CryoLife, a distributor of implantable living human tissues for use in cardiac and vascular surgeries, has purchased Hemosphere.

CryoLife president and chief executive officer Steven Anderson said, "We believe that this acquisition is well in-line with our cardiovascular focus and look forward to integrating the business and collaborating with the Hemosphere team to train our sales reps on the HeRO Graft."

HeRO Graft is a vascular access device which is used as an alternative for patients using catheters for end-stage renal disease Hemodialysis and is implanted completely under the skin, which reduces infection risk.

The HeRO Graft is clinically proven to maintain long-term access for hemodialysis patients with venous outflow obstruction.

CryoLife distributes CryoValve SG pulmonary heart valve, CryoPatch SG pulmonary cardiac patch, BioGlue Surgical Adhesive, PerClot and BioFoam Surgical Matrix.
