Abstract: A cryogenic probe design is provided containing, for example, an inner coil injection tube with a continuous flow of circulating liquid and an outer jacket enclosing the inner coil injection tube. A transducer may monitor parameters in the region between the inner coil injection tube and the outer jacket. An outer jacket serves to prevent gas leakage. One or more embodiments of a probe design provide continuous flow for example via a continuous and controlled path from inlet to outlet and an expanded thermally transmissive region. Expanding a thermally transmissive region of the cooling zone may be provided, for example, in one or more embodiments of injection tube designs.

Abstract: There is herein described a catheter for measuring a pressure in a cardiovascular system. The catheter comprises: a guiding tube adapted for insertion into the cardiovascular system. The guiding tube defines a lumen for sliding a guidewire therethrough. The catheter further comprises a tip pressure sensor eccentrically mounted relative to the guiding tube and a signal communication means extending therefrom. The tip pressure sensor is for sensing a pressure in the cardiovascular system and the signal communicating means is for transmitting a signal indicative of the pressure to a processing device in order to obtain a pressure measurement reading.

Abstract: An integrated multiple energy ablation system that allows for a variety of ablation procedures to be performed without the interchanging of catheters. A console is provided that is connected to one or more energy treatment devices such as catheters or probes, via an energy-delivering umbilical system. A processor in the console allows a user to selectively control which type of energy is released into the umbilical system and delivered to the energy treatment devices. Cryogenic fluid, RF energy, microwave or direct current as well as laser energy can be supplied in order to cover a wide range of ablation techniques. The integrated ablation station is designed to be compatible with commercial catheters and allows for sequential or simultaneous ablation and mapping procedures to be performed when a deeper and wider lesion capability and/or a broader temperature ablation spectrum is desired.
