The nucleus of an intervertebral disc is replaced with a construct including a distendable sack or balloon which is inflated with a hardenable material and is detached in situ when the injected material has hardened. Alternatively, two nested balloons may be inserted, and then filled with materials which have different hardnesses when cured, to simulate a natural disc.

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 semiconductor device includes a semiconductor substrate and an array of protruding electrodes arranged at a pitch X1. Each of the protruding electrodes has a height X3 and is formed on a barrier metal base of diameter X2 coupled to an electrode arranged on the semiconductor substrate so as to satisfy the relations (X1 / 2)≦X2≦(3*X1 / 4) and (X1 / 2)≦X3≦(3*X1 / 4).

An intervertebral prosthesis, in particular for the cervical spine, has two attachment plates connected in an articulated manner. The attachment surfaces of the attachment plates, which are configured for attachment to adjacent vertebral bodies have a base surface configured to bear on the surface of the vertebral bodies, and self-tapping fixing projections rising from the base surface. These fixing projections are formed by at least one pair of ribs which extend in opposite directions obliquely with respect to a predetermined implantation direction and whose side faces oriented more away from the implantation direction are steeper than their side faces oriented more in the implantation direction. The ribs can be toothed.

A mounting device for securing plate-shaped elements (5) on a mounting rail (6) includes first (12; 52; 72) and second holding members (17; 57; 77) forming, together a space (16; 42) for receiving a plate-shaped element (5), a fastening member (27; 60) extending through the first (12; 52; 72) and the second (17; 57; 77) holding member and connectable with an anchoring element (23) provided on the mounting rail (6) for securing the mounting device (11; 41; 51; 71) on the mounting rail (6), and at least one resilient element (32; 46; 62; 92) provided between the first holding member (12; 52; 72), which is displaceable relative to the second holding member, and the second holding member (17; 57; 77) for spacing the first and second holding members (12, 17; 52, 57; 72, 77) from each other.

A shelter or camper that provides improved portability and protection. The shelter or camper may include rigid walls to offer greater protection from weather, animals, and theft. The shelter or camper may be transitionable between different configurations for different purposes, including an open and expanded configuration for use as a shelter, camper, or sleeping quarters and a compact, closed case configuration for easy storage and transport. To facilitate this, the walls may be foldable, expandable, or collapsible. When the walls are folded or collapsed, roof and floor sections may be connected to each other and may enclose the folded, collapsed walls and internal components within the collapsed closed case.

A method is disclosed for introducing a spinal disc implant into an intervertebral space of a subject. The subject is placed in a lateral position, and the anterior face of the spinal disc intervertebral space is accessed, between the L5 and S1 vertebrae, from an anterior and lateral retroperitoneal approach. An operative corridor to the anterior face of the spinal disc space is established by introducing a retractor instrument anterolaterally to the spinal disc space between the anterior superior iliac spine and the anterior inferior iliac spine. The damaged spinal disc contents are removed from the intervertebral space through the operative corridor, and the implant is advanced into the intervertebral space at an oblique angle and pivoted to position the implant substantially laterally within the intervertebral space. Elongated retractor and insertion instruments, as well as a modified disc implant, are also disclosed for carrying out the method.

A package assembly 10 for the storage and distribution of a plurality of stacked mints 12 is provided. The package assembly 10 includes a cylindrical outer shell 14 including a shell sidewall 16, a shell bottom surface 18, and a shell open top 20. The shell sidewall 16 includes a sidewall inner surface 22 and a sidewall outer surface 24. A vertical control slot 28 is formed in the shell sidewall 16, the vertical control slot 28 having a control slot height 40 and a control slot width 42. At least one retention protrusion 78 is formed onto a slot side edge 34 such that the control slot width 42 is reduced in the location of the at least one retention protrusion 78. A cylindrical inner insert 26 including an insert sidewall 44, an insert top surface 46, and an insert open bottom 48, is formed to house the plurality of stacked mints 12. The cylindrical inner insert 26 is positioned within the cylindrical outer shell 14 such that the insert open bottom 48 faces the shell bottom surface 18. A control pad 52 is formed onto and protrudes outwards from the insert sidewall 44. The control pad 52 is positioned within the vertical control slot 28 and is movable such that the cylindrical inner insert 26 can be moved between a closed position 68 and an open position 70. The control pad 52 has a control pad width 54 such that said control pad 52 engages the at least one retention protrusion 78 when in the closed position 68 and such that the cylindrical inner insert 26 is resisted from moving into the open position 70. A dispensing chamber 72 is formed in the insert sidewall 44 adjoining the insert top surface 46. The dispensing chamber 72 is covered by the shell sidewall 16 when the cylindrical inner insert 26 is in the closed position 68. The dispensing chamber 72 is positioned outside the cylindrical outer shell 14 when the cylindrical inner insert 26 is in the open position 70. The dispensing chamber 72 has a dispensing chamber height 74 sufficient to allow one of the plurality of stacked mints 12 to be removed from the cylindrical inner insert 26.
