The objective of this study is to evaluate the safety and efficacy of EVICEL for use as an adjunct to dura sutures in elective cranial surgery to provide intraoperative watertight closure.

This is a randomized, multi-center controlled study evaluating the effectiveness of EVICEL* as an adjunct to sutured dural closure compared to control to obtain an intraoperative watertight dural closure.

Exclusion Criteria:

• Chemotherapy or radiation therapy within 7 days following surgery.
• Conditions compromising the immune system.
• Known hypersensitivity to the components (human fibrinogen, arginine hydrochloride, glycine, sodium chloride, sodium citrate, calcium chloride, human thrombin, human albumin, mannitol and sodium acetate) of the investigational product.
• Female subjects of childbearing potential with a positive pregnancy test prior to surgery.
• Female subjects who are breastfeeding or intend to become pregnant during the clinical study period.
• Participation in another clinical trial with exposure to another investigational drug or device within 30 days prior to enrollment.
