82702 results about "Electrical conductor" patented technology

In physics and electrical engineering, a conductor is an object or type of material that allows the flow of charge (electrical current) in one or more directions. Materials made of metal are common electrical conductors. Electrical current is generated by the flow of negatively charged electrons, positively charged holes, and positive or negative ions in some cases.

Smart recognition apparatus and method

A qualifying connection for an instrument attaches to a source of electrosurgery energy to and the instrument and has first and second parts coupled to the instrument and the source, respectively. Optical couplings on the connection transmit invisible energy to identify the instrument and are proximate on the first and second parts. A light modifier on the first part is proximal to the second part for modification of radiation in the infrared wavelengths so infrared transmitters encode signals and non contact coded proximity detectors on the second part are the coupled detectors. Non contact coded proximity detectors respond to modified infrared light establishing an Nth bit identification code. An infrared light supply in the source pass from the transmitters across the communicating couplings for encoding signals by modification of the infrared light with a light modifier. Mechanical attachments include conjugating male and female portions physically extending between the parts for mating engagement. The attachments juxtaposition the parts when the attachments geometrically conjugate to geographically positioning the couplings proximate for communicating. The attachments have one or more conductors for delivery of high frequency energy from the source to the instrument. A cable fits between the first part of the connection and the instrument and has electrical conductors for carrying energy passing through the first part of the connection from the source to the instrument. An identifying circuit couples to the second part and responds to invisible light optically communicated across the couplings for verifying the type of instrument connected by the cable to the source.

Body implantable lead including one or more conductive polymer electrodes and methods for fabricating same

A body implantable lead comprises a lead body including a conductive polymer electrode disposed along a distal end portion of the lead body for performing one or more of the functions consisting of pacing, sensing, cardioversion and defibrillation. An electrical conductor, preferably in the form of a multistrand cable conductor, couples the conductive polymer electrode with a proximal end of the lead body. The conductive polymer electrode encapsulates the conductor and is in electrical contact therewith along the length, and preferably along substantially the entire length, of the conductive polymer electrode. The lead body may comprise a multilumen polymer housing, the conductor being contained within one of the lumens of the housing. The conductive polymer electrode may be disposed within a window formed in the lead body. Alternatively, the conductive polymer electrode may comprise multiple electrode sections within a corresponding number of windows formed in the lead body and spaced apart along the length thereof. Further, the window and the conductive polymer electrode disposed therein may extend helically about the lead body. Because of its flexibility and because it can have a small diameter, the lead of the invention is particularly advantageous for implantation in the small, tortuous vessels of the coronary sinus region of the heart for left side stimulation and/or sensing.
Methods of fabricating lead bodies incorporating conductive polymer electrodes are also disclosed.
