METHOD FOR IMPLANTING AN IMPLANTABLE DEVICE IN BODY TISSUE

摘要

An implantable device for body tissue, including an electrical subsystem that flexes within and interfaces with body tissue and a carrier that operates in the following two modes: provides structural support for the electrical subsystem during implantation of the device in body tissue and allows flexing of the electrical subsystem after implantation of the device in body tissue. The implantable device is preferably designed to be implanted into the brain, spinal cord, peripheral nerve, muscle, or any other suitable anatomical location. The implantable device, however, may be alternatively used in any suitable environment and for any suitable reason.

主权项

1. A method for implanting and using a neural interface device, comprising the steps of:
a) providing a neural interface device, comprising:
i) a carrier extending along a first carrier length from a proximal carrier portion to a distal carrier portion having a distal carrier end, wherein the carrier is of a bioresorbable material that is absorbable into body tissue after implantation;ii) a first electrical subsystem, comprising:
A) at least one electrode site configured to interface with neural tissue; andB) an electrode substrate supporting the at least one electrode site; andiii) an electrical connector extending from the at least one electrode site to a proximal connector portion adjacent to the proximal carrier portion,iv) wherein at least a portion of the electrode substrate is woven with the carrier so that the at least one electrode site has an exposed surface facing outwardly from the electrode substrate opposite the carrier; b) implanting the neural interface device comprising the carrier, the first electrical subsystem, and the electrical, connector into body tissue; and c) permitting the neural interface device to remain implanted for a sufficient amount of time so that the carrier is absorbed. into the body tissue, thereby leaving the at least one electrode site facing outwardly toward the body tissue from the supporting electrode substrate.
