  • Patent number: 6827744
    Abstract: A dynamic prosthetic foot having multiple load points includes a sole and an upper member that overlies the sole. A heel end of the upper member has a gradual ninety degree bend formed in so that it is normal to the sole. A longitudinally-extending slot divides the heel end of the upper member into a lateral pylon support and a medial pylon support. The lateral pylon support is thicker than the medial pylon support so that forces applied to the lateral and medial pylons are transferred to a greater extent to the medial pylon support. Vertical bounce during heel strike is eliminated, as is the flat spot. The foot further provides medial lateral stiffness, medial lateral stability, torsional flex and anysotropic stiffness. In a second embodiment, an elongate lateral and medial pylon replace the lateral and medial pylon supports, respectively.

  • Patent number: 6797009
    Abstract: A dynamic prosthetic foot has a heel of elasticity made of a lateral heel and a medial heel that are formed separately from one another. A lateral ankle diverges upwardly from a sole along a transverse parting line and includes a horizontal and a vertical part that collectively form a lateral ankle part. The horizontal part is supported by a return bend formed in the lateral heel. The medial heel includes a return bend formed integrally with the sole but includes no medial ankle upper part. Each of the two heel parts independently absorbs impacts generated during ambulation and therefore provides differentiated heel elasticity. The lateral heel transfers loads to the medial heel because the lateral ankle upper part is supported by the lateral heel and the return bend that forms the medial heel is unsupported.

  • Patent number: 6793683
    Abstract: A dynamic prosthetic foot provides medial and lateral stabilization. An ankle part diverges upwardly from a sole along a transverse parting line and includes a vertical part. A longitudinally extending slot divides the ankle part into a lateral and a medial ankle part and a pylon is connected to each of those parts. A plurality of parallel, equidistantly spaced, longitudinally extending slots are formed in the toe section and the heel section of the sole, respectively, to create a plurality of substantially independent toe and heel sections of narrow width. This enables the substantially independent toe and heel sections to respond independently to uneven terrain so that the user of the prosthetic foot is less likely to fall when ambulating over uneven terrain.

  • Patent number: 6793668
    Abstract: A balloon angioplasty or stenting apparatus includes a guide wire, a balloon catheter ensleeving the guide wire, and a guide catheter ensleeving the balloon catheter. The balloon catheter has slots formed in it to define elongate members between the slots. A joint is formed at the proximal, distal, and mid-point of each elongate member. Displacing the proximal and distal joints toward and away from one another causes the respective middle joints to displace radially outwardly and inwardly, respectively. A mesh that captures emboli while allowing blood perfusion partially overlies the jointed members is opened and closed when the jointed members are opened and closed. A guide wire having an outer coil and an inner rod slideably received within it has jointed members formed in the outer coil. The mesh is opened and closed by axially retracting and advancing the inner rod with respect to the outer coil, respectively.

  • Patent number: 6764631
    Abstract: A custom-fitting prosthetics liner is made without mixing silicone and without making a mold. A thermoformable liner is made by preparing a negative cast from a patient's residual limb, preparing a positive cast from the negative cast, and placing a thermoformable tubular liner over the positive cast. The positive cast and liner are heated in an oven for a predetermined time and temperature. Having acquired a new geometry, the cast and liner are removed from the oven and allowed to cool to room temperature. The liner is then removed from the cast. Alternatively the liner is heated, placed over the positive cast, cooled and removed. The interior surface of the liner conforms to the shape of the cast. The liner is elastic so that it returns to its new geometry when stretched and released. It therefore holds on to a residual limb even when the residual limb shrinks.

  • Patent number: 6765122
    Abstract: A hydrophilic dressing device for use with a gastrostomy tube. The device has a disc-shaped configuration with a central opening. A radial cut extends from the central opening to a peripheral edge of the device to create a pair of opposed free ends that are releasably attachable to one another to facilitate attachment of the device around the tube. The device is positioned in overlying relation to the patient's skin to absorb leaking bodily fluids and prevent skin irritation. The core of the device is a hydrophilic material such as hydrophilic polyurethane foam. The core is covered by nylon because the open mesh structure of nylon allows the fluids to be absorbed by the core material and because nylon does not stick to the patient's skin. The device is washable in a residential washing machine and can be re-used indefinitely.

  • Patent number: 6740172
    Abstract: A modular conveyor belt passes over and around at least one sprocket carried on a non-rotating hollow shaft and causes rotation of the sprocket. The sprocket includes a first pair of diametrically opposed sectors and a second pair of diametrically opposed sectors that are laterally staggered in relation to the first pair of sectors. Each sprocket is flanked by a pair of nozzles, each of which produces a fan-shaped spray. The fan-shaped sprays overlap one another across the lateral extent of the belt so that the entire breadth of the belt is cleaned. Adjacent fan-shaped sprays are angled relative to one another so that their respective sprays do not interfere with one another. The staggered sector design ensures that all sections of the belt are exposed to the spray. The nozzles are positioned to clean hinges of the belt when the hinges are open.

  • Patent number: 6740124
    Abstract: An endoprosthesis for below knee amputations includes a socket, a foam-covered pylon, and a prosthetic foot. A prosthetic knee is added for above knee amputations. A plastic sleeve is formed, heated, and stretched until it has a size sufficient to ensleeve the endoprothesis. The plastic sleeve is maintained at that enlarged size and cooled so that the resulting sleeve is substantially inelastic and is adapted to receive the endoprosthesis. The plastic sleeve is heated in areas where it does not conform exactly to the endoprosthesis until it shrinks and conforms exactly to the endoprosthesis, including the contour of the foam-covered pylon. The plastic sleeve then reveals all of the structural details of the prosthetic foam but does not apply compressive force to the foam. Lines of demarcation therefore do not form at the locations where the foam meets the prosthetic socket, the prosthetic knee, or the prosthetic foot.
