An implantable device for control over the size of emphysematous bullae in a lung, including: an elongated central region having a fixed axial length; a first end including a first anchor; and a second end including a second anchor.

Methods and devices for controlling the size of emphysematous bullae

A device and method for reducing the volume of a tissue region, the device including a first fixation element, a second fixation element, and a tethering device, where the first and second fixation elements are slidably secured onto said tether, and the first and second fixation elements are radially self-expanding fixation elements.

Mechanical retraction via tethering for lung volume reduction

The present invention relates to a delivery system for delivering a device for closing a passageway in a body, for example a patent foramen ovale (PFO) in a heart. The delivery system has an elongate member having a proximal and distal end. A deflectable needle assembly having luminal and abluminal surfaces is slideably engaged within the elongate member. An actuator is slideabley engaged within the elongate member and attached to the needle tip assembly such that translational movement of the actuator causes deflection of the deflectable needle assembly.

Patent foramen ovale closure device with steerable delivery system

A device and method for deploying a mechanical closure device for closing a passageway in a body, for example a patent foramen ovale (PFO) in a heart. The single disc mechanical closure device is comprise of a distal and proximal anchor constrained by a closure line to facilitate mechanical closure by bringing the distal and proximal anchors into close proximity along the closure line.

Single disc intraluminal fixation patent foramen ovale closure device

A system and method for the treatment of mitral valve regurgitation by reshaping the mitral valve annulus using one or more plications of annular or adjacent tissue each fixed by a retainer is described. The system includes four devices to achieve such percutaneous direct plication annuloplasty. The first is a crossing catheter having a prolapseable or curved tip. Second, a deflecting guide catheter is used to provide a means for guiding the plication device into proper position at the subvalvular region of the mitral valve annulus. Third, the plication device is then used to make plications in the subvalvular region of the mitral valve annulus. Fourth, a 'C' shaped retainer with deformable ends is deployed by the plication device in order to retain the plicated tissue in the plicated form. A transseptal approach may be used to plicate and retain tissue on the atrial side of the mitral valve to achieve a reduction in mitral valve regurgitation.

Method and system for plicating tissue in a minimally invasive medical procedure for the treatment of mitral valve regurgitation

A deflecting guide catheter for use in minimally invasive medical procedures such as the treatment of mitral valve regurgitation by reshaping the mitral valve annulus using one or more plications of annular or adjacent tissue each fixed by a retainer is described. The catheter includes an elongated tubular portion having various durometers along its length and at least one puller wire attached to an anchor band near the distal end. The deflecting guide catheter is used to provide a means for guiding a plication device or other medical instrument into a desired position within the vasculature or heart chambers of a patient.

A steerable guidewire having a deflectable distal tip which comprises a longitudinal hypotube and an interlocking spring coil attached to the distal end of the hypotube and also includes a longitudinally movable deflection member which is attached to the distal end of the spring coil and a tip retaining ribbon which extends from the distal end of the hypotube to the distal end of the spring coil for providing very precise deflection of the distal tip. The distal end of the deflection member has 'skived,' or tapered, sides to enhance the flexibility of the guidewire.
