Medtronic Expands Limited Release of Its Rist Neurovascular Radial Access Portfolio

February 1, 2021—Medtronic announced expansion of its limited site release of the recently acquired radial artery access portfolio from Rist Neurovascular, Inc., which includes the Rist 079 radial access guide catheter and Rist radial access selective catheter. The acquisition of the privately held Rist Neurovascular closed in August 2020. Terms of the acquisition were not disclosed.

R. Webster Crowley, MD, performed the first-in-patient procedure in September 2020 with the Rist 079 device. Dr. Crowley is Chief of Cerebrovascular and Endovascular Neurosurgery at Rush University Medical Center in Chicago, Illinois.

“Rist 079 radial access guide catheter is the first catheter that has been specifically designed for neurointerventions using the radial artery pathway in the wrist,” commented Dr. Crowley in Medtronic’s press release. “This is the first-of-its-kind device that optimizes transition zones for the required navigability and support that is unique to the radial trajectory when compared to the femoral approach.” Dr. Crowley continued, “The Rist radial access portfolio gives clinicians who perform neurovascular procedures the full spectrum of access and delivery devices that are optimized for the patient’s condition and anatomy. This should help improve the care we deliver to patients treated for neurovascular conditions.”

According to the company, the addition of the Rist 079 radial access guide catheter and Rist selective catheter to the Medtronic neurovascular portfolio enhances the company’s ability to serve patients that require interventional neurovascular therapy. Rist 079 radial access guide catheter and Rist radial access selective catheter received FDA 501(k) clearance last year.

The Rist 079 radial access guide catheter is indicated for the introduction of interventional devices into the peripheral, coronary, and neuro vasculature. The Rist radial access selective catheter is indicated for the introduction of interventional devices into the peripheral, coronary and neuro vasculature and can be used to facilitate introduction of diagnostic agents in the neuro vasculature. It is not intended to facilitate introduction of diagnostic agents in coronary or peripheral arteries, advised Medtronic.
