    摘要： A device and system for closure of an opening formed in a body vessel includes a bioabsorbable grasping member and locking member. The grasping member includes grasping lingers that are radially collapsible to the closed positions by movement of the locking member over the fingers. A distal portion of the fingers is configured to grasp an outer wall portion of the body vessel surrounding the opening when the fingers are in the open position. Movement of the locking member can cause the fingers to at least substantially close the vessel opening. Structural features on the fingers and/or locking member can inhibit proximal or distal movement of the locking member when in a locking position. A detachable arm can be coupled to the grasping member to facilitate placement of the grasping member. A sheath can fit over the detachable arm and be configured to move the locking member over the fingers.

    摘要： A catheter apparatus (20) and radiation dosimetry unit indicator (21) for delivery of a prescribed radiation dose to a patient. The catheter is filled with a radiation carrier material such as an inert radioactive gas (12) for the treatment of, for example, restenosis after angioplasty, and malignancies. The inflated catheter includes a plurality of discrete chambers such as balloon sections (22, 24, 26) for transporting the radioactive carrier material, and a plurality of discrete chambers (32, 34, 36) enabling substantial blood flow through the artery during treatment with the prescribed radiation. The inflated catheter can also comprise a one-unit balloon. A specific metal coating enhances the radiation dose delivered to the target. The wall (25) of the inflation lumen attenuates transmission dose to the blood circulating through the hollow inner lumen of the catheter device. The system also creates increased by-product radiation, from the impact of beta particles and gamma protons traveling toward the lumen wall. A radiation dosimetry unit indicator (21) is positioned, disposed, or affixed to a calibrated catheter to assist the physician in prescribing radiation activity and exposure times.

    摘要： A medical device for localizing a nonpalpable breast lesion. The device includes a tubular introducer needle and a wire guide positioned therein for inserting into a breast to the site of the lesion. The wire guide includes a distal portion having a preformed, 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. The needle is inserted with the wire guide positioned therein into the breast to the site of the lesion and from the distal portion of 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 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 the surgeon to the lesion site during subsequent surgery.

    摘要： A dual lumen hemodialysis catheter. The catheter includes a tube having a circular external cross section which is rotatably received within a fitting. The fitting may be attached to the patient by sutures or the like and rotatably mounts the tube of the catheter. Stop means are provided on opposite sides of the fitting preventing the tube of the catheter from moving longitudinally relative to the fitting. The catheter may be rotated relative to the fitting in order to readjust the rotational position of the tube inside the patient's blood vessel without longitudinal movement of the tube. The catheter is cut off at its distal end perpendicularly to the length of the tube in order to define the mouth of one lumen. The tube is tapered from the cut off distal end to a point proximal of the distal end, said point being approximately 3 cm from the distal end. The taper of the tube defines at least a portion of the mouth of the second lumen.
