Abstract
Exemplary embodiments of the present disclosure provide method and apparatus for facilitating stretching of a biological tissue by forming a plurality of micro-slits in the tissue. Each micro-slit can be less than about 2 mm or less than about 1.5 mm long, or even less than about 1 mm, such that small gaps that can heal quickly can be formed when the tissue is stretched. The micro-slits can be formed using a plurality of cutting arrangements or an ablative laser. The micro-slits can be formed in various patterns, including staggered rows, circular or spiral patterns, or random patterns.
