Abstract: The present disclosure provides an improved guidewire assembly including a sensor disposed on a distal portion thereof and a proximal connector disposed on a proximal portion thereof for electrically coupling the guidewire assembly to an external device. The proximal connector comprises at least one proximal contact and at least one reflowed insulative element disposed adjacent the at least one proximal contact.

Abstract: A magnetic field generator assembly is configured to be associated with a table supporting a body. The magnetic field generator comprises magnetic field transmitters that are thin (of minimal height) and transparent, or substantially transparent, to x-ray radiation. The magnetic field transmitters are configured to minimally obstruct components of an imaging system and to minimally interfere with image quality.

Abstract: A method and apparatus that utilizes a force-time integral for real time estimation of steam pop in catheter-based ablation systems. The apparatus measures the force exerted by a contact ablation probe on a target tissue and an energization parameter delivered to the ablation probe. The exerted force and energization parameter can be utilized to provide an estimation of the probability of steam pop. In one embodiment, the force and energization metrics can be used as feedback to establish a desired contact force and energization level combination to prevent steam popping.

Abstract: A system for displaying mechanical activation patterns of a heart comprises a data input, a processor, and an output. The data input is for receiving data from an electrophysiology apparatus. The processor is electrically connected to the data input, and is configured to calculate mechanical activation parameters from the data, generate an anatomical representation of the heart from the data, divide the anatomical representation into segments, and generate a depiction that displays magnitudes of the mechanical activation parameter relative to the segments such that performance of a plurality of segments can be simultaneously evaluated. The output is for transmitting the depiction to a display.
