Medical device giant Boston Scientific (NYSE:BSX) announced the launch of its next-generation Guidezilla Guide extension catheter, despite the best efforts of rival Vascular Solutions (NSDQ:VASC), who attempted to win a legal order blocking the Guidezilla device.

The Guidezilla catheter features a stainless steel "hypotube" shaft that resists kinking and helps physicians introduce interventional devices to the surgical site. The tube also has a hydrophilic coating that reduces friction, making it easier to navigate through the vasculature access hard-to-reach areas.

The device is at the center of an ongoing legal snafu with Vascular Solutions, which asked a federal judge to block Boston Scientific from releasing the product. Vascular Solutions CEO Howard Root called Guidezilla "one of the most blatant plagiarisms of a patented medical device that I have ever encountered."

Boston Scientific filed a sealed motion opposing the injunction bid, according to court documents.

BSX shares rose 1.6% to close at $9.61 at the end of the day.
