An apparatus and methods for exerting force on a first bone with respect to a fulcrum, which may be a second bone. A base structure, mechanically coupled to the fulcrum, is coupled to the closure top so that a force may be exerted by the base structure, acting against the fulcrum, in at least one of axial and transverse directions with respect to a pedicle screw inserted into bone. A leg extension, allowing force to be applied through the pedicle screw to a bone, has a first end rotatably coupled to the base structure; and a second end threaded as the closure top. The base structure may also support a retractor in a manner local to the immediate region of surgery.

An improved utility cart for use in auto body repair facilities. The cart includes an upright frame from which one or more shelf or basket members extend generally horizontally. Extensions on the spaced apart legs of the cart include at least two elongate upright posts which are spaced apart sufficiently to receive a thin auto body part such as a hood panel or windshield. Elongate support arms may be attached to the upright members of the frame by inserting tabs of the arms into slots in the upright members. The shelf and basket members are supported on a pair of side brackets which have tabs which are received in slots in the upright members. The legs may be adjusted from a parallel position to one which has the legs diverging. The legs are supported by casters mounted at the ends of the legs and at the ends of the leg extensions. A small parts drawer may be carried in a drawer support which can be suspended from either a shelf or a basket member. S-hooks and elastic cords may be attached to cross bars separating the upright members, or from the elongate support arms or the side brackets of the shelf or basket members.

A walker device for assisting an individual with mobility which is temporarily convertible to a wheeled transportation chair, includes a frame structure having two front legs and two rear legs, each of the legs having a leg extension adjustably attached thereto and supported on a rotatable wheel. A seat is attached to the frame structure. A backrest is selectively disposed in a front position for a rearward seating condition or in a rear position for a forward seating condition. A footrest assembly is optionally attached to the frame structure and is adapted to pivot about first and second pivoting axes parallel to each other, between a folded position and an unfolded position optionally with different height levels.

The exercise devices disclosed herein are configurable to allow a user to perform various exercises. The exercise device can include an adjustable bench assembly connected with a frame supporting a cable-pulley assembly providing a user interface with a resistance system. A user can interface with an actuation component to pull resistance cables against resistance from the resistance system. Various exercise accessories can be provided that are easily connected with and removed from the exercise device to allow a user to perform different exercises. Some examples of exercise accessories are used to configure the exercise device for squat, abdominal, leg extension, leg curl, and arm curl exercises. The frame can also be configured to selectively place the exercise device in a stationary operating configuration supported by the frame on a support surface and a storage configuration wherein the exercise device is rollingly supported on the support surface by wheels.

An endoluminal graft includes a unitary tube of graft material forming two adjacent legs that are integral and monolithic to each other. The graft can be part of a prosthesis assembly for treatment of branched vascular systems and can function as an integral bifurcated leg extension prosthesis in combination with a main bifurcated prosthesis. In treating abdominal aortic aneurysms, the graft can be deployed within both iliac arteries.

An exercise device for stretching the legs of a user with pressure being applied mainly at the inner thighs, including a seat member and a horizontally disposed rail mounted at one end to the seat member and extends forwardly therefrom and terminates with a free end. Near the free end of the rail a reciprocating sleeve engages the rail for horizontal adjustment thereon. A leg supporting member is mounted pivotally at one end to the seat member on opposing sides of the rail and each such member has a free end. A linking arm is pivotally connected on opposite sides of the rail and at one end to the rail, and each such arm is connected at opposite end to the leg supporting member. A leg deck is mounted at about the side of each leg supporting member to retain the leg of the user in a horizontal position. An engagement member is mounted on each leg supporting member mediate the seat and the leg deck, and adaptable to engage the inside of the thigh of the user. Actuating cylinder is affixed to the sleeve to pivotally actuate the linking arms upon horizontal adjustment of the sleeve so as to impart an arcuate opening and closing movement to the leg supporting members, whereby pressure is applied on the inside of the user's thigh upon leg stretching movement.

A stent graft (2) for treatment of an emergency rupture of, for instance, the aorta adjacent the aortic bifurcation. The stent graft comprising a tubular body (8) with a bifurcation (10) in the tubular body defining a first long leg (12) and a second short leg (14). The second leg has a valve arrangement (18) to prevent fluid flow through the second leg from the stent graft. The valve can be opened from external of the stent graft for the placement of a leg extension stent graft (90) therethrough.
