Remote tissue retraction device
First Claim
1. A medical device, comprising:
- a flexible elongated body, a flexible distal end of the flexible elongated body being configured to be advanced into a body of a patient; and
a vacuum pod disposed at the flexible distal end of the flexible elongated body, the vacuum pod being movable relative to the flexible distal end of the flexible elongated body when the flexible distal end of the flexible elongated body is within the body of the patient, the vacuum pod having no more than one vacuum port configured to suction tissue of the patient thereto when the flexible distal end of the flexible elongated body is within the body of the patient;
wherein the vacuum pod is configured to move between a first position and a second position when the tissue is suctioned to the no more than one vacuum port so as to move the tissue relative to the flexible distal end of the flexible elongated body with the tissue only being attached to the device via suction, the vacuum pod in the first position directly contacting the flexible distal end of the flexible elongated body, and the vacuum pod in the second position being positioned distal to the flexible elongated body and not directly contacting the flexible distal end of the flexible elongated body, wherein the flexible elongated body has a plurality of vacuum ports formed through a sidewall thereof.

Abstract
A medical device for managing tissue in an organ, such as the stomach, for retracting or positioning tissue and related organs to allow certain regions of the stomach to be acquired for a gastroplasty procedure. The medical device includes an elongated body having a proximal end and a distal end, and a tissue treatment device attached to the distal end of the elongated body. The tissue treatment device includes a first jaw opposite a second jaw, and each jaw is adapted to acquire tissue. A retractor is disposed along the tissue treatment device and adapted to be moveable from a delivery position to a retraction position to move or manage the tissue of the stomach. The medical device also includes a collapsible barrier disposed between the first and second jaws of the tissue treatment device to direct tissue into the first and second jaws separately.

9. A medical device, comprising:
-
a flexible tubular body having a proximal end and a distal end, the distal end of the tubular body being configured to be advanced into a body of a patient; no more than one vacuum port being disposed at the distal end of the tubular body and at least one vacuum port being formed through a sidewall of the tubular body, the no more than one vacuum port and the at least one vacuum port each being configured to suction tissue of the patient thereto when the distal end of the tubular body is within the body of the patient; and a coupling element that couples the no more than one vacuum port to the tubular body, the coupling element being movable relative to the distal end of the tubular body from a first position to a second position and from the second position to the first position, the movement of the coupling element between the first and second positions moving the no more than one vacuum port relative to the distal end of the tubular body and to the at least one vacuum port, a first distance extending between the no more than one vacuum port and the distal end of the tubular body when the coupling element is in the first position, and a second distance that is greater than the first distance extending between the no more than one vacuum port and the distal end of the tubular body when the coupling element is in the second position. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17)
