ECUBLENS, SWITZERLAND--(Marketwire - Oct 22, 2012) - Symetis Inc., a private Swiss company developing new transcatheter aortic valve implantation (TAVI) systems, announced during the PCR London Valves meeting that it finished enrollment (n=20) in its First-In-Man (FIM) trial of the transfemoral aortic valve replacement device, the ACURATE TF™ Aortic Bioprosthesis and Delivery System.
ACURATE TF™ FIM Study:
The FIM trial was conducted at four different centers in Brazil and Germany. The device was implanted with a procedure success rate of 95.0% (n=19) as one patient received a valve-in-valve procedure due to too low placement of the bioprosthesis in the LVOT. At 30 days follow-up, the mean gradient is 7.1 ± 3.1 mmHg with a mean EOA of 1.8 ± 0.4 cm2. Paravalvular leak rate is very low with 94.5% of patients exhibiting none to mild leak (<+2). There is no occurrence of mortality at 30 days and one stroke was reported in the valve-in-valve patient. The Study PI, Prof. Helge Moellmann of the Kerckhoff Clinic in Bad Nauheim, Germany, stated: "This 2nd generation TF system has exhibited impressive results in its FIM trial already mirroring the ease of use of its commercially available transapical system, the ACURATE TA™."
ACURATE TF™ Transfemoral Aortic Bioprosthesis
Based upon the same self-seating, self-sealing architecture and stepped deployment concept of its already marketed transapical sister product, the ACURATE TA™ Aortic Bioprosthesis, the ACURATE TF™ is composed of a porcine pericardial tissue valve sutured within a self-expanding nitinol stent covered by a pericardial skirt on the interior and exterior of the device. The bioprosthesis is available in three sizes (S, M, & L) to treat aortic annulus diameters from 21mm to 27mm and its Delivery System boasts an 18F outer diameter delivery catheter.
The CE-mark study has been initiated late September 2012 and the ACURATE TF™ system should receive a CE Mark mid 2013.
Data update on ACURATE TF™ FIM will be presented at TCT2012 (Miami) on Wednesday Oct. 24th at 3:30pm during the Next generation Trans-catheter Aortic Valve Therapies Spotlight session.
