Devices and methods used to obtain a tissue sample utilizing a vacuum assist are disclosed. The devices include a handle, an inner cannula, and an outer cannula. The devices include a vacuum tube in communication with a sample notch of the inner cannula. The handle is actuated to drive the inner cannula into a lesion such that the sample notch is disposed within the lesion. A vacuum is generated in the vacuum tube and the sample notch as the stylet is driven into the lesion. A tissue sample is sucked into the sample notch and the outer cannula is displaced over the sample notch to sever the tissue sample from the lesion.

Systems, methods and devices are disclosed for facilitating assembly and use of spinal fixation apparatus, including a helical cage structure for selective engaging and/or securing an engagement member or surgical screw in a spinal fixation system.

Spring cage spinal fixation systems

Spinal fixation apparatus with a first end for selectively flexing to expand in diameter when receiving a head of an engagement member, the engagement member for coupling to a portion of a spine and a flexible sidewall between the first end and a second end, the flexible sidewall to selectively expand in length, between the first end and the second end, when the first end is not in receipt of the head of an engagement member and alternatively to contract in length when the first end is in receipt of the head of the engagement member.

Spinal fixation system connectors comprising spring cage elements. In some embodiments, an engagement member, such as a bone screw, may be configured to be coupled with and received within a connector body. A spring cage structure may also be configured to be coupled with the connector body. The spring cage structure may comprise a spring configured to be positioned in a relaxed configuration and a flexed configuration, such that the spring defines an opening having a first size in the relaxed configuration and a second, larger size in the flexed configuration to allow the opening to receive and engage a head of the engagement member within the connector body.

Biomedical implants comprising portions made of disparate materials, such as intervertebral implants and related methods and instruments. In some embodiments, the implant may comprise a base portion comprising a first material and a secondary fastener portion comprising a second material having distinct physical properties relative to the first material. The secondary portion may wholly define a front end wall surface of the implant, and the base portion and the secondary portion may collectively define at least one of an upper surface and a lower surface of the implant.
