## Abstract

An endoscopic delivery system including an endoscope including at least one imaging device and a working channel, and a catheter arranged to pass through the working channel, wherein the catheter is formed with an observation window on a side portion thereof, the window being in a line of sight of the at least one imaging device.

## Claims

### Claim 1

An endoscopic delivery system comprising:
an endoscope comprising at least one imaging device and a working channel; and
a catheter arranged to pass through said working channel, wherein said catheter is formed with an observation window on a side portion thereof, said window being in a line of sight of said at least one imaging device.

### Claim 2 (depends on 1)

The system according to claim 1, wherein said at least one imaging device is positioned on a distal face of said endoscope to have a front field of view.

### Claim 3 (depends on 1)

The system according to claim 1, further comprising a grasping tool operative to grasp a medical device disposed in said catheter.

### Claim 4 (depends on 3)

The system according to claim 3, wherein said grasping tool comprises an advancement indicator at a proximal end thereof.

### Claim 5 (depends on 4)

The system according to claim 4, wherein said advancement indicator comprises markings.

### Claim 6 (depends on 4)

The system according to claim 4, wherein said advancement indicator comprises a physical click mechanism.

### Claim 7

An endoscopic method comprising:
employing an endoscope that comprises at least one imaging device and a working channel;
passing a catheter through said working channel, said catheter being formed with an observation window on a side portion thereof, and said window being in a line of sight of said at least one imaging device;
delivering a medical device through said catheter; and
viewing advancement of said medical device with respect to said catheter by using said at least one imaging device to view the advancement through said window.

### Claim 8 (depends on 7)

The method according to claim 7, wherein viewing advancement of said medical device comprises viewing a non-distal portion of said medical device via said window without having to view a distal tip of said medical device.

### Claim 9 (depends on 7)

The method according to claim 7, wherein a grasping tool is used to grasp said medical device, and said grasping tool is used both to deliver and retrieve said medical device.

### Claim 10 (depends on 7)

The method according to claim 7, comprising delivering said medical device through an opening in a barrier, wherein a distal portion of said medical device, after passing through said barrier, is not viewable by said at least one imaging device.

### Claim 11 (depends on 7)

The method according to claim 7, wherein said medical device comprises a pylorus plug.
