Abstract: A system (30) for dispensing curable material. A lead screw (62) is rotatably fixed relative to a first control surface (60) and includes external threads (94). A locking nut (90) includes internal threads (92) threadably engaging the external threads. An engagement feature (98) of the locking nut is adapted to be selectively engaged with an actuator (120) having a second control surface (122). The threads provide for rotation of the locking nut about a translation axis when the actuator is in a disengaged position. Rotation of the locking nut permits the lead screw to move proximally along the axis and the compressed curable material to at least partially decompress within a dispensing volume. The threads further provide for distal advancement of the lead screw along the axis when the actuator is in an engaged position rotatably fixing the locking nut about the axis. Methods for operating and packaging the curable material dispensing system are also described.

Abstract: A stabilization system and implant for preventing relative motion between tissue sections of a patient, for example, an ilium and a sacrum defining a sacroiliac joint. The stabilization system comprises an implant comprising an elongate trunk, a proximal anchor configured to be positioned within the ilium, and a distal anchor configured to be positioned within the sacrum. The proximal anchor comprises a deformable feature configured to engage the ilium and the distal anchor comprises an expandable member configured to engage the sacrum. The stabilization system further comprises a tool removably coupled to the anchor to insert the implant in the patient and selectively engage the anchors with the respective bones. The implant is configured to be implanted through a minimally invasive incision.

Abstract: A minimally invasive bone stabilization system for preventing relative motion between a first bone (122) and a second bone (124) comprises an insertion tool (30) comprising a driver (52) configured to receive a rotational input, a first shaft (46) comprising a distal end and engagement features (47) near the distal end, a second shaft (60) disposed within the first shaft (46) with the second shaft (60) comprising a proximal end coupled to the driver (52), and a distal end opposite the proximal end, and drive features (64) near the distal end. The system further comprises an implant (76) adapted to be removably coupled to the insertion tool (30) and comprising an elongate trunk (90) defined between a distal end and a proximal end, a longitudinal axis (300) defined between the proximal and distal ends, a periphery defined by an outer surface of the elongate trunk (90), driven features (89) coupled to the elongate trunk (90) and configured to engage the drive features of the insertion tool (30), and a proximal anchor (86) configured to engage the first bone (122) and comprising a deformable feature (310) adapted to deform in response to a compressive load, thereby extending at least a portion of the deformable feature (310) beyond the periphery of the elongate trunk (90) relative to the longitudinal axis to engage the first bone (122). The implant (76) further comprises an engagement feature (81) coupled to the elongate trunk (90) and configured to engage the engagement features (47) of the insertion tool (30) to prevent rotation of the elongate trunk (90) relative to the insertion tool (30) such that, in response to the driver (52) receiving the rotational input and with the complimentary engagement features (47, 81) and the complimentary drive features (64, 89) engaged, the compressive load is provided to the implant (76) along the longitudinal axis (300).
