    摘要: An expandable stent and delivery system is provided for enhancing luminal dilation of a blood vessel. The delivery system includes proximal, intermediate and distal cylindrical members disposed on and spaced apart along an elongated core member such that first and second gaps are formed. The expandable stent includes proximal and distal anchor members which align with the gaps. The expandable stent is mounted on the intermediate cylindrical member, and the anchor members are disposed within the gaps thereby locking the stent onto the core member.

    摘要: A constraining sheath for use around an endoprosthesis (e.g., a stent device, with or without a graft covering), which may be a balloon expandable endoprosthesis but more preferably is a self-expanding prosthesis. The endoprosthesis is coaxially enclosed within the constraining sheath, which is an outer, disruptable, preferably implantable tubular sheath, preferably made of ePTFE. The constraining sheath and endoprosthesis are preferably mounted together as an assembly on an angioplasty balloon for delivery. Deployment of the endoprosthesis entails inflating the angioplasty balloon to a pressure sufficient to disrupt or break the constraining sheath in a prescribed fashion, thereby allowing a self-expanding endoprosthesis to spontaneously deploy. The constraining sheath of ePTFE may be attached to the endoprosthesis and implanted along with the device, or alternatively attached to the balloon catheter shaft and removed with the balloon catheter. The angioplasty balloon's working length is preferably shorter than the length of the endoprosthesis. An endoprosthesis assembly incorporating a constraining sheath according to one embodiment of the invention is also provided with an additional packaging sheath.

    摘要: A reduced diameter stent/graft deployment catheter and a method of insertion for said catheter. The delivery sheath portion of the catheter, i.e. the distal portion of the catheter containing the stent/graft, has a larger outer diameter than the remaining proximal portion of the catheter. The reduced outer diameter of the body of the catheter allows for the use of a smaller diameter introducer sheath. The method of inserting said catheter comprises the following steps: First, the delivery sheath portion of the catheter is inserted into the patient. Next, an introducer sheath, with an outer diameter which is no larger than the outer diameter of the delivery sheath, is disposed about the catheter and its distal portion inserted into the patient. The catheter is then advanced into the patient and the stent/graft deployed.

    摘要: A stent graft device has an upper main tubular portion dividing into two tubular limbs and is adapted for location in an aorta having an aneurysm. The stent graft device is well suited for an aorta having a restricted section having an inner diameter smaller than the sum of the inner diameters of the iliac arteries, which branch from the aorta. The diameters of the two tubular limbs are sufficiently small to allow for both tubular limbs to be deployed side-by-side in a fully expanded state within the restricted section without being constrained by the aorta inner surface. The limbs also have distal end portions having diameters larger than the diameters of limbs at the area near the restricted section for being retained within the iliac arteries.

    摘要: A stent for insertion into a vessel of a body and used in connection with a foil sheet, where the foil sheet comprises a radioactive material, is described. The stent and foul sheet are positioned so that the radioactive material in the foil sheet can deliver a desired dosage to an prescribed area, thereby reducing the distance for delivering the radioactive dose. The radioactive material may comprise carrier-free palladium 103. The foils screen may further comprise a shielding lay on the side for directing the dosage. A method for placing the stent and foil into a vessel of a body is also described.

    摘要: A bypass graft includes a tubular portion having an internal tubular diameter and a first end and a second end. The tubular portion has a central axis. A flared portion has an adjoining end, wherein the adjoining end of the flared portion is integrally formed on and is substantially concentric with the second end of the tubular portion, and a flared end, wherein the flared end has a flared end internal diameter, such that the internal flared end diameter is greater than the internal tubular diameter. The flared portion includes a circumferential skirt for surgical attachment of the graft to a patient's blood vessel. A method for manufacturing a bypass graft, includes the steps of providing a mandrel having a tubular portion and a flared end with a flared end central axis; forming a layer of polyurethane over the mandrel; drying the layer of polyurethane on the mandrel; forming a skirt edge around the flared end of the mandrel to form an opening at a predetermined angle to the flared end central axis; forming a second edge around the tubular portion of the mandrel, and removing the graft from the mandrel.

    摘要: A removable stent system and method for extraction of a removable stent from a target site is disclosed. The removable stent includes a removable stent having a collapsible end and a collapsing element configured for coupling with a removal tool. The collapsing element can be configured as a lasso or can be movable between two positions when deployed at a target site in vivo. The removable stent overcomes disadvantages and limitations of previous types of stents as well as overcoming complications during or following stent deployment in vivo. The removable stent further includes features that increase its ease of use and reduce the maneuvering required of devices or tools used to remove the stent. This then decreases the amount of effort required by the physician, the procedure time, and the level of discomfort experienced by a patient during the procedure.

    摘要: A woven tube having a warp direction oriented lengthwise to the tube and a fill direction oriented circumferentially of the tube is disclosed. The tube is woven from a plurality of elastic warp yarns arranged parallel to the warp direction and a plurality of elastic fill yarns arranged parallel to the fill direction. The tube has one or more discrete regions of relatively greater flexibility formed in either the warp or fill directions at locations along the tube. The flexibility is oriented in the warp direction or the fill direction by weaving either the warp or fill yarns, respectively, under relatively less tension.

    摘要: A prosthetic device for sustaining a vessel or hollow organ lumen (a stent) having a tubular wire frame (1) with rows of elongate cells (2) each having a larger axis and a smaller axis. The cells are arranged with the larger axis in the circumferential direction of the frame (2) and the smaller axis parallel to the axial direction thereof. Each cell is formed by two U-shaped wire sections, and in a plane perpendicular to the longitudinal axis one of the branches of the U-shaped wire sections in one row form together a closed ring shape (4) which provides the frame (1) with large radial stiffness. In the axial direction the frame (1) has only low stiffness so that it easily conforms to the vascular wall even if this deforms due to external loads. The interconnection between the cells (2) may be flexible.
