Dakota Vascular’s Dr. Patrick Kelly, Inventor of Groundbreaking Liquet Versus™

Catheter, Celebrates FDA Clearance for Innovative Blood Clot Treatment

SIOUX FALLS, S.D. – December 19, 2024 – Dr. Patrick Kelly, a prominent vascular surgeon

and the inventor of the Liquet Versus™ Catheter, is proud to announce that the U.S. Food and

Drug Administration (FDA) has granted 510(k) clearance to the revolutionary device. Dr. Kelly,

who now practices at Dakota Vascular in Sioux Falls, South Dakota, developed the Liquet

Versus™ Catheter to transform the treatment of pulmonary artery blood clots, addressing a

critical need for improved patient outcomes.

The Versus™ Catheter introduces a pioneering approach to clot treatment known as

Hemodynamics-Led Thrombolysis (HLT). By providing real-time pulmonary artery pressure

monitoring, the catheter empowers physicians to personalize therapy based on individual patient

responses—marking a significant advancement in vascular care.

“As a physician, I saw an opportunity to create a solution that puts actionable, real-time data into

the hands of clinicians, allowing them to optimize clot treatment and improve outcomes for

patients,” said Dr. Patrick Kelly, vascular surgeon and innovator. “The Liquet Versus™ Catheter

is a culmination of years of work, and I am thrilled to see it gain FDA clearance and enter the

market where it can make a life-changing impact.”

Key Features of the Versus™ Catheter:

• Real-Time Pulmonary Artery Pressure Monitoring: Provides live data during

treatment, enabling clinicians to adjust therapy to each patient’s unique needs.

• Dual-Tip Telescoping Catheter: Enables simultaneous delivery of thrombolytics to both

lungs with a single device, offering access site alternatives to the physician, and

improving healthcare efficiency.

• Flexible Placement Options: Offers standard guidewire techniques or flow-directed

balloon placement for versatile use by clinicians.

The Liquet Versus™ Catheter represents a critical leap forward for patients suffering from blood

clots that block arteries in the lungs. By enabling personalized therapy through direct

hemodynamic monitoring, the device addresses both safety and efficacy in clot treatment.

Dr. Patrick Kelly’s work highlights his commitment to innovation and advancing vascular care.
