Appl. No.:

11/323610

Inventors:

Jason T. Sherman - Leesburg IN, US

International Classification:

G01R 33/02
G01B 7/14

US Classification:

324247, 324258, 32420713

Abstract:

A magnetic sensor array includes a first three-dimensional magnetic sensor secured to a substrate in a central location of the substrate. A number of second three-dimensional magnetic sensors are secured to the substrate at a first distance from the first magnetic sensor. Additionally, a number of one-dimensional magnetic sensors are secured to the substrate at a second distance from the first magnetic sensor greater than the first distance. Additional magnetic sensors of any dimension may also be included. The magnetic field sensitivity of the first and second three-dimensional magnetic sensors may be less than the magnetic field sensitivity of the one-dimensional magnetic sensors. The sensing range of the first and second three-dimensional magnetic sensors may be greater than the sensing range of the one-dimensional magnetic sensors. The magnetic sensor array may also include a processing circuit coupled to the magnetic sensors.

International Classification:

G01C 3/08

US Classification:

436 2, 73587, 73589, 7386123, 264407, 264411

Abstract:

A system and method for determining the operating state of a curable composition utilizes an acoustic wave or signal transmitted into a container holding the composition. In one embodiment, characteristics of a reflected component of the acoustic signal are measured and correlated to pre-determined values indicative of one or more operating states, or degrees of curing, of the composition. In another embodiment, characteristics of a transmitted component of the acoustic signal are measured and correlated. The characteristics include, for example, the speed of sound through the curable composition or the attenuation of the acoustic signal reflected by or transmitted through the composition.

US Classification:

623 1811, 623 1812, 600587, 128903

Abstract:

An orthopaedic element has an information storage portion. A transmitter portion and an internal power source portion may be associated with the body of the orthopaedic element. Information, such as data related to the orthopaedic element, patient or caregiver can be stored in the information storage portion. The transmitter portion is coupled to the information storage portion and the internal power source portion. The stored information is selectively transmitted to an external receiver and data interpretation device.

Abstract:

A system, apparatus, and method for determining a position of an orthopaedic prosthesis includes a patient support platform, a sensor array coupled to the patient support platform, and a controller electrically coupled to the sensor array. The sensor array is configured to generate data signals in response to an output signal of a signal source(s) coupled to the orthopaedic prosthesis and/or a bone of the patient. The controller is configured to determine a position of the orthopaedic prosthesis and/or the bone of the patient based on the data signals.

Inventors:

Jason Sherman - Warsaw IN, US

Assignee:

DePuy Products, Inc. - Warsaw IN

International Classification:

A61F 5/00

US Classification:

602 20, 602 23

Abstract:

An apparatus for transcutaneously transferring an amount of energy to an implantable orthopaedic device includes a primary coil. The primary coil has a resonant frequency matched to a resonant frequency of a secondary coil, which may form part of the implantable orthopaedic device. The primary coil may have an aperture configured to receive a portion of a patient's body or may include a substantially “C”-shaped core. A power circuit may be coupled with the primary coil to provide power to the coil. The apparatus may also include a wireless receiver, a measuring device, and/or a display.

Abstract:

A system that enables targeting of an instrument placed within a drill bushing aligns the axis of a drill bushing with the axis of a transverse hole in an intramedullary nail. The system includes a probe having an elongated member with a distal end, a magnet that is polarized along its longitudinal axis that is mounted perpendicularly to the distal end of the elongated member; and a processor executing programmed instructions to determine a position and orientation of the magnetic sensor array with respect to the targeting magnet.
