Embodiment Construction

[0028] The present invention relates to a device, system and method for identifying regions of ablated tissue. The present invention also relates to a device, system and method for assessing contact between a therapeutic element and tissue and / or for assessing an obstruction of a body cavity by said therapeutic element. Specifically, the devices, systems and methods may include one or more optical fiber sensors and a processing unit for receiving emitted light and / or reflected light from tissue and based on the relationship between ablated tissue and non-ablated tissue One or more decisions are made based on spectral differences.

[0029] now refer to figure 1 , shows an exemplary cryotherapy system including a device with a fiber optic sensor for hyperspectral data acquisition. Hyperspectral data acquisition can include scanning tissue surfaces and collecting images along the electromagnetic spectrum. This can form a data set known as a hypercube, which includes layered im...

Abstract

A device, system, and method for identifying an area of ablated tissue. Specifically, the device, system, and method may include a device having one or more fiber sensors and a processing unit for receiving emitted and / or reflected light from tissue and making one or more determinations based on the received light regarding ablated tissue, tissue contact, and / or occlusion. Each of the fiber sensors may include at least one multimode waveguide segment and at least one singlemode waveguide segment, or each of the fiber sensors may be singlemode waveguide. Further, each fiber sensor may have a core with long-period grating for optically coupling light from tissue to the fiber sensor. The processing unit may include a beam processing apparatus and a hyperspectral imaging and analysis apparatus, and may optionally include a light source.

Description

technical field [0001] The present invention relates to a device, system and method for identifying regions of ablated tissue. The present invention also relates to a device, system and method for assessing contact between a therapeutic element and tissue and / or for assessing an obstruction of a body cavity by said therapeutic element. In particular, the devices, systems and methods may include one or more fiber optic sensors and a processing unit for receiving emitted light and / or reflected light from tissue and making decisions about ablation based on the received light. One or more determinations of tissue, tissue contact and / or obstruction. Background technique [0002] Arrhythmia is a condition in which the normal rhythm of the heart is interrupted. Certain types of cardiac arrhythmias, including ventricular tachycardia and atrial fibrillation, can be treated with ablation (eg, radiofrequency (RF) ablation, cryoablation, ultrasound ablation, laser ablation, microwave ...
