Patent ID: 7949395

Claim:
An implant assembly, comprising: a hypodermic needle; and an implantable device including: a microdevice containing electrical circuitry; a lead with a proximal end and a distal end, the proximal end of the lead being attached and electrically connected to the electrical circuitry of the microdevice; an electrode at the distal end of the lead, the electrode being electrically connected to the electrical circuitry of the microdevice via the lead; and anchors disposed at the distal end of the lead, wherein the anchors, when the implantable device is loaded within the hypodermic needle, are configured to fold back against an exterior of the hypodermic needle as the hypodermic needle is introduced into tissue, such that the anchors engage the tissue and affix the electrode relative to the tissue while the hypodermic needle is withdrawn from the tissue, wherein the anchors comprise non-insulated loose wire strands.
