Renegade HI-FLO Microcatheter
Boston Scientific Corporation (Natick, MA) has introduced their newly designed .027-inch I.D. Renegade HI-FLO Microcatheter. The Renegade HI-FLO uses Vortec Plus Braiding technology in its new fiber and platinum braid design, which the company says offers exceptional flexibility, trackability, and kink resistance. The platinum braid material promotes clear fluoroscopic visualization of the catheter position in the distal vasculature. The polished distal tip with an RO marker enhances visibility during advancement and facilitates positioning.
Additionally, the large (.027-inch) PTFE inner lumen of the device is designed to provide a high-flow, efficient delivery of diagnostic and embolic materials and viscous therapeutic agents to the target site. The high dynamic-burst-pressure rating (800 psi) permits increased infusion pressures to further enhance flow. The clear, advanced Venturi Hub, constructed of chemical-resistant material, promotes chemocompatibility and reduces clogging to facilitate smooth, efficient delivery of embolic material.

Trellis Reserve Peripheral Infusion System
Bacchus Vascular (Santa Clara, CA), introduced its new isolated thrombolytic delivery device at the International Congress of Endovascular Interventions in February 2003. The Trellis Reserve Peripheral Infusion System with I.A. (Integral Aspiration) Technology is now commercially available for the treatment of acute limb ischemia. According to the company, the device is a pharmacomechanical percuntaneous infusion system that can isolate and treat a clot with any standard thrombolytic in a single setting. A unique dual-balloon system maintains the concentration of the infused liquid while its mechanical dispersion wire effectively disperses the fluid throughout the treatment area. The Trellis Reserve system allows the physician to aspirate the treatment area which the company says may reduce the risk of downstream emboli.
The Trellis device was conceived and developed by Thomas Fogarty, MD, founder of Bacchus Vascular, using patented accelerated lysis technology for safer, more cost-effective and minimally invasive management of isolated thrombolysis. It has been successfully used in more than 150 clinical cases and is compatible with current catheterization techniques and authorized CPT codes.

LifeStent Biliary Stent System
Edwards Lifesciences, LLC (Irvine, CA), has launched the LifeStent Biliary Stent, the first of what will be a full line of LifeStent products. The company that innovated the first commercial heart valve and the first truly endovascular treatment device, the Fogarty embolectomy catheter, brings over 40 years’ experience to implantable stent design and catheter-based delivery mechanisms. The LifeStent has a unique, patented helical design that provides flexibility in tracking and in the expanded state while maintaining radial strength. Cut from a solid stainless steel tube and electropolished, the smooth surfaces enable easy recrossing for postdilation. The LifeStent’s 6- to 10-mm sizes are available in lengths from 15 to 94 mm, and the LifeStent LP (low profile) 4- to 7-mm version is .018-inch-guidewire compatible and available in lengths of 18 to 56 mm. Please refer to www.edwards.com for current product indications, contraindications, warnings, and precautions.

Amplatz Ultra Stiff Wire Guide
Cook Incorporated (Bloomington, IN) recently announced the US launch of the Amplatz Ultra Stiff Wire Guide (AUS2). The AUS2 exchange-length wire guide is used for interventional cardiovascular and interventional biliary drainage, abscess drainage, uroradiology procedures and catheter exchanges. The AUS2 features an increased inner diameter wire guide coil that allows for the utilization of an ultra stiff mandril while maintaining tip flexibility. According to Cook, the long, flexible
7-cm taper provides excellent transition to an atraumatic distal tip. The AUS2 is available in the US in both straight and 3-mm J-tip configurations.

In November 2002, Abbott Vascular Devices (Abbott Park, lL), Abbott Laboratories’ cardiovascular device franchise, announced the launch of Perclose A-T (Auto-Tie), the latest generation in suture-mediated vessel closure systems. The Perclose systems, first introduced in 1994, enable physicians to quickly stop bleeding after cardiac catheterizations by providing definitive closure at the puncture site in the femoral artery. Abbott explains that by using a pre-tied knot and stitching, Perclose A-T allows the physician to close the artery quickly and easily, leaving nothing inside the vessel.
According to the company, the new system helps to reduce vessel closure procedure time during cardiac catheterizations by eliminating the complex knot-tying ordinarily associated with suture-mediated closure for easier use and rapid deployment. Abbott also says that further benefits of their suture-mediated products over traditional manual compression techniques (such as direct pressure, sandbags, and mechanical clamps) include increased patient comfort, improved patient recovery, and reduced costs through shorter hospital stays and less nursing time for postprocedure monitoring.

Inner-Lock Introducer Sheath
Rex Medical, LP (Conshohocken, PA), announced in February 2003 that it has received 510(k) clearance to market its Inner-Lock Locking Introducer Sheath. The Inner-Lock sheath is a 6 and 7F (4-cm length) introducer sheath that has a retention mechanism and is designed to facilitate percutaneous entry of diagnostic and therapeutic interventional catheters into synthetic, hemodialysis access grafts. According to the company, the retention mechanism, when activated, will assist in preventing accidental dislodgement or withdrawal of the introducer sheath from the hemodialysis graft both during and following a procedure. Inner-Lock technology also offers a high-flow, 45-degree side-port and radiopaque shaft for fluoroscopic visualization. The company says that the Inner-Lock technology provides an innovative and efficient alternative to the existing dialysis sheath products. Inner-Lock sheaths will be available for commercial sale in the US during mid-year 2003.
