This invention relates to the construction of a cardiac ablation electrode with a thermosensing detector at one or more positions in the distal tip. The distal tip is uninsulated in contrast to the rest of the flexible length of the electrode to enable radiofrequency (rf) potential to be applied the ...
An expandable atherectomy cutting device comprises a flexible blade having one end connected to a torque tube and the other end connected to a tip. The tip and torque tube are rotatably positioned about a guide wire, and the torque tube is coupled to a drive element for rotating the flexible blade a ...
A method and apparatus for verifying the proper airing of television program having a digital identification code recorded on a preselected scan line which is not normally visible to the television viewer. A plurality of television channels are automatically simultaneously monitored by a primary mon ...
The invention is a method for preparing a plurality of light emitting diodes on a single substrate of a semiconductor material. The method is used for structures where the substrate includes an epitaxial layer of the same semiconductor material that in turn comprises layers of p-type and n-type mate ...
A mass localization device includes a catheter and a needle. The catheter includes inner and outer walls spaced from each other and creating a gap between the walls extending along substantially the entire length of the catheter. The distal portion of the outer wall includes an inflatable balloon. A ...
A method of making an integrated, microminiature, electric-to-fluidic valve. The method comprises, in one embodiment, anisotropically etching a cavity in a silicon wafer to form a thin membrane at the bottom of a trench. Then a second wafer is etched to form an exit path surrounded by a valve seat p ...
An extendable guidewire system for introducing a dilatation catheter into the arterial system of a patient. The guidewire system has guidewire and extension sections with a connection therebetween which permits the two sections to be joined together and separated simply by twisting the two sections ...
To accurately shade headlamp light for both a leading vehicle running on the same lane and an opposed vehicle running on an opposed lane, the headlight apparatus for an automotive vehicle comprises a movable headlamp, a light sensor attached on the pivotal headlamp for detecting presence of a leadin ...
An adaptive processing system for real-time signal processing of one or more input signals in parallel-pipeline fashion is provided. According to the invention, the adaptive processing system includes a random access processor having an array of processing elements each being individually configurab ...
A method for surgically securing body parts with a cable, typically making use of crimping pliers which comprise a pair of operating handles and connected, opposed jaws. The jaws define opposed recesses for carrying and crimping a tubular crimp member by manual pressure on the operating handles. A c ...
