Electromagnetic Apparatus And Method For Nerve Localization During Spinal Surgery
US Patent:
2008008, Apr 10, 2008
Filed:
Aug 28, 2007
Appl. No.:
11/897169
Inventors:
Erich Wolf - Lake Charles LA, US
International Classification:
A61B 17/00, A61B 18/04
US Classification:
606 79, 606 33, 606 39
Abstract:
An electromagnetic pedicle awl utilizes a tightly focused time-varying magnetic flux to create a localized electromotive force (EMF) near the tip of a pedicle awl. The localized EMF creates localized eddy currents in nearby nerves which in turn excite ionic nerve channels, the excitation being detected by an electromyographic recording device. In comparison to the electrically stimulated pedicle awl of the prior art, the electromagnetic pedicle awl only excites nerves directly in front of and directly to the side of the tip. The electromagnetic pedicle awl is comprised of a tapered awl or drill tip in combination with a solid core surrounded by a solenoid. A pulsed electric current source drives the solenoid to create a time-varying magnetic field in the vicinity of the tapered tip. The awl or drill tip may be stationary with respect to the solenoid or it may rotate. The electromagnetic pedicle awl in combination with an EMG detector connected to a patient is very sensitive to the pedicle hole position with respect to adjacent nerves and reduces false placement failure.
System For Transcutaneous Monitoring Of Intracranial Pressure
US Patent:
8057401, Nov 15, 2011
Filed:
Oct 6, 2006
Appl. No.:
11/544849
Inventors:
Erich Wolf - Lake Charles LA, US
International Classification:
A61B 5/00
US Classification:
600561, 600309, 600486, 73722
Abstract:
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. Alternately, a set of tuned inductor-crystal circuits versus inductor-crystal comprised in part of a cylindrical crystal oscillator whose resonant frequency is sensed by a dipper circuit arrangement is provided. 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. A computer within the processing and display module calculates the parameter value from the telemetry signal and represents this data either in numerical, graphical, or analog format.
Transcutaneous Telemetry Of Cerebrospinal Fluid Shunt Programmable-Valve Pressure Using Near-Infrared (Nir) Light
US Patent:
7485105, Feb 3, 2009
Filed:
Feb 25, 2005
Appl. No.:
11/067497
Inventors:
Erich W. Wolf - Lake Charles LA, US
International Classification:
A61M 5/00, A61M 37/00, F16K 31/02
US Classification:
604 9, 604 61, 25112911
Abstract:
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.

Pda Compatible Text Scanner
US Patent:
8235291, Aug 7, 2012
Filed:
Dec 16, 2010
Appl. No.:
12/928665
Inventors:
Erich Wolf - Lake Charles LA, US
International Classification:
G06K 7/10
US Classification:
235454, 235473
Abstract:
An optical text scanning device compatible with a small handheld computer such as a personal digital assistant (PDA). The scanning device allows for a clear view of the text that is scanned simultaneous to the scanning process so that the operator can continuously align the device to the text. The scanned images of the text are converted in real-time to standard byte or word characters for subsequent display on the computer's viewing screen. The operator can quickly verify the accuracy of the conversion by comparing the displayed character with the actual character of text on the surface that is being scanned. Scanned text characters are stored in standard digital text files for ease of manipulation.
