A plurality of resilient plasticized members, each having circular cross sectional profiles, are provided and extend between the inner and outer shells in a three dimensional array in order to spatially support said outer shell a distance from an outer surface of said inner shell. The resilient members include any of disk or sphere shaped components, each having outer and inner flattened mounting locations securing to opposing locations of the inner and outer shells.

Abstract: A force attenuating helmet construction including a rigid layer generally conforming to the wearer's head. A plurality of force absorbing and reacting portions extend from locations of the rigid layer such that, in response to an impact event experienced by the helmet, the absorptive and reactive forces minimize impact forces transferred to the user's head and spine. The helmet can include inner and outer rigid layers, or shells, and which are spatially supported by a plurality of force attenuating components. A dual compression coil is associated with each of opposite end mounting portions of a face mask with the outer shell for providing for bi-directional force absorbing displacement of the mask portion.

Abstract: A joint implant assembly including a spherical shaped component adapted to securing to an end of a first joint defining bone and a recess shaped component adapted to securing to an end of a second joint defining bone. Each of the components establishes an opposing wear surface, at which microscopic sized particles build up over time resulting from prolonged use of the joint. At least one of the spherical and recess shaped components exhibits a plurality of interior entrapment chambers, each of which including a narrow-most entranceway location communicating with the wear surface. The entrapment chambers further exhibit outwardly widening capture profiles extending within the associated component for securing volumes of the microscopic particles away from a zone defined between the wear surfaces.

Abstract: A joint assembly incorporated into reconditioned end surfaces established between an upper bone and an opposing lower bone. The assembly includes a pair of first components anchored into reconditioned bone end surfaces of a first joint defining bone and exhibiting a flexible and band-shaped loop displace-ably supported along exposed undersides established between outer portions which are assembled around the bands. A second component anchored into a second reconditioned end surface of a second joint defining bone exhibits a planar support surface upon which said bands are in contact with and displace during articulating motion of the bones. Entrapment pockets are formed within the first components for collecting wear particles and debris resulting from displacement of the belt.

Abstract: An artificial hip joint assembly including a ball mounted atop a supporting stem, the stem adapted to being mounted to a reconditioned end of a femur bone, with the ball adapted to seat within an acetabulum socket of a pelvic bone. An intermediate component is mounted between the ball and stem, the intermediate component incorporating force absorbing and redirecting properties at an engagement interface between the ball and stem in response to impact forces generated upon the ball by the pelvic bone. The intermediate component can be constructed of a softer material than either the ball or stem, the intermediate component can further include a sleeve exhibiting a plurality of interior threads and facilitating mounting of an exteriorly threaded end location of the stem.

Abstract: An implant assembly for re-establishing a glenohumeral joint between a scapula and humerus. A first receiver is adapted to being mounted to a reconditioned glenoid cavity defined in the scapula, with a second receiver adapted to being mounted to a reconditioned humeral head associated with the humerus. A three dimensional and at least partially spherical shaped component is interposed between the first and second receivers for establishing each of a first articulating interface with the first receiver and a rotating interface with the second receiver.

Abstract: An implant assembly for re-establishing a glenohumeral joint between scapula and humerus bones. A ball has a first exposed convex support surface and a first reverse convex bone contacting surface extending from a first annular perimeter edge established with the first convex support surface. A first stem extends from the first reverse convex surface such that the first reverse convex surface and first stem are adapted to being mounted into a reconditioned glenoid cavity defined in the scapula. A receiver has a second exposed convex surface, a rim edge extending about a portion of said second exposed convex surface and defining a concave profile recessed within the second exposed convex surface and so that the concave profile seats a portion of the first exposed convex surface of the ball in an articulating relationship. The receiver further has a second reverse convex bone contacting surface extending from a second annular perimeter established with the second exposed convex surface.
