摘要:
An implantable electroacupuncture device (IEAD) treats hypertension through application of stimulation pulses applied at at least one of acupoints PC5, PC6, ST36, or ST37. The IEAD comprises an implantable, coin-sized, self-contained, leadless electroacupuncture device having at least two electrodes attached to an outside surface of its housing. The device generates stimulation pulses in accordance with a specified stimulation regimen. Power management circuitry within the device allows a primary battery, having a high internal impedance, to be used to power the device. The stimulation regimen generates stimulation pulses during a stimulation session of duration T3 minutes applied every T4 minutes. The duty cycle, or ratio T3/T4, is very low, no greater than 0.05. The low duty cycle and careful power management allow the IEAD to perform its intended function for several years.

摘要:
A cochlear lead includes a plurality of electrodes configured to stimulate an auditory nerve from within a cochlea and a flexible body supporting the plurality of electrodes along a length of the flexible body. A stiffening element is slidably encapsulated within the flexible body and positioned such that the stiffening element plastically deforms upon insertion into a curved portion of the cochlea.

Exemplary systems and methods for loading a pre-curved electrode array onto a straightening member are described herein. An exemplary system may include a loading tool including a housing and a slider member disposed at least partially within the housing. The slider member may be slidable from a first position to a second position and configured to move a pre-curved electrode array from a curved configuration to a straightened configuration as it slides from the first position to the second position. The exemplary system may also include a straightening member configured to be inserted into the pre-curved electrode array. Corresponding methods are also described.
摘要:
An intraneural implant comprises a lead comprising a number of electrode wires, a number of electrodes communicatively coupled to the electrode wires, the electrodes forming an electrode array, and an overmold surrounding the electrode wires and at least a portion of the electrodes, and a blunt dissector tip coupled to the lead to penetrate nerve tissues as the electrode array is implanted. An intraneural implant system comprises a flexible lead. The flexible lead comprises a lead body, an electrode array communicatively coupled to the lead body, a blunt dissector tip to penetrate a nerve bundle as the electrode array is implanted into the nerve bundle, and an implantation tool coupled to the electrode array to implant the electrode array into the nerve bundle.

摘要:
An impact resistant implantable antenna coil assembly comprising a flat antenna coil having a plurality of laterally separated turns of wire encapsulated with a non-orthogonal force absorbing coil reinforcement in a flexible biocompatible polymer and axially anchored with the reinforcement to a feedthrough case. Thus configured, non-orthogonal impact forces applied to the antenna coil assembly are absorbed and lateral components thereof that would otherwise be reflected as tensile forces in the plane of the coil are prevented from forming or from fracturing wire within the antenna coil.

A cochlear lead includes a plurality of electrodes configured to stimulate an auditory nerve from within a cochlea and a flexible body supporting the plurality of electrodes along a length of the flexible body. A stiffening element is slidably encapsulated within the flexible body, the stiffening element extending past a most distal electrode at the tip of the cochlear lead, wherein a distal portion of the stiffening element plastically deforms upon insertion into a curved portion of the cochlea.
