Abstract:
1. A ligating band delivery apparatus for delivering a plurality of ligating bands within a patient, comprising: a proximal portion for hand held operation, the proximal portion generally fitting within the palm of the operator's hand; a delivery member for receiving a plurality of ligating bands which are loadable thereonto, the delivery member comprising a distal end and a proximal end, a tissue receiving chamber located about the distal end, and a passageway extending proximally from the tissue receiving chamber; at least one ligating band carrier element configured for sequentially urging the plurality of ligating bands toward the distal end of the delivery member; an actuating assembly that includes a proximal actuating mechanism located about the proximal portion of the delivery apparatus and operatively connected to the at least one ligating band carrier element the proximal actuating mechanism comprising a spool; a main suction passageway comprising the delivery member passageway, the main suction passageway communicating with a suction means attachment port located about the proximal portion of the delivery apparatus; a suction actuating interface that communicates with the main suction passageway to control the presence or absence of suction at the tissue receiving chamber, the suction actuating interface configured such that an operator can simultaneously operate the suction actuating interface and actuating mechanism, while one hand remains free to perform other operations.
