Publication number: 20060266366Abstract: The present invention is a system comprising an illumination means and is mounted on a catheter wherein said illumination is generally located in the distal end of the catheter. Locating the illumination means near the distal end will simplify and facilitate precise placement of a measurement device in close proximity to the desired location. In one example, a catheter with a distally mounted pH sensor benefits from the use of an illumination means in the patient's airway such as in the oropharynx region. The illumination source of the present invention addresses catheter insertion and location using a continuous or flashing light emitting diode (LED) embedded in the distal end of the catheter to provide a visual sighting means for the physician.Type: ApplicationFiled: May 25, 2005Publication date: November 30, 2006Inventors: Ross Tsukashima, Erich Wolf, Jeffery Schipper, Charles Bankert, Leo Roucher

Publication number: 20060270936Abstract: The present invention pertains to an apparatus for evaluating the signal strength from the pH sensor to determine whether the sensor is hydrated sufficiently to accurately measure pH. This is accomplished by utilizing circuitry that periodically sends a low voltage signal to a suitable pH sensor and then receiving the resulting waveforms which are analyzed by a processing receiver. The electrical connection between a suitable pH sensor and hydration monitoring circuitry is generally hard wired. In one embodiment, a processing receiver is coupled with the hydration monitoring circuitry as a single apparatus. In a second embodiment, the processing receiver can be independent and located remote from the hydration monitoring circuitry. In this embodiment, the hydration monitoring circuitry and the processing receiver are electrically connected using either hard wired techniques or wireless technology. In addition, the processing receiver can include data recording capability.Type: ApplicationFiled: May 25, 2005Publication date: November 30, 2006Inventors: Ross Tsukashima, Erich Wolf, Jeffery Schipper, Charles Bankert, Leo Roucher, Thomas Wallner

Publication number: 20050187488Abstract: A system for measuring and converting to an observer intelligible form an internal physiological parameter of a medical patient. The invention allows transcutaneous telemetry of the measured information intracranial pressure via a system which includes a patient implanted sensor module and a processing and display module which is external of the patient and optically coupled to the sensor module via an external coupling module. A sensor within the implanted module transduces the measured information and a near infrared (NIR) emitter transmits this telemetry information when interrogated by the complementary external coupling module. Power for the sensor module is derived inductively through rectification of a transcutaneously-applied high-frequency alternating electromagnetic field which is generated by a power source within the external coupling module, in concept much like a conventional electrical transformer.Type: ApplicationFiled: February 24, 2005Publication date: August 25, 2005Inventor: Erich Wolf

Publication number: 20050187509Abstract: An improvement for a programmable valve system of the type which is implanted in a medical patient and used to divert cerebrospinal fluid (CSF) from an intraventricular space of the patient to a terminus such as the patient peritoneal cavity. Such system includes means for establishing a flow path for the CSF to the terminus, which flow path includes a normally closed valve and means for adjusting the opening pressure of the valve in order to regulate the quantity of CSF diverted. The improvement enables an operator to be apprised of the actual opening pressure setting of the valve. A sensor is implantable at the patient and responds to the actual opening pressure setting, by generating an NIR telemetry signal indicative of the actual setting. This signal is transcutaneously transmitted through the skin of the patient to an external point. The telemetry signal is processed to produce observer intelligible data indicating the opening pressure setting of the valve.Type: ApplicationFiled: February 25, 2005Publication date: August 25, 2005Inventor: Erich Wolf

Patent number: 6354845Abstract: An apparatus for connecting a plurality of electrical circuits borne upon a plurality of substrates is disclosed. A first substrate of the plurality of substrates has a first aperture having a first diametral displacement and a first inner wall. A portion of the first inner wall is electrically connected with a first circuit borne upon the first substrate. The apparatus comprises a sheet of electrically conductive material arranged to a displacement from an axis in a substantially helical orientation about the axis. The material has a spring characteristic when the helical orientation establishes the displacement at a spring displacement. The spring characteristic urges the conductive material to a greater displacement from the axis than the spring displacement and permits insertion of the apparatus in the first aperture. The spring characteristic and the first diametral dimension cooperate to seat the apparatus in the first aperture to establish electrical connection with the first circuit.Type: GrantFiled: June 1, 2000Date of Patent: March 12, 2002Assignee: Lucent Technologies Inc.Inventors: Karl Erich Wolf, William Lonzo Woods, Jr.
