SMT Research and Development, Ltd., a privately held company, announced that it has completed its first two clinical cases using the Shimon Embolic Filter [SHEF] (TM). SMT R&D developed a novel technology for brain protection (Neuroprotection) from stroke complication hazards arising from invasive cardiology procedures and heart surgery. The rate of stroke and silent brain damage is the leading severe limiting factor for delivering the trans-catheter and invasive therapeutic modalities. Neuroprotection from stroke and brain emboli is a largely untapped major field. The SHEF filter reduces significantly the risk of emboli (blood clots and other debris) from traveling to the brain. The procedure was performed at the University Medical Center, Utrecht, The Netherlands by Dr. Pieter Stella, Director of Cardiac Catheterization and Interventional Cardiology.
The SMT filter is a proprietary medical device that acts as a filter, allowing normal blood flow to the brain, but filtering and diverting all emboli (blood clot, atheromatous material and calcified debris) downstream, thus preventing stroke. The product is designed to be used during interventional and surgical procedures, remaining in the patient throughout the procedure, and optionally for 24 hours, The device has a curved "snow shoe" design, with opposite stabilizers to fully fixate the device in the aortic arch. The filter is introduced in minutes through an arterial puncture and removed in the same mode. SMT R&D was established in November 2004 and is located in Herzliya, Israel. The SMT Filter device was used in a 57-year-old female patient, and a 54-year-old male patient. Both underwent repeated PCI (percutaneous coronary intervention) for treatment of instent restenosis (re-narrowing within a coronary stent). The patients had high risks of stroke complication due to paroxysmal rhythm disturbance. Rhythm disturbances increase the risk of clot formation within the left side of the heart, mainly in the left atrial appendage. These clots may dislodge and travel to the brain via the blood stream. "It is an exciting beginning of a new era for Neuroprotection. We are pleased with the overall success and ease of implementation of the SMT filter," said Dr. Dov Shimon MD, Founder and CEO, SMT Research and Development, Ltd. "
