ABSTRACT:
A apparatus is disclosed that is adapted for delivery of a multiplicity of pre-loaded ligating bands within patient, such as to treat hemorrhoidal tissue. The apparatus comprises a delivery member that includes a tissue receiving chamber at the distal end that communicates with a passageway that represents part of the main suction pathway that connects with a suction means. The proximal portion of the apparatus includes an actuating mechanism that is operatively connected to one or more band carrier elements, such as strands with bead-like retainers, which receive and urge the ligating bands over the delivery member for deployment. The actuating mechanism and suction actuating interface are configured such that they can be controlled while the operator retains the other hand for another operation, such as to manipulate an anoscope. In one embodiment, the proximal portion includes a pistol-shaped grip portion, while the actuating mechanism comprises a knurled wheel.
