US Patent:

8449582, May 28, 2013

Filed:

Feb 28, 2007

Appl. No.:

11/711938

Inventors:

Robert F. McLain - Pepper Pike OH, US

Assignee:

The Cleveland Clinic Foundation - Cleveland OH

International Classification:

A61B 17/88

US Classification:

606281

Abstract:

In an exemplary embodiment of the present invention, a method of implanting a fusion plate, having at least two primary fastener openings, into a patient is described. According to the inventive method, a throat of the patient is dissected, providing access through the throat dissection to a spinal column of the patient. The fusion plate is inserted into the throat dissection, and the fusion plate is then positioned in an asymmetrical relationship with a sagittal plane of the spinal column. A first primary fastener is inserted through a first primary fastener opening of the fusion plate and into the first vertebra. A second primary fastener is inserted through a second primary fastener opening of the fusion plate and into the second vertebra. A cervical fusion apparatus is also disclosed.

International Classification:

A61B 10/00
A61B 17/56
A61B 17/58

US Classification:

600567, 606104, 606 73

Abstract:

An apparatus and method for use in aspirating bone marrow is provided. The apparatus comprises a tube which has a body with a distal end portion. The tube has a central opening at one end of a central passage extending through the tube and through which bone marrow is aspirated. The tube is also tapered. A thread convolution on the body of the tube at the distal end portion of the tube is also provided as an alternate design. At least one aspiration opening between the central opening and the thread convolution is used to further aspirate bone marrow.

Appl. No.:

5/433036

Inventors:

Robert E. McLain - Woodland Hills CA

Assignee:

Rockwell International Corporation - El Segundo CA

International Classification:

G01N 2900

US Classification:

73 678S

Abstract:

An ultrasonic inspection system is disclosed having a skate remotely controlled from a main console for positioning an ultrasonic transducer. A transmission line is used to couple drive pulses from the main control console to the transducer. Each drive pulse is generated at the console by timing means for firing a first silicon-controlled rectifier (SCR) to discharge a precharged capacitor into the line, and for firing a second SCR to shunt discharge current from the capacitor to ground. The line is terminated at its input end by its characteristic impedance. The length of the line may be changed without requiring any change at the transducer or the pulse generating circuit, except that the size of the precharged capacitor may be varied to assure delivery of a pulse of desired amplitude to the transducer.

Abstract:

A method and apparatus is disclosed for calibrating an ultrasonic inspection system having a plurality of transducers (12a, 12b, 12c) coupled by a common amplifier (16) to a distance-amplitude correction (D-AC) circuit comprised of a multiplying digital-to-analog converter (26') which receives, as a function of the transit time of an ultrasonic signal measured by a clock counter (34), a D-AC correction stored in a look-up table in a random access memory (24'). The D-AC correction function stored in the look-up table for each transducer is the inverse of a return signal response curve determined by measuring the peak amplitude of return signals from calibration holes at known depths in a test block (10) while in a calibrate mode, i. e. , with a switch (SW) in a state to bypass the MDAC. An equation of a curve that best fits the peak measurements is then found by a digital computer (20) and used to determine the values of points along a curve superimposed on the response curve, except at near field where the calibration system is provided with truncation for near-field effects.
