A load sensing assembly for a spinal implant is disclosed. The load sensing assembly may include: a set screw having a drive interface, a lower cavity for receiving a cover, the cover including a protrusion that may engage with an anchoring member. The load sensing assembly may further include an antenna, and at least one sensor having an integrated circuit in communication with the antenna. In some embodiments, the integrated circuit is positioned within a sealed cavity of the set screw. In some embodiments, a connecting wire extends through a through hole of the set screw and into the sealed cavity to connect the antenna with the at least one sensor. In some embodiments, the cap is welded to the set screw, the through hole is filled with an insulative material, and the sealed cavity of the set screw is hermitically sealed.

Modular set screw design for housing microelectronics

Embodiments pertaining to a medical construct are disclosed. The medical construct may include a set screw extending along a longitudinal axis between a proximal portion and a distal portion, for example. In various embodiments, the set screw may have an outside thread form and an interior socket, for example. In various embodiments, the socket may extend parallel to the longitudinal axis and have a circular lower surface, for example. In various embodiments, a first strain gauge, a second strain gauge, a third strain gauge, a fourth strain gauge, and a fifth strain gauge may be provided. In at least some embodiments, each of the first, second, third, and fourth strain gauges may be symmetrically disposed with respect to the lower surface, for example. Additionally, in at least some embodiments, the fifth strain gauge is disposed within a center portion of the lower surface, for example.

Set screw with strain gauges

A spinal implant includes an intermediate portion and a first portion extending in a transverse orientation from the intermediate portion. The first portion includes an inner surface connectable with vertebral tissue adjacent a lamina. A second portion is spaced from the first portion and extends in a transverse orientation from the intermediate portion. The second portion includes an inner surface connectable with vertebral tissue adjacent a lamina. At least one of the first portion and the second portion includes an outer surface having a mating element engageable with a mating element of a surgical instrument. Systems, surgical instruments and methods are disclosed.

Spinal implant system and methods of use

A spinal correction system comprises a first member configured for attachment to a first portion of vertebral tissue and a second member is configured for attachment to a second portion of the vertebral tissue spaced from the first portion. A third member has a non-flexible configuration relative to the first and second members and is configured for attachment to an apical portion of the vertebral tissue and along at least a portion of at least two vertebrae. The third member extends between a first end connected to the first member at a first transition configured for attachment to the first vertebral tissue and a second end connected to the second member at a second transition configured for attachment to the vertebral tissue. Methods of use are disclosed.

Spinal correction system and method

A medical implant device has in one embodiment a receiver member for receiving an elongated member, a crown member, an anchor member and a retaining member. An embodiment of the receiver member has an axial opening, a transverse channel, a chamber including at least one substantially flat wall, and a groove. An embodiment of the crown member has at least one substantially flat side. An embodiment of the anchor member has a head with at least one substantially flat surface that may be parallel to the anchor member's longitudinal axis, and an anchoring portion. An embodiment of the retaining member is a substantially flat clip. The crown member and anchor member are inserted into the chamber, and the retaining member is inserted into the groove beneath them. The anchor member may be pivoted substantially in one plane with respect to the receiver member until locked.

Adjustable bone anchor assembly

A fusionless correction system comprises a longitudinal element extending between a first end and second end. At least one fixation element is disposed with the longitudinal element and is configured for disposal in bone. A lock is disposed with the at least one fixation element and includes at least one bone penetrating projection. The lock is movable relative to the at least one fixation element between a first non-engaging configuration and a second engaging configuration such that the at least one bone penetrating projection extends beyond an outer surface of the at least one fixation element. Methods of use are disclosed.

This invention relates to interconnection assemblies for use with spinal fixation systems to treat spinal defects. The interconnection assemblies can include various spinal rod connecting members and interconnecting elements to secure the spinal rod connecting members to each other in variable orientations and lengths. The interconnection assemblies can be adjusted to minimize interference with the spinal column, bony processes, and associated neural, muscular, and ligament components of the spine all the while exhibiting a low profile. The interconnecting elements and related components can be provided as a completely assembled unit that does not inadvertently become disassembled prior to or during implantation.

Multi axial cross link connector system for spinal implants

Multi-axial, cross-link connector system for spinal implants

A bottom-loading multi-axial bone anchor apparatus is disclosed. The apparatus includes a receiver member, a crown member, a bone anchor and a retaining member. The receiver member defines an upper opening and a lower opening, which may form part of the same opening, a channel, and a groove. The crown member and bone anchor are loaded into the lower opening of the receiver member, and the retaining member fits around the bone anchor and into the groove in the receiver member. The bone anchor is capable of multi-axial positioning with respect to the receiver member. An elongated member is placed in the channel of the receiver member, contacting the crown member, and a compression member is applied via the upper opening. The compression member presses down on the elongated member, which presses down on the crown member and locks the bone anchor between the crown member and the retaining member.

Multi-axial bone screw assembly

A system for stabilization of the spinal column, including an elongate support member extending along an axis and a plurality of anchor members configured for anchoring to respective vertebrae. A first of the anchor members is engaged to the support member in a manner that substantially prevents axial movement of the support member relative to the first anchor member, and a second of the anchor members is engaged to the support member in a manner that allows substantially unconstrained axial movement of the support member relative to the second anchor member. In a further embodiment, a third of the anchor members is engaged to the support member in a manner that also allows substantially unconstrained axial movement of the support member relative to the third anchor member, with the second and third anchor members positioned on opposite sides of the first anchor member.
