PERCUTANEOUS NEPHROSTOMY PLUG DELIVERY DEVICE
First Claim
1. A medical device, comprising:
- a tubular member having a proximal end and a distal end, the tubular member being configured for insertion into a biological body; and
a handle coupled to the proximal end of the tubular member, the handle comprising;
a pusher element disposed within the tubular member, the pusher element configured to deliver a plug through the distal end of the tubular member;
an actuation element; and
a transmission coupled to the tubular member and the actuation element, the transmission configured to cause a retraction of the tubular member relative to the pusher element in response to a depression of the actuation element;
wherein a first depression of the actuation element toward the tubular member urges a partial exposure of the plug; and
wherein a second depression of the actuation element toward the tubular member urges a further exposure of the plug.

Abstract
A device for delivering a percutaneous nephrostomy plug is provided. The device comprises a tubular member configured for insertion into a biological body. The device further comprises a handle coupled to a proximal end of the tubular member. The handle comprises a pusher element, an actuation element, and a transmission. The pusher element is disposed within the tubular member, and is configured to deliver a plug through a distal end of the tubular member. The transmission is coupled to the tubular member and the actuation element, and the transmission is configured to cause a retraction of the tubular member relative to the pusher element in response to a depression of the actuation element. A first depression of the actuation element toward the tubular member urges a partial exposure of the plug. A second depression of the actuation element urges a further exposure of the plug.

9. A medical device, comprising:
-
a tubular member having a proximal end and a distal end, the tubular member configured for insertion into a biological body; a handle coupled to the proximal end of the tubular member, the handle comprising; a pusher element configured to slide within the tubular member to deliver a plug through the distal end of the tubular member; an actuation element comprising; a button; and a spring coupled to the button; a transmission coupled to the tubular member and the actuation element, the transmission comprising; a first rack coupled to the button; a second rack coupled to tubular member; a first gear engaged with the first rack; a second gear engaged with the second rack, the second gear selectively coupled to the first gear; and a roller clutch coupled to the first gear; wherein a first depression of the button urges a first rotation of the first and second gears in a first direction, causing a retraction of the tubular member relative to the pusher element; wherein upon a release of the button the first gear rotates in a direction opposite the first direction but the second gear remains stationary; and wherein a second depression of the button urges a second rotation of the first and second gears in the first direction, causing a further retraction of the tubular member relative to the pusher element.

10. A method of delivering a plug to a biological body, the method comprising:
-
inserting a distal end of a tubular member into a biological body, the tubular member containing the plug at the distal end and a pusher element; causing a first retraction of the tubular member relative to the pusher element in a proximal direction, urging a partial exposure of the plug within the biological body; and causing a second retraction of the tubular member relative to the pusher element in a proximal direction, urging a further exposure of the plug within the biological body. - View Dependent Claims (11, 12, 13, 14, 15, 16)
