Primary Outcome Measures:
  • Immediate Sealing Evidenced by no Bleeding on Clamp Release. [ Time Frame: Immediate at time of surgery ]
    The immediate sealing evidenced by no bleeding on clamp release was measured at time of surgery

  • Cumulative Incidence of Significant Bleeding, Infection, Neurological Deficit or Inflammatory/Immune Allergic Response [ Time Frame: Treatment through 6 weeks ]
    The Primary Safety Endpoint Will be the Cumulative Incidence of Significant Bleeding, Infection, Neurological Deficit or Inflammatory/Immune Allergic Response Through 6 Weeks.

Enrollment: 217

Primary Completion Date: December 2009 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Control
Gelfoam and Thrombin
Device: Gelfoam and Thrombin
Apply at the suture site.
Other Name: Gelfoam Plus
Experimental: Investigational Device
ArterX Surgical Sealant
Device: ArterX Surgical Sealant
Apply at the suture site.
Other Name: ArterX Vascular Sealant

Detailed Description:
To evaluate, during open vascular surgery, the safety and effectiveness of the ArterX™ Vascular Sealant when applied prophylactically. Application will be at synthetic vascular graft or patch to native vessel anastomosis prior to the restoration of full systemic circulation to achieve suture line sealing.

Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

Subject must meet all of the following criteria to be eligible for treatment in the Study:

  1. The subject must be equal or greater than 18 years old.
  2. The subject must be scheduled for the surgical placement of a synthetic (i.e., PTFE/Dacron) vascular graft or patch for large vessel repair/arterial reconstruction/hemodialysis access/arteriotomy.
  3. The subject has no child bearing potential or has a negative serum or urine pregnancy test within 7 days of the index procedure.
  4. The subject is willing and able to be contacted for the follow up visits at 6 weeks (± 7 days) and 3 months (± 7 days).
  5. The subject or guardian must provide written informed consent using a form that is reviewed and approved by the IRB.

Exclusion Criteria:

Subjects will be excluded from the Study if any of the following criteria are met:

  1. The subject has a known hypersensitivity or contraindication to heparin, bovine or seafood products.
  2. The subject has a history of bleeding diathesis or coagulopathy, or will refuse blood transfusions.
  3. The subject is currently enrolled in this, or another investigational device or drug trial (IDE or IND) that has not completed the required follow-up period. Note: Extended follow-up trials for products that were investigational but are currently commercially available are not considered investigational trials.
