摘要:
A steerable member is disclosed generally having a steerable member for a medical apparatus, including a continuous, elongated body having a proximal section, a distal section, and a middle section between the proximal and distal sections, where the proximal section of the elongated body is less flexible than the distal section. At least one pull wire sheath extends through the proximal section and the middle section, but not through the distal section, and has a channel therethrough. A pull wire is disposed in the channel of the sheath and extends through the proximal section, middle section and distal section of the elongated body, the pull wire having a distal end affixed to a distal end of the elongated body, so that the distal section of the elongated body bends in response to a force applied to the proximal end of the pull wire.

摘要:
An electrosurgical probe having a plenum which prevents contact of the active electrode with tissue, while simultaneously allowing a fluid/interfacing agents to contact the active electrode.
摘要:
The effects produced by surgical devices that deploy an electrical circuit between electrodes are dependent on the nature of electrical work perform upon the conductive media in an around biologic tissues. Non-ablation radiofrequency surgical devices utilize a protective housing that provides, based upon procedure-specific needs, the ability to 1. move, manipulate, and segregate near-field effects both tangentially and perpendicularly to the tissue surface, 2. deliver far-field electromagnetic effects to tissue unencumbered by current deposition, and 3. serve as a 20 mechanical adjunct to and a selective throttling vent/plenum for energy delivery. Because the electrodes are non-tissue-contacting, this study characterizes the effects that non-ablation radiofrequency energy exerts upon interfacing media typically encountered during surgical applications. These devices create a Repetitive Molecular Energy Conversion Loop for surgical work; and, non-ionizing electromagnetic forces are deployed in strength levels that can produce thermal and non-thermal biologic tissue effects. A differential between current density dispersion and electromagnetic field strength is exploited to allow normal tissue healing responses to the near-field effects of tissue modification and preconditioning while permitting far-field effects, which are useful for inducing therapeutic biologic responses, to manifest in treated tissues that have been protected from electrical current generated collateral damage.
摘要:
Devices for electrosurgery by means of oxy-hydro combustion and methods for use of such devices in electrosurgical procedures. Provided are devices for combustion of oxygen and hydrogen, or other hydrocarbon fuels, wherein oxygen and hydrogen may be generated by electrolysis or oxygen and hydrogen, or other hydrocarbon fuels, may be supplied, such devices including an ignition source and an adjustable and translatable sheath for controlling such reactions. Also provided is a detachable and positionable sheath for controlling reactions and minimizing tissue damage with conventional electrosurgery devices.
