摘要： A method and apparatus for injecting radiographic dye during angiography, are provided. A deformable holding chamber (14) is interposed between a contrast dye bottle (12) and a syringe manifold (16). A one-way valve (36) and an integral disconnect/flow stop (28) are connected between the bottle (12) and the holding chamber (14). A vent (54) is provided in the holding chamber (14), with a second one-way valve (58). Squeezing and releasing the deformable chamber (14) fills the chamber (14) from the bottle (12). The holding chamber (14) contains a floating baffle (52) which acts as a shutoff valve by plugging the chamber outlet if the chamber (14) becomes empty. The syringe (50) is used to withdraw dye from the holding chamber (14). If dye remains in the bottle (12) after performance of the procedure, the disconnect/flow stop fitting (28) can be disconnected, and the dye can be saved.

摘要： A method and apparatus for blocking a body passageway by inserting an expandable frame (40) into the passageway and expanding the frame (40) with an expandable balloon (46) to partially embed the frame (40) in the walls of the passageway. The frame (40) can carry a separate sealing membrane (36), or the balloon (46) can function as the sealing membrane. The sealing membrane (36), the frame (40), or the balloon (46) can also carry a clot promoting substance. The balloon (46) can be removed along with the inflation tube after the expansion procedure, if it is not serving as the sealing membrane (36), or the balloon (46) can be detached from the inflation tube and left in place, either as a sealing membrane or simply to lock the frame in place. The frame can be maintained in its expanded state by being plastically deformed during the expansion step.

摘要： This invention is a catheter (10) for use with a radioactive source (16) within the catheter (10) to irradiate a selected area of a blood vessel in combination with angioplasty procedures, to prevent restenosis of that area of the blood vessel. The catheter (10) has a guidewire channel (18) formed near its distal end to facilitate use of the catheter (10) as a rapid exchange catheter, allowing insertion of the catheter over a guidewire (20) also used in performance of an angioplasty procedure. The catheter (10) can also have a guidewire channel (19) formed near its proximal end to provide O-ring sealing surface and to facilitate free guidewire movement. The catheter (10) also has a closed end (13) to retain the radioactive source (16) within the catheter (10). The catheter (10) can be also be provided with a centering balloon (22) or a set of centering wire loops (50) to center the radioactive source (16) radially within the blood vessel.
摘要翻译：本发明是一种与导管（10）内的放射源（16）一起使用的导管（10），用于结合血管成形术过程照射血管的选定区域，以防止该血管区域的再狭窄。导管（10）具有形成在其远端附近的导丝通道（18），以便于将导管（10）用作快速交换导管，允许将导管插入也用于实施血管成形术的导丝（20）程序。导管（10）还可以具有在其近端附近形成的导丝通道（19），以提供O形环密封表面并且便于自由导丝移动。导管（10）还具有封闭端（13）以将放射源（16）保持在导管（10）内。导管（10）也可以设置有对中球囊（22）或一组对中线环（50）以使放射源（16）在径向内居中在血管内。

The catheter (10) has a guidewire channel (18) formed near its distal end to facilitate use of the cather (10) as a rapid exchange catheter, allowing insertion of the catheter (10) over a guidewire (20). The catheter (10) has a radiation lumen (14) with a sealed end to retain the radioactive source (16) within the catheter (10). The radiation lumen (14) is sufficiently longer than the guidewire channel (18), keeping the radiation source (16) segregated from the blood, allowing the use of a non-sterile radiation source. The catheter (10) can be provided with a balloon (22) or a set of wire loops (50) to center the radioactive source (16) radially within the blood vessel.
