A device for occluding a hollow anatomical structure includes a clamp having at least first and second clamping portions adapted to be placed on opposite sides of the anatomical structure. At least one of the first and second clamping portions is movable toward the other from an open position to a clamping or closed position to occlude the anatomical structure. The clamp has an annular shape configured to surround the hollow anatomical structure in the open position and a flattened shape in the clamping position configured to occlude the hollow interior of the anatomical structure. The clamp is preferably covered with fabric to promote tissue ingrowth. A clamp delivery and actuation device is provided for allowing the clamp to be applied in either an open surgical procedure or a minimally invasive procedure.

A robotic surgical system incorporating a surgical robot attached to a patient's bone by an attachment member, such that motion of the bone induces corresponding motion of the robot, maintaining the robot/bone positional relationship. The robot is supported on a mechanical mounting member attached through a controlled joint to a bed-mounted base element. The controlled joint can alternatively enable the mechanical mounting member to move freely relative to the base element, or its position can be controlled by signal inputs adapted to prevent excessive force being applied in the system. Two modes of operation are available (i) free motion in which the control system is decoupled from the mounting member, which rides freely with patient bone motion, and (ii) servo-controlled motion, in which drive mechanisms control the joint motion to prevent application of excessive force on the patient bone or attachment member.

The instrumentation includes a spinal stabilizing longitudinal element (1) that is adapted to be placed in a generally parallel relationship with the portion of the spine (A) to be treated, a connector (6) having an opening (7) therethrough, a mechanism (10) is adapted to affix said bone-anchoring element (2) in the opening (7); the connector (6) has a hook portion (11) adapted to cooperate with a support (32) of the bone-anchoring element (2) for clamping the longitudinal element (1); the hook portion (11) has at its bottom side a recess (12) for receiving the longitudinal element (1); the longitudinal element (1) is clamped against said support (32), so that the force of the support (32) on the longitudinal element (1) is approximately parallel to the axis (D) of the bone-anchoring element (2).

A medical robotic system includes a surgical instrument, a robotic arm assembly, an input device, and a processor. The surgical instrument has an end effector and a sensor for sensing a force exerted by the end effector, and is operatively mounted on the robotic arm assembly. The processor is configured to receive commanded movement of the end effector from the input device, receive information of the force from the sensor, determine a reduced velocity of the commanded movement that would inhibit damage causing motion of the end effector, and control robotic manipulation of the surgical instrument in response to the commanded movement of the end effector while restricting the velocity of the commanded movement to the reduced velocity.

A body brace for a wearer has a combination of adjustment mechanisms and fasteners to help fit the body brace to a wearer. A wearer first fastens the body brace about his abdomen and lumbar regions to generally fit the body brace around the wearer's waist. The wearer then adjusts one set of adjustment mechanisms that adjust an upper and lower circumference of the brace to allow the brace to fit both straight and pear-shaped bodies. Lastly, the wearer adjusts a second set of adjustment mechanisms that tighten a rear panel of the body brace against a lumbar region of the wearer. Preferably, the adjustment mechanism that is used to tighten the rear panel is an advantaged adjustment mechanism to allow for fine-tuning and a snug fit.

A nasal dilator comprises a laminate of vertical layers each consisting of one or more members or components. The laminated layers form a unitary, or single body, truss featuring horizontal regions adapted to engage outer wall tissues of first and second nasal passages and to traverse the bridge of a nose therebetween. When in use the dilator acts to stabilize and/or expand the nasal outer wall tissues and prevent said tissues from drawing inward during breathing. The dilator includes means to direct its resilient properties comprising one or more interior or exterior material separations, or discontinuity of shape of material, formed in at least one region of the truss and extending through at least one layer of the dilator. Said material separation or discontinuity of shape may comprise an opening, relief cut, slit or notch, and which may be configured to separate or vertically protrude, in part, from the truss when the dilator is in use on the nose of a wearer. Said separation or vertical protrusion changes the angle of focused delaminating spring biasing forces generated by the resilient layer, transforming said forces, at least in part, from primarily peel forces into primarily shear forces, and further redistributing or imparting said transformed forces to tissue engaging surface areas extending outward and beyond said material separation.

A jaw movement mechanism for surgical tools has improved mechanical efficiency and other advantages. The jaw movement mechanism controls the orientation and position of a movable jaw relative to a fixed jaw through a range of movement of the movable jaw. The jaws maintain a parallel orientation throughout a portion of the range of movement of the movable jaw. The jaws maintain an angular relationship throughout a portion of the range of movement of the movable jaw.

A hydraulic suction fuse is mounted in a conventional debris collection trap of a swimming pool, spa or the like, to significantly reduce or eliminate any suction force on the bottom or side wall mounted drain of the swimming pool, spa or the like, as a result of the drain becoming essentially wholly covered by a body part of a person or other drain clogging article. Alternatively, the hydraulic suction fuse may be mounted in a compartment in line between the drain and a suction pump of a swimming pool, spa or the like. Thereby, a person captured by the suction force at the drain will be released and the person is free to move away from the drain essentially instantaneously upon contact with the drain. In one embodiment, the hydraulic suction fuse is self resetting once inflow through the drain is no longer restricted. In another embodiment of the hydraulic suction fuse, the hydraulic suction fuse may be easily manually reset.

A damping valve includes a valve seat member having a port and a first valve seat surrounding the port, a main valve body seated on or unseated from the first valve seat, the main valve body having a second valve seat oppositely to the valve seat member, a subsidiary valve body seated on or unseated from the second valve seat, a valve-body intermediate chamber provided between the main valve body and the subsidiary valve body in an inner circumferential side of the second valve seat, a restrictive passage that causes the port and the valve-body intermediate chamber to communicate with each other, the restrictive passage being configured to apply resistance to a flow of fluid passing therethrough, and a subsidiary valve body biasing means configured to bias the subsidiary valve body toward the main valve body.

A lower extremity orthosis is configured to be coupled to across at least one joint of a person for gait assistance and can incorporate knee, thigh, hip and ankle/foot assistive orthotic devices which can be used in various combinations to aid in the rehabilitation and restoration of muscular function in patients with impaired muscular function or control.

A shoe with elastic sole is disclosed. The shoe comprises an inner sole, an outer sole, an upper, and an elastic sole comprising a U-shaped cavity that has openings at the two lateral sides of the sole and a U-shaped spring pad made of carbon fiber plate provided in the cavity and between the inner sole and outer sole forming a highly elastic sole structure. A U-shaped spring tab is added to the core of the U-shaped portion of the U-shaped spring pad. Alternatively, the openings of the cavity at the two lateral sides of the sole can be closed, forming a totally enclosed cavity structure. Additionally, another U-shaped cavity with a U-shaped spring pad can be provided in the anterior portion of the sole, thus forming a sole structure with U-shaped spring pads both in the anterior and heel portion of the sole. A ventilation structure is provided between the inner sole and the outer sole. The vent structure comprises ventilation holes in the lateral and rear sides of the U-shaped cavity with check intake valves provided therein, and a ventilation hole in the front side of the U-shaped cavity with a check exhaust valve provided therein. The shoe has the advantages of large deformation and high elasticity during use that can provide comforts and forced ventilation with its simple structure that is suitable for manufacture by the footwear industry.

A cup carrier for holding beverage cups within a range of shapes and sizes is provided. The carrier has a cup-holding socket that has stabilizing shoulders and stabilizing walls extending inwardly and downwardly therefrom. The stabilizing walls include an upper portion having a relatively shallow angle and lower portions having a steeper angle. This extends the stabilizing wall further into an upper region of the socket, thereby enabling the stabilizing wall to contact smaller diameter cups at a higher point in order to increase stability. The upper portion contacts larger cups inserted into the socket. Because the upper portion initially has a relatively shallow angle, it exerts a desirable gripping force on the cups when it is deflected outwardly by the cup's sidewall. The carrier also includes a stepped center cavity for increased strength and rigidity.

A door closer with an electric motor-assisted closing feature, that may generate its own power to assist in closing, and controls the speed of opening and closing of the door during generation is disclosed. Embodiments of the present disclosure are realized by a motorized door closer that electrically creates a latch boost force for a closing door. The door closer includes a motor disposed to operatively connect to a door so that the door will moved toward closed when the motor moves, and a position sensor to determine a position of the door. A processor is programmed to exert a closing force on the door in the latch boost region or when it otherwise detects that a motor assist is needed.

Said elastic member comprises a hollow cylinder (5) of moulded plastic material arranged as a skirt, from the peripheral edge (4) towards said second end (1b) of the swivel pin (1), coaxially to it, said hollow cylinder (5) being provided with at least one opening (6) defining at least one helical strip (7) suitable to provide the hollow cylinder (5) with an elastic property.

A linear motor includes a magnet unit and a coil unit. The magnet unit includes two magnet arrays oppositely parallel and symmetrically located on a magnetic yoke: a first and a second magnet array. The coil unit is disposed in a magnetic gap between the two magnet arrays. In a spatial rectangular coordinate system defined by X, Y and Z axes, the coil unit includes a first and a second coil array arranged in a stacked manner in the Z-axis direction and staggered from each other by a distance of ΔP in the Y-axis direction. ΔP satisfies: when a control system charges the coil unit with a desired current, the coil unit generates a control force along the Y-axis direction, another control force along the Z-axis direction, and a moment about the X-axis direction, which may reduce a magnetic flux leakage and provide higher driving forces, making the linear motor generate required three degrees-of-freedom control force or control torque, and further improve vertical and horizontal magnetic fluxes in the magnet array.
