| abstract |
A device for providing or enhancing hemostasis at a vascular puncture site disposed at the distal end of a tissue tract comprises a shaft having a non-compliant surface at its distal end. The non-compliant surface is oriented at an angle which allows it to lie flat over tissue puncture when the tissue tract is oriented obliquely, e.g., as the result of the Seldinger catheter introduction technique. The device may be used by itself or in combination with suturing of the vascular puncture, where the device enhances hemostasis and prevents blood leakage through the primary suture closure. |
