## Abstract

The invention is directed to an endoscopic assembly having an endoscope, particularly a flexible hysteroscope and an outer sheath disposed about a length of the shaft of the hysteroscope which has an expandable member such as an inflatable balloon for sealing the assembly within a body lumen or cavity. Specifically, the endoscope assembly is configured for delivery of an occlusive contraceptive member to the patient's fallopian tube. The invention is also directed to an endoscope having a driving member for movement of a medical device within the working lumen of an endoscope. In one embodiment the driving member is a friction wheel which engages an elongated medical device disposed within the working channel of the endoscope to effect longitudinal movement of the medical device.

## Claims

### Claim 1

An endoscope for delivering a contraceptive device to a fallopian tube comprising:
a. an elongate shaft;
b. a working channel extending through at least a portion of the elongated shaft;
c. a loading port in a proximal portion of the elongated shaft for loading an elongated delivery catheter within the working channel, said delivery catheter comprising a catheter lumen, an outer sheath disposed over said lumen and an occluding contraceptive device disposed in said lumen;
d. a device driver for contacting and longitudinally moving the elongated delivery catheter loaded within the working channel;
e. a stabilizing wire, said stabilizing wire for contacting and positioning said occluding contraceptive device within said lumen while said outer sheath is disposed over said lumen and occluding contraceptive device;
f. an actuator disposed about the proximal portion of the endoscope said actuator including first and second levers operably attached to each other at a rotation point, said first lever structured to receive the outer sheath of the delivery catheter thereon and to move said outer sheath backward within the working channel, and said second lever structured to receive said stabilizing wire and to move said stabilizing wire backward and forward within the working channel, wherein upon actuation said outer sheath and stabilizing wire are moveable relative to each other to withdraw the outer sheath from over the occluding contraceptive device and to deposit the occluding contraceptive device in the fallopian tube.

### Claim 2 (depends on 1)

The endoscope of claim 1 wherein the device driver is manually operated.

### Claim 3 (depends on 2)

The endoscope of claim 2 wherein the device driver is a friction wheel which extends into the working channel.

### Claim 4 (depends on 1)

The endoscope of claim 1 wherein the loading port in communication with the working channel has a valve to seal about the elongated delivery catheter extending therethrough.

### Claim 5 (depends on 1)

The endoscope of claim 1 wherein the endoscope is a flexible hysteroscope.

### Claim 6 (depends on 3)

The endoscope of claim 3 wherein the friction wheel is finger operable.

### Claim 7 (depends on 1)

The endoscope of claim 1 wherein said stabilizing wire further includes proximal and distal ends and a plunger proximal and distal ends and a plunger operably connected said distal end.
