Bone implants for the treatment of infection

Described herein are devices, systems and methods for treating disease and/or infection by the release of silver from an implant over an extended period of time. In particular, the devices described herein may be used to treat infections such as osteomyelitis by the controlled release of silver ions from multiple sites of an extended-use implant. This implant typically includes a plurality of arms that both anchor and help distribute the released ions within the tissue. Power may be applied to release the silver ions into the tissue.

METHODS OF SECURING A FASTENER
20220008101 · 2022-01-13 ·

Embodiments may include an attachable fastener, which may include a bondable material that may be secured to the end of an end effector. Vibration may be tuned to occur at a distal end of the fastener. Accordingly, the fastener may be used to generate heat at a distal point of contact. If the contact surface contains bondable material, that material may be softened. If the fastener includes bondable material at the point of contact, that material may also be softened by heat produced by vibration at the contact area. A hard implant or another polymeric material may function as the anvil.

The guidance and positioning device may be a system for creating a passage in tissue, positioning fasteners or other implants, and tensioning an elongated fastening member, like a suture, thread, wire, or pin. In some embodiments, the device may allow for the implantation of multiple sutures and fasteners in tissue. A fastener may be positioned at the distal end of a flexible pushrod. The fastener may be connected with the pushrod or may be loosely fitted with the distal end of the pushrod. A suture may be looped through or connected with the fastener such that one, two, or more sections, legs, strands, or portions of the suture extend from the fastener.

INTERVERTEBRAL IMPLANTS AND RELATED METHODS OF USE

A method of implanting an intervertebral spacer may include positioning the intervertebral spacer within an intervertebral space defined by adjacent vertebral bodies. The intervertebral spacer may include a plurality of bores, and each of the plurality of bores may be configured to receive either a linear fastening element or a curvilinear fastening element. The method also may include selecting a first fastening element from a group including linear fastening elements and curvilinear fastening elements, and inserting the first fastening element into a first bore of the plurality of bores such that the first fastening element is inserted into one of the adjacent vertebral bodies to secure the intervertebral spacer within the intervertebral space.
