Area of Science:

  • Vascular Surgery
  • Interventional Cardiology
  • Biomaterials

Background:

  • Femoral arterial puncture is a common procedure, but achieving hemostasis can be challenging, especially in patients on anticoagulation.
  • Existing closure devices have varying efficacy and may leave foreign material in the artery.
  • The Duett sealing device presents a novel liquid procoagulant-based approach for hemostasis.

Purpose of the Study:

  • To evaluate the safety and efficacy of the Duett sealing device for achieving hemostasis after femoral arterial puncture.
  • To compare the Duett device to standard manual compression.
  • To assess the impact of anticoagulation and antiplatelet therapy on hemostasis time with the Duett device.

Main Methods:

  • The Duett sealing device utilizes a liquid procoagulant (thrombin and collagen) to achieve hemostasis.

  • The device is compatible with 5 to 9 Fr sheath sizes and incorporates the vascular sheath.
  • Comparative studies, including the SEAL trial, assessed device safety and ambulation times.

    • Main Results:

    • The Duett device demonstrated safety and efficacy in achieving hemostasis.
    • Significantly decreased times to ambulation were observed compared to manual compression.
    • Patients on anticoagulation or antiplatelet therapy experienced significantly reduced time to hemostasis.

    Conclusions:

    • The Duett sealing device is a safe, effective, and viable alternative for hemostasis after femoral arterial puncture.
    • Its unique liquid procoagulant mechanism provides instant hemostasis without foreign material implantation.
    • The device offers advantages in reducing complications and improving patient recovery, particularly in high-risk populations.
