) coupled to, mounted within, or otherwise carried by the valve support. The valve support includes a plurality of posts (122) connected circumferentially by a plurality of struts (124), where the posts extend along an axial direction generally parallel to the longitudinal axis (101) and the struts extend circumferentially around and transverse to the longitudinal axis. The posts extend an entire longitudinal height HI of the valve support 120. The device also includes one or more sealing members (140) and tissue engaging elements (170) like spikes.

Abstract: Systems for mitral valve repair are disclosed where one or more mitral valve interventional devices may be advanced intravascularly into the heart of a patient and deployed upon or along the mitral valve to stabilize the valve leaflets. The interventional device may also facilitate the placement or anchoring of a prosthetic mitral valve implant. The interventional device may generally comprise a distal set of arms pivotably and/or rotating coupled to a proximal set of arms which are also pivotably and/or rotating coupled. The distal set of arms may be advanced past the catheter opening to a subannular position (e.g., below the mitral valve) and reconfigured from a low-profile delivery configuration to a deployed securement configuration. The proximal arm members may then be deployed such that the distal and proximal arm members may grip the leaflets between the two sets of arms to stabilize the leaflets.

Abstract: The present invention is directed to a mechanism and procedure for adjusting a cardiac implant during the early post-operative period, such as, for example, the first 2-5 days after surgery. During the implant procedure, an adjustment tool is releasably attached to the adjustable implant. The adjustment tool remains connected to the implant following the procedure and extends from the patient's body to allow for post-operative adjustment under normal beating heart conditions. Once the implant is adjusted, the adjustment tool is configured to release from the implant and be removed from the patient's body without requiring access to the patient's heart.

Abstract: A prosthetic heart valve device (100) for percutaneous replacement of a native heart valve includes an expandable retainer (110) at least partially surrounding and coupled to an inner valve support (120). The device can further include a prosthetic valve (130) coupled to the valve support. The retainer forms a donut-shaped flange (190) having an arcuate outer surface (142) for engaging tissue and an inner lumen defining a passage for blood to flow through the valve support. The retainer can include a plurality of circumferentially positioned, resiliency deformable and flexible ribs (114) which are coupled at their downstream ends 116 to the valve support 120. The flexible ribs, in one embodiment, can have a general C-shape configuration with the tips (117) of the flexible ribs and an opening (119) of the C-shape configuration oriented toward a longitudinal axis (101) of the device.

Abstract: An implantable device is provided for controlling at least one of shape and size of an anatomical structure or lumen. An implantable device has an adjustable member configured to adjust the dimensions of the implantable device. An adjustment tool is configured to actuate the adjustable member and provide for adjustment before, during and after the anatomical structure or lumen resumes near normal to normal physiologic function.

Abstract: An implantable device system for controlling the dimensions of internal anatomic passages corrects physiologic dysfunctions resulting from a structural lumen which is either too large or too small. Implantable devices are disclosed which employ various mechanisms for adjusting and maintaining the size of an orifice to which they are attached. Systems permit the implants to be implanted using minimally invasive procedures and permit final adjustments to the dimensions of the implants after the resumption of normal flow of anatomic fluids in situ.
