Selera Medical is a pioneering healthcare startup dedicated to transforming the landscape of heart failure management. At the core of their innovation lies a groundbreaking, device-based treatment that aims to alleviate the debilitating effects of fluid overload, a recurring challenge faced by millions of heart failure patients worldwide.
The company's cutting-edge technology, known as Minimally Invasive Lymphatic Offloading (MILO), represents a paradigm shift in heart failure care. By harnessing the body's innate fluid management mechanisms, MILO offers a lifeline to patients trapped in the vicious cycle of fluid buildup and recurrent hospitalizations. Through a one-time, minimally invasive procedure, Selera Medical's device facilitates the efficient removal of excess fluid, providing relief from debilitating symptoms and reducing the need for frequent hospital admissions.
Selera Medical's approach addresses the limitations of conventional treatments, which have remained largely unchanged for over six decades and often fail to address the root cause of fluid overload. By leveraging the body's lymphatic system, MILO acts as a transformative solution, opening new pathways for fluid to flow freely and alleviating the strain on the body.
In May 2024, Selera Medical announced its acquisition by a leading medical device company, positioning itself at the forefront of the heart failure treatment landscape. This strategic move enables the company to accelerate the development and commercialization of its innovative MILO technology, paving the way for widespread adoption and improved patient outcomes.

Solea represents a breakthrough in dental laser technology, offering a distinct experience compared to traditional instruments or earlier laser treatments.
Solea is a novel 9.3-micron CO2 laser that nears the peak absorption of hydroxyapatite (enamel), enabling it to vaporize enamel with speed and precision. This unique wavelength, coupled with computer-controlled motors (galvos) that manipulate the beam thousands of times per second, allows dentists to perform procedures ranging from hard tissue to soft tissue with total control and efficiency.
A key feature of Solea is its variable-speed foot pedal, which lets dentists seamlessly transition from hard to soft tissue by adjusting the pressure applied. This intuitive design streamlines the learning curve for dentists accustomed to using a drill. Solea's three ergonomic handpieces – Contra-Angle, Straight, and Ultraguide – further enhance its versatility across various procedures.
Solea not only improves patient experiences but also offers practice benefits such as increased productivity, new patient flow, and efficiency gains. In October 2022, Convergent Dental received FDA clearance for Solea to aid in reducing mineral loss in dental enamel, protecting teeth against acid attack and caries development. This breakthrough application was commercially launched in November 2023 under the name Solea Protect.
