Abstract
The invention relates to a tissue monitoring apparatus, a tissue monitoring method and an ablation lesion monitoring, measuring, and controlling automated algorithm incorporating diffuse reflectance spectroscopy (DRS) and/or Arrhenius model thermal denaturation kinetics for determining the characteristics of the lesion or the tissue, especially for identifying the transmurality of the ablation lesion. The invention pertains to a device for and method of real time monitoring of lesion formation as ablation is being carried out.
Claims21
A system for monitoring tissue comprising:
- a catheter, the catheter having an elongated body member having a proximal end and a distal end;
- a biasing element in the distal end, the biasing element configured to bias the distal end into contact with a first tissue portion,
- wherein the distal end includes:
- an optical emitting element, the optical emitting element oriented to emit optical radiation into the first tissue portion,
- an optical receiving element oriented to collect optical radiation, the optical radiation indicating characteristics of the first tissue portion;
- wherein the optical receiving element and the optical emitting element are arranged to be spatially offset along a first longitudinal axis of the distal end, and along the face of the first tissue portion, and
- a workstation, the workstation comprising
- an optical radiation analysis module stored in a memory and executed by a processor, configured to process the optical radiation collected by the optical receiving element using spatially offset diffuse reflectance spectroscopy, wherein the processing element is configured to calculate the rate of denaturation of the tissue adjacent to the distal portion.
