[ [ [ [0 0 0 00 0 0 04 4 4 4] ] ] ] Generally speaking, operations, such as spinal fusions, require the use of autologous,
cancellous bone. The use of this bone is generally preferred; however, the collection methods
currently available can be arduous and messy, and some are quite complicated. Indeed, some
conventional collection techniques even require the user to pour the contents of blood and bone onto
an absorbable pad, such as those sold under the “Telfa” trademark.
[ [ [ [0 0 0 00 0 0 05 5 5 5] ] ] ] In view of known apparatus and methods for collecting bone material, it is believed that one or
more needs exist for improvement in apparatus, kit and methods related to collecting bone material

DETAILED DESCRIPTION
[ [ [ [0 0 0 07 7 7 76 6 6 6] ] ] ] As a preliminary matter, it will readily be understood by one having ordinary skill in the
relevant art (“Ordinary Artisan”) that the present disclosure has broad utility and application. As
6/17
should be understood, any embodiment may incorporate only one or a plurality of the above-disclosed
aspects of the disclosure and may further incorporate only one or a plurality of the above-disclosed
features. Furthermore, any embodiment discussed and identified as being “preferred” is considered to
be part of a best mode contemplated for carrying out the present disclosure. Other embodiments also
may be discussed for additional illustrative purposes in providing a full and enabling disclosure of the
present disclosure. As should be understood, any embodiment may incorporate only one or a plurality
of the above-disclosed aspects of the disclosure and may further incorporate only one or a plurality of
the above-disclosed features. Moreover, many embodiments, such as adaptations, variations,
modifications, and equivalent arrangements, will be implicitly disclosed by the embodiments
described herein and fall within the scope of the present disclosure.
[ [0 07 77 7] ] Accordingly, while the present disclosure is described herein in detail in relation to one or
[ [0 07 77 7] ]
more embodiments, it is to be understood that this disclosure is illustrative and exemplary of the
present disclosure, and is made merely for the purposes of providing a full and enabling disclosure of
the present disclosure. The detailed disclosure herein of one or more embodiments is not intended, nor
is to be construed, to limit the scope of patent protection afforded the present disclosure, which scope
is to be defined by the claims and the equivalents thereof. It is not intended that the scope of patent
protection afforded the present disclosure be defined by reading into any claim a limitation found
herein that does not explicitly appear in the claim itself.
[ [ [ [0 0 0 07 7 7 78 8 8 8] ] ] ] Thus, for example, any sequence(s) and/or temporal order of steps of various processes or
methods that are described herein are illustrative and not restrictive. Accordingly, it should be
understood that, although steps of various processes or methods may be shown and described as being
in a sequence or temporal order, the steps of any such processes or methods are not limited to being
carried out in any particular sequence or order, absent an indication otherwise. Indeed, the steps in
such processes or methods generally may be carried out in various different sequences and orders
while still falling within the scope of the present disclosure. Accordingly, it is intended that the scope
of patent protection afforded the present disclosure is to be defined by the appended claims rather than
the description set forth herein.
[ [ [ [0 0 0 07 7 7 79 9 9 9] ] ] ] Additionally, it is important to note that each term used herein refers to that which the
Ordinary Artisan would understand such term to mean based on the contextual use of such term
herein. To the extent that the meaning of a term used herein—as understood by the Ordinary Artisan
based on the contextual use of such term—differs in any way from any particular dictionary definition
of such term, it is intended that the meaning of the term as understood by the Ordinary Artisan should
prevail.
[ [ [ [0 0 0 08 8 8 80 0 0 0] ] ] ] Regarding applicability of 35 U.S.C. §112, ¶6, no claim element is intended to be read in
accordance with this statutory provision unless the explicit phrase “means for” or “step for” is actually
used in such claim element, whereupon this statutory provision is intended to apply in the
interpretation of such claim element.
7/17
[ [ [ [0 0 0 08 8 8 81 1 1 1] ] ] ] Furthermore, it is important to note that, as used herein, “a” and “an” each generally denotes
“at least one,” but does not exclude a plurality unless the contextual use dictates otherwise. Thus,
reference to “a picnic basket having an apple” describes “a picnic basket having at least one apple” as
well as “a picnic basket having apples.” In contrast, reference to “a picnic basket having a single
apple” describes “a picnic basket having only one apple.”
[ [ [ [0 0 0 08 8 8 82 2 2 2] ] ] ] When used herein to join a list of items, “or” denotes “at least one of the items,” but does not
exclude a plurality of items of the list. Thus, reference to “a picnic basket having cheese or crackers”
describes “a picnic basket having cheese without crackers”, “a picnic basket having crackers without
cheese”, and “a picnic basket having both cheese and crackers.” Finally, when used herein to join a
list of items, “and” denotes “all of the items of the list.” Thus, reference to “a picnic basket having
cheese and crackers” describes “a picnic basket having cheese, wherein the picnic basket further has
crackers,” as well as describes “a picnic basket having crackers, wherein the picnic basket further has
cheese.”
[ [ [ [0 0 0 08 8 8 83 3 3 3] ] ] ] Referring now to the drawings, one or more embodiments of the present disclosure are next
described. The following description of one or more embodiments is merely exemplary in nature and
is in no way intended to limit the disclosure, its implementations, or uses.
Components of a Bone Collection Assembly of an Embodiment of the Disclosure
[ [ [ [0 0 0 08 8 8 84 4 4 4] ] ] ] An exemplary bone collection assembly in accordance with an embodiment of the present
disclosure comprises a collection trap and two interchangeable covers, each of which are configured
to attach to the collection trap in covering relation thereto.
[ [ [ [0 0 0 08 8 8 85 5 5 5] ] ] ] With reference to and an exemplary assembly 100 is shown. The
assembly 100 includes a collection trap comprises a liquid container 302 having a single, open end
comprising a mouth 304 of the container 302; a first cover comprising a first lid 102; and a second
cover comprising a second lid 202. The liquid container 302 is illustrated as being a 50 cc container
and is suitable for use; however, an 80cc container is currently preferred with graduations up to 60 cc.
[ [ [ [0 0 0 08 8 8 86 6 6 6] ] ] ] The container 302 includes integral bottom wall and sidewalls that define a continuous,
uninterrupted smooth surface, and preferable is cylindrical in shape. The sidewall also is preferably
transparent or translucent so that the contents of the container 302 can be viewed, especially as the
container 302 fills. A rim 306 surrounding the mouth 304 of the container 302 includes threads 308
for mating engagement with respective threads 108,208 of each of the lids 102,202. In this respect,
each lid 102,202 may be interchangeably screwed on top of the container 302 for watertight sealing of
the container 302 at the threads, as schematically indicated by the arrows 101,201 in An
illustration of the first lid 102 attached to the container 302 for trapping blood products and bone is
shown in ; and an illustration of the second lid 202 attached to the container 302 for separating
blood products and bone is shown in .
8/17
[ [ [ [0 0 0 08 8 8 87 7 7 7] ] ] ] With primary reference to the first lid 102 includes a suction port 104 and an intake
port 106. The suction port 104 is configured to receive a tube for application of suction to an interior
chamber 310 of the container 302 for holding liquid. The intake port 106 is configured to receive a
six-inch tube 110 by which a Frazier suction instrument (not shown) is attachable to the first lid 102.
The suction applied to the container 302 via the suction port 104 results in suction being applied via
the second port 106 to the Frazier suction instrument, whereby blood products and bone suctioned
using the Frazier suction instrument flow through the second port 106 into the collection chamber
310. Moreover, it will be understood that other suction instruments may be used and that the Frazier
suction instrument described is merely for purposes of illustration.
[ [0 08 88 8] ] Due to the orientation of the container 302 and, in particular, the location of the ports 104,106
[ [0 08 88 8] ]
in the lid 102 of the container 302, the blood products and bone that are suctioned with the suction
instrument are generally trapped and collected within the container 302 by gravity when the container
302 is maintained in a generally upright position with the lid 102 attached to the chamber 310.
[ [ [ [0 0 0 08 8 8 89 9 9 9] ] ] ] With primary reference to the second lid 202 includes a suction port 204, a vent 206,
and a plunger 210. The suction port 204 is similar to that of the first lid 102, and is configured to
receive a tube for application of suction to the interior chamber 310 of the container 302 when
attached thereto. The vent 206 is configured to permit air to enter into the chamber 310 of the
container 302 when attached thereto as a result of the application of the suction via the suction port
204, thereby resulting in an airflow. This airflow is utilized to transport blood products from the
chamber 310, as will be described in further detail below.
[ [ [ [0 0 0 09 9 9 90 0 0 0] ] ] ] The plunger 210 itself comprises a handle 212, a shaft 214, and a press head 216. The plunger
210 is able to transition (i.e., is transitionable) between a first, extended position (as shown in ), in which the press head 216 is located proximate a bottom 203 of the second lid 202, and a
second depressed position (as shown in ) in which the handle 212 is located proximate a top
205 of the second lid 202 and the press head 216 is located proximate the bottom 303 of the container
302 when the second lid 202 is attached to the container 302. First and second intermediate positions
of the plunger 210 between these first and second positions are shown, respectively, in and
.
[ [ [ [0 0 0 09 9 9 91 1 1 1] ] ] ] Furthermore, as shown in , the press head 216 includes a screen comprising two screen
portions 218,220. Each screen portion 218,220 preferably comprises a fine metal screen mesh. The
screen is configured to filter bone from the blood products, in that the screen includes openings
dimensioned to allow blood products to pass there through, but to generally block autologous,
cancellous bone obtained during a surgical procedure from passing therethrough. Consequently, when
the second lid 202 is attached to a container 302 that has filled with blood products and bone obtained
during a surgical procedure, transitioning of the plunger 210 from the first position to the second
position results in the separation of the blood products and the autologous, cancellous bone. The press
head 216 also includes a rubber O-ring 222 for sealing engagement with the interior sides of the
9/17
chamber 310 of the container 302 so that bone does not pass around the press head 216 during
transitioning of the plunger 210. The press head 216 attaches to the shaft 214 at 224.
[ [ [ [0 0 0 09 9 9 92 2 2 2] ] ] ] The bone collection assembly also includes a collection cup, an exemplary embodiment 410 of
which is shown in and a bone scoop, an exemplary embodiment 510 of which is shown in
The bone scoop 510 is used to physically transfer filtered bone retained in the collection trap
to the collection cup 410. The collection cup 410 is used to hold the autologous, cancellous bone until
needed in a surgical procedure.
[ [0 09 93 3] ] The foregoing called-out components of the bone collection assembly 100 preferably are made
[ [0 09 93 3] ]
out of one or more plastic materials, and may be manufactured using injection-molding processes.
Exceptions include the screen of the press head, which preferably is made out of a stainless steel
woven mesh; the tube, which preferably is made out of silicone; and the O-ring, which preferably is
made out of a rubber material.
An Exemplary Commercial Kit
[ [0 09 94 4] ] Components of an exemplary commercial kit 600 in accordance with the present disclosure
[ [0 09 94 4] ]
are shown in and comprises a container 302; a first lid 102; a tube 110; a second lid 202; and a
box 602. The kit 600 may also contain a collection cup 410 and a bone scoop 510. The container and
collection cup preferably are clear plastic, and the colors of the lids are white. The tube 110 preferably
comprises clear, plastic tubing. The tube 110 is attachable to the port 106 of the first lid 102 and may
either be separately contained within the box 602 or pre-attached to the second port 106. The bone
scoop 510 also preferably is white. The components in the box 602 are preferably packaged in sterile
pouches, are opened by sterile technique, and are intended to be placed on a sterile table within an
operating environment, such as a mayo table, and opened for use in preparation for, or during, a
surgical procedure. Furthermore, while a kit may include only one container within the scope of the
disclosure, the kit may include a second container (not shown) that is identical to the first container
whereby bone and blood can be captured during the surgical operation using the first lid and one of
the two containers even as bone is being filtered from blood using the second lid and the other
container. In a preferred commercial kit, a bone collection assembly represented by FIGS. 15-34 is
provided with two identical containers for use, as described below.
Exemplary Use During Surgical Procedure
[ [ [ [0 0 0 09 9 9 95 5 5 5] ] ] ] Once the need arises for collection of bone, a bone collection assembly kit is brought to the
surgeon and/or assistant. The box is opened, and a first lid is attached in threading engagement with
the container. The suction port of the first lid is then attached to a suction source. A Frazier suction
instrument (or other suction instrument) is attached to the open end of the plastic tubing attached to
the second port. Both the suction instrument and the suction source are conventionally provided in
individual operating rooms and are not part of the kit. Once the blood products and bone
/17
approximately fills the container, the suction is removed from the suction port. The first lid is then
removed from the container by unscrewing it while keeping the suction instrument attached on the
end of the tubing. Leaving the suction instrument attached will facilitate the process of further bone
collecting. Accordingly, the lid is placed on the surgical table for quick access later, or if a second
container is provided, then the lid is attached to the second container and the suction is reapplied to
the suction port for continued bone and blood collection.
[ [ [ [0 0 0 09 9 9 96 6 6 6] ] ] ] The steps of collecting bone and blood products within the container are illustrated in FIGS.
7a-7c.
[ [0 09 97 7] ] The second lid then is attached in threading engagement to the filled container. Suction is
[ [0 09 97 7] ]
applied to the suction port on the second lid while keeping the container upright not allowing for any
incidental suction of bone products. The user then depresses the plunger until it is fully depressed,
thereby compressing the bone and separating the bone from the blood products. The blood then is
suctioned away by tilting the container while the bone is maintained under pressure by depression of
the plunger. After the blood has been evacuated by the suction, the suction is removed and the plunger
is raised and locked—or otherwise maintained—in position. The lid is then removed from the
container. The bone within the container is then collected by use of the bone scoop and transferred to
the collection cup. Additionally, bone may adhere to the press head. Any bone adhering to the press
head also is collected with the bone scoop and transferred to the collection cup. Thereafter, if further
bone collecting is desired and a second container is not being used, then the first lid is again
reattached to the container and the foregoing steps are repeated for collecting bone and blood.
[ [ [ [0 0 0 09 9 9 98 8 8 8] ] ] ] The separation of bone and blood products within the container are illustrated in FIGS. 8a-8d,
and the transfer of the bone from the container to the collection cup is represented by FIGS. 9-10.
[ [ [ [0 0 0 09 9 9 99 9 9 9] ] ] ] Upon completion of the surgical procedure, or if the surgeon is in no further need for bone
collection, the bone collection assembly can be discarded by hazmat standards per facility given its
disposable design. Indeed, the bone collection assembly preferably is disposable, although in other
embodiments it is contemplated that one or more components of the bone collection assembly could
be reusable, preferably after autoclaving.
Additional Detail with Regard to the First and Second Lids
[ [ [ [0 0 0 01 1 1 10 0 0 00 0 0 0] ] ] ] With respect to additional details regarding the first lid 102 and second lid 202,
schematically illustrates, in part, a plan view of the underside of the first lid with a Frazier suction tip
instrument attached to the tubing; schematically illustrates, in part, a plan view of the
underside of the second lid without the press head, and reveals two 4mm stainless steel screws with
wide heads that collectively retain a 3mm rubber gasket in place; schematically illustrates, in
part, a plan view of the underside of the second lid without the press head, without the 3mm rubber
gasket and screws, without the suction port, and without the intake port, and reveals two tubular
projections threaded for receiving the 4mm screws and over which tubular projections the rubber
11/17
gasket seats, and reveals threaded portions in the lid for receiving a suction port attachment and a vent
attachment in threading engagement therewith; and schematically illustrates in part a plan
view of a top side of the second lid without the suction port and without the intake port, and reveals a
profile of the handle of the plunger for receiving a palm of a hand.
Perceived Highlighted Benefits of Bone Collection Assemblies
[ [ [ [0 0 0 01 1 1 10 0 0 01 1 1 1] ] ] ] As will be appreciated from the foregoing, the bone collection assembly is disposable and
cost effective; proficiently collects autologous bone during a surgical operation; and is easy to
construct and is simple to use.
[ [0 01 10 02 2] ] Moreover, it is believed that the bone collection assembly is less prone to clogging during
[ [0 01 10 02 2] ]
use compared to many conventional devices used for autologous bone collection. Furthermore, the
chamber of the 50cc container is much larger than the collection capacity of many conventional
devices used for autologous bone collection, and therefore can be used to collect larger amounts of
blood and bone at a single time. The can be especially advantageous during a lumbar fusion.
[ [0 01 10 03 3] ] Additionally, it is believed that the bone collection assembly need not be held by a surgeon
[ [0 01 10 03 3] ]
during the operation. Moreover, use of the plunger to compress the bone and separate the bone from
the blood products need not be performed during collection of the bone and blood products. Instead,
this can be done after detachment of the first cover following completion of the first phase of
collecting the bone and blood products. This separation step can be performed by auxiliary personnel
to the surgeon and first assist, such as a surgical tech or other staff.
[ [ [ [0 0 0 01 1 1 10 0 0 04 4 4 4] ] ] ] Still further, it is believed that the collection method has little if any loss of bone and can be
used in various operations; that the bone collection assembly will adequately separate blood products
from bone; and that the collected bone can be easily measured and utilized in procedures, such as
spinal fusions. Indeed, it is believed that the bone collection assembly can be readily utilized by
surgeons in multiple specialties and sub-specialties who require the use of autologous bone.
A Currently Preferred Bone Collection Assembly
[ [ [ [0 0 0 01 1 1 10 0 0 05 5 5 5] ] ] ] A currently preferred bone collection assembly is now described with reference to FIGS. 15-
33. In this respect, schematically illustrates a second lid 1202 attached to a container 1302 of
another bone collection assembly in accordance with another embodiment of the present disclosure.
[ [ [ [0 0 0 01 1 1 10 0 0 06 6 6 6] ] ] ] As shown in , the second lid 1202 includes a screw-on top 1201 and a plunger
assembly. Moreover, while a screw-on engagement is preferred, other engagements are contemplated,
such as a snap-fit engagement between lids and a container.
[ [ [ [0 0 0 01 1 1 10 0 0 07 7 7 7] ] ] ] The plunger assembly includes a plunger 1210 that is disposed in a first position as shown in
. The plunger 1210 comprises a handle 1212, a shaft 1214, and a press head 1216. The plunger
assembly further includes a spring 1215 that is generally coaxial with the shaft 1214 and that extends
between the handle 1212 and the top 1201. The spring 1215 biases the plunger 1210 into the first
12/17
position as shown in , and acts against a downward force A that may be manually applied to
the handle 1212 in moving the plunger 1210 from the first position to a second position, in which the
press head 1216 is located proximate a bottom of the container 1302.
[ [ [ [0 0 0 01 1 1 10 0 0 08 8 8 8] ] ] ] The screw-on top includes a suction port 1204. In contrast to the suction port 204 of the
second lid 202, which extends generally in parallel to the shaft 214 of the plunger 210, the suction
port 1204 extends to a side, transversely to the shaft 1214 of the plunger 1210. It is believed that this
orientation of the suction port 1204 is beneficial in allowing for deflection of the tubing away from
the surgical field of view.
[ [0 01 10 09 9] ] The container 1302 is configured to receive the top 1201 in threading engagement, whereby
[ [0 01 10 09 9] ]
the top 1201 is screwed onto the container 1302 and can be similarly screwed off of the container
1302. The container 1302 also preferably includes elongate protuberances or ribs 1303 that extend
between the top and bottom of the container 1302 along the exterior thereof. The ribs 1303 preferably
provide a good gripping surface for holding the container 1302 when screwing the top 1201 onto and
off of the container 1302.
[ [0 01 11 10 0] ] Moreover, the top 1201 preferably includes ribs 1203 that also provide a good gripping
[ [0 01 11 10 0] ]
surface. Furthermore, the ribs 1203 on the top 1201 preferably correspond to and align with the ribs
1303 on the container 1302 when the top 1201 is securely screwed onto the container 1302, thereby
readily visually indicating that the top 1201 is tightly screwed onto the container 1302.
[ [ [ [0 0 0 01 1 1 11 1 1 11 1 1 1] ] ] ] schematically illustrates the detachability of the second lid 1202 and the container
1302.
[ [ [ [0 0 0 01 1 1 11 1 1 12 2 2 2] ] ] ] schematically illustrates a top plan view of the second lid 1202 detached from the
container 1302 as shown in ; and schematically illustrates a side plan view of the
second lid 1202 and container 1302 of , including a cross-sectional view of the second lid
1202 taken along the line 18-18 in .
[ [ [ [0 0 0 01 1 1 11 1 1 13 3 3 3] ] ] ] schematically illustrates a plan view of the bottom of the press head 1216 and
reveals a woven metal mesh disc 1218.
[ [ [ [0 0 0 01 1 1 11 1 1 14 4 4 4] ] ] ] The disc 1218 preferably is secured to the press head 1216 in an injection molding process,
with a circumferential portion of the press head 1216 being formed about a circumferential outer
portion of the disc 1218 to thereby hold the disc within a recessed area on the underside of the press
head 1216. In this respect, in at least one preferred embodiment the press head 1216 includes a lip of
approximately 0.020 inches. In other embodiments, the disc may be glued or otherwise adhered to the
press head, or secured using mechanical fasteners.
[ [ [ [0 0 0 01 1 1 11 1 1 15 5 5 5] ] ] ] Furthermore, the disc 1218 preferably includes four openings through which alignment
protuberances or pins 1221 of the press head 1216 extend for alignment of the disc 1218 to the press
head 1216.
[ [ [ [0 0 0 01 1 1 11 1 1 16 6 6 6] ] ] ] Additionally, the disc 1218 is supported by the press head as the plunger is moved through
any contents in the container from the first position to the second position along the radially
13/17
extending, elongate areas 1223 as indicated in . These areas comprise an alternating sequence
of long and short radially extending, elongate areas 1223 spaced at equal intervals circumferentially
about the disc 1218, and correspond to elongate, radially extending support members 1225 on the
underside of the press head 1216. This support arrangement provides generally equally distributed
support of the disc 1218 during filtration of the bone from the blood while also providing a very large
filtration area (as will be appreciated, most of the surface of the disc 1218 actively filters the bone
from the blood).
[ [0 01 11 17 7] ] With further regard to the press head 1216 and omitting the disc 1218, schematically
[ [0 01 11 17 7] ]
illustrates a side plan view of the press head 1216; schematically illustrates a top plan view of
the press head 1216; and schematically illustrates a perspective view of the press head 1216.
[ [0 01 11 18 8] ] schematically illustrates a perspective view of the screw-on top 1201.
[ [0 01 11 18 8] ]
[ [0 01 11 19 9] ] schematically illustrates a bottom plan view of the screw-on top 1201;
[ [0 01 11 19 9] ]
schematically illustrates a perspective view of a cross-section of the screw-on top 1201 taken along
the line 25-25 in ; schematically illustrates a side plan view of the screw-on top 1201;
and schematically illustrates another side plan view of the screw-on top 1201.
[ [0 01 12 20 0] ] It will be seen from these drawings that the screw-on top 1201 defines passageways 1206
[ [0 01 12 20 0] ]
formed in the axial extent of the opening 1207 in the top 1201 through which the shaft 1214 of the
plunger 1210 is received. These passageways 1206 form vents when the shaft 1214 is received though
the opening 1207 and perform the same function as vent 206 in the cover 202 described above.
[ [ [ [0 0 0 01 1 1 12 2 2 21 1 1 1] ] ] ] Furthermore, each passageway 1206 includes a top portion that is generally oriented in
parallel to the axis of the opening 1207 and shaft 1214 when received therethrough; a middle portion
that is generally circumferentially oriented to the axis of the opening 1207 and shaft 1214 when
received therethrough; and a bottom portion that is generally oriented in parallel to the axis of the
opening 1207 and shaft 1214 when received therethrough. The top portion and bottom portion of each
passageway 1206 are thus offset from each other along the circumferential direction about the opening
1207. This is perhaps best seen in the passageway 1206 called out in .
[ [ [ [0 0 0 01 1 1 12 2 2 22 2 2 2] ] ] ] schematically illustrates a perspective view of a screw-on top 1101 of a first lid for
use with the container 1302 of ; schematically illustrates a bottom plan view of the
screw-on top 1101; schematically illustrates a cross-sectional view of the screw-on top 1101
taken along the line 30-30 in ; schematically illustrates a side plan view of the screw-
on top 1101; and schematically illustrates another side plan view of the screw-on top 1101.
As seen in these drawings, the screw-on top 1101 includes a suction port 1104 and an intake port

[ [ [ [0 0 0 01 1 1 12 2 2 23 3 3 3] ] ] ] As will be appreciated from the foregoing description and drawings, a bone collection
assembly in accordance with one or more aspects of the disclosure are used to efficiently and
effectively collect bone particles, bone fragments, blood and other products created during
intraoperative bone removal. The bone collection assembly separates the bone from these other
14/17
materials into a desirable autologous graft for use during bone fusion procedures. The compressed
bone obtained from using the bone collection assembly can be contoured into virtually any shape
dictated by surgical needs, whether it be on-lay grafting or interbody fusion. It is believed that the
compressed bone is viable and can be safely delivered back to the patient, decreasing the surgical
team’s reliance on expensive synthetics, allograft and remote bone harvesting.
[ [ [ [0 0 0 01 1 1 12 2 2 24 4 4 4] ] ] ] Based on the foregoing description, it will be readily understood by those persons skilled in
the art that the present disclosure is susceptible of broad utility and application. Many embodiments
and adaptations of the present disclosure other than those specifically described herein, as well as
many variations, modifications, and equivalent arrangements, will be apparent from or reasonably
suggested by the present disclosure and the foregoing descriptions thereof, without departing from the
substance or scope of the present disclosure.
