I am currently employed as a Lead Senior Radiographer at a major North East Hospital.
My wife is suffering from severe refractory hypertension, despite excellent compliance with several anti-hypertensive agents. Despite her current exhaustive list of medications her blood pressure is typically 280/140 mmHg, with a resting tachycardia of around 140 bpm. She has a severely dilated left ventricle, with globally impaired left ventricular systolic function, and has nephritic range proteinuria.
We were made aware of the renal sympathetic nerve ablation therapy, but she has been turned down for this procedure at Barts. Due to difficulties establishing the renal ablation service, and the option of Harley Street treatment would not be funded by her PCT.
The hospital I am employed in has a large interventional unit, and despite several of my Consultant colleagues being keen to carry out this procedure, the equipment required cannot be sourced.
There has been a significant deterioration in my wife's condition in the last few months, and as this ablation therapy is the only chance she has of any improvements in her health, I would appreciate any help that can be given in sourcing the equipment necessary to allow interventional colleagues to carry out this procedure.
Thank you in advance for any assistance that can be offered.

This is a new novel technique designed to apply radiofrequency energy via a rotational directional catheter to the sympathetic network of nerves travelling along the renal arteries. These nerves which are both efferent and afferent play a major role in essential hypertension. Early work is very encouraging and the results of a RCT are to be presented at the American heart Association in November 2010.
The kit is a 6F coaxial system which after selecting the renal artery is used to produce 6-8 burns at different circumferential locations along both renal arteries. A dedicated generator is required which the company supplies.
Although CE marked many European countires are having difficulty getting reimbursemnet for this procedure and further evidence of efficacy is keenly awaited.
