Abstract
A surgical cutting instrument for removing objects, such as a pacemaker lead or catheter, embedded in biological tissue. The cutting instrument includes a rigid proximal end and a flexible distal end, the flexible distal end having circular opening and a cutting blade disposed longitudinally therein. A control handle connected to the rigid proximal end and extending radially therefrom provides a force applied to an inner member which extends the cutting blade beyond the circular opening and simultaneously rotates the cutting blade to cut tissue exposed to the blade.
