摘要： 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.

摘要： 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.

摘要： 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.

摘要： An aspiration catheter for removing clot from a blood vessel includes a catheter body having a scaffold extending distally from a distal end of the body. An aspiration lumen runs from the distal end to a proximal end of the body, and a central clot-receiving passage in the scaffold is contiguous with the aspiration lumen of the catheter body. A vacuum-resistant membrane covers the scaffold and establishes a clot aspiration path from a distal end of the scaffold to a proximal end of the aspiration lumen, in the catheter body so that applying a vacuum to the proximal end of the aspiration lumen can draw clot into the central clot-receiving passage. The scaffold may have a comical configuration, a cylindrical configuration, or a combination thereof, and at least a distal portion of the scaffold is radially expandable from a delivery configuration to an extraction configuration.
