A catheter system and corresponding methods are provided for accessing a blood vessel true lumen from a sub-intimal plane of the vessel. The catheter includes components that are symmetric about the longitudinal axis and allow for reentry without the need to ensure a correct orientation of the cannula.

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.

Described are various embodiments of an improved endoprosthesis that includes a generally tubular graft, a plurality of independent stent hoops connected to the graft and at least one suture. The at least one suture connects one apex of one stent hoop to two apices of another stent hoop to reduce a predetermined distance between distinct stent hoops so that in a released configuration in a body vessel, the stent-graft is curved away from the longitudinal axis to conform to the body vessel and reduce formation of a gap between one end of the stent-graft with an inner surface of the body vessel.

A dilator (10) for sheathless access to a vessel of a patient, having a distal portion (14) with a maximal outer diameter that extends from a distal end (12) to a guidewire exit port (16) and a proximal portion (18) with a reduced profile that extends from the guidewire exit port to the proximal end (20) and a lumen (22) that extends between the distal end and the guidewire exit port. A first guidewire (42) may be positioned within the vessel and the dilator advanced over the guidewire. A guide catheter may then be advanced over the dilator.

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.


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.
