A cardiovascular prosthetic valve includes a cuff having a distal end and a proximal end. An inflatable structure is coupled to the cuff and has at least one inflatable channel that forms a toroidal structure. A valve is coupled to the cuff; the valve configured to permit flow in a first axial direction and to inhibit flow in a second axial direction opposite to the first axial direction. In one arrangement, the distal end of the cuff has a non-circular cross-section with respect to the flow and the non-circular cross-section is configured to affect the performance of an adjacent valve. In another arrangement, the cuff includes an anchor moveable from a first position to a second position. In another arrangement, control wires are coupled to the cuff.

A female piercing member protection device for connection with a male connection part, and a method for connecting the device to a male connection part. The device includes an outer casing and a connection member at least partly enclosed in the outer casing. The outer casing is moveable between first and second positions. In the first position, the connection member is substantially locked from movement along the longitudinal axis A, and in the second position the connection member is able to move along the longitudinal axis A. The device also has an activated position and an inactivated position. When the outer casing is in the second position, a deformable locking device is prevented from deformation by the outer casing to prevent disengagement of the male connection part. A secure piercing member protection device significantly minimizes the risk for a user to be exposed to contaminants and the piercing member itself.

An intervertebral disc replacement prosthesis which can be implanted in a collapsed state, then expanded within the disc space such that minimally invasive surgical techniques may be employed for its insertion, and, by virtue of its expandable nature, ligaments can be restored to proper tension, facet joints can be unloaded posteriorly to inhibit degenerative changes, and functional mobility of the intervertebral segment can be restored.

The present invention concerns a female piercing member protection device for connection with a male connection part, as well as a method for connecting such protection device to a male connection part. The female piercing member protection device comprises; an outer casing, a connection member wherein the connection member is arranged to, and at least partly enclosed in, the outer casing. Further is the outer casing arranged to be moved between a first and a second position, wherein when the outer casing is in its first position, the connection member is substantially locked from movement along the longitudinal axis A, and when the outer casing is in its second position the connection member is able to move along the longitudinal axis A. The female piercing member protection device also comprises an activated position and an inactivated position. The connection member is further arranged to connect to the male connection part by means of a deformable locking device, wherein when the outer casing is in the second position, the deformable locking device is prevented from deformation by the outer casing so as to prevent disengagement of the male connection part. The present invention provides for a secure piercing member protection device which significantly minimizes the risk for a user to be exposed to contaminants and the piercing member itself.

A method of implanting a prosthetic valve within the heart comprises translumenally advancing a prosthetic valve comprising an inflatable structure to a position proximate a native valve of the heart. A first chamber of the inflatable structure is inflated and then, independently, a second chamber of the inflatable structure is inflated.

A prone positioning therapeutic bed comprises a base frame, a patient support platform rotatably mounted on the base frame for rotational movement about a longitudinal rotational axis, a drive system for rotating the patient support platform on the base frame, and an upright end ring at the head of the bed with a central opening for routing patient care lines and a removable upper section for improved access to a patient's head. The patient support platform preferably has pivotally mounted side rails that fold underneath the patient support platform and straps with strap connectors that indicate whether the straps are sufficiently tensioned. A direct, wired electrical connection between the patient support platform and the base frame allows full rotation of the patient support platform in either direction. A manually operable lever disengages the patient support platform from the drive system to allow manual rotation of the patient support platform.
