摘要： A retrieval catheter operable by a single clinician that will neither displace a deployed stent nor cause undue trauma to the vascular lumen or lesion. The retrieval catheter may be sized to accommodate both a guidewire and a balloon wire. The retrieval catheter is easy to navigate through tortuous passageways and will cross a previously deployed stent or stent-graft easily with minimal risk of snagging on the deployed stent or stent graft. The sheath and dilator are adapted to allow a guidewire or balloon wire to pass through the walls of both and to allow the sheath and dilator to move axially with respect to each other.

摘要： Novel catheter constructions comprising thin covering or wrapping materials such as polymer films. A catheter provided with a guidewire catheter lumen having a thin covering that is easily punctured by a guidewire at virtually any desired point along the catheter length. The thin covering may be integral with the catheter shaft, or may be a separate component that covers only the portion of the catheter shaft immediately adjacent the outer portion of the guidewire lumen, or may be a thin tubular construct that surrounds the entire catheter shaft. Moreover, polymer film can be used in combination with one or more elements to produce novel catheter constructions.

摘要： Embodiments herein include devices and methods directed toward creating reverse flow within a vessel and thereby providing protection against embolic debris. Embodiments comprise a catheter and a plurality of occluders that are expandable and adjustable within a lumen to create low-pressure areas that reroute blood flow and embolic debris therein.

摘要： A diametrically adjustable endoprosthesis includes a controlled expansion element extending along at least a portion of a graft and is supported by a stent. The controlled expansion element diametrically constrains and limits expansion of the endoprosthesis. Upon deployment from a smaller, delivery configuration, the endoprosthesis can expand to the initial diameter set by the controlled expansion element. Thereafter, the endoprosthesis can be further diametrically expanded (e.g., using balloon dilation) by mechanically altering the controlled expansion element.

摘要： The present disclosure includes an endoprosthesis delivery system comprising an elongate member, such as a catheter, an endoprosthesis, a covering member disposed about the endoprosthesis, and at least one flexible element situated between the endoprosthesis and the covering member. The covering member can extend beyond an end of the endoprosthesis. In operation, as the covering member is removed, the flexible element can guide the covering member over the end of the endoprosthesis to prevent entanglement between the end of the endoprosthesis and the covering member.

摘要： A seamless, self-expanding implantable device having a low profile is disclosed along with methods of making and using the same. The implantable device includes a frame cut out of a single piece of material that is formed into a three-dimensional shape. The implantable device may comprise an embolic filter, stent, or other implantable structure. The present invention also allows complicated frame structures to be easily formed from planar sheets of starting material, such as through laser cutting, stamping, photo-etching, or other cutting techniques.
