Abstract: A short backloading wire is provided to facilitate the backloading of a catheter onto a guidewire that has a tubular connector. This backloading wire is preferably shorter than the guidewire and at least one end is engageable with the hypotube connector at the proximal end of many guidewires. The free end of the backloading wire has a reduced diameter making easier to insert into the distal tip of a catheter during backloading.

Abstract: A radio-frequency ablation system is disclosed in which the power, voltage, or temperature delivered to multiple electrodes may be dynamically controlled, and in which the electrodes may be simultaneously energized in phase with each other to achieve a desired lesion pattern. The system comprises a multiple electrode ablation catheter, each electrode having a temperature sensor operatively associated therewith. Each electrode is energized by its own RF amplifier, and all of the electrodes are driven in phase with each other by a common sine wave oscillator. A feedback network controls the degree of amplification of the separate RF amplifiers. According to a further aspect of the invention, a modular power supply arrangement is disclosed which is configurable to dynamically control the power, voltage, or temperature delivered to multiple electrodes of a multipolar ablation device. An arbitrary number of electrodes may be simultaneously energized in phase with each other to achieve a desired lesion pattern using the modular power supply by providing a sufficient number of removable modules.

Abstract: A guidewire for use with a catheter has varying radiopacity as well as at least one radiopaque marker in its distal end. In one embodiment, the guidewire includes a shaft having a distal radiopaque coil supported by and attached to a distal portion of the shaft and a proximal radiopaque coil supported by and attached to an intermediate portion of the shaft. The proximal and distal coils are spaced apart from one another. The distal coil may be more radiopaque than or equally radiopaque to the proximal coil such that when viewed under fluoroscopy, the highly radiopaque coil will define a dark image whereas the more proximal radiopaque coil will define a moderately radiopaque image or both will define a dark image. The area between the two coils will appear white. Between the coils, at least one radiopaque marker band is attached to the shaft. The marker bands provide several reference lengths for a physician. A polymer sleeve encases the marker bands and the shaft between the first and second coils providing a uniform outer diameter to the distal region of the guidewire. In another embodiment, the proximal coil of the first embodiment is absent and the polymer sleeve extends proximally of the radiopaque marker bands. In a further embodiment, a radiopaque coil having varying pitch along its length is supported by and attached to a distal region of the core wire.

Abstract: An angioplasty system and method for identification and laser ablation of atherosclerotic plaque at a target site in a blood vessel includes fluorescence analysis for identification of noncalcified plaque and calcium photoemission analysis for identification of calcified plaque. Calcified plaque is identified by time domain analysis of calcium photoemission. A high energy pulsed ultraviolet laser can be used for stimulation of fluorescence and for stimulation of calcium photoemission. The system is capable of distinguishing between calcium photoemission and a defective condition of optical fibers that are used to deliver laser energy to the target site. In another embodiment of the angioplasty system, calcium photoemissionis identified during a nonablative initial portion of the laser ablation pulse. When calcium photoemission is not identified, the laser ablation pulse is terminated during the initial nonablative portion thereof.
