Penumbra Launches Lantern Microcatheter


March 31, 2016—Penumbra, Inc. announced the launch of its Lantern microcatheter at the SIR 2016, Society for Interventional Radiology annual meeting on April 2–7 in Vancouver, British Columbia. Lantern is a low-profile, high-flow microcatheter designed to assist in the delivery of diagnostic agents (eg, contrast media) and therapeutic devices (eg, occlusion coils) to the peripheral vasculature. 

Lantern received 510(k) clearance from the US Food and Drug Administration in December 2015. The device is offered in a variety of lengths and tip shapes relevant to peripheral vascular procedures. Lantern’s distal segment is visible under fluoroscopy to aid in the navigation and visualization of the microcatheter during procedures, noted the company.

Also at SIR, Corey Teigen, MD, will present the final results from the multicenter PRISM study, which is designed to assess the safety and efficacy of Penumbra’s Indigo system for peripheral and visceral arterial thrombi and emboli. The Indigo system is a novel mechanical aspiration system for the removal of emboli and thrombi in the peripheral vasculature. Dr. Teigen, who is with Sanford Health in Fargo, North Dakota, will present the study: Abstract 207 at 3:00 PM on April 4 in Room 224 at SIR 2016.

Penumbra stated that PRISM began in 2014 to evaluate the use of the Indigo system for patients with peripheral occlusions secondary to acute ischemia, incomplete reperfusion, and procedure-related distal emboli, using primarily the smaller-size catheters of the Indigo system. The Indigo system includes four catheter sizes (CAT 3, 5, 6, and 8). The aspiration lumen is paired with Penumbra’s continuous vacuum aspiration pump to evacuate clot effectively and efficiently. The company’s Separator technology ensures unobstructed aspiration for the duration of the procedure.
