Recruitment Status : Completed
First Posted : June 21, 2012

Brief Summary:
The purpose of this study is to further assess the safety and performance of Seal-V as an adjunct to standard surgical procedure for achieving hemostasis in patients undergoing peripheral vascular reconstruction surgeries using synthetic grafts.

Condition or disease Intervention/treatment Phase
C.Surgical Procedure; Vascular (Peripheral) Device: Seal-V Phase 1

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 23 participants
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Prospective, Single Arm, Open Label, Non-randomized Study to Evaluate The Safety and Performance of The Seal-V System
Study Start Date : July 2012
Primary Completion Date : December 2013
Study Completion Date : March 2014

Arm Intervention/treatment
Experimental: Seal-V
A vascular sealant intended to achieve adjunctive hemostasis by mechanically sealing areas of potential leakage in surgical reconstruction of large blood vessels.
Device: Seal-V
Seal-V is applied adjunctively to cover the suture lines.
Other Name: SEAlantis Vascular WP2(A)

Primary Outcome Measures :
  1. TTH, Time to Hemostasis [ Time Frame: Perioperative; within 10 minutes after clamp release ]
    Duration from the point at which circulation is restored to the graft/artery until bleeding ceases at the treatment site

Secondary Outcome Measures :
  1. Successful cessation of bleeding at a treatment site [ Time Frame: Perioperative; within 10 minutes after clamp release ]
  2. Intraoperative blood loss [ Time Frame: Perioperative ]
    Measured by weighing the surgical swabs used only in the application area and used from the time Seal-V was applied until hemostasis

  3. Incidence of successful deployment of the Seal-V device [ Time Frame: Perioperative ]

Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Male or female of >18 years of age
  • Signed Informed Consent
  • Patients requiring vascular reconstruction surgeries using synthetic (such as PTFE, Dacron) or autologous (such as native veins) grafts, including the following:
  • Peripheral bypass surgeries, such as arterio-arterial bypasses [including: axillo-(bi)femoral, ilio-(bi)femoral, femoro-femoral, ilio-popliteal, femoro-popliteal (including below knee), femoro-tibial vessel bypass]
  • Arteriovenous (AV) dialysis access shunt in the upper or lower extremity
  • Patients able and willing to complete all follow-up visits

Exclusion Criteria:

  • Vascular surgery other than peripheral bypass surgeries and arteriovenous (AV) dialysis access shunt procedures as described above
  • Reoperation at the same treatment site
  • Known sensitivity to device materials, such as indigo carmine dye or alginate
  • Pregnant or lactating women
  • Systemic infection
  • Participation in another clinical trial or treatment with any investigational agent in past 30 days
  • Congenital coagulation disorders (e.g., thrombocytopenia [<100,000 platelet count], thromboasthenia, hemophilia, or von Willebrand disease)
  • Severe congenital or acquired immunodeficiency (e.g., HIV infection or long term treatment with immunosuppressive drugs)
  • Prior radiation therapy to the operating field

Intraoperative Exclusion Criteria:

  • Major intraoperative complications that require resuscitation or deviation from the planned surgical procedure
  • Intraoperative change in planned surgical procedure that results in the patient no longer meeting preoperative inclusion and/or exclusion criteria
  • Local infection at the operating field
