Surgical robotics company Titan Medical (CVE:TMD) is on a fundraising spree, announcing new details of a planned $22.3 million U.S. public offering after raising $11.7 million in a stock offering in Canada.

The company said that it will offer units at $2.10 apiece for individual shares of common stock paired with a single warrant to purchase a share at $2.65. Titan is offering more than 10.6 million such units and has approval to sell up to 15% more.

Should Titan sell all shares and exercise its full over-allotment, the company expects to raise about $25.6 million. The company plans to use the funds "for ongoing development and commercialization of robotic surgery technologies and general working capital requirements," according to a press release.

The new fundraising effort adds to February’s public sale of more than 9.1 million shares in an offering that raised $11.7 million (C$12.8 million).

The Canadian company develops robotic surgical systems for use in minimally invasive surgeries, featuring its Single Port Orifice Robotic Technology with 3D imaging and interactive instruments.

TMD shares were up 0.8%, trading at C$2.47 as of about 2:10 p.m. The stock has gained more than 450% since it opened on February 26 at C$1.36.
