Embodiments of the present invention relate to hand sewing needles that have periodic markings to facilitate the creation of stitches of equal length and spacing. Because regular stitching can be difficult to produce by hand but is nevertheless necessary for a garment or other sewing product to be considered of quality, presentable, and professionally made, embodiments of the invention aid those with little sewing experience in producing regular stitching. Embodiments of the present invention also relate to methods for producing and using the disclosed hand sewing needle.

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.
