System for mapping and intervention of an organ within the human or animal body

Abstract

Apparatus is provided for diagnosing or treating an organ or vessel, wherein a device having at optical fiber contact force sensors disposed in a distal extremity thereof and a deflection mechanism configured to deflect the elongate body at a location proximal of the distal extremity. The optical fiber contact force sensors are configured to be coupled to processing logic programmed which computes a force vector responsive to detected changes in the optical characteristics of the optical fiber contact force sensors arising from deflection of the distal extremity resulting from contact with the tissue of the wall of the organ or vessel.

Description

technical field [0001] The present invention relates to devices for detecting and treating organs that are capable of calculating multi-dimensional force vectors resulting from contact between the distal tip of the device and tissue of the organ wall. Background technique [0002] Over the years, the exploration and treatment of various organs or vessels has become feasible through the use of catheter-based diagnostic and therapeutic systems. Such catheters are introduced from blood vessels leading to the lumen of the organ being explored or treated or alternatively can be introduced directly through an incision made in the organ wall. In this way, the patient avoids the trauma and prolonged recovery time typical of open surgical procedures. [0003] In order to provide effective diagnosis or treatment, it is often necessary to first map the diagnosed area very accurately. Such mapping may be performed, for example, when selective ablation of current pathways in the heart ...

Problems solved by technology

Although the publication discloses that the strain sensor can be placed in a deformable covering, like Bosselman's, it does not describe the calculation of the bending angle because of the material characteristics of the deformable covering.
