Covidien is launching in the U.S. and Europe its new Viance Crossing Catheter and Enteer Re-entry System, for minimally invasive treatment of chronic total occlusions (CTOs). The company touts these device’s lower pressure thresholds, necessary to penetrate and cross lesions. These devices help address difficult cases that might otherwise require a more radical approach.
More about the devices from their product pages:
The Viance™ Crossing Catheter is a precision instrument designed to quickly and safely deliver a guidewire via the true lumen or subintimal pathways. Its atraumatic, low-profile tip helps the device remain within the true lumen, allowing for more treatment options. In cases where the device tracks into the subintimal space, it creates a very small channel, helping to facilitate reliable re-entry.
- Multi-coiled wire shaft results in 1:1 torque for predicable response
- Fast spin torque handle enables the physician to spin the device quickly to transfer torque
- Device utilizes finesse rather than force to cross and does not rely on capital equipment
The Enteer™ Re-entry System consists of a catheter and guidewire, enabling the physician to reliably target the true lumen from the subintimal channel, above or below the knee. The catheter’s unique, flat shape self-orients in the subintimal space, helping to enable re-entry without complete reliance on visualization.
- Angled re-entry probe at the guidewire tip engages the intima to enter true lumen
- Unique balloon shape self-orients within the vessel for true lumen targeting
- 180° opposed and offset exit ports enable selective guidewire re-entry
