1. A clip for ligating tissue, comprising:

  • a folded unitary member having an open end, a close end, and an intermediate section;

    said open end including diverging lip members, said lip members being spreadable to receive tissue to be ligated; and

    said intermediate section including an upper member, a lower member, and opposing retention surfaces on said upper and lower members, wherein said intermediate section is twisted with respect to said open and closed ends, wherein said upper member and said lower member are in the same vertical plane which is perpendicular to the opposing retention surfaces, wherein said upper member does not have an opening therein, wherein said upper member and said lower member do not have projections or sharp ridges on said opposing retention surfaces; and

    wherein said upper member and said lower member have a compressive spring force provided by said closed end between said upper and lower members when issue to be ligated is received between said opposing retention surfaces, said spring force being provided without the aid of a locking mechanism to maintain sufficient compression on said tissue to stop blood flow within said tissue.
