Peristript 

Intraoperative Device to Remove Cancerous Peritoneum During Cytoreductive Surgery

The Eagle Pro is an innovative device that streamlines the removal of the cancerous peritoneum, which lines the abdominal cavity, during surgery. Eagle Pro incorporates the inflation properties of a balloon and a unique stainless steel ball tip to separate the peritoneum and underlying tissue for easy and quick removal by surgeons.

In the United States, the second leading cause of death is cancer, and among the hardest types of cancer to treat are gastrointestinal cancers. When tumors form in the GI tract, typically the first place they spread to is a thin layer of tissue that lines the abdominal cavity called the peritoneum. The peritoneum forms a barrier between the inside of the abdominal cavity and surrounding tissue, typically muscle. To treat cancerous peritoneum, surgeons perform a procedure called peritoneal stripping, in which the peritoneum is removed. Surgeons currently use a Bovie electrocautery knife to enter the plane between the peritoneum and the underlying anatomy, and then use blunt force to pull the peritoneum off. However, these current methods are very tedious and exhausting for surgeons taking up to 2 hours in an already 8-10 hour surgery. The Bovie also uses heat, meaning surgeons cannot remove the peritoneum around sensitive organs without damaging them and are forced to leave some cancer untreated. There is no device currently designed specifically for peritoneal stripping in all regions of the abdomen without risking damage to surrounding organs. To address these problems, we created the Eagle Pro, an intraoperative device that streamlines the removal of the peritoneum for patients with cancer. The Eagle Pro saves time and effort for the surgeon and ensures all cancer can safely be removed throughout the abdomen. Our device uses the inflation properties of a balloon and a unique metal ball tip to both efficiently enter the plane between the peritoneum and underlying anatomy, and to safely separate these two layers. Eagle Pro is 10 times faster than the current stripping methods, resulting in over $7,000 saved in every surgery. The Eagle Pro makes peritoneal stripping safe and effective for any patient suffering from peritoneal cancer.
