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.

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.

A braided stent to be implanted in a blood vessel comprises a hollow body which is stretchable in its longitudinal direction and whose circumferential surface is formed by a braid of a multiplicity of filamentary elements which, in the expanded state of the braided stent, intersect a plane, perpendicular to the longitudinal direction, at a braiding angle. The braided stent has a smaller braiding angle in a central portion than in its distal and proximal portions which adjoin the central portion in the longitudinal direction.

A leadless cardiac pacemaker comprises a housing, a plurality of electrodes coupled to an outer surface of the housing, and a pulse delivery system hermetically contained within the housing and electrically coupled to the electrode plurality, the pulse delivery system configured for sourcing energy internal to the housing, generating and delivering electrical pulses to the electrode plurality. The pacemaker further comprises an anti-unscrewing feature disposed on either a fixation device of the pacemaker or on the housing itself. The anti-unscrewing feature can be configured to prevent the fixation device from disengaging the wall of the heart.

Load transport and retraining devices and methods for restraining industrial machines or heavy machinery, such as, turbines, to prevent displacement during adverse environmental conditions, such as, pitching and rolling seas, are provided. The devices include support structures adapted to support loads and having wheels positioned and adapted to engage rails. The wheels include a first set of wheels adapted to ride on top of the rails and a second set of wheels adapted to engage the sides of the rails and thereby retain the support structure to the rails. The devices may also include a third set of wheels adapted to also engage the sides of the rails. The devices may include brake and drive assemblies to facilitate handling. Aspects of the disclosure are uniquely adapted to turbines, but other aspects of the disclosure may restrain any industrial machine that may be exposed to adverse environmental conditions.

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 plurality of wire-rod product support-and-display accessories are removably supported between the attachment rods and span the at least two vertical side frames. A plurality of these racks may be disposed side-by-side to form a large flexible display structure.

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 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.

The present invention provides a vascular prosthesis featuring a plurality of modular segments interengaged by flexible, and preferably lockable, inter-engageable elements forming joints.
