Abstract

Abstract A therapeutic device to mobilize the spinal joints and soft tissues surrounding the human spine. The device includes two substantially solid spherical balls mounted on a shaft for independent rotation. In one embodiment, the balls have a spherical to elliptical configuration and comprise an inner ball portion of a variable density synthetic plastic material and with an outer covering or portion comprised of a flexible material. The balls have a confronting area forming a substantially elliptical shape extending from a major spherical ball portion. Another embodiment comprises two spherical rubber balls having an inner ball formed of hard material to assist in the mobilizing operation and an outer flexible rubber cover. In either embodiment, the balls may be mounted on the shaft via suitable sleeves disposed through the inner ball portions. The device may be used in self-treatment or may be applied by another person.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 149 words
A self-usable device for mobilizing soft tissue, intervertebral joints, and facet joints of a human spine comprising a pair of substantially spherical independently rotatable rollers mounted on a shaft, the rollers being spaced apart by a fixed distance sufficient to straddle a human spine area and being sized to mobilize the soft tissue, intervertebral joints, and facet joints of the human spine, each roller having a core comprising closed cell microcellular polyethylene foam and a resilient cover comprising vinyl foam substantially covering the entire core, the rollers being able to smoothly form into a substantially elliptical shape for enabling mobilizing the soft tissue, intervertebral joints, and facet joints of a spine, and the shaft having two end portions extending beyond the rollers thereby forming a pair of handles for facilitating the user placing the device adjacent the spine area to mobilize the soft tissue, intervertebral joints, and facet joints.
Claim 2
Dependent Claim 149 words
A self-usable device for mobilizing soft tissue, intervertebral joints, and facet joints of a human spine comprising a pair of substantially spherical independently rotatable rollers mounted on a shaft, the rollers being spaced apart by a fixed distance sufficient to straddle a human spine area and being sized to mobilize the soft tissue, intervertebral joints, and facet joints of the human spine, each roller having a core comprising closed cell microcellular polyethylene foam and a resilient cover comprising vinyl foam substantially covering the entire core, the rollers being able to smoothly form into a substantially elliptical shape for enabling mobilizing the soft tissue, intervertebral joints, and facet joints of a spine, and the shaft having two end portions extending beyond the rollers thereby forming a pair of handles for facilitating the user placing the device adjacent the spine area to mobilize the soft tissue, intervertebral joints, and facet joints.
Claim 3
Dependent Claim 177 words
A self-usable device for mobilizing soft tissue, intervertebral joints, and facet joints of a human spine comprising a pair of substantially spherical independently rotatable rollers mounted on a shaft, the rollers being spaced apart by a fixed distance sufficient to straddle a human spine area and sized to mobilize the soft tissue, intervertebral joints, and facet joints of the human spine, each roller having a core and a resilient cover, the core comprising closed cell microcellular polyethylene foam for providing firmness and resistance for enabling forces to be applied to the transverse processes of the spine while clearing the midline spinous processes, the resilient cover comprising vinyl foam substantially covering the entire core so as to provide elastic contact surfaces and sufficient padding to enable the device to mobilize the soft tissue, intervertebral joints, and facet joints of the spine while preventing bruising and producing a spreading force, and the shaft having two end portions extending beyond the rollers thereby forming a pair of handles for facilitating the user placing the device adjacent the user's spine area.
Claim 4
Dependent Claim 177 words
A self-usable device for mobilizing soft tissue, intervertebral joints, and facet joints of a human spine comprising a pair of substantially spherical independently rotatable rollers mounted on a shaft, the rollers being spaced apart by a fixed distance sufficient to straddle a human spine area and sized to mobilize the soft tissue, intervertebral joints, and facet joints of the human spine, each roller having a core and a resilient cover, the core comprising closed cell microcellular polyethylene foam for providing firmness and resistance for enabling forces to be applied to the transverse processes of the spine while clearing the midline spinous processes, the resilient cover comprising vinyl foam substantially covering the entire core so as to provide elastic contact surfaces and sufficient padding to enable the device to mobilize the soft tissue, intervertebral joints, and facet joints of the spine while preventing bruising and producing a spreading force, and the shaft having two end portions extending beyond the rollers thereby forming a pair of handles for facilitating the user placing the device adjacent the user's spine area.
Claim 5
Dependent Claim 18 words
The device of claim 2 wherein the resilient cover is between one-sixteenth to one-fourth of an inch thick.
Claim 6
Dependent Claim 143 words
A spinal soft tissue and joint mobilizer comprising a pair of substantially spherical rollers independently and rotatably mounted on a shaft which ends in handles and having low friction confronting surfaces between the rollers and the shaft, between the rollers themselves, and between the rollers and the handles, each roller comprising a closed cell microcellular polyethylene foam inner core having density to provide resistance for mobilizing soft tissue, intervertebral joints, and facet joints and a vinyl foam resilient outer covering substantially covering the core and sufficiently flexible to enable mobilizing soft tissue, intervertebral joints, and facet joints, and spreading forces while preventing bruising, and each roller having an apex at a point furthest away from the shaft, a diameter of approximately three and one-half inches at the apex, and fixed spacing of approximately two to six inches apart as measured at said apexes.
Claim 7
Dependent Claim 143 words
A spinal soft tissue and joint mobilizer comprising a pair of substantially spherical rollers independently and rotatably mounted on a shaft which ends in handles and having low friction confronting surfaces between the rollers and the shaft, between the rollers themselves, and between the rollers and the handles, each roller comprising a closed cell microcellular polyethylene foam inner core having density to provide resistance for mobilizing soft tissue, intervertebral joints, and facet joints and a vinyl foam resilient outer covering substantially covering the core and sufficiently flexible to enable mobilizing soft tissue, intervertebral joints, and facet joints, and spreading forces while preventing bruising, and each roller having an apex at a point furthest away from the shaft, a diameter of approximately three and one-half inches at the apex, and fixed spacing of approximately two to six inches apart as measured at said apexes.
