Device for minimally invasive spine surgery
OHSU # 1807
The OHSU surgical device for minimally invasive spine surgery combines a clip and applicator to create a water-tight closure of the dura reducing risk of spinal fluid leaks. Replacing cumbersome traditional sutures, the device promotes an everted edge to edge tissue closure reducing the risk of adhesion to the underlying spinal cord.
Inadvertent tears of the dura (covering of brain and spine) are technically difficult to repair using traditional suture methods during minimally invasive spine surgeries due to tight, narrow corridors accessing the surgical site. In 1999, an estimated 1.2 million spine surgeries were performed annually with a durotomy incidence of 3 to 17%. Dura closure using sutures can consume up to 1 hour of surgeon time. Operative time is very expensive, approximately $50/minute, therefore, a health care savings of approximately 10 minutes per case, or $1,250, would be realized using the OHSU device.
