Embodiment Construction
[0035] Referring now to the drawings wherein like reference characters designate corresponding parts throughout the several views, the overall device is shown in FIG. 1. A handle means 20 is connected to a fitting 22 which is in turn connected to an attaching means 24 fixed to an outer sheath 26. A catheter tip 28, which is connected to a catheter hereinafter described, extends from the outer end of the sheath, and a medical device 30 such as an endoscope extends through the handle means and is supported within the catheter. The fitting 24 is connected to an irrigation inflow and aspiration outflow tube 32 which has a suitable connector such as a female luer connector at the outer end thereof. The connector is covered by a conventional dust cap 36 when it is not connected to any cooperating equipment.
[0036] Referring to FIGS. 2-5, the handle means includes a body portion 40 and a handle portion 42 which is slidably and rotatably supported on the body portion. The body portion and t...

A handle includes a body portion and a handle portion which is slidably and rotatably mounted on the body portion. Shoulders on the body portion and the handle portion limit relative sliding movement of the body portion and handle portion. A catheter open at both ends has one end fixed to the handle portion for movement therewith, the opposite end of the catheter having a shape memory tip. A fitting is threadedly connected to an enlarged part of the body portion. A sheath is threadedly connected to the fitting and the catheter is slidable and rotatable within the sheath. An annular channel is provided between the sheath and the catheter, this channel being in fluid communication with a bore in the fitting. The outer end of the sheath has holes therethrough in fluid communication with the channel. An irrigation inflow and aspiration outflow tube is also in fluid communication with the bore in the fitting. A first lock is provided adjacent the fitting for controlling the amount of frictional resistance to lengthwise movement of the catheter relative to the sheath and to lock the catheter in position. A medical device such as an endoscope may be received within the catheter for movement relative thereto. A second lock is supported by the handle portion for locking a medical device in position relative to the catheter.
