    摘要: A flat-form separation device (12) is made of two half-section members (22, 22') which are fastened together by a series of fasteners (38) to define therebetween a receiving channel within which an expansion device (40) is received. Aside from the receiving channel and any apertures which are to receive mechanical fasteners, the separation device (12) is solid throughout and free of other channels or cavities. The device (12) includes a pair of joinder flanges formed by mating half-flange segments (28a and 28b), which contain apertures (32 and 34) by which the flat-form separation device (12) may be secured to structures (48, 50) which are to be temporarily joined by the device (12). Because of the cross-sectional profile of the half-section members (22, 22'), they may be made by manufacturing techniques, such as machining, which enable the use of alloys or metals which are much tougher and stronger than those which can be extraded to form prior art hollow-form separation devices (14). Several embodiments of the flat-form separation device (12) are disclosed. Both flat-form separation devices (12) and hollow-form separation devices (14) may be combined in a segmented separation structure (10).

    摘要: A thrombolysis catheter system having a fixed length infusion zone is disclosed. The invention contemplates apparatus, method and kit aspects. The apparatus, which has the capability to track a guidewire, uses a multilumen catheter to deliver radially thrombolytic agent to an infusion zone defined by one or more balloon means. In one aspect, with an occluder means, a primary lumen of the catheter is used both for catheter placement and delivery of fluid. The method discloses utilization of radiopaque indicia to place the catheter in proximity to the occlusion or diseased tissue to be treated. The kit includes a catheter of the invention in conjunction with a steerable guidewire and a tip occluder wire, either or both of the tip occluder wire and the guidewire having an enlargement on their distal tip which cooperates with a reduced diameter portion of the catheter lumen.

    摘要: First and second sealed, sterile containers, having respectively communicating first and second fluid transfer tubes, the tubes having diaphragms occluding the bores thereof, may be connected together in sterile manner for the sterile transfer of the contents of one container to the other. To accomplish this, one point of a double-pointed, hollow spike is inserted into each of the bores of the fluid transfer tubes, at the free ends thereof, the spike being proportioned to tightly and sealingly fit into each bore of the fluid transfer tubes. Thereafter, the spike and that portion of the tubes extending from the diaphragms to the free ends thereof are sterilized. Then the points of the spike are moved to rupture the diaphragms, to open a flow channel, and the sterile contents are transferred. The fluid transfer tube of the container receiving the desired sterile contents is then resealed, prior to breaking sterility by opening the connection.
