LEFT ATRIAL APPENDAGE CLOSURE
First Claim
1. A constricting tool for minimally invasive access and closure of a left atrial appendage comprising:
- a closure member including a generally loop shaped portion configured to constrict around the left atrial appendage when contracted; and
a tool configured to deploy, control, and position the closure member for closing the left atrial appendage, the tool configured to deploy, control, and position the closure member comprising;
a sleeve including a lumen where the sleeve encases the closure member about the circumference of the closure member, anda line of weakness formed in the sleeve through which the closure member is configured to peel out of the sleeve when the closure member is constricted, the closure member being supported by the sleeve such that the generally loop shaped portion is maintained.

Abstract
A medical device is disclosed for tissue, body lumen and/or cavity closure inside a body of a patient. In one particular application, the medical device can be used for minimally invasive access and closure of a left atrial appendage of the heart. The medical device generally includes a tool used for grasping the appendage, a closure member, and at least one tool to deploy, control, and position the closure member for closing the appendage. The device can also include an expander tool for expanding the working area around the left atrial appendage to improve visibility during the procedure. In other embodiments, the medical device may include other tools, for example an imaging tool for viewing the target area and/or other tools that are considered useful in a left atrial appendage closure procedure.
