Patent number: 11135430Abstract: An apparatus associated with a cochlear implant system used by a patient directs a cochlear implant included within the cochlear implant system and implanted within the patient to generate electrical stimulation current at a predetermined current level. The apparatus further directs the cochlear implant to apply the electrical stimulation current to the patient by way of an electrode coupled with the cochlear implant, and to measure a voltage level associated with the electrode while the electrical stimulation current is applied to the patient by way of the electrode. Based on the predetermined current level and the measured voltage level, the apparatus determines an impedance of the electrode. Based on the determined electrode impedance and in accordance with a predetermined stimulation parameter adjustment constraint, the apparatus automatically adjusts a stimulation parameter associated with the cochlear implant system. Additional apparatuses and corresponding methods are also disclosed.Type: GrantFiled: February 22, 2018Date of Patent: October 5, 2021Assignee: Advanced Bionics AGInventors: Roger Calixto, Kanthaiah Koka, Anthony J. Spahr, Mary Elizabeth Bush, Mark B. Downing, Leonid M. Litvak, Amy Stein

Patent number: 9669113Abstract: Cavity and sentinel lymph node marking devices, marker delivery devices, and methods are disclosed. More particularly, upon insertion into a body, the cavity marking device and method enable one to determine the center, orientation, and periphery of the cavity by radiographic, mammography, echogenic, or other noninvasive imaging techniques. A composition and method are disclosed for locating the sentinel lymph node in a mammalian body to determine if cancerous cells have spread thereto. The composition is preferably a fluid composition consisting of a carrier fluid and some type of contrast agent; alternatively, the contrast agent may itself be a fluid and therefore not need a separate carrier fluid. This composition is capable of (1) deposition in or around a lesion and migration to and accumulation in the associated sentinel node, and (2) remote detection via any number of noninvasive techniques.Type: GrantFiled: December 23, 1999Date of Patent: June 6, 2017Assignee: DEVICOR MEDICAL PRODUCTS, INC.Inventors: D. Laksen Sirimanne, Natalie V. Fawzi, Douglas S. Sutton, Gail S. Lebovic, Stanley R. Conston, Peter M. Wilson, Anne B. Morrissey, Mary Elizabeth Bush

Patent number: 9108043Abstract: An implantable active fixation lead includes an outer sheath, a protector member having a peripheral surface extending between its distal and proximal end surfaces with a helical groove formed in the peripheral surface, and a fixation helix integral with the outer sheath. The fixation helix includes a tip end engageable with body tissue and slidably engaged with the helical groove for relative translation and rotation. A longitudinal force on the lead firmly engages the protector member's distal end surface with the body tissue. With the fixation helix initially retracted proximally of the protector member's distal end surface and disengaged from the body tissue, upon application of torque to the outer sheath, the distal end surface of the protector member is moved proximally with respect to the fixation helix which, simultaneously, is extended distally beyond the distal end surface of the protector member to an extended position into engagement with the body tissue.Type: GrantFiled: October 15, 2010Date of Patent: August 18, 2015Assignee: PACESETTER, INC.Inventors: Mary Elizabeth Bush, Rolf Hill, Steven R.

Publication number: 20130066195Abstract: A subcutaneous cavity marking device percutaneously implantable in breast tissue during a biopsy procedure. The marking device including at least two implantable bodies, one made from a first material and another made from a second material wherein the first and second materials are different materials and the at least two implantable bodies are adapted to be inserted into a subcutaneous cavity created by removal of tissue. The at least two implantable bodies are detectable via non-invasive techniques as tissue cavity markers and at least one of the at least two detectable bodies is an electronic chip connected to the other of the at least two implantable bodies.Type: ApplicationFiled: September 5, 2012Publication date: March 14, 2013Inventors: D.

Patent number: 8214033Abstract: Exemplary systems, devices, and methods pertaining to cardiac related therapy and particularly to interferential cardiac preconditioning and depolarization are described. A cardiac arrhythmia is detected from electrogram data sensed from a patient's heart and a region of the heart affected by the cardiac arrhythmia is determined. The affected region is interferentially energized by multiple cycles of two concurrently delivered alternating currents which are offset in frequency.Type: GrantFiled: November 5, 2008Date of Patent: July 3, 2012Assignee: Pacesetter, Inc.Inventors: Jay Snell, Mary Elizabeth Bush

Patent number: 6363288Abstract: A system for providing medical electrical stimulation includes a pulse generator coupled to a lead having two electrodes for placement in the right atrium or for placement of one in the right atrium and one in the coronary sinus or coronary vein. In the preferred embodiment the surface area of the first electrode is smaller than that of the second electrode so that the sensed signal from the first electrode is less than that from the second. The system provides dual site pacing with essentially single site sensing without the use of extra switches, connectors, or adaptors.Type: GrantFiled: August 20, 1999Date of Patent: March 26, 2002Assignee: Pacesetter, Inc.Inventors: Mary Elizabeth Bush, Mae-Mae Shieh
