Abstract:
A low-profile, self-expanding vascular stent which is preferably cut from a thin tubing. The stent includes helical windings in a single helix, which are joined by bridges for longitudinal and radial strengthening.
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:
A patent foramen ovale closure device, method of delivering and a delivery system are provided. The device may include a closure device releasably connectable to an actuator. The device may include a proximal segment, an intermediate segment and a distal segment. When delivered, the proximal segment and intermediate segment form a first clip-shaped portion sized and configured to be positioned over a septum secundum of the patent foramen ovale, and the intermediate segment and distal segment form a second clip-shaped portion sized and configured to be positioned over a septum primum of the patent foramen ovale.

Abstract:
An apparatus for delivering a medical device onto a heart includes a housing within which is releasably disposed the medical device. The housing in one embodiment comprises inner and outer deflectors between which is delivered the medical device. Both deflectors are self-expanding. A deflector compression sheath is slidable longitudinally over the housing to a delivery position at which it moves the deflectors to a collapsed configuration. The compression sheath is retracted to a deployment position to permit the deflectors to deploy by self-expanding to their larger diameters. The outer deflector has an expanded diameter sufficient to engage the inner surface of the pericardium to hold it away from the delivery site while the second deflector guides the medical device into position over the heart while protecting the heart. In another embodiment, the housing includes only an outer deflector. The apparatus also functions as an introducer when the compression sheath is moved to the delivery or “introducer” position at which configuration, the apparatus functions as an introducer.
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:
An apparatus for delivering a cardiac harness onto a heart includes an elongate body and a plurality of elongate push rods longitudinally movable with respect to the elongate body. The elongate body has a tubular housing that is sized to contain the cardiac harness which is removably attached to the push rods. The cardiac harness is releasably attached to the push rods such that advancement of the push rods in a distal direction moves the cardiac hearness from a compacted configuration in the housing to an expanded configuration outside the housing. A deflector is attached to the elongate body and is configured to flare radially outwardly. As the push rods advance out of the housing, the push rods slide over the deflector to more easily and safely advance over the enlarged heart and position the cardiac harness over the heart.

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.
