Abstract: An implant and system for reshaping a valve annulus includes an elongate template having one or more anchors which couple directly to a body of the implant or may be indirectly couple through a separate anchor array support. When implanted, the template foreshortens and/or reshapes a peripheral length of the valve annulus can be to improve coaption of native valve leaflets and/or to eliminate or decrease regurgitation of a valve. The template may have one or more skirts augmenting or replacing a defective native valve leaflet function. The template in another example may be coupled to a chordae which is attached to a ventricular wall to improve the heart hemodynamic function. The template may be configured to prevent displacement of an anchor.

Abstract: A stent (scaffold) or other luminal prosthesis comprising circumferential structural elements which provide high strength after deployment and allows for scaffold to uncage, and/or allow for scaffold or luminal expansion thereafter. The circumferential scaffold is typically formed from non-degradable material and will be modified to expand and/or uncage after deployment.

Abstract: The disclosure provides biodegradable implantable devices such as a stent comprising a biodegradable polymeric material wherein the polymeric material is treated to control crystallinity and/or Tg. The stent is capable of expanding at body temperature in a body lumen from a crimped configuration to a deployed diameter and will have sufficient strength to support a body lumen when expanded.

Abstract: Clot aspiration systems intended for removing clot from a blood vessel include an aspiration assembly which will have two or more of the following components: an aspiration catheter, an inner catheter, an intermediate catheter, and an outer catheter, the latter typically being a guiding or other sheath. A transition structure is coupled to a distal end of the aspiration assembly to cover or fill an open distal end of one or more of the components of the aspiration assembly. The transition structure may be configured to facilitate introduction of the aspiration catheter into the patient's vasculature and/or advancement of the aspiration catheter through the vasculature to a target site, such as a cerebral target site which may be occluded with clot, thrombus, or other occlusive material.

Abstract: A system for reshaping a valve annulus includes an elongate template having a length along a longitudinal axis and at least one concavity in a generally lateral direction along said length. The pre-shaped template is positioned against at least a region of an inner peripheral wall of the valve annulus, and at least one anchor on the template is advanced into a lateral wall of the valve annulus to reposition at least one segment of the region of the inner peripheral wall of the valve annulus into said concavity. In this way, a peripheral length of the valve annulus can be foreshortened and/or reshaped to improve coaption of the valve leaflets and/or to eliminate or decrease regurgitation of a valve.
