Transit Scientific Introduces XO Cath Embolic-Delivery Microcatheter

July 9, 2024—Transit Scientific announced the first commercial use of the XO Cath embolic-delivery microcatheter for interventional radiology and interventional oncology applications. In November 2023, the company announced FDA 510(k) clearance of the XO Cath microcatheter for the precise delivery of a broad range of embolic agents during complex endovascular procedures.

According to Transit Scientific, the XO Cath microcatheter features a metal hypotube with a minimally tapered low profile and catheter strength that provide pushability into distal vasculature and broad embolic compatibility, stated the company.

The company noted that the XO Cath microcatheter is available in the following sizes:

• 2.0-F 0.021-inch inner diameter for use with standard 0.014- and 0.018-inch guidewires.
• 2.6-F 0.027-inch inner diameter for use with standard 0.014-, 0.018-, and 0.021-inch guidewires.

Both sizes are offered with 90-, 110-, 130-, 150-, 175-, and 220-cm working lengths for radial access procedures. Additionally, both microcatheters are offered with either a straight or bern-shaped tip, advised the company.

Transit Scientific stated that Richard Saxon, MD, an interventional radiologist at North County Radiology Associates in San Diego, California, performed the first procedure—a prostatic artery embolization—using the XO Cath 2.0-F, 130-cm microcatheter with a bern-shaped tip; the procedure involved significant vessel tortuosity.

The company reported that Dr. Saxon accessed the treatment site from the right femoral artery and began in the left prostatic artery where he deployed 100- to 300-μm and 300- to 500-μm microspheres and then tracked XO Cath to a wedged position. After treating the left prostatic artery, he navigated to the right side through a 5-F support catheter and finished treatment on the second side.

“The pushability, visibility, and trackability of the XO Cath were notable, enabling precise maneuverability even in challenging anatomical conditions,” commented Dr. Saxon in the Transit Scientific press release. “It tracked incredibly well around tight turns and bends, allowing for distal and precise embolic delivery. In addition, the microcatheter’s luminal size allows for strong injection rates and high-quality imaging.”
