Patent number: 8838214Abstract: Systems and methods are provided herein that generally involve measuring a prostate or other object. In some embodiments, a membrane can be sealed over a digit extension to form a closed volume. The closed volume can be inflated via an inflation tube, and a reference pattern can be disposed within the closed volume along with a measurement assembly. In use, a user can put on the glove, position the membrane in proximity to a rectal wall overlying a prostate, and inflate the membrane. As the user slides their finger across the rectal wall, optical fibers in the measurement assembly can move relative to a reference pattern, and a controller can sense light reflected through the fibers from the reference pattern. The controller can calculate or estimate various attributes of the prostate based on the reflected light, such as the palpable surface width or volume.Type: GrantFiled: October 30, 2012Date of Patent: September 16, 2014Assignee: MedicaMetrix, Inc.Inventor: Christopher LaFarge

Patent number: 7878989Abstract: A total knee prosthesis comprises a femoral component and a patellar component. The femoral component has a patellar flange into which is built a twist or roller coaster configuration. The patellar component has an off-set dome with respective lateral and medial facets. The configuration of the patellar flange resists forces from a medial to a lateral direction, whilst the lateral and medial facets of the patellar component are respectively shaped to allow area contact and line contact respectively with the femoral component. Also disclosed is a device for intra-operative checking of patellar tracking to allow correct insertion of the femoral and patellar components.Type: GrantFiled: December 27, 2006Date of Patent: February 1, 2011Inventor: Derek James Wallace McMinn

Patent number: 7848787Abstract: A method for calibrating impedance includes coupling at least first, second, and third electrodes at respective locations to a surface of a body of a subject. A first current passing through the body between the first and second body-surface electrodes is measured, and a second current passing through the body between the first and third body-surface electrodes is measured. From the first and second currents, a contact factor is derived that is indicative of the impedance between at least one of the body-surface electrodes and the surface of the body. Also described are methods for sensing the position of a probe and for detecting tissue contact based on a relation between currents from the probe to body-surface electrodes.Type: GrantFiled: July 8, 2005Date of Patent: December 7, 2010Assignee: Biosense Webster, Inc.Inventor: Daniel Osadchy

Patent number: 7708751Abstract: A localization mechanism, or fixture, is used in conjunction with a breast coil for breast compression and for guiding a core biopsy instrument during prone biopsy procedures in both open and closed Magnetic Resonance Imaging (MRI) machines. The localization fixture includes a three-dimensional Cartesian positionable guide for supporting and orienting an MRI-compatible biopsy instrument, and in particular a sleeve, to a biopsy site of suspicious tissues or lesions. A depth stop enhances accurate insertion, prevents over-insertion or inadvertent retraction of the sleeve. The sleeve receives a probe of the MRI-compatible biopsy instrument and may contain various features to enhance its imagability, to enhance vacuum and pressure assist therethrough, etc.Type: GrantFiled: March 10, 2005Date of Patent: May 4, 2010Assignee: Ethicon Endo-Surgery, Inc.Inventors: Robert J.

Publication number: 20090012418Abstract: A magnetic detector locates magnetically tagged items, such as surgical sponges or instruments, introduced to and remaining in the body cavity of a surgical patient. The magnetic detector is a wand or probe that is manually handleable, and spatially manipulable and moveable, by an operator, such as a medical professional. The detector is moved about at a spatial location of an ambient magnetic field at the patient and operating table. A characteristic of the ambient magnetic field at the spatial location is saved by the detector. The detector is subsequently moved about at the same spatial location. If any magnetically tagged item is present in the vicinity of the detector during this subsequent movement at the spatial location, an anomalous magnetic effect is detected by comparison of the prior detection reading absent the tagged item to the detection reading in presence of the tagged item in the patient.Type: ApplicationFiled: July 3, 2007Publication date: January 8, 2009Inventor: Frank Gerlach

Patent number: 7309319Abstract: A method and system for measuring the dimensions of the palpable surface of the prostate in the physician's office and calculating prostate volume, rate of growth and changes in rate of growth. A membrane with a grid pattern is located proximate the prostate. A physician moves a measurement system, formed at the end of the index finger and located in a glove, between opposite margins of the prostate. The measurement system counts the grid elements between the margins that translate into a quantitative measurement of size of the palpable surface of the prostate.Type: GrantFiled: November 24, 2004Date of Patent: December 18, 2007Assignee: Sensors for Medicine, Inc.Inventors: Ian Peter Kellett, John R.
