Abstract:
1. A capsularhexis device, comprising: a tubular insertion cartridge; a resistive-heating element comprising an electrically resistive, superelastic wire having first and second ends, the superelastic wire formed to include a loop and so that the first and second ends are adjacent and extend away from the loop to form a lead section, wherein the loop collapses as the loop is retracted completely into the tubular insertion cartridge and wherein the loop returns to the loop's original shape as the loop is pushed out of the tubular insertion cartridge; an insulation portion comprising an electrically insulating material that wraps around each of the first and second ends to electrically separate the first and second ends of the superelastic wire such that current enters the loop through one of the first and second ends, flows continuously through the loop, and exits the loop through the other of the first and second ends; and a handle fixedly engaging at least a portion of the lead section; wherein at least a bottom surface of the loop from the first end, of the lead section, around the loop to the second end, of the lead section, is bare such that the loop forms a continuous loop-shaped burn on a lens capsule during application of current for a capsularhexis.
