Publication number: 20130282000Abstract: A renal denervation device can include an elongated catheter body extending along a longitudinal axis, and an assembly connected to the catheter body. The assembly includes a plurality of heating elements connected to the catheter body. Each heating element has a conductor and a layer of an RF dissipating material such as a polymer overlying the conductor. During operation of the device, the layer of RF dissipating material is disposed between the conductor and body tissues of a subject. The layer of RF dissipating material is substantially thicker than the Debye length within the material in order to reduce the electric field reaching the tissue and to eliminate direct contact of the electrode with the body tissue.Type: ApplicationFiled: February 28, 2013Publication date: October 24, 2013Applicant: ST.

Patent number: 5666949Abstract: An exposure indicating apparatus and indicating method includes a sensor having a property responsive to a concentration of a target species. A processing device generates a concentration signal as a function of the property and an indicator is activated as a function of the concentration signal. The indicator is activated at a signaling rate indicative of an exposure indicating apparatus operating within predefined design parameters and at an exposure signaling rate indicative of the concentration attaining a predetermined threshold concentration. The indicator may also be activated at a signaling rate indicative of an exposure indicating apparatus operating outside of the predefined design parameters, and after the predetermined threshold concentration is attained, the indicator may be activated at an exposure signaling rate which varies as a function of the concentration signal.Type: GrantFiled: October 24, 1994Date of Patent: September 16, 1997Assignee: Minnesota Mining and Manufacturing CompanyInventors: Mark K.

Patent number: 5659296Abstract: An exposure indicating apparatus for monitoring air flowing along a flow-through path extending from the external environment through an air purifying respirator cartridge and into a face mask. A processor housing is releasably attached to the flow-through path so that it can be removed allowing ambient air to enter the flow-through path at the attachment location. A reversible sensor with at least one property responsive to a concentration of a target species within an environment is in fluid communication with the flow-through path. A processing device in the processor housing generates a concentration signal as a function of the at least one property of the reversible sensor. An indicator provides an active indication in response to the concentration signal. A flow-through housing may form a portion of the flow-through path. The flow-through housing may be interposed between the air purifying cartridge and the face mask.Type: GrantFiled: October 24, 1994Date of Patent: August 19, 1997Assignee: Minnesota Mining and Manufacturing CompanyInventors: Mark K.
