Abstract: Disclosed is an adjustable occlusion device for use in a body lumen such as the left atrial appendage. The occlusion device is removably carried by a deployment catheter. The device may be enlarged or reduced to facilitate optimal placement or removal. Methods are also disclosed.

Abstract: Methods and devices are disclosed for manipulating the tongue. An implant is positioned within at least a portion of the tongue and may be secured to other surrounding structures such as the mandible and/or hyoid bone. In general, the implant is manipulated to displace at least a portion of the posterior tongue in an anterior or lateral direction, or to alter the tissue tension or compliance of the tongue. Methods and devices are also disclosed for manipulating other soft tissue structures, including the soft palate and pharyngeal airway.

Abstract: Disclosed is a closure catheter, for closing a body cavity such as a vessel, or the left atrial appendage of the heart. The closure catheter includes a plurality of deployable tissue anchors, which may be laterally deployed into surrounding tissue. The anchors may thereafter be used to draw the tissue radially inwardly, to close the body cavity. Methods are also disclosed.

Abstract: Disclosed is an anastomosis catheter, for achieving a tissue to tissue or synthetic graft to tissue attachment. The catheter includes a plurality of deployable tissue anchors, which may be laterally deployed into surrounding tissue. The anchors may be used to achieve end to end or end to side anastomoses. Methods are also disclosed.

Abstract: Methods and devices are disclosed for manipulating the hyoid bone, such as to treat obstructive sleep apnea. A conformable implant is positioned adjacent a hyoid bone. The spatial orientation of the hyoid bone is manipulated, to affect the configuration of the airway. The implant restrains the hyoid bone in the manipulated configuration. The implant is positioned adjacent to pharyngeal structures to dilate the pharyngeal airway and/or to support the pharyngeal wall against collapse. The implant may be attached to the hyoid bone using a clamp delivery tool that is adapted to releasably engage the implant.

Abstract: Methods and devices are disclosed for manipulating the airway, such as to treat obstructive sleep apnea. An implant is positioned within the body with respect to the airway. The spatial orientation of the airway is manipulated, directly or indirectly, to affect the configuration of the airway. In general, the implant is manipulated to displace the trachea in an inferior direction, resist superior displacement of the trachea and/or to alter the tracheal wall tension. The implant restrains the trachea in the manipulated configuration.

Abstract: Disclosed is an apparatus for facilitating access to the left atrium, and specifically the left atrial appendage. The apparatus may comprise a sheath with first and second curved sections that facilitate location of the fossa ovalis and left atrial appendage. The apparatus may further comprise tissue piercing and dilating structures. Methods are also disclosed.

Abstract: A device for everting an end of a hollow tissue structure may include a mandrel and a collar proximal to the mandrel. The mandrel may be elastomeric and deformable. At least one of the collar and the mandrel may be movable relative to the other. Deformation of the mandrel everts the end of the hollow tissue structure.

Abstract: A patent foramen ovale closure device and method are provided. The device is deployed at the foramen ovale to secure the septum primum and septum secundum together, thus sealing the foramen ovale. A countertraction element is provided to hold the patent foramen ovale together while the device is being deployed, to ensure adequate positioning of the closure device.

Abstract: An everter and threadthrough system useful for attaching a graft vessel to a anastomosis device which can be used to attach a graft vessel to a target vessel without the use of conventional sutures. The threadthrough system engages an end of the graft vessel and pulls the graft vessel through a deployment tool until a portion of the graft vessel extends beyond a distal end of the anastomosis device mounted on the deployment tool. The everter includes a spreading mechanism which expands the end of the graft vessel and folds the expanded end over the anastomosis device. In the case where the anastomosis device includes barbs, the everter can effect penetration of the graft vessel by the barbs. Once the graft vessel is everted over the anastomosis device, the deployment tool can be used to attach the graft vessel to a target vessel.

Abstract: Disclosed is a closure catheter, for closing a tissue opening such as an atrial septal defect, patent foreman ovale, or the left atrial appendage of the heart. The closure catheter carries a plurality of tissue anchors, which may be deployed into tissue surrounding the opening, and used to draw the opening closed. Methods are also disclosed.

Abstract: A device for containing emboli within a left atrial appendage of a patient includes a frame that is expandable from a reduced cross section to an enlarged cross section and a slider assembly. The frame extends between a proximal hub and a distal hub, and the slider assembly is coupled to the distal hub of the frame. The slider assembly includes a guide tube that has a channel extending proximally away from the distal hub, and a nut. The nut is longitudinally moveable within the channel of the guide tube over a predetermined distance relative to the guide tube. The nut is operable to be releasably coupled with an elongate core, and movement of the nut relative to the guide tube is at least partially limited by interference between a portion of the nut and a portion of the guide tube.

Abstract: Disclosed is an occlusion device for use in a body lumen such as the left atrial appendage. The occlusion device includes an occlusion member and may also include a stabilizing member. The stabilizing member inhibits compression of the left atrial appendage, facilitating tissue in-growth onto the occlusion member. Methods are also disclosed.

Abstract: An information and redemption system that actively uses targeted and highly personalized e-mail messages to develop and strengthen the affinity between a merchant and the merchant's patrons and potential patrons. Unlike other computer-based marketing systems which passively wait for patrons to visit a web site, the present invention uses an active “push” approach to allow merchants to affirmatively approach those patrons interested in goods, services, or information relating to the merchant. Unlike other direct marketing systems, only patrons who “opt in” to the system participate, and all patrons are free to “opt out” any time. The present invention relies on providing patrons value with each e-mail such that the relationship between merchant and patron is strengthened. The present invention anticipates that the existence of information clearinghouses that can be separate and distinct from merchants.
