Described are various embodiments of an improved endoprosthesis that includes a generally cylindrical graft portion that extends along a longitudinal axis to define a flow passage and a plurality of stent hoops. The plurality of stent hoops are connected to the graft portion and disposed in a spaced apart relationship along the longitudinal axis. There is at least a first suture disposed along on the outer surface of the main body. The first suture connects at least two of the spaced apart stent hoops together. The first suture also includes unidirectional barbs (or multidirectional barbs) configured to reduce movement of the main body with respect to a direction of blood flow in an artery.

Various embodiments for a composite endovascular device (100) (and variations thereof) that include an inner polymer structure (102) and an outer thin-film shape memory structure (106). The inner polymer structure extends from a distal end to a proximal end along a longitudinal axis (L). The outer thin-film shape-memory structure has an inner thin-film surface coupled to the outer surface (102b) of the inner polymer structure from the distal end to the proximal end with a retrieval member (108) at the proximal end to allow for the prosthesis to be retrieved after placement in a body vessel. The inner polymeric structure can be blended with a suitable bio-active agent or the agent can be loaded into the pores. The device can be permanent or temporary by virtue of being retrievable.


A deflecting guide catheter for use in minimally invasive medical procedure such as the treatment of mitral valve regurgitation by reshaping the mitral valve annulus using one or more plications of annular or adjacent tissue each fixed by a retainer is described. The catheter includes an elongated tubular portion having various durometers along its length and at least one puller wire attached to an anchor band near the distal end. The deflecting guide catheter is used to provide a means for guiding a plication device or other medical instrument into a desired position within the vasculature or heart chambers of a patient.


A biocompatible metallic material may be configured into any number of implantable medical devices, including intraluminal stents. The biocompatible metallic material may comprise a magnesium alloy. The magnesium alloy implantable medical device may be designed to degrade over a given period of time. In order to control the degradation time, the device may be coated or otherwise have affixed thereto one or more coatings, one of which comprises a material for controlling the degradation time and maintain a pH neutral environment proximate the device. Additionally, therapeutic agents may be incorporated into one or more of the coatings on the implantable medical device.

A balloon catheter or stent delivery system for medical treatment of a patient has a proximal hub (12), a balloon (16), and a shaft (14). The catheter shaft has a rapid-exchange configuration, and a tubular outer body (24) that includes a hypotube (48) extending from the catheter proximal end to a position at or near a proximal leg of the balloon. An inner tubular body (26) defines a guidewire lumen extending from a distal guidewire port (30) at the catheter distal end to a proximal port (18) located at a position between the balloon and the hub The hypotube has an aperture for accepting the inner body proximal end, and a circumferential cut pattern. The cut pattern adds flexibility, and may extend from the hypotube distal end to a position proximal of the proximal guidewire port


Medical devices, and in particular implantable medical devices, may be coated to minimize or substantially eliminate a biological organisms reaction to the introduction of the medical device to the organism. The medical devices may be coated with any number of biocompatible materials. Therapeutic drugs, agents or compounds may be mixed with the biocompatible materials and affixed to at least a portion of the medical device. These therapeutic drugs, agents or compounds may also further reduce a biological organisms reaction to the introduction of the medical device to the organism. In addition, these therapeutic drugs, agents and/or compounds may be utilized to promote healing, including the formation of blood clots. The drugs, agents, and/or compounds may also be utilized to treat specific diseases, including vulnerable plaque. Therapeutic agents may also be delivered to the region of a disease site. In regional delivery, liquid formulations may be desirable to increase the efficacy and deliverability of the particular drug. Also, the devices may be modified to promote endothelialization. Various materials and coating methodologies may be utilized to maintain the drugs, agents or compounds on the medical device until delivered and positioned. In addition, the devices utilized to deliver the implantable medical devices may be modified to reduce the potential for damaging the implantable medical device during deployment. Medical devices include stents, grafts, anastomotic devices, perivascular wraps, sutures and staples. In addition, various polymer combinations may be utilized to control the elution rates of the therapeutic drugs, agents and/or compounds from the implantable medical devices.


An expandable, implantable medical device, such as an intraluminal stent (10) fabricated from polymeric materials, includes a plurality of elongated struts (16) in consecutive series and alternating stress concentration junctions (18) interconnecting ends of adjacent struts (16). When the stent (10) is in an expanded condition, the adjacent struts (16) form expanded substantial V- shapes and stresses are concentrated within the junctions (18). The junctions (18) define pivot points (P) for the respective attached, adjacent struts (16). Each of the pivot points (P) is located substantially on a line bisecting the V -shapes formed by the struts (16), when the stent (10) is expanded.
