摘要： Radioactive therapeutic seeds include a carrier structure bearing a radioactive isotope and a radiopaque marker. According to embodiments of the invention, the seeds include a central plug provided with an axial marker and a relatively transverse bore extending through the marker. A second marker may be positioned in the bore, thereby radiographically distinguishing a seed provided with the second marker relative to a seed not provided with the second marker. According to another embodiment of the invention, the isotope is deposited on the outer surface of a hollow radiolucent tube. A biologically-compatible, radiolucent, surface-sealing layer seals the external surface of the tube. A radiopaque marker wire of selected length is positioned in the hollow of the tube. Seeds may be radiographically distinguished from one another by providing seeds with marker wires of different lengths. Each embodiment permits at least two groups of seeds to be radiographically distinguished from one another by the use of differing marker configurations. Each embodiment is further capable of being selectively marked by the physician prior to implantation of the seeds, or by the manufacturer for delivery to the physician in radiographically distinguishable sets. As a result, seeds having different levels of radiation emission can be distinguished in vivo and their effect monitored by the physician.

摘要： A vacuum powered pump includes a spring biased piston or diaphragm in a vacuum chamber coupled to a source of vacuum. When vacuum is applied to the vacuum chamber, the piston or diaphragm is moved in a first direction against the spring. A delayed action valve is coupled to the vacuum chamber to allow ambient air to enter the chamber only after the piston or diaphragm has been moved a substantial distance in the first direction. When the delayed action valve opens, air enters the vacuum chamber and the force of the entering air together with the bias of the spring propels the piston or diaphragm in a second direction opposite the first direction. The delayed action valve automatically closes and the process repeats so long as a vacuum source is coupled to the vacuum chamber. The reciprocal movement of the piston or diaphragm effects a pulsatile pumping of fluid through a fluid chamber having at least one check valve.

摘要： An endoscopic instrument is described having a fluid chamber, a cannula, a shell, a first locking mechanism, and a probe with a second locking mechanism. The fluid chamber has proximal and distal ends. The hollow cannula is coupled to the distal end of the fluid chamber. The port is located at the proximal end of the fluid chamber. The shell houses the fluid chamber, the port, and the first locking mechanism. The probe extends through the port, through the fluid chamber, and through the hollow cannula. In a first fully inserted position, the distal end of the probe extends past the distal end of the cannula. When the probe is partially withdrawn from the shell, the first locking means releasingly engages the second locking means on the probe. Different spring loaded mechanism are described, including one mechanism which is overcome by pulling on the handle of the probe, and another mechanism which requires an active release mechanism.

摘要： Methods of endoscopic surgery are disclosed. The methods utilize a suction/irrigation endoscopic instrument and a second endoscopic instrument. The suction/irrigation endoscopic instrument has a cannula, a fluid chamber in communication with the cannula, and an automatic valve at the proximal end of the fluid chamber. The second endoscopic instrument has end effectors and actuating means, and the end effectors of the second endoscopic instrument is inserted through the automatic valve, through the fluid chamber, and through the cannula. The methods involve inserting the suction/irrigation instrument through a trocar tube, and then inserting the second endoscopic instrument therethrough. The automatic valve insures that there is no leakage when the second instrument is inserted. The second endoscopic instrument may rotated inside, or may be partially withdrawn into the suction/irrigation instrument. Upon removing the second endoscopic instrument, the valve of the suction/irrigation instrument automatically closes so that there is no leakage. If desired, the suction/irrigation instrument may be provided with a cautery current at the cannula, and the second endoscopic instrument may be provided with a bump which contacts the cannula as a cautery pick-up.
