Biotronik expands peripheral portfolio with a new treatment tool for interventions in complex lesions

Carnelian support catheter

Biotronik has launched the Carnelian support catheter, designed to improve the access for treatment of tortuous and highly calcified lesions. Carnelian support is indicated for the exchange and support of guidewires into peripheral vasculature.

The launch of the Carnelian support marks the start of a partnership between Biotronik and Tokai Medical Products. Whilst the catheter is from Tokai Medical Products, it is commercially available in most European countries through Biotronik.

Up to 40% of patients with symptomatic peripheral artery disease present with a chronic total occlusion (CTO), a press release states. If just a guidewire is used to cross the CTO, the release continues, there is a risk it will buckle once it encounters resistance by atherosclerotic plaque, stopping it from advancing further. Carnelian support is designed to prevent this buckling by enhancing guidewire control and allowing CTO crossing.

Carnelian support comes in five models and has a low tip profile of 1.6 and 1.8 French. Its tungsten braided shaft and platinum marker contribute to high kink resistance and excellent radiopaque visibility. According to the company, the catheter’s multi-segment shaft design provides a smooth transition from the soft distal tip allowing trackability to the stiffer proximal part that ensures additional push.

“I was impressed by the Carnelian support and Japanese crossing technique that enable the treatment of very complex lesions, as I recently had a chance to demonstrate in live cases at CLIC [Critical Limb Ischemia Course] 2019,” explained Marco Manzi, (Policlinico Abano Terme, Italy). “The Carnelian support catheter is the right tool to tackle the most challenging crossings even in below-the-ankle arteries.”
