A posterior fixation system includes a saddle member and an anchoring member. The anchoring member anchors the saddle member to bone. The saddle member includes a pair of upright portions that define a channel. The saddle member further has a hole therethrough bounded by an inner wall, and the hole forms a lower opening in the saddle member. The lower opening in the saddle member may contain angular cutouts placed symmetrically about the axis of the saddle to increase the allowable angulation of the bone screw in relationship to the axis of the saddle. The channel is adapted to receive an orthopedic rod, and the hole in the saddle member is adapted to receive the anchoring member. The saddle member and the anchoring member can be coupled so as to allow multi-axial movement of the members.

A tool for use during surgery includes a housing including a distal end and a proximal end, a motor disposed within the housing, and an output shaft having a proximal end connected to the motor and a distal end extending from the distal end of the housing. The tool further includes a battery pack contained within the housing, and a passage extending from the distal end to the proximal end of the housing through the output shaft and the battery pack, wherein the passage is defined by an interior surface of the output shaft and a channel through the battery.

Devices and methods to grasp a medical element. The device may include a first member, a second member that fits within the first member, and a locking element. The first and second members may move relative to one another to move the locking element between locked and unlocked positions. In an unlocked position, the device may move along the element. In the locked position, the device may lock to the element and motion is prevented. In one application, the device can be placed in the locked position to maintain a desired amount of tension on the element.

System and methods are provided that include a plate member engageable to the spinal column with an anchor assembly. The anchor assembly includes a coupling member having a post extending through at least one opening of the plate member and an anchor member pivotally captured in a receiver member of the coupling member below a lower surface of the plate member. A locking member secures the plate member to the coupling member.

Naturally occurring and/or modified Clostridium neurotoxins, including those neurotoxins free of complexing proteins which naturally form complexes with Clostridial neurotoxins, are used to enhance healing of injured surface or superficial tissue of a patient by local administration into or in close proximity to the injured tissue. Such neurotoxins may be advantageously employed in wound healing and preventing scar formation, and find applicability in the area of ophthalmology, e.g. in treatment of injured corneal tissue, for example by closing inflamed eyes. A further embodiment includes diagnostic usage for the evaluation of effective toxin administration and medicaments for use therein.

An efficiently folding hard-bonnet dryer, which can be folded down to only six inches in standing height. This improved design is effected in part by rotating the lower half of the hard bonnet on an axis through the center of the bonnet, and also by telescoping the neck and arranging a pair of motors and a heater in an efficient geometry to span the folded neck.

A surgical tool includes a drive assembly including a head assembly and a cutting assembly coupled to the drive assembly. The cutting assembly includes a first blade having a first cutting surface and a first contact surface. The cutting assembly also includes a second blade pivotally coupled to the first blade. The second blade has a second cutting surface and a second contact surface. The first and second contact surfaces define a constant travel ratio

An implant for insertion between vertebral members in which an inner member, intermediate member, and outer member are concentrically disposed. The inner and outer members may comprise end plates to contact the vertebral members. The outer member may include a tapered interior wall. A locking element is movably contained within an opening that extends through a sidewall of the intermediate member. The intermediate member is displaceable longitudinally in first and second directions relative to the outer member. Displacement of the intermediate member in the first direction tends to force the locking element laterally into contact with the inner and outer members. A biasing member may urge the intermediate member in the first direction. Displacement of the intermediate member in the second direction allows the locking element to be laterally displaced out of contact with the inner member.

There is provided a showerhead device that includes a shower stem connector, a water/air mixing chamber, and an outlet cap. The shower stem connector includes a water inlet to receive water from a standard shower plumbing system and an air intake opening to receive air from outside the device. The preferred embodiment features an air intake opening located near the water inlet on the shower stem connector. A user can adjust the air intake knob in order to vary the amount of air that enters the device and mixes with the water flow. As the water progresses through a nozzle in the device, the speed of the water is increased by the decrease in diameter of the nozzle orifice. The water mixes with the air and the combination of water/air hits a plate on the inner wall of the outlet cap within the mixing chamber. This oxygenation of the water provides for a better water flow though the showerhead device. The mix of water and air provides for a stronger water flow and a better shower experience for a user. By having the air intake further upstream, it enables a user to adjust the amount of air mixed in.

A surgical instrument and method for forming a passage in bone having an enlarged cross-sectional portion is provided. The instrument includes an elongate member and a cutting element engaged thereto and transitionable between a retracted configuration for extending through a first portion of the passage and an expanded configuration for forming a second portion of the passage having an enlarged cross-section. In one embodiment, the cutting element is transitioned between the retracted and expanded configurations by axially displacing the cutting element relative to the elongate member. In another embodiment, the elongate member includes a tapping thread configured to cut threads along the first portion of the passage, and the cutting element is a blade configured to form the enlarged cross-section when transitioned to the expanded configuration. In another embodiment, the cutting element is arranged in an axial orientation when in the retracted configuration and an angular orientation when in the expanded configuration.
