摘要： A medical device (10) for localizing a nonpalpable breast lesion (20). The device includes a tubular introducer needle (11) and a wire guide (14) positioned therein for inserting into a breast (25) to the site of the lesion. The wire guide includes a distal portion (16) which is preformed into a resilient helical coil configuration for locking into position about the lesion. The distal portion includes a superelastic metallic alloy for maintaining the helical coil configuration after repeated extensions from and retractions into the needle passageway. With a visualization aid such as an X-ray film or ultrasound, a radiologist typically inserts the needle with the wire guide positioned therein into the breast to the site of the lesion and extends the distal portion of the wire guide from the needle. The distal end of the needle includes a plurality of indentations for enhancing the ultrasound visualization thereof. As the distal portion of the wire guide emerges from the needle, the acuate distal end (17) of the wire guide cuts into and scribes a helical path about the tissue distal to the lesion. The remainder of the distal portion of the wire guide follows the path scribed by the acuate distal tip and locks about the tissue distal to the lesion. Should the needle and wire guide not be appropriately positioned, the distal portion of the wire guide is retracted into the passageway of the needle to reposition the needle and guide. After desired positioning, the needle is removed with the wire guide remaining in a locked position distally about the lesion for guiding guides the surgeon to the lesion site during subsequent surgery.

摘要： An apparatus (10) for filtering blood in a blood vessel of a patient comprises a catheter (30) which is introduced into the blood vessel and advanced to a desired location within the blood vessel, a positioning means (12) having a filter (13) distally attached thereto to be guided through the catheter. In use, the filter is positioned at a location beyond the distal end of the catheter within the blood vessel with the positioning means. The positioning means is then locked to the catheter. The catheter is then anchored to an object located outside of the blood vessel. Thereafter, an amount of blood is filtered within the blood vessel with the filter. The filter can be readily repositioned by unlocking the positioning means from the catheter, repositioning the filter within the blood vessel with the positioning means and then relocking the positioning means to the cather.

摘要： A multiple-sided medical device (10) comprises a frame (11) comprising wire or other resilient material and having a series of bends (12) and interconnecting sides. The device is pushed from a delivery catheter into the lumen of a duct or vessel and may include one or more barbs (16) for anchoring purposes. A full or partial covering (45) of fabric or other flexible material such as DACRON, PTFE, or a collagen-based material such as small intestinal submucosa (SIS), may be sutured or attached to the frame to form an occlusion device (51), a stent graft (75), or an implantable, intraluminal valve (43) such as for correcting incompetent veins in the lower legs and feet.

摘要： A multiple-sided valve for implantation within a body vessel comprising a frame comprising a bioabsorbable material is provided. The devices can be pushed from a delivery catheter into the lumen of a duct or vessel and may include one or more barbs for anchoring purposes. A full or partial covering of fabric or other flexible material, or a bioabsorbable material, including a collagen-based material such as small intestinal submucosa (SIS), may be attached to the frame to form an occlusion device, a graft, or an implantable, intraluminal valve such as for correcting incompetent veins in the lower legs and feet.

摘要： An implantable graft, which may be inserted into a fistula tract to occlude the primary opening of the fistula, is provided. To prevent unintentional displacement of the graft or extrusion of the graft from the fistula of a patient, the graft may be provided with a cap that extends laterally from at least one end of the body of the graft, where the cap may be integral with the body of the graft, attachable to at least one end of the body of the graft, and/or moveable along the body of the graft. The graft may also have a tail that extends from one end of the body of the graft to assist in placement of the graft in a fistula tract. The graft may be an integral unit made of a single material, such as a heterograft material, or may include distinct components made of the same or different materials. Methods for closing a fistula tract are also provided.

摘要： A coated implantable medical device (10) includes a structure (12) adpated f or introduction into the vascular system, esophagus, trachea, colon, biliary tract, or urinary tract; at least one coating layer (16) positioned on one surface of the structure; and at least one layer (18) of a bioactive materia l positioned on at least a portion of the coating layer (16), wherein the coating layer (16) provides for the controlled release of the bioactive material from the coating layer. In addition, at least one porous layer (20) can be positioned over the bioactive material layer (18), wherein the porous layer includes a polymer and provides for the controlled release of the bioactive material therethrough. Preferably, the structure (12) is a coronar y stent. The porous layer (20) includes a polymer applied preferably by vapor or plasma deposition and provides for a controlled release of the bioactive material. It is particularly preferred that the polymer is a polyamide, parylene or a parylene derivative, which is deposited without solvents, heat or catalysts, and merely by condensation of a monomer vapor.

摘要： A catheter apparatus and radiation dosimetry unit indicator for delivery of a prescribed radiation dose to a patient. A radiotherapy source vial (700) includes a fluid container (701) of radioactive fluid with a seal (702,731) disposed about the container. Seal (702,731) is moveable with respect to container (701) to change the contained volume therein. A radioactive fluid transport site (703) is in communication with the contained volume and with an exterior (726) of the container (701), and may include a septum (707) or a valve (711). An engagement mechanism (704) is connectable to an external control mechanism (706) whereby the contained volume in the radioactive fluid container can be decreased and increased by actuation of the external control mechanism.
