Were any of you part of this study? I was wondering if anyone knew if they had a HycroCoil ( a platinum coil coated with a microporous expandable hydrogel which expands only when the hydro gel meets blood, filling the aneurysm space) made by MicroVention, Inc.. I know I had plain GDC coils. I was never asked if I wished to be part of this study (came through the emergency room so I don't remember much!:)) but this new HycroCoil sounds really interesting.


Final Patient Enrolled In Internatioal Trial of MicroVention's HydroCoil(R) Embolic System

ALISO VIEJO, Calif., April 5 /PRNewswire/ -- MicroVention, Inc., a leading developer, manufacturer and marketer of minimally invasive treatments for cerebral and peripheral vascular diseases, announced today that the 500th and final patient has been enrolled in the independent, physician-designed and -managed, international trial of its HydroCoil(R) Embolization System (HES) for treating cerebral aneurysms. Cerebral aneurysms are potentially deadly bulges or sacs in the wall of an artery in the brain.

The head-to-head prospective, blinded, randomized trial, titled HydroCoil Endovascular Aneurysm Occlusion and Packing Study (HELPS), compares the results derived from the HydroCoil system to results from approved bare platinum coils, currently considered the mainstay of endovascular aneurysm therapy. The trial is based in the United Kingdom where it is managed by the Lothian Health Board with initial support from the UK's National Health Service, but a total of 24 medical centers from Scotland, England, Wales, Germany, France, Australia, Brazil, Northern Ireland, Argentina and the U.S. are participating.

Philip White, M.D., of Western General Hospital in Edinburgh, Scotland, the study's chief investigator, will present unblinded safety data and initial angiographic procedural data at the World Federation of Interventional and Therapeutic Neuroradiology meeting (WFITN) in Beijing in September.

"The high level of interest in this trial among the physician community and enthusiasm for obtaining proper scientific evidence allowed us to enroll 500 patients relatively quickly," Dr. White said. "I'm certain that the interest was increased by the fact that the trial was designed and run by physicians who understand the importance of the work we are doing, and the potential of the innovative HydroCoil system that MicroVention has developed to treat cerebral aneurysms. These physicians regularly treat patients who have suffered cerebral aneurysms and realize the potential severity of cerebral aneurysms and the challenges they present. I am very grateful to all our collaborators for their enthusiasm and support and most of all to the 500 patients who have consented to participate in HELPS for the benefit of future aneurysm sufferers. I look forward to sharing the progress we have made in Beijing in September."

Mike Kleine, President and CEO of MicroVention, said the HycroCoil technology, which is a microporous expandable hydrogel, will prove to be a more durable solution for endovascular occlusion of aneurysms. HydroCoil combines the features of greater space filling, cellular organization and mechanical stability with the delivery and handling characteristics of a detachable platinum coil.

"Our goal for this trial is to demonstrate the value of our HydroCoil system to the physician who will be using it in a clinical setting," Kleine said. "Ultimately we believe our HydroCoil system will become the gold standard for treating cerebral aneurysms. We applaud the independent scientific approach that was undertaken by the physicians in HELPS. Unlike other endovascular coil studies, the HELPS trial allowed platinum coils from all manufacturers to be used, and had a primary endpoint of aneurysm recurrence at 18 months versus 6 months in other studies. We feel these HELPS Trial endpoints reduce bias, compare a standard of care more reflective of current practice and allow for a longer and more definitive assessment of the technology's durability. This further demonstrates our belief that HydroCoil will prove to be a superior treatment option.

"The HELPS trial enrollment completion represents a significant milestone in the treatment of cerebral vascular disease," Kleine added. "When evaluating this data along with the many other published and presented data on HydroCoil, we trust the outcomes will further demonstrate the consistency already achieved in these studies -- a significant improvement in recurrence and retreatment rates."

About the HES Procedure

The HydroCoil Embolic System is a unique endovascular embolization device combining the Company's platinum microcoil technology with a proprietary, highly-expandable microporous hydrogel called Intelligel. The Intelligel polymer is a responsive or "smart biomaterial" that does not swell until a period of contact with blood. This responsiveness gives physicians the ability to precisely control delivery of the device and allows for repositioning if necessary. When the hydrogel swells, it provides improved filling of the aneurysm. HydroCoil combines the safety and ease of use of platinum coils with the filling and mechanical stability properties of the hydrogel. HydroCoil offers a new therapeutic alternative to the current treatment choices of platinum coil embolization and neurosurgical clipping, and is also being used clinically to treat fistula and peripheral vascular aneurysms.

Nope, darnit - I have the GDC coils.............sounds super interesting tho! Lots of promise! Thanks for sharing this Julie!

Plain old platinum for me. But you know, I recall a guy on the board talking some time ago about coils coated in gel, but not sure if he was simply asking about them or if he had them. Not sure if he's still around.

I have some of them, here's a quote from the NS (that fixed me up) site on the Net.

"Your patient is doing well. We were able to occlude the aneurysm using a balloon remodelling technique (see attached images).

A combination of platinum and HydroCoils were used. At this time I feel he is well protected.


Diane, it might have been me that mentioned this?

Hi Guys

And yes I have quite a few of them along with the platinum. A mixture of both. Didn't know it was part of a study, though. I had the first coiling in 6/05 and then the second in 5/06. When he told me he was using some hydrocoils and explained them to me, I thought it was brillant! I was up for anything to get rid of this giant aneurysm. But unfortunately, they had to do it again. I don't think it had anything to do with the coils failing, it was because of the size of the annie and all the coils shifted and compressed. Thus the 2nd surgery was required. And now it's opened up again to 9mm but I'm having no symptoms. I'm wondering if the hydrocoils can somehow "do there stuff" and hopefully bulk up and fill up that space which opened up????? Would be nice, 'cause if the symptoms come back, they're talking full occlussion of the entire Lt. carotid.I'm not sure I want more hardware in my head. Thanks for the info. Kat

Hi folks,

Not posted for a while so forgive my absence. Also bumped this old topic up as it is clear Hydrogel coils are not that new. Main reason is that Mo has been doing fabulously well. :) Save for a few balance issues (diagnosed as blood pressure irregularities and now treated), eye sight slightly impaired and short term memory issues she has made a full recovery from a ruptured aneurysm this time last year (level 4 SAH).

That is until the 6 month Angio and a diagnosis that re-coiling was required.:(

Does anyone have any more recent advice or information about Hydrogel coated coils? Its just that Mo has been asked to take part in a study and I'd like to know more.:confused:

Oh by the way she is in hospital now, they do it tomorrow and she was only asked this evening!!!

Hi Dave, I'm sorry I cannot be of any help. Just wanted to send along some good vibes for Mo and you as she participates in this study. Hopefully, someone will come along and offer some info.

All the best.
