    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.

    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.

    摘要： A coated implantable medical device 10 includes a structure 12 adapted for introduction into the vascular system, esophagus, trachea, colon, biliary tract, or urinary tract; at least one coating layer 16 posited on one surface of the structure; and at least one layer 18 of a bioactive material posited 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 posited 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 coronary 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 removable filter for capturing thrombi in a body vessel is disclosed. The filter comprises a plurality of primary struts comprising proximal and distal portions. Each proximal portion has a first end, wherein the first ends are attached together along a longitudinal axis. Each primary strut extends arcuately along the longitudinal axis and linearly radially. The distal portions of the primary struts are configured to expand in the body vessel, engaging the distal hooks with the body vessel. Each distal portion integrally extends from the proximal portion to a plurality of distal hooks. The distal hooks are substantially equal in size relative to each other.
