Endoscopic tissue apposition device with multiple suction ports
First Claim
1. An endoscopic tissue apposition device comprising:
- an elongate capsule body that is configured to be oriented in a longitudinal direction for endoscopic insertion into a patient, the capsule body including an outer surface and having at least two suction ports to capture tissue when a vacuum is applied to the suction ports, each suction port formed by an opening through the outer surface of the capsule body, the at least two suction ports being spaced apart in the longitudinal direction; and
at least one tissue securement device deployable from the capsule body to secure tissue captured with the suction ports.

Abstract
The present invention relates to an improved endoscopic tissue apposition device having multiple suction ports. The invention permits multiple folds of tissue to be captured in the suction ports with a single positioning of the device and attached together by a tissue securement mechanism such as a suture, staple or other form of tissue bonding. The improvement reduces the number of intubations required during an endoscopic procedure to suture tissue or join areas of tissue together. The suction ports may be arranged in a variety of configurations on the apposition device to best suit the desired resulting tissue orientation. The inventive tissue apposition device may also incorporate tissue abrasion means to activate the healing process on surfaces of tissue areas that are to be joined by operation of the device to promote a more secure attachment by permanent tissue bonding.

8. A method of endoscopically joining internal body tissue, the method comprising acts of:
-
(a) providing an endoscopic tissue apposition device including an elongate capsule body that is configured to be oriented in a longitudinal direction for endoscopic insertion into a patient, the capsule body including an outer surface and having at least two suction ports to capture tissue when a vacuum is applied to the suction ports, each suction port formed by an opening through the outer surface of the capsule body, the at least two suction ports being spaced apart in the longitudinal direction, the endoscopic tissue apposition device further including at least one tissue securement device supported by the capsule body to secure tissue captured with the suction ports; (b) navigating the tissue apposition device down an esophagus to an internal treatment site; (c) applying vacuum to the tissue apposition device to capture at least two portions of tissue with the suction ports; and (d) advancing a tissue securement device through the tissue to secure the tissue portions together. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. An endoscopic tissue apposition device comprising:
-
an elongate capsule body that is configured for endoscopic insertion into a patient, the capsule body including an outer surface and having two elongate suction regions that are configured to capture tissue when a vacuum is applied thereto, each suction region including an opening formed through the outer surface of the capsule body, each suction region extending along the outer surface in a longitudinal direction, the suction regions being spaced apart in a direction transverse to the longitudinal direction; and at least one tissue securement device supported by the capsule body to secure tissue captured with the suction regions. - View Dependent Claims (16, 17, 18, 19)
