    摘要： A flexible source wire (10) is provided containing a radioactive source (160) that is capable of maneuvering through a tortuous narrow passage to a treatment site within the body. This source wire (10) includes a thin flexible housing tube (120), housing therein a flexible backbone wire (130), wherein both the tube (120) and the wire (10) are constructed from a material exhibiting little or no memory retention when bent. A radioactive core (160) is provided in the proximal end of the flexible housing tube (120) and abuts the proximal end of the backbone wire (130). Both ends of the source wire (10) are sealed and the proximal end of the source wire (10) is rounded to allow ease of movement as it travels through the bends and turns in the body.

    摘要： An apparatus and method for treating an occlusion or constriction, such as a stenosis in a blood vessel or other conduit in the body, as well as an apparatus and method for treating a tumor or cancerous area occurring around a conduit or duct in the body. The apparatus includes a catheter provided with a ribbed balloon encircling a portion near its distal end. When inserted into the body over a guide wire and transported to the site of the stenosis, the balloon is inflated one or more times and, due to the ribbed balloon, blood perfuses around the catheter during the treatment. A radioactive source of material is inserted through the catheter to the site of the stenosis or cancer where it is maintained in position for a period of time to reduce the occurrence of re-stenosis or cancer. A guide wire provided with a removable core can be utilized to properly maneuver the catheter to the site of the stenosis or cancer.

    摘要： A device for implanting an object, such as a hormone pellet or an electronic transponder beneath the skin of an animal, comprises a hollow needle (1) with an actuating rod (11) slidable therein, a cover (2) movable relative to the needle to enable at least the sharp end of the needle to be shrouded, and a locking mechanism in the form of an abutment (10) movable into a rebate (6), from which it cannot then return. The needle (11) may be mounted at one end of a body (4) which incorporates the locking rebate (6).
