摘要： An apparatus includes a cannula with at least one wall portion having an electrically insulating material. The at least one wall portion at least partially bounds a region configured to contain a portion of a medical implant system configured to be implanted on or within a recipient. The cannula further includes at least one portion configured to provide at least one electrically conductive pathway through the at least one wall portion from within the cannula to a region outside the cannula.

摘要： A method includes providing an electrode configured to be implanted within a body portion of a recipient in tissue at a target implantation location, the electrode comprising a screw portion. The method further includes driving the screw portion into the tissue at the target implantation location, monitoring at least one signal indicative of insertion of the screw portion into the tissue, and stopping the driving in response to the at least one signal being indicative of a predetermined insertion of the screw portion.

摘要： Presented herein are dual-function surgical tools for insertion of implantable stimulating assemblies, such as intra-cochlear stimulating assemblies. In addition to facilitating intra-operative positioning of a stimulating assembly within a recipient (e.g., operating to guide the stimulating assembly of an implantable medical device into position), the surgical tool also includes a plurality of electrodes configured to apply an electroporation electrical field to a recipient's nerve cells to enable introduction of treatment substance into the nerve cells.

摘要： Presented herein are integrated tube sheaths (tube sheaths) for implantable stimulation assemblies. An integrated tube sheath is configured to be disposed around, and is slideably engaged with, an outer surface of an associated stimulation assembly. The integrated tube sheath is configured to retain the stimulation assembly in a straight arrangement for implantation of the stimulation assembly into a recipient. Following implantation of the stimulation assembly, the integrated tube sheath is configured to remain implanted in the recipient.

摘要： Presented herein are trans-modiolar stimulation techniques in which stimulation current is sourced (delivered) by at least one intra-cochlear stimulating contact and is sunk at a group of other intra-cochlear stimulating contacts. The group of other intra-cochlear stimulating contacts is positioned (located) across a section of the recipient's modiolus from the intra-cochlear stimulating contact that sources the stimulation. As such, stimulation current generally passes through the modiolus to stimulate spiral ganglion cells and evoke a hearing percept.
摘要翻译： 这里提出的是反式模式刺激技术，其中通过至少一个耳蜗内刺激接触来源（递送）刺激电流并且沉没在一组其他耳蜗内刺激接触处。 其他耳蜗内刺激接触的组被定位（定位）穿过来自刺激的耳蜗内刺激接触的接受者的一部分。 因此，刺激电流通常通过脉络膜刺激螺旋神经节细胞并引起听觉感知。
