1. A flexible endoscopic instrument for multiple ligation, said instrument comprising:

  • (a) a flexible endoscope having a forward insertion portion, said endoscope including means for illumination and viewing through said endoscope, means for providing a suction force at said insertion portion, and a working channel;

    (b) a hollow support member having a forward distal end and a rearward portion, said rearward portion being connectable to the insertion portion of the endoscope;

    (c) at least two string-like cords of flexible substantially inelastic material, each of said cords having a first portion overlaying a part of the exterior of said support member and a second portion disposed internally of said support member; and

    (d) a plurality of elastic ligating rings removably mounted in stretched condition on said support member and each of said rings being in overlying contacting relation to each of said cords, said rings being spaced from one another along said support member at successively greater different distances from said distal end of said support member;

    wherein a pulling force may be exerted on each of said cords to cause movement of each of said cords relative to said support member to dislodge one or more of said rings in controlled sequence from said support member, each of said cords being arranged in slack condition between each pair of adjacent elastic rings.
