  • Publication number: 20090036888
    Abstract: An ambulatory spinal unloading method and apparatus are implemented to achieve a desired minimum level of residual cushioning in response to a biasing force applied to the associated apparatus tensioning and/or compression mechanism(s). The ambulatory spinal unloading apparatus may further include a treatment system to provide desired levels of nerve and/or muscle stimulation in addition to hot and/or cold elements to provide further therapeutic effects as desired or necessary.

  • Publication number: 20090030359
    Abstract: A device and method for applying intermittent passive traction (IPT) that includes an initial phase followed by a sustained traction phase and finally a relaxation phase. During the first phase of IPT, the spinal elements are placed under gentle traction. This period of time reduces the normal forces across the vertebral bodies, facet joints, paraspinal musculature, etc. The second phase holds the spine in sustained traction, further reducing the forces across the spinal elements, encouraging natural healing to occur and allowing the muscles a period of relaxation. The third phase includes the gradual reduction of traction. During this final phase, the normal forces across the spine are reestablished as the IPT device slowly releases traction. The method resolves many of the most limiting problems associated with traction, CPM, and passive treatment modalities.

  • Publication number: 20030235481
    Abstract: A torque lock/indicator including first and second members and a compression ring for sealingly contacting a surface of the first member. The first member has first and second contact surfaces and structure for generally axially accommodating a connector. The second member has a ring member and a plurality of extensions extending from the ring member, each extension has an angled first contact surface and a second contact surface proximate the first contact surface. The connector is tightened until the compression ring is compressed to a predetermined degree. As the compression ring is being compressed the first member first contact surface is slidingly displaced against the second member contact surface. When the connector has been tightened to a predetermined level of torque, the first member first contact surface has been displaced past the second member first contact surface and the first member second contact surface strikes the second member second contact surface generating a mechanical vibration.

  • Publication number: 20020076296
    Abstract: A torque lock/indicator including an upper member, and lower member and a compression ring disposed between the upper and lower members. The upper member has at least one extension with an angled contact surface and a locking surface proximate the locking surface. The lower member has an angled, substantially peripheral contact surface and a locking surface proximate the contact surface. An optional cap is provided which is secured to the upper member or the lower member by being interlocked or cemented thereto.

  • Patent number: 6237602
    Abstract: An force generator includes an elongate force generator body that has a longitudinal dimension and has a fluid chamber defined therein. The force generator body exhibits a dimensional extension responsive to an increase in fluid in the fluid chamber and a dimensional retraction responsive to a decrease in fluid in the fluid chamber. A restraint apparatus channels the dimensional extension/retraction into the longitudinal dimension and restrains dimensional extension in a dimension transverse thereto.

  • Patent number: 5950628
    Abstract: An ambulatory, wearable support to be worn by a person for applying an extending force to a portion of the human anatomy while being worn, the portion of the human anatomy having an anterior portion and an opposed posterior portion, includes a first anchor member substantially encircling a first portion of the human anatomy, A second anchor member is spaced apart from the first anchor member, the portion of the human anatomy that is to be subjected to the extending force being disposed substantially between said first and second anchor members. A plurality of extender sets have at least one selectively inflatable bladder. The at least one bladder has a first end operably coupled to the first anchor member and a second end operably coupled to the second anchor member, the plurality of extender sets being spaced apart and disposed both anteriorly and posteriorly with respect to the portion of the human anatomy that is to be subjected to the extending force.
