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

Abstract: 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.

Abstract: Balloon catheters, sleeves, cages, and endoluminal prostheses are provided with stress-applying and spacing features coupled to expandable surfaces thereof. The stress-applying features may have blunt and/or rounded contact regions which contact tissue or calcified regions in the vasculature. The contact regions dent or fracture occlusive material on the wall of a vascular lumen and/or patient valve leaflets when expanded. The spacing features permit blood, drug, and contrast perfusion past structures expanded in the vasculature, particularly balloon catheters.

Abstract: Devices, systems, and methods are provided including a structure having one or more surfaces configured for internal use within a patient's body and one or more therapeutic compositions comprising one or more active substances including a direct factor Xa inhibitor, and a direct factor IIa inhibitor disposed in or on the structure. The structure is configured to be positioned adjacent an injury site in the patient's body. The one or more active substances optionally include an anti-proliferative agent. The therapeutic composition is formulated to release the one or more active substances to the injury site to provide one or more of inhibit clot formation, promote clot dissolution, inhibit or dissolute inflammation, inhibit vessel injury, increase time before clotting, and/or inhibit cell proliferation.

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.

Abstract: An aspiration catheter includes a catheter body having a proximal end, a distal end, and an aspiration lumen therebetween. A distal segment comprising an expandable distal tip of the aspiration catheter comprises a membrane and an expandable supporting structure, such as a scaffold, configured to radially expand the expandable distal tip. The expandable supporting structure may include supporting elements and other features which increase resistance to collapse of the expandable membrane under vacuum or negative pressure applied to aspirate clot through the aspiration lumen in the expanded configuration.
