Claims17
Apparatus for the simultaneous formation of multiple microconduits in a flexible material by abrasion,
- said apparatus comprising an abrasion assembly including a rotating abrading device and a control module electro-mechanically connected to the abrasion assembly for controlling the abrasion by stopping and pulling back the abrading device,
- wherein the abrasion assembly further includes a mask with a plurality of holes therein and an abrasive disk for the formation of multiple microconduits via abrasion of the flexible material protruding through each of the holes in the mask,
- wherein the abrasion assembly also includes an impedance sensing unit and a sensor electrically connected to the mask.
