  • Patent number: 10219930
    Abstract: Systems and methods for tracking unintentional high amplitude muscle movements of a user and stabilizing a handheld tool are described. The method may include detecting motion of a housing of the handheld tool when manipulated by a user while the user is performing a task with a user-assistive device attached to an attachment arm of the handheld tool, and storing the detected motion in a memory of the handheld tool as motion data. Furthermore, the method may include controlling a first motion generating mechanism and a second motion generating mechanism by generating a first motion signal and a second motion signal that respectively drive the first motion generating mechanism in a first degree of freedom and the second motion generating mechanism in a second degree of freedom to stabilize motion of the user-assistive device attached to the attachment arm of the handheld tool.

  • Patent number: 9357985
    Abstract: A minimally invasive method for accessing a facet joint of the spine is provided. Embodiments of the method include creating a small incision directly over the facet joint and to allow direct access and visualization of the joint. A second incision, which may be a puncture wound, is provided at a distance from the first incision. A path between the second incision and the facet joint is then formed which may be curved or substantially straight. The path is preferably configured to intersect both facet surfaces. The path may be formed using an instrument which can be used to drill a hole across the facets, insert a fastener across the facets, or the like.

  • Patent number: 7416565
    Abstract: A transtibial patellar tendon bearing (PTB) prosthesis for below the knee amputees is disclosed. The prosthesis includes a socket, and a foot prosthesis attached to a modular shank component using a foot rotator device. Using the rotator device, the foot component of the prosthesis may be smoothly and axially rotated internally or externally ±150° with respect to the shank component about the axis of the shank component. The wide range of axial rotation enables a more even load distribution on the whole lower limb of an amputee and enables an amputee to comfortably assume a wide range of biomechanical positions, such as sitting or kneeling. A recoil spring, having a selectable tension, is positioned within the rotatable component and selectively limits and retains the relative rotation of the upper portion and the lower portions. A locking mechanism selectively prevents rotation when the foot component is engaged.

  • Patent number: 7367991
    Abstract: An annuloplasty ring having a three-dimensional discontinuous form generally arranged about an axis with two free ends that are axially offset. The ring is particularly suited for repair of the tricuspid valve, and more closely conforms to the annulus shape. The ring is more flexible in bending about radially extending axes than about the central axis. The ring may have an inner structural support covered by a pliable sleeve and/or a fabric tube. The structural support may have a varying cross-section, such as a C-shaped cross-section in a mid-section between two free ends and a rectangular cross-section at the free ends. A deliver template having a mounting ring with about the same shape as the ring facilitates implant, and may be releasably attached to a delivery handle. The deliver template may include a plurality of cutting guides for releasably attaching the annuloplasty ring thereto while presenting maximum outer surface area of the ring.

  • Patent number: 7361197
    Abstract: An anthropomorphic artificial hand having a mechanical system that allows for the digits to be compliant to pressure that tends to flex the digits, and provides for the digits to be self biasing to conform to the shape of the object being grasped. The hand comprises one to four fingers, with the fingers having up to three joints each. The hand may also comprise a thumb that can be rotated into and out of opposition of the fingers. The joints of the thumb are also self biasing to allow conformance to the object being grasped. The hand is of the voluntary closing operation, with all digits being self extending. This allows the hand to use two cables to operate if body powered (one for the fingers, one for the thumb). The hand may also be electronically powered using two channels for operating the fingers and thumb simultaneously.

  • Patent number: 7361196
    Abstract: A posterior vertebral stabilizer has a resilient member such as a linear spring, which operates in tension and compression. The resilient member may be kept straight by a stabilization rod extending through the spring, or by a telescoping assembly that encases the resilient member. The ends of the stabilizer are attachable to pedicles of adjacent vertebrae so that the stabilizer adds stiffness to control flexion and extension of the vertebrae. Two such stabilizers may be used, and may be connected together by a crosslink designed to limit relative rotation of the stabilizers. Thus, the stabilizers may restrict axial rotation and lateral bending between the vertebrae, while permitting stiffened flexion and extension. Such stabilizers help provide the stiffness of a healthy intervertebral disc. In the event that fusion of the joint becomes necessary, a set screw or other component may be used to further restrict flexion and extension.

  • Patent number: 7357818
    Abstract: A stent is designed to be placed in a lumen of a patient and extend therethrough. The stent includes a distal end and a proximal end. The distal end includes a distal retention structure and the proximal end includes a plurality of radially extending flexible segments to prevent migration of the stent through the lumen. At least one radially extending flexible segment at the proximal end is able to assume an outwardly everted configuration. The stent of the invention, due to its dimensions, shape, and rigidity, minimizes the force of contact and abrasion to sensitive areas of the patient's body, such as the trigone region of the bladder and the ureteral-vesical junction.
