A clip device delivery apparatus for hemostasis has an introducer tube, such as an endoscope or sheath having a distal end portion and working channel receiving an operating wire detachably securing a clip device comprising tissue engaging arms and a sliding ring for closing the arms. A protective cap having a tube mounting section and a distal section having a receiving chamber define a passageway therebetween, the mounting section being mounted to the introducer tube distal end portion and the distal section receiving tissue and clip arms to close about tissue. The operating wire and clip device are inserted within the working channel. Methods of grasping tissue are provided using the introducer tube introduced endoscopically into a patient, tissue suctioned and clip arms deployed into tissue receiving chamber, sliding ring moved distally to close the clip arms about the tissue, and the clip detached from the operating wire. |
