We help you so you can help others.

It can be a long road from the invention of a vascular device to regulatory approval.

Whether it’s determining the type of trials needed to evaluate your product, to accurately analyzing its efficacy, to knowing the best way to present it to regulatory agencies, the process can be overwhelming. That’s why VasCore is committed to helping clients worldwide navigate the process, every step of the way. For more than a decade, VasCore has been considered the leader in the strategic development of imaging protocols and the interpretation of ultrasound and radiographic images as part of novel vascular device trials. Every day, we help turn the challenges of approval into successes for effective vascular products.

Expertise

An industry leader. And your leader through the approval process.

Few core labs offer the high level of expertise and thorough, friendly customer service as does VasCore. Maybe that’s why we’re considered the leader in everything from the development of multicenter vascular device imaging protocols, to the analysis of ultrasound and radiographic images, to the reporting of data to sponsors and regulatory groups across the globe.

The VasCore Innovation Strategies

First Iliac Artery Stent Approved in the U.S.

Challenge

A sponsor wants to design a clinical trial to result in approval of their iliac artery stent by the US Food and Drug Administration.

Solution

We designed the duplex ultrasound imaging protocol and trained the sites in the performance of this imaging protocol.

Result

First Iliac Artery Stent Approved in the U.S.

First Major Publication of Carotid Stent vs. Carotid Endarterectomy

Challenge

Carotid artery stenting comes on to the US scene, with the first multicenter high risk carotid stent protocol.

Solution

We develop a common duplex ultrasound protocol for this trial.

Result

First Major Publication of Carotid Stent vs Carotid Endarterectomy

Approval of Renal Artery Stent Based on Duplex Ultrasonography

Challenge

Renal artery duplex ultrasonography, one of the most challenging clinical examinations, is an ideal surveillance study for stents in clinical trials.

Solution

We run such a trial where duplex ultrasonography is the primary endpoint modality.

Result

Approval of Renal Artery Stent Based on Duplex Ultrasonography

The Accepted Definition of Stent Fracture Types

Challenge

Fractures of stents has become a significant concern for manufacturers, physicians, and regulatory groups.

Solution

We helped develop the appropriate methods to study and report stent fractures.

Result

The accepted definition of stent fracture types established

The First Positive Study of Drug Eluting Stents in the Superficial Femoral Arteries

Challenge

Drug eluting stents hold great potential for treatment of peripheral artery disease.

Solution

We developed and validated the process of ultrasound surveillance of endovascular stents in the superficial femoral artery.

Result

The First Positive Study of Drug Eluting Stents in the Superficial Femoral Arteries
