Abstract: A surgical helmet assembly to be worn by a user during surgical operations. The surgical helmet assembly includes a frame assembly having a helmet shell to be worn over the user's head. A fan is coupled to the helmet shell to circulate air around the helmet shell. A headband assembly is coupled to the helmet shell to secure the surgical helmet assembly to the head of the user. The surgical helmet assembly further includes an adjustment assembly to adjust a sagittal fit of the helmet shell and the headband assembly to the head of the user while keeping a center of mass of the frame assembly in close proximity to the head of the user. The surgical helmet assembly may further include another adjustment assembly concentric to the first adjustment assembly to adjust a circumferential fit of the headband assembly to the head of the user.

Abstract: A surgical helmet assembly (30) to be worn by a user during surgical operations. The surgical helmet assembly includes a frame assembly (40) having a helmet shell (42) to be worn over the user's head. A fan (44) is coupled to the helmet shell to circulate air around the helmet shell. A headband assembly (78) is coupled to the helmet shell to secure the surgical helmet assembly to the head of the user. The surgical helmet assembly further includes an adjustment assembly (100) to adjust a sagittal fit of the helmet shell and the headband assembly to the head of the user while keeping a center of mass of the frame assembly in close proximity to the head of the user. The surgical helmet assembly further includes another adjustment assembly (118) concentric to the first adjustment assembly to adjust a circumferential fit of the headband assembly to the head of the user.

Abstract: A surgical garment worn by an individual. The surgical garment includes a sleeve having a distal end defining a lumen for receiving a hand and/or arm of the individual and a cuff portion disposed at the distal end of the sleeve. The cuff portion extends the lumen defined by the sleeve and further defines an opening. In addition, a barrier member is provided. The barrier member is disposed within the lumen proximal to the opening and configured to selectively prevent the hand of the individual from extending through the opening defined by the cuff portion.

Abstract: A spinal construct comprising a first portion. A second portion defines a longitudinal axis and is configured to penetrate tissue. A tether is fastened with the first portion such that a spinal implant connected with the tether is movable to a plurality of orientations relative to the longitudinal axis. Systems and methods are disclosed.

Abstract: Apparatus and methods include an elongate connecting element including a body extending along a longitudinal axis between a first end and an opposite second end. The connecting element includes a first end portion at its first end and a second end portion at its second end. The connecting element includes a length between the first and second ends sized to extend between and be engaged to first and second anchors engageable to bony portions of the spinal column. The first and second end portions are positioned on opposite sides of the first and second anchors and project outwardly from the body of the connecting element to capture the first and second anchors between the first and second end portions.

Abstract: A set screw for use in association with spinal implant assemblies. The set screw includes a threaded base portion extending along a longitudinal axis and formed of a first material, and a friction member extending from a distal end of the threaded base portion and formed of a second material different from the first material. In one embodiment, the spinal implant assembly includes a connector member having a passage and an opening in communication with the passage, and an elongate support member positioned within the passage of the connector member. The set screw is threadedly engaged to the connector member and at least partially positioned within the opening, with a distal end portion of the friction member extending into the passage and compressed against an outer surface of the elongate support member to inhibit movement of the elongate support member within the passage.

Abstract: A connector for connecting together elongated members in a side-by-side arrangement. The connector includes a first receptacle for connecting to the first elongated member, and a second receptacle for connecting to the second elongated member. The angular position of the second receptacle may be adjustable relative to the first receptacle to accommodate the elongated members. Further, the connector may be configured to extend between the elongated members and the patient when the connector is implanted in a patient.

Abstract: A bone anchor assembly and a rigid extension rod removably coupleable thereto. The bone anchor assembly includes a screw base and a pivoting post. The post has a first recess in a proximal endface thereof, which may have first threads therein. The extension rod has a distal section separated from a proximal section by an intermediate section. The rod distal section has external threads that are threadingly engageable with the threads of the post recess. The rod third section may have external third threads of a different size. The rod intermediate section has an unthreaded exterior. When the extension rod is coupled to the post, an exterior of the second section of the extension rod is aligned with the exterior of the post. Other connection approaches may be used. An optional spacer may also be used to couple the rod to the post.

Abstract: Bone anchors are provided that include a distal shaft for engaging bony structure of a vertebral body and a proximal post pivotably mounted at or near the proximal end of the shaft during implantation of the bone anchor. The bone anchors include a locking member that is engageable to the post and to the shaft to lock the post in a selected angular orientation relative to the shaft.

Abstract: Devices and methods include an anchor assembly engageable to a vertebra and a connecting element positionable through a receiver of the anchor assembly.
