Your dural closures must remain strong under pressure - just like you. Close confidently with Adherus AutoSpray Dural Sealant. An adjunct to standard methods of dural repair, Adherus AutoSpray helps provide watertight closure during cranial procedures. Even more importantly, it's designed to maintain dural closure during the critical phase of dural healing.1

17 crosslinks

Adherus AutoSpray Dural Sealant has been designed with an average of 17 crosslinking end groups to increase strength and minimize swelling

Significant burst strength

Maintains burst pressure strength above physiological intracranial pressure in an in vitro model2

0 infections

Among subjects treated with Adherus AutoSpray Dural Sealant in a pivotal randomized controlled trial, there were no device related infections and no cases of meningitis3

99.1% leak prevention

Demonstrated to be 99.1% effective at preventing CSF leaks through 14 days of postoperative follow-up3

1 second set time

The Adherus hydrogel sets in approximately one second. It remains where it is applied.1

90 days

Built to last. Absorbs over approximately 90 days1

Contraindications:

Adherus AutoSpray and Adherus AutoSpray ET Dural Sealant should not be used in confined anatomical spaces where nerve compression is of concern. The hydrogel may swell by up to 13% of its size in any dimension or 46% by volume after application.

Pivotal trial results:

A prospective, randomized, controlled, multicenter pivotal trial was conducted to evaluate the safety and effectiveness of Adherus AutoSpray Dural Sealant. The primary endpoint of this study was a composite evaluation of the safety and effectiveness of Adherus AutoSpray Dural Sealant (n=124 subjects) when compared to an active control (n=126 subjects). The endpoint results were based on the number of subjects who were free from intra-operative CSF leakage from dural repair after up to two applications of sealant during the Valsalva maneuver, CSF leak/pseudomeningocele during the 120-day follow-up period and unplanned retreatment of the original surgical site within 120 days post-surgery. The overall success rate for the complete case analysis was 91.2% in the Adherus group compared to 90.6% in the control group.  Adherus was found to be non-inferior to the control with the non-inferiority margin of 10% (p = 0.005).  In the early post-surgical period when the sealants are expected to function, the overall success rate at the 14-day follow-up on subjects who completed the visit was 99.1% in the Adherus group compared to 95.0% in the control group. In addition, the overall success rate at the 45-day follow-up on subjects who completed the visit was 96.6% in the Adherus group compared to 91.9% in the control group. There were no unanticipated adverse device effects. Among the subjects treated with Adherus AutoSpray Dural Sealant, there were no device related deep wound infections and no cases of meningitis. The type and rate of adverse events observed in this study are consistent with the complexity of the surgical procedure and the co-morbid condition of the treated subjects.1
