“In treating peripheral arterial disease below the knee with balloon angioplasty, dissections of the popliteal, tibial and peroneal arteries occur with considerable frequency,” explained Chris Landon, business leader of Image Guided Therapy Devices at Philips. “With the Tack endovascular system from Philips, interventionists can reliably repair below-the-knee arterial dissections – and in doing so, improve major amputation rates and quality of life.”
Philips has previously reported data from the TOBA II and III studies, which evaluated the Tack endovascular system for superficial femoral and proximal popliteal artery dissection repair following uncoated balloon angioplasty and/or drug-coated balloon (DCB) angioplasty. These multicenter, global and European studies demonstrated that the use of the Tack endovascular system resulted in overwhelming dissection resolution following uncoated or DCB angioplasty.
- In TOBA II, which involved uncoated and drug-coated balloons, dissection repair with the Tack System resulted in 89.6% and 86.5% 12-month primary patency (uncoated balloon group) and freedom from CD-TLR
- In TOBA III, which involved drug-coated balloons, dissection repair with the Tack endovascular system resulted in 95.0% and 97.5% 12-month primary patency and freedom from CD-TLR
There were no major adverse events reported through 30 days in either study.
Together, the TOBA II, TOBA III and TOBA II BTK trials support the safety and efficacy of the Tack endovascular system for post-PTA dissection repair in above- and below-the-knee arterial disease. The 36-month TOBA II BTK data reported at NCVH adds to the robust body of clinical evidence supporting the safety and effectiveness of the Tack Endovascular System in both vessel beds.
Philips Tack endovascular system is currently available for sale in the USA and some EU countries. Further information, including safety information, is available here. The system is part of the company’s peripheral vascular portfolio, which includes advanced interventional imaging systems for precision guidance including Vascular Suite on its Image Guided Therapy System – Azurion; intravascular ultrasound (IVUS) catheters to assess the location of the disease and lesion morphology and guide and confirm the treatment; peripheral atherectomy devices to remove blockages; sculpting balloons to prep the vessel; and peripheral therapy devices, such as Philips’ Stellarex drug-coated balloon, to treat lesions.
