    • An implantable stimulator includes a tube assembly that is configured to house a number of components that are configured to apply at least one stimulus to at least one stimulation site within a patient. The tube assembly has a shape that allows the stimulator to be implanted within said patient in a pre-determined orientation. Exemplary methods of stimulating a stimulation site within a patient include applying an electrical stimulation current to a stimulation site via one or more electrodes extending along one or more sides of a stimulator. The stimulator has a shape allowing the stimulator to be implanted within the patient in a pre-determined orientation.

    • A hybrid cochlear implant hearing aid sytem (10) provides low frequency acoustic energy boost, if needed, and high frequency direct neural stimulation. Tinnitus suppression may also be provided. The neurons responsible for sensing high frequency sounds are located at the basal end of the cochlea. A short basal electrode (52) that extends into the cochlea only at the basal region allows direct stimulation of these neurons by an appropriately-controlled cochlear stimulator (50). The basal electrode array typically has from four to eight electrode contacts (54). The design of the electrode array allows the surgeon to place the array using minimally invasive surgical techniques and requires no cochleostomy. The electrode array is thin, and can typically be inserted directly through the round window membrane to make contact with, or to be positioned in close proximity to, the modiolus wall in the basal region of the cochlea. The hybrid implantable cochlear stimulator and hearing aid system relies primarily on the cochlear stimulator portion of the system for being able to sense high frequency sounds, and relies primarily on normal hearing processes, or other acoustic boosting devices and systems, for being able to sense lower frequency sounds.
    • 混合耳蜗植入式助听器系统(10)提供低频声能增强,如果需要,以及高频直接神经刺激。 也可以提供耳鸣抑制。 负责感测高频声音的神经元位于耳蜗的基端。 仅在基底区域延伸到耳蜗的短基底电极(52)允许通过适当控制的耳蜗刺激器(50)直接刺激这些神经元。 基极电极阵列通常具有四至八个电极触点(54)。 电极阵列的设计允许外科医生使用微创手术技术来放置阵列,并且不需要耳蜗造口术。 电极阵列是薄的,并且通常可以直接插入通过圆窗膜以与耳蜗的基底区域中的闭孔壁接触或靠近位置。 混合植入式耳蜗刺激器和助听器系统主要依赖于系统的人工耳蜗刺激器部分,以便能够感测高频声音,并且主要依赖于正常听力过程或其他声学增强装置和系统,以便能够感测较低频 频率声音。

    • Embodiments of implantable infusion pumps are provided that use a process of converting a first substance to a second gaseous substance (e.g. by electrolysis) to provide a motivating force to expel a desired fluid (e.g. drug or medication) from the pump into the body of a patient. An expandable sack may be provided around a gas producing electrolytic cell, such that as the gas expands it displaces a portion of the volume originally allocated to the desired fluid, and thereby forces the fluid from the pump. Pumps may be provided with a double septum to allow refilling of the desired fluid while simultaneously allowing removal of the generated gas from the system while using a single needle. Recharging of pump batteries may occur by direct electrical conduction through one or more needles and/or by r.f. energy transfer. Programming of the pump may occur by way of conductive paths provided by one or more needles or by means of r.f. transfer. A pressure regulator may be provided in vicinity to an outlet port of the pump so as to enable more reliable operation of the pump when subjected to changes in ambient pressure. A one-way valve may also be provided to reduce risk of back flow into the pump.

    • An inflatable cochlear electrode array adapted for insertion into a human cochlear includes a flexible carrier on which a multiplicity of spaced-apart electrode contacts are carried, preferably along one side, e.g., a medial side, of the carrier. The flexible carrier also includes an inflatable compartment or section. In one embodiment, the inflatable section is located at the distal tip of the electrode array on a side of the flexible carrier that is opposite the electrode contacts. In another embodiment, the inflatable compartment or section is located along at least one half of the full length of the flexible carrier, forming a spine. In either embodiment, the electrode is readily inserted into the cochlea to a desired depth while the inflatable compartment or section remains in a deflated state. Thereafter, a desired modiolus-hugging position is achieved by inflating the inflatable compartment or section by injecting therein a suitable biocompatible fluid. A method of making an inflatable cochlear electrode is also disclosed.
