    摘要： A method and apparatus for introducing a first elongate medical device and short wire guide that are coupled together into a work site and remotely disconnecting them within the work site such that a secondary device comprising a catheter member can be introduced over the wire guide to the work site, and/or a second wire guide can be introduced to the work site via a passageway of the primary access device. A system of indicia, such as radiopaque or viewable markers, permit the operator to monitor the relative alignment of the devices within the work site to determine when uncoupling has occurred. In one example of the method, a wire guide and primary access device (e.g., a sphincterotome) is coupled to the wire guide and introduced via a duodenoscope into the biliary system. After performing a first medical operation, the devices are uncoupled with the wire guide being left within the biliary system such that a secondary access device, such as a balloon, biopsy device, stent delivery catheter, dilator, etc., can be introduced to perform a second medical operation without a traditional over-the-wire exchange being required. In another example of the method, a prosthesis, such as a valve or stent, is placed within the work site coupled to a wire guide which is remotely disconnected within the work site and a secondary device, such as a dilation balloon or second prosthesis, is introduced into the work site after the first delivery system is removed.

    摘要： 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.
