Abstract:
Embodiments relate generally to tissue anchors and methods of deliveπng same to the intervertebral disc or other sites within the body. In some embodiments, the anchors provide increased pull-out resistance, stability and/or contact with tissue involving a reduced amount of penetration. In some embodiments, delivery methods are minimally invasive and can include linear, lateral, and off-angle implantation or driving of anchors along, against or within tissue surfaces. Several embodiments disclose anchors and anchoπng systems that effectively reconstruct or augment vertebral endplate surfaces.
Abstract:
Devices and methods for performing intrvenous vascular procedures without cardiac bypass. The devices include various embodiments of temporary filter devices (10), temporary valves (26, 100), and prosthetic valves (80, 85, 86, 90). The temporary filter devices (10) have one or more cannulae (2) which provide access for surgical tools for effecting repair of the cardiac valves. A cannula (2) may have filters (3) of various configurations encircling the distal region of the cannula, which prevents embolism material from entering the coronary arteries, and aorta. In one embodiment, a set of valve leaflets (70, 71) extend peripherally from the filter to prevent blood flow through peripheral arteries. The temporary valve devices (26) may also have one or more cannulae (2') which guide insertion of the valve into the aorta. The valve devices (26) expand in the aorta to occupy the entire flow path of the vessel. In one embodiment, the temporary valve (26) is a disc of flexible, porous material that acts to filter blood passing therethrough. In another embodiment, the temporary valve (100) has leaflets (111) which act in concert to alternately block or allow blood flow.

Abstract:
Devices and methods are disclosed for extracting fluids from a container sealed by a cork or septum without removal of the cork or septum or the contamination of the fluid within the container by reactive gases. Embodiments of the device can include a needle (200) connected to a valve (300) and connected to a source of pressurized gas (100) for displacing the fluid. Further embodiments can comprise additional components that act to insert the needle (200) through the cork of septum along a linear path, to prevent buckling of the needle (200), to clamp the device to the container, to prevent expulsion of the cork or septum from the container and to guide the needle (200) through a specified region of the cork septum. Various valves, pressure regulators, pressure gages, needle geometries, gas selections are also presented. The device is particularly suited for the dispensing and preservation of wine.
Abstract:
The present invention relates generally to devices and methods for delivering medical devices, such as implants (100), to desired tissue sites, such as the intervertebral disc (315). In one aspect, an intervertebral disc repair and diagnostic device that is minimally invasive and that provides precise access to the desired site is provided. In some aspects, the device and method are adapted to deliver, position and expand implants that are initially oriented and compressed for minimally invasive, yet precise and effective implantation.

Abstract:
A vertebral disc prosthesis (50), a method for implanting and a deployment device (80) is provided. The prosthesis (50) is for deployment within the interior of the vertebral disc for restoring the functionality of the disc (e.g., the ability of the disc to transfer nutrients or otherwise survive, the ability of the disc to carry the required loads and absorb stress or the reduction of pain). The prosthesis (50) may be made of a material having a compression strength less than about 4 mn/m 2 and may include a grouping of multiple components that can be deployed as group.

Abstract:
Devices and methods are disclosed for extracting fluids from within a container sealed by a cork or septum without removal of the cork or septum or the contamination of the fluid within the container by reactive gases or liquids. Embodiments of the device can include a needle (200) connected to a valve (300) which is in turn connected to a source of pressurized gas (100) for displacing the fluid. Further embodiments of the device can comprise additional components that act to force the needle to be inserted through the cork or septum along a linear path, to aid in preventing buckling of the needle, to clamp the device to the container, to prevent expulsion of the cork or septum from the container, and to guide the needle through a specified region of the cork or septum. Various valves, pressure regulators, pressure ranges, needle geometries, gas selections are also presented. This device is particularly suited for the dispensing and preservation of wine.
