Screen Shot 2014-12-02 At 7.44.04 AMCohera Medical, Inc.®, a leading innovator and developer of absorbable surgical adhesives and sealants, today announced that the U.S. Patent and Trademark Office (USPTO) has issued the Company patent number 8,895,052, titled “Biodegradable Compositions Having Pressure Sensitive Adhesive Properties.”

The patent relates to a novel adhesive designed for surgical mesh or matrix fixation in clinical applications such as hernia repair.  Use of the adhesive could replace the often painful and complicated mechanical fixation methods currently used in surgical mesh placement. The adhesives covered by the patent are high-strength, completely synthetic and resorbable.  A key unique feature is that the adhesive is designed to maintain a solid state at room temperature, and then become sticky when exposed to moisture and heat in tissue, allowing it to be manipulated and placed laparoscopically.  The patent covers variations of this adhesive that allows for multiple products with varying strengths and cure properties, thereby enabling the development of products for additional clinical applications and surgical methods.
“The unique chemistry of this synthetic pressure-sensitive adhesive is a breakthrough in the field of medical glues,” said Dottie Clower, Ph.D., Chief Scientific Officer of Cohera Medical.  “This patent represents a significant advance in the state of the art, and is the culmination of a significant research effort by the company.”
“We are excited to add this patent to our growing intellectual property portfolio, which enhances our leadership position in internal surgical adhesives," said Patrick Daly, President and Chief Executive Officer of Cohera Medical. “This patent protects novel technology that could change the landscape in the surgical placement of meshes and matrices to the benefit of patients worldwide.”
