ABSTRACT:
This invention relates to novel methods, kits, and devices for stopping hemorrhaging of percutaneous wounds. The inventive subject matter involves insertion of a purse-string suture around the wound, insertion of the free two ends of the suture through a tension collar, manual tightening of the tension collar until hemostasis is achieved, and application of a suture lock to the free ends of the suture to secure the tension collar and maintain hemostasis. After a sufficient period of time to allow complete hemostasis, the suture lock and the tension collar are loosened; if hemostasis has been achieved, the suture lock, the tension collar, and the suture material are removed. If bleeding continues from the wound, the tension collar is tightened and the suture lock reapplied. This process may be repeated until complete hemostasis is achieved, without the need for additional suturing or manual compression.
