KHELIX™ ABLATION EP CATHETERS

Khelix™ Ablation catheters are intended for the delivery of radiofrequency energy to create ablation lesions in the myocardium. They can also be used for the electrical recording or stimulation of endocardial structures. They include a thermocouple for measurement of electrode tip temperature, and are available in irrigated and non-irrigated versions.

The catheters have a deflectable shaft controlled by an adjustment knob on the handle that allows the physician to manoeuvre the catheter tip to the desired location within the heart. They are constructed of two main components: a handle/guidewire and a catheter sheath. The guidewire sits within the catheter sheath which incorporates sensing and pacing electrodes. In the irrigated version, the sheath also incorporates the irrigation tubing. Together, the guidewire and sheath form the catheter shaft. The guidewire is connected to the handle that includes a mechanism for controlling the deflection of the guidewire, and thus the deflection of the shaft.

The handle/guidewire is reposable. After use the sheath (including irrigation tubing) is removed and discarded and the handle/guidewire is sterilised by the hospital’s central sterilisation department using the specially designed sterilisation tray. The sterilised handle/guidewire is then assembled with a new, sterile sheath (and irrigation tubing) ready for use. This process can be performed up to twenty times.
