Medical devicemaker MicroTransponder wrapped up a $53 million Series E funding round led by US Venture Partners.

The raise also included participation from GPG Ventures, Exceller Hunt Ventures, Osage University Partners, Action Potential Venture Capital and the Vertical Group. The company said it will use the capital to commercialize its Vivistim vagus nerve stimulation system, an implantable device that aims to improve hand and arm mobility in stroke patients.

"Our investors are energized by MicroTransponder's vision to enable treatment for the millions of stroke survivors that have ongoing moderate to severe upper limb impairment. Our goal has always been to establish Vivistim Paired VNS as the gold-standard stroke rehabilitation intervention. Today is the day this therapy can help more stroke survivors get back to the daily activities, hobbies and experiences they love," CEO and director Richard Foust said in a statement.

Oma Fertility emerged from stealth last week with $37.5 million, including $29 million in equity and another $8.5 million in debt financing.

"Oma Fertility is capitalizing on the opportunity to bring leading-edge technological advancements to the fertility space, meeting the demands of rising infertility rates," cofounder and CEO Gurjeet Singh said in a statement.

It plans to use the investment to grow its business, improve on its platform and hire more staffers.

"This new funding validates our company’s mission, which is to help health plans liberate health data," CEO and founder Dr. Minal Patel said in a statement. "Doing so empowers consumers to make better health choices and physicians to make more informed treatment decisions. Payors also use the platform to drive efficiency in their business which further lowers costs for their members. We are proud to partner with MultiPlan given their leadership position in data and analytics serving nearly every payor in the country."
