Abstract: Methods, systems, and compositions are provided for implanting an implantable device into a biological tissue (e.g., muscle, brain). A subject implantable device includes: (i) a biocompatible substrate, (ii) a conduit (e.g., an electrode, a waveguide) that is disposed on the biocompatible substrate, and (iii) an engagement feature (e.g., a loop) for reversible engagement with an insertion needle. The biocompatible substrate can be flexible (e.g., can include polyimide). The implantable device is implanted using an insertion needle that includes an engagement feature corresponding to the engagement feature of the implantable device. To implant, an implantable device is reversibly engaged with an insertion needle, the device-loaded insertion needle is inserted into a biological tissue (e.g., to a desired depth), and the insertion needle is retracted, thereby disengaging the implantable device from the insertion needle and allowing the implantable device to remain implanted in the biological tissue.

Abstract: A system and method for implanting devices into biological tissue (e.g., brain tissue). The system may include a biocompatible probe, an integrated circuit (IC) chip tethered to the probe, a cartridge comprising a temporary attachment surface by which the probe is removably coupled to the cartridge, a needle to reversibly engage with the probe, a robotic arm to hold the needle, and a microprocessor controller. The microprocessor controller may control the robotic arm and the needle to remove the probe from the temporary attachment surface using the needle, pierce the biological tissue with the needle and the probe, withdraw the needle while leaving the probe within the biological tissue, and detach the IC chip from the cartridge, leaving the IC chip with the biological tissue.

Abstract: Methods are provided for the fabrication of microneedles. Microneedles fabricated according to the herein described methods will generally be constructed of multiple lengths of wire winded together, brazed and further manipulated to include a reversible engagement feature. The subject microneedles may find use in a variety of applications and, among other purposes, the reversible engagement feature of such a microneedle may by employed in implanting an implantable device into a biological tissue. Also provided are methods of inserting an implantable device into a biological tissue having an outer membrane. The subject methods may include ablating a section of the outer membrane and inserting the implantable device through the ablated section of outer membrane, including e.g., where the implantable device is inserted using a microneedle including e.g., those microneedles for which methods of fabrication are provided herein.
