FDA cleared Route 92 Medical's FreeClimb 46 Catheter with Tenzing 4, the company said on September 28. The system pairs an aspiration catheter with a matched delivery catheter for neurovascular access. It extends a line that already runs FreeClimb 54, 70 and 88.

The pitch is distal reach. Route 92 builds around its Monopoint single-operator design, where a Tenzing catheter sized to the aspiration catheter carries it into smaller vessels. Matthew Alexander, medical director at Sutter Medical Center Sacramento, said Tenzing supports consistent navigation in difficult cases.

Route 92 moved its headquarters to West Jordan, Utah this year and took $50 million in growth financing in April. It counts more than 200 issued US and international patents across the portfolio. A smaller catheter inside an already cleared family is among the cheapest 510(k)s a neurovascular company can run, because the predicate is its own product and much of the bench testing carries over.
