Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
109 words
A system for recovering bone particles from a fluid removed from a patient, comprising: a cutting instrument yielding the fluid; a housing having first and second fluid reservoirs therein; a flow inlet in fluid communication with the instrument and entering the first fluid reservoir; a flow outlet in fluid communication with the instrument and exiting the second fluid reservoir; a partition having a top and separating the first and second fluid reservoirs, wherein the partition is configured to allow the fluid to spill over the top from the first fluid reservoir to the second fluid reservoir; and a filter positioned between the second fluid reservoir and the flow outlet.
Claim 2
Independent Claim
109 words
A system for recovering bone particles from a fluid removed from a patient, comprising: a cutting instrument yielding the fluid; a housing having first and second fluid reservoirs therein; a flow inlet in fluid communication with the instrument and entering the first fluid reservoir; a flow outlet in fluid communication with the instrument and exiting the second fluid reservoir; a partition having a top and separating the first and second fluid reservoirs, wherein the partition is configured to allow the fluid to spill over the top from the first fluid reservoir to the second fluid reservoir; and a filter positioned between the second fluid reservoir and the flow outlet.
Claim 3
Independent Claim
101 words
A system for recovering bone particles removed from a patient, comprising: an instrument for yielding bone particles; a housing having first and second fluid reservoirs therein; a flow inlet in fluid communication with the instrument and entering the first fluid reservoir; a flow outlet in fluid communication with the instrument and exiting the second fluid reservoir; a partition having a top and separating the first and second fluid reservoirs; and a fluid containing bone particles filling the first reservoir wherein the partition is configured to allow the fluid to spill over the top of the partition and into the second reservoir.
Claim 4
Independent Claim
101 words
A system for recovering bone particles removed from a patient, comprising: an instrument for yielding bone particles; a housing having first and second fluid reservoirs therein; a flow inlet in fluid communication with the instrument and entering the first fluid reservoir; a flow outlet in fluid communication with the instrument and exiting the second fluid reservoir; a partition having a top and separating the first and second fluid reservoirs; and a fluid containing bone particles filling the first reservoir wherein the partition is configured to allow the fluid to spill over the top of the partition and into the second reservoir.
Claim 5
Dependent Claim
27 words
The system of claim 2 , wherein the fluid in the first reservoir has a higher concentration of bone particles than the fluid in the second reservoir.
Claim 6
Independent Claim
96 words
A method of recovering bone particles from a fluid slurry, comprising: filling a first fluid reservoir with the slurry such that fluid passes over a top of a partition and into a second fluid reservoir, whereby the bone particles collect in the first fluid reservoir such that the fluid which passes over the top of the partition and into the second fluid reservoir has a substantially reduced concentration of bone particles therein; and recovering the bone particles from the first fluid reservoir; and directing the fluid from the second fluid reservoir to irrigate an operative site.
Claim 7
Independent Claim
96 words
A method of recovering bone particles from a fluid slurry, comprising: filling a first fluid reservoir with the slurry such that fluid passes over a top of a partition and into a second fluid reservoir, whereby the bone particles collect in the first fluid reservoir such that the fluid which passes over the top of the partition and into the second fluid reservoir has a substantially reduced concentration of bone particles therein; and recovering the bone particles from the first fluid reservoir; and directing the fluid from the second fluid reservoir to irrigate an operative site.
Claim 8
Independent Claim
103 words
A system for recovering bone particles removed from a patient, comprising: a housing; a rotatable filter mounted within the housing, separating a first fluid reservoir disposed within an inner perimeter of the filter from a second fluid reservoir disposed around an outer perimeter of the filter; a flow inlet entering the first fluid reservoir; and a flow outlet exiting the second fluid reservoir, wherein rotation of the filter generates a centrifugal force which separates the bone particles from fluid passing through the filter from the first reservoir to the second reservoir, wherein the rotatable filter has outwardly slanted sides and a curved bottom.
Claim 9
Independent Claim
103 words
A system for recovering bone particles removed from a patient, comprising: a housing; a rotatable filter mounted within the housing, separating a first fluid reservoir disposed within an inner perimeter of the filter from a second fluid reservoir disposed around an outer perimeter of the filter; a flow inlet entering the first fluid reservoir; and a flow outlet exiting the second fluid reservoir, wherein rotation of the filter generates a centrifugal force which separates the bone particles from fluid passing through the filter from the first reservoir to the second reservoir, wherein the rotatable filter has outwardly slanted sides and a curved bottom.
Claim 10
Independent Claim
129 words
A system for recovering bone particles removed from a patient, comprising: a sub-system for removing particles of bone at an operative site on a bony structure; a sub-system for irrigating the operative site to yield a slurry comprising the bone particles; a sub-system for removing the slurry from the operative site; a sub-system for recovering the bone particles from the slurry, wherein the sub-system for removing the slurry from the operative site is in fluid communication with the a sub-system for recovering the bone particles from the slurry, such that the slurry is directed into the sub-system for recovering the bone particles from the slurry, wherein fluid outflow from the sub-system for recovering the bone particles from the slurry is directed to the sub-system for irrigating the operative site.
Claim 11
Independent Claim
129 words
A system for recovering bone particles removed from a patient, comprising: a sub-system for removing particles of bone at an operative site on a bony structure; a sub-system for irrigating the operative site to yield a slurry comprising the bone particles; a sub-system for removing the slurry from the operative site; a sub-system for recovering the bone particles from the slurry, wherein the sub-system for removing the slurry from the operative site is in fluid communication with the a sub-system for recovering the bone particles from the slurry, such that the slurry is directed into the sub-system for recovering the bone particles from the slurry, wherein fluid outflow from the sub-system for recovering the bone particles from the slurry is directed to the sub-system for irrigating the operative site.
Claim 12
Independent Claim
78 words
A method of recovering bone particles removed from a patient, comprising: generating particles of bone at an operative site on a bony structure; irrigating the operative site to yield a slurry comprising the bone particles; suctioning the slurry away from the operative site; and directing the slurry into a system for separating the bone particles from the slurry; and directing fluid outflow of the system for separating the bone particles from the slurry to irrigate the operative site.
Claim 13
Independent Claim
78 words
A method of recovering bone particles removed from a patient, comprising: generating particles of bone at an operative site on a bony structure; irrigating the operative site to yield a slurry comprising the bone particles; suctioning the slurry away from the operative site; and directing the slurry into a system for separating the bone particles from the slurry; and directing fluid outflow of the system for separating the bone particles from the slurry to irrigate the operative site.
