Interengaging surgical staples (11, 31, 51, 71) are provided that are useful in systems for the surgical correction of defects in cardiac valves and/or supporting weaknesses in abdominal regions. The staples are constructed with at least one ring (21, 41, 61, 81) extending laterally from the upper end of one staple leg (15, 35, 55, 75), which once implanted provides for interengagement with the next staple by passage of the other leg (13, 33, 53, 73) of it therethrough. Either shape-memory staple design or an implantation tool causes the two staple legs to curve respectively toward each other once having penetrated the tissue, thus gathering and constricting the tissue in a region below the surface thereof. Elastic sections (67, 83) may be provided in the crown connectors to allow flex in the plane thereof.

A pedicle screw for use in the treatment of a spinal deformity includes a head assembly and a fastener portion extending from the head assembly. The pedicle screw includes a head assembly and a fastener portion that extends from the head assembly. The fastener portion extends from the head assembly and is adapted to be secured to a vertebra of a spinal column. The head assembly includes a stationary member and a movable member. The movable member is supported on the stationary member for movement (such as pivoting movement) relative thereto between an opened position and a closed position. When the movable member is in the opened position, the head assembly is adapted to receive a longitudinal member therein for treatment of a spinal deformity. Thereafter, the movable member can be moved to the closed position to properly align the pedicle screw with the longitudinal member. A locking member and a retention member can then be used to maintain the movable member in the closed position.

Surgical correction of presbyopia and hyperopia by a circularly distributed assembly of mini-bridges implanted between the interior surfaces of the ciliary muscle and the exterior surface of the lens capsule, for augmenting the transmission of the contraction force of the ciliary muscle/zonule assembly to the lens capsule. The lens is symmetrically squeezed by mini-bridges acting in concert with the ciliary muscle thus changing the curvature of the lens. The mini-bridges are composite synthetic muscles comprising either passive biocompatible mini-bridges made with polymeric gels, silicone polymers or a composite, electromagnetically or mechanically deployable mini-bridges, inflatable balloons or synthetic muscles. The surgical procedure comprises using a ciliary muscle relaxant to stretch the lens/zonules/ciliary muscle assembly. An ultrasonic biomicroscope (UBM) is then used to enable the surgeon to see the area for implantation and the mini-bridges and thus perform endoscopic or incisional surgery to implant the mini-bridges in and around zonular cavities.

A device for producing control data for a laser device for the surgical correction of defective vision. The device produces the control data such that the laser emits the laser radiation such that a volume in the cornea is isolated. The device calculates a radius of curvature R_CV* to determine the control data, the cornea reduced by the volume having the radius of curvature R_CV* and the radius of curvature being site-specific and satisfying the following equation: R_CV*(r,φ)=1/((1/R_CV(r,φ))+B_COR(r,φ)/(n_c−1))+F, wherein R_CV(r,φ) is the local radius of curvature of the cornea before the volume is removed, n_c is the refractive index of the material of the cornea, F is a coefficient, and B_COR(r,φ) is the local change in refractive force required for the desired correction of defective vision in a plane lying in the vertex of the cornea, and at least two radii r1 and r2 satisfy the equation B_COR(r=r1,φ)≠B_COR(r=r2,φ).

The invention is an apparatus (10) for treating inverted nipples and/or the collection of NAF. The invention includes an assembly which creates an airtight seal upon attachment to at least an areola (16) of an inverted nipple (18) and by rotation of a part thereof draws a partial vacuum to apply an outward force to the nipple; and a syringe (26) including a curved longitudinal axis (28), the syringe being carried by the assembly and being in fluid communication with a chamber (24) of the assembly upon attachment of the assembly to at least an areola of an inverted nipple, the syringe including a plunger (30) which is sealed against an inner surface (34) of the syringe and is rotatable to move along the longitudinal axis relative to the chamber which moves the plunger within a syringe body to expel air from the syringe body away from the chamber upon rotation of the plunger in a first direction and to aspirate air from the chamber upon attachment of the apparatus to the breast surrounding the nipple upon rotation in a second direction opposite to the first direction to create a partial vacuum within the chamber to evert the nipple.

The invention provides a device and a method for exercising a user's leg whose lower leg tibial portion can be rotatably controlled during exercise. The device includes user-controlled rotatable drums connected to a sheet that surrounds a lower leg cuff for rotating and providing corrective forces on a user's knee joint during leg exercise. The device can be used with weight training equipment commonly found in commercial gyms, as well as in a user's home, or in clinics, to assist in rehabilitating malaligned knee joints.

The invention relates to a device for measuring imaging errors in the human eye, wherein substantial scanning of the lens of the eye with a light beam or laser diode determines the measuring accuracy of local refractive power. Measuring accuracy of locally dependent refractive power is achieved by a two-dimensionally refractable tilting mirror which is embodied in the form of a microscanner mirror with the aid of a piezomotor for positioning and by electrically controllable liquid lenses. As a result, it is possible to manufacture the measuring device as small as possible, enabling it to be integrated in to a processing laser in order to monitor the result of treatment with a laser during individual adaptation of contact lenses, intraocular lenses or surgical correction of the retina in situ and to calculate data of a required correction.

A treatment device for the surgical correction of defective vision in an eye. The device includes a laser apparatus controlled by a controller. The controller determines a desired correction of defective vision from measurement data of the eye to produce control data for the laser, and to control the laser to emit radiation according to the control data, such that a lenticule-shaped volume is isolated in the cornea. The controller computes a lenticule-shaped intended volume, the removal of which from the cornea leads to an actual correction of defective vision in an optical zone in the eye which differs from the desired correction more at the edge of the optical zone than at the center of the optical zone. The thickness of the lenticule-shaped intended volume is less than the thickness of a lenticule-shaped comparison volume, the removal of which would bring about the desired correction of defective vision.

The invention discloses a cornea ablation method for customized vision correction. According to the invention, the shape of the front surface of a cornea is constructed through a backlight tracing manner, and the data of the cornea front surface before and after the design can be converted into the depth for the customized cornea ablation. By employing the method, the cornea ablation contour in eye refractive surgery can be more accurate, and better surgical correction effects can be achieved.
