Intraoperative Tissue Mapping and Dissection Systems, Devices, Methods, and Kits

Abstract

Intraoperative devices are described that assist the surgeon in identifying the location and characteristics of tissues and structures. Devices are also described that have the added capability of marking the location of the identified tissues and structures. This invention also includes devices that can selectively ablate adjacent tissues while avoiding damage and trauma to the identified tissues and structures by combining ablation with sensing, where sensing of either tissue properties, markings made by another device or surgeon, or a reference probe can be used. Devices are also described that protect tissue in the proximity of reference markings or probes by closed loop inhibition of the ablation process. The devices, systems, methods and kits described are adapted and configured to facilitate locating a target structure or target tissue within a body of a mammal, including nerves, peripheral nerves, blood vessels, and tubes such as the ureter. The devices, systems and methods may discriminate between different tissues by exploiting the electrical, mechanical, and physiological properties of the body.
