US Patent:

7840283, Nov 23, 2010

Filed:

Sep 21, 2006

Appl. No.:

11/534153

Inventors:

Mary Elizabeth Bush - Santa Clarita CA, US
Rolf Hill - Jarfalla, SE
Steven R. Conger - Agua Dulce CA, US
Olof Stegfeldt - Alta, SE

Assignee:

Pacesetter, Inc. - Sylmar CA

International Classification:

A61N 1/05

US Classification:

607127

Abstract:

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.

Jay Snell - Studio City CA, US
Mary Elizabeth Bush - Santa Clarita CA, US

Assignee:

Pacesetter, Inc. - Sylmar CA

International Classification:

A61N 1/00

US Classification:

607 5, 607 28, 607 67

Abstract:

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.

International Classification:

A61N 1/36
A61N 1/05

Abstract:

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.
