Estimating the term…
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.
A method of making a microneedle comprising a reversible engagement feature, the method comprising:
The method according to, wherein the first and second lengths of wire are tungsten or an alloy thereof.
The method according to, wherein the first and second lengths of wire have diameters of 100 μm or less.
The method according to, wherein the method further comprises passing current through the lengths of wire.
