A storage and delivery device for a highly viscous material comprising a delivery cap for connecting a catheter or needle to a cartridge, an interconnect insert and a compression sleeve disposed within the delivery cap for creating a leak proof seal between the cartridge and the delivery cap, and a slide lock to reliably lock the cartridge to the delivery cap. The slide lock includes two holes of a first and second diameter arranged in a figure-eight shape for positively securing the delivery cap to a cartridge.

A stent for maintaining fluid flow through a body passage in a patient comprises a tubular member having an inlet at one end, an outlet at the other end and a lumen extending from the inlet to the outlet. The preferred stent also includes at least one projection on the outer wall of the tubular member which enters the wall of the body passage when the stent is rotated in the proper direction. A kit also is disclosed which includes the stent and a tool for grasping and turning the stent from outside the patient's body.

A balloon catheter with an unreinforced stem collapses compactly. A method of introducing a balloon catheter into the body passage of a patient consists of loading the balloon end of the catheter into the unattached sheath of an endoscope and passing the elongated tubular leg attached to the balloon through the lumen of a working channel of an unattached bridge of an endoscope; then joining the bridge and the sheath to form a unitary endoscope and introducing the balloon into the body passage of a patient. A kit is disclosed which includes a balloon catheter and a separate adapter which can be used to introduce inflating fluid into the balloon.
