Problems solved by technology

Disadvantages of using ultrasound include limited field of view, low signal-to-noise ratio (SNR), and subjective technique that can easily lead to variation in scanning ability and image interpretation by sonographers
Electromagnetic tracking techniques that provide real-time location information of the catheter suffer from difficulties in obtaining estimates of myocardial motion and function because tracking is limited to a very sparse set of discrete measurement locations (typically no more than 5 sensor locations)

Embodiment Construction

[0015] According to the present principles, continuous spatial and temporal measurement of boundaries allows real-time mechanical function assessment of the heart and verification of the success of cardiac interventional procedures such as cardiac resynchronization therapy (CRT). In one embodiment, optical shape sensing enabled flexible devices (eg, catheters, guidewires, leads, etc.) are included to perform continuous real-time motion and function assessment of the heart or other organs. In accordance with present principles, embodiments can provide information such as, by direct interrogation of motion providing mechanical asynchrony or other phenomena, by indirect estimates of myocardial viability and cardiac output derived from motion characteristics measured during an interventional procedure. In addition to discrete optical sensors, the present principles provide spatially and temporally continuous sensing of distribution parameters along known three-dimensional (3D) path...

Abstract

A system and method for functioning organ assessment include a sensing enabled flexible device (102) having an optical fiber configured to sense induced strain continuously over a length of the flexible device. The flexible device includes a manipulation mechanism (105) configured to permit engagement with an interior wall of an organ over the length. An interpretation module (115) is configured to receive optical signals from the optical fiber between two phases of movement of the organ while the organ is functioning and to interpret the optical signals to quantify parameters associated with the functioning of the organ.

Description

technical field [0001] The present disclosure relates to shape sensing devices, and more particularly, to systems and methods for interventional procedures with minimally invasive real-time functional organ assessment. Background technique [0002] Interventional procedures performed in a cardiac catheterization laboratory (CathLab) typically involve inserting a catheter through a blood vessel in the arm, leg, or neck and advancing the catheter into the heart. This method allows access to the heart while it is working. The ability to perform these procedures without stopping the heart or requiring the highly invasive sternotomy (cutting the breastbone open), thoracotomy (opening the chest to access the pleural cavity), and thus, these procedures make the Potential trauma is minimized. Many interventional procedures such as percutaneous transluminal coronary angioplasty (PTCA), radiofrequency (RF) ablation, drug delivery, cardiac resynchronization therapy (CRT), and myocard...
