Ligating band delivery apparatus
First Claim
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.

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.

16. A ligating band delivery apparatus adapted 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 proximal end, a distal tip portion having a distal edge, a tissue receiving chamber located about the distal tip portion, and a passageway extending proximally from the tissue receiving chamber; at least one ligating band carrier element for sequentially urging the plurality of ligating bands toward the distal edge of the delivery member, the at least one ligating band carrier element comprising a strand like first portion that includes a plurality of retainers spaced therealong, and a second portion that is generally disposed within the passageway of the delivery member, the retainers adapted to carry and urge the ligating bands distally over the distal tip portion until deployment thereover; an actuating assembly that includes a proximal actuating mechanism located about the proximal portion of the delivery apparatus that is operatively connected to the second portion of the at least one ligating band carrier element, such that operation of the proximal actuating mechanism urges the at least one band carrier element further into the passageway; a main suction passageway comprising the delivery member passageway, the main suction passageway suction 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. - View Dependent Claims (17)
