1. A device for occluding fluid flow between two walls of tissue in a patient, said device comprising:
- a first jaw configured to apply compressive force against a first of the two walls; and
a second jaw configured to apply compressive force against a second of the two walls upon installing the device, wherein, when installed, said first and second jaws compress the two walls therebetween;
said first and second jaws having an open configuration, in which first end portions of said first and second jaws are joined by a joint and second end portions of said first and second jaws are separated, said first and second jaws being movable to a closed configuration in which said first end portions are joined by said joint and said second end portions are connected by a locking mechanism.

Abstract
Devices, tools and methods for occluding fluid flow between two walls of tissue in a patient. Two walls of tissue are compressed together with sufficient compressive force to prevent fluid flow between the two walls, while ensuring that the compressive force is not so great as to cause tissue necrosis. The devices, tools and methods may be carried out using minimally invasive surgical techniques, such as in reduced-access surgical sites. Devices, tools and methods are provided for occluding an atrial appendix.

14. A tool for minimally invasive delivery and installation of an occlusion device, said tool comprising:
-
an elongated shaft connecting distal and proximal end portions, said tool being configured and dimensioned to deliver said distal end portion through a small opening in a patient, to a reduced-access surgical location, while said proximal end portion of said tool remains outside of the patient; said distal end portion including a platform configured to releasably engage the occlusion device; and said proximal end portion includes a release actuator actuatable from outside of the patient, to release the device from said distal end portion located in the reduced-access surgical location inside the patient. - View Dependent Claims (15, 16)

17. An assembly comprising:
-
a device releasably mounted to a distal end portion of a tool, said device and tool configured and dimensioned for delivery of the device through a minimally invasive opening in a patient to a target surgical site, while a proximal end portion of the tool remains outside of the patient, for occluding fluid flow between two walls of tissue in a patient; said device comprising a first jaw configured to apply compressive force against a first of two walls of tissue to be compressed together and a second jaw configured to apply compressive force against a second of the two walls upon installing the device, said first and second jaws connected at first end portions thereof by a joint; said tool comprising an elongate shaft connecting distal and proximal end portions, said distal end portion including a mating feature configured to releasably mate with said device. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35)

36. A method of performing an occlusion of fluid flow between two walls of tissue in a patient said method comprising:
-
inserting an occlusion device connected to a tool through a minimally invasive opening in a patient; delivering the occlusion device to a location of the two walls to be occluded; positioning opposite jaws of the device against the two walls, respectively; clamping the walls between the jaws by closing and locking the jaws; and releasing the device from the tool. - View Dependent Claims (37)

38. A method of implanting a clip comprising:
-
providing an implant system comprising an implantable clip having an elongate body and movably mated with an elongate shaft that extends between a proximal and distal end; inserting the implantable clip through a surgical opening while the clip is positioned in a low profile configuration; moving the implantable clip relative to the shaft after insertion to position the clip for clamping; clamping tissue between clamping members of the implantable clip; and detaching the clip and removing the elongate shaft.

39. A method of articulating and detaching a medical device comprising:
-
providing an elongate clamp body extending between a proximal end and a distal end and comprising first and second clamping members having first and second opposing surfaces, the clamping members movably mated with one another proximate to the distal end of the clamp body, the clamping members mated with first and second shafts; moving the first shaft relative to the second shaft to cause the clamp to move relative to the second shaft; and moving the first shaft relative to the second shaft to move the first clamping member relative to the second clamping member.
