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.

Abstract: Devices and methods are provided for an implantable medical device which is degradable over a clinically relevant period of time. The medical devices may have the form of implants, graft implants, vascular implants, non vascular implants, wound closure implants, sutures, drug delivery implants, biologic delivery implants, urinary tract implants, inter-uterine implants, organ implants, bone implants including bone plates, bone screws, dental implants, spinal disks, or the like. In preferred embodiments, the implantable medical device comprises an implantable luminal prosthesis, such as vascular and non-vascular stents and stents grafts.

Abstract: Luminal prostheses comprise scaffolds having coatings adhered to at least a portion of their outer surfaces. The surfaces are modified to enhance binding of the coatings. For example, the surfaces may be microblasted, laser treated, chemically etched, exposed to plasma, or exposed to a corona discharge, allowing a polymeric coating to adhere to the scaffold more tightly than in the absence of the surface modification. The coatings can be used to deliver therapeutic or other agents dispersed therein.
