Devices, systems, and methods employ an implant that is sized and configured to attach in, on, or near the annulus of a dysfunctional heart valve. In use, the implant extends either across the minor axis of the annulus, or across the major axis of the annulus, or both. The implant restores to the heart valve annulus and leaflets a more functional anatomic shape and tension. The more functional anatomic shape and tension are conducive to coaptation of the leaflets, which, in turn, reduces retrograde flow or regurgitation.

A multimode fiber including a core and a cladding. The core has a radius (R1) of 24-26 μm, the refractive index profile thereof is a parabola, and the maximum relative refractive index difference (Δ1) is 0.9-1.1%. The cladding surrounds the core and includes from inside to outside an inner cladding, a middle cladding, and an outer cladding; a radius (R2) of the inner cladding is 1.04-1.6 times that of the core, and a relative refractive index difference (Δ2) thereof is −0.01-0.01%; the middle cladding is a graded refractive index cladding whose radius (R3) is 1.06-1.8 times that of the core, and a relative refractive index difference thereof is decreased from Δ2 to Δ4; and a radius (R4) of the outer cladding is 2.38-2.63 times that of the core, and a relative refractive index difference (Δ4) thereof is between −0.20 and −0.40%. The invention reduces the additional bending loss of the fiber, improves the bending resistance and mechanical properties, basically eliminates the internal stress, and ensures the service life even working for a long term under the condition of low radius. The method for producing the fiber is simple, effective, and suitable for mass production.

A container for the dispensing of wire or cable has an external carton which receives a reel of cable supported by two caddies. Each caddy has an inwardly extending substantially cylindrical bushing which is received in a central hole of a respective cable reel flange. The cylindrical bushings are disposed on an axis which is a first distance from an upper surface of a bottom panel of the carton. The largest radius of the reel flanges is preselected to be smaller than this first distance such that the reel may freely rotate inside of the carton on the bushings. Cable is pulled through a slot in the carton's front panel. Left and right panels of the carton each have an arbor hole formed therein which may receive an axial rod, the rod also extending through the reel and caddies. The axial rod may be used to join two or more cartons together and may further serve as a support for attachment to a dolly, hand truck, or four-wheeled cart. In one embodiment, cable may be pulled through one or more pass-through slots formed in the tops and bottoms of stacked containers, such that cable from multiple containers is drawn through one slot on the top of the stack.

A first wrist element is rotatably provided on the front end of a forearm base of a robot. A second wrist element is rotatably provided on the first wrist element. A welding torch is rotatably supported via a transmission mechanism. A wire feeder is disposed at a position other than a forearm. A torch cable is fitted to a slider with an intermediate fitting section. A slider can be pulled backward by returning a wire connected to a tension generator using a pulley. In place of the fitting section, an intermediate guiding section can be provided.

The unit also includes a power take off cable connected to the linear generator and leading via the seabed to shore, and is characterized in that the buoyant structure is provided with fixed buoyancy and with elements to vary the surface of the buoyant structure that is exposed to the dynamic pressure of the wave, to optimize the surface for an efficient power take-off for more than one wave frequency and to control the tension in the taut mooring lines.

A brake disc for a disc brake having one or more sliding or not sliding discs on a hub or other central part is provided. The brake disc has an outer circumference and an inner circumference with a number of alternating teeth and gaps on the inner circumference. One or more measures are taken to reduce the risk of crack formation. One of the measures is to arrange areas of reduced material thickness at and / or adjacent each tooth. The areas of reduced material thickness may be openings having an axial or radial extent. Other measures include designing the teeth and gaps in an appropriate way and forming the brake disc with different properties at different parts.

A physical rehabilitation device for the treatment of a medical condition of the foot known as plantar fasciitis includes a splint which is connected to the toe and ankle of a patient. The splint can be used in a method for treating plantar fasciitis known as “dynamic splinting”. This device allows the patient to bend the ankle and thus dynamically change the flexion in the foot of the patient. The device itself is unique, but the method of treatment made possible by this device is also unique.

A method for spreading a hammock is disclosed. The method may include selecting a hammock comprising a hammock base having a first end, a second end opposite the first end in a longitudinal direction, a first side, and a second side opposite the first side in a lateral direction. The method may further include suspending the first end of the hammock base from a first anchor and suspending the second end of the hammock base from a second anchor. Once suspended, the hammock base may be spread in the lateral direction using exclusively a dynamic spreader system. The dynamic spreader system may automatically adjust the amount of the spreading in response to changes in the weight, shape, or orientation of contents within the hammock base.

According to some embodiments, a winch tightening apparatus comprises a mounting plate; a first moment arm coupled to the mounting plate and configured to provide leverage for rotating the mounting plate; and a pawl comprising a first end and a second end. The first end is pivotally coupled to the mounting plate such that the second end pivots to engage a ratchet gear when the mounting plate is rotated in a first direction and pivots to disengage the ratchet gear when the mounting plate is rotated in a second direction opposite the first direction. Some embodiments include a second moment arm coupled to the mounting plate and configured to provide leverage for rotating the mounting plate. Some embodiments include a counterweight coupled to the mounting plate and positioned to rotate the mounting plate in the second direction.

In a ratchet-type tensioner having a plunger with rack teeth formed thereon and a piston with ratchet teeth that engage the rack teeth, the ratchet teeth can be disengaged from the rack teeth by insertion of a tool through a tool insertion hole in the tensioner housing and exerting a prying action on the toothed end of the piston to move the piston away from the plunger. Alternatively if an oblique camming surface is formed on the toothed end of the piston, the ratchet teeth can be disengaged from the rack teeth by pushing the tool inward against the oblique camming surface. The piston and the hole in which it slides are shaped to prevent rotation of the piston. The ratchet teeth on the piston and the rack teeth on the plunger can be oblique to allow setback of the plunger when excessive force is exerted on the plunger.

A method of anchoring soft tissue to a suitable bone site, using a soft suture anchor, includes steps of disposing the soft suture anchor on a shaft of an inserter, and securing a proximal end of a tensioning suture limb, extending proximally from the soft suture anchor, to structure in a handle of the inserter, so that it is maintained in place at a first level of holding tension (Thold). The inserter shaft is inserted into a bone hole at a desired procedural site, so that the soft suture anchor is positioned at a location where it is to be anchored. A further step involves actuating a control mechanism in the inserter handle to move the structure proximally to apply a second level of deployment tension (Tload) to the tensioning suture limb.
