摘要：
A device 10 for implantation into a bone void, while minimizing the increase in pressure within the bone void, comprises a bone replacement material and has one or more longitudinal channels 30 which extend substantially the entire length of the device; the channels allowing for depressurization of the bone void during implantation of the device, for example by allowing for displacement and/or exit of the void contents. In a second embodiment a kit of parts for the production and delivery of implantable devices 10 to an intramedullary canal of a patient includes a multi-cavity flexible mould mat (60, Fig 3B), a guide tube (170, Fig 5), a pusher (110, Fig 5) for facilitating the implantation of the devices, a bone substitute powder component and a liquid component, together with apparatus for mixing the components and dispensation of the mixed components into the cavities of the mould mat, where it is allowed to cure or set.
权利要求：
CLAIMS
1. An implantable device for insertion into a bone void, the implantable device
comprising a bone replacement material and having one or more longitudinal
channels extending substantially the entire length of the device, where said
one or more longitudinal channels allows for depressurisation of the bone void
during implantation of the device.
2. An implantable device according to claim 1 where the one or more
longitudinal channels allows for the displacement and/or exit of the void
contents.
3. An implantable device according to claim 1 or claim 2 where the one or more
longitudinal channels tapers in width from the exterior circumference towards
1ts central axis.
4. An implantable device according to claim 3, wherein the one or more
longitudinal channels has a taper angle of about 10 degrees to about 145
degrees.
5. An implantable device according to claim 4 where the taper angle of one or
more longitudinal channels is from about 20 degrees to about 50 degrees.
6. An implantable device according to any preceding claim where an opposing
surface to one or more longitudinal channels has a flat surface.
7. An implantable device according to any preceding claim, wherein the device
has a substantially capsule shape, having convex, domed or semispherical
shaped ends and one or more longitudinal channel intersecting the surface of
the device and extending the full length of the device and also extending
towards the device centreline.
8. An implantable device according to any preceding claim where the
displacement of the void contents reduces the pressure within the void. 9. An implantable device according to any preceding claim, wherein the device
comprises bone substitute material.
10. An implantable device according to any preceding claim, where the void can
be within an intramedullary canal of a patient.
11. An implantable device according to claim 10, where the void can be a defect
in bone.
12. An arrangement of two or more implantable devices according to any
preceding claim, comprising a plurality of the devices lined up end to end. 13. An arrangement according to claim 12, wherein the longitudinal channels are
axially aligned with each other.
14. An arrangement according to claim 12, wherein the longitudinal channels are
not axially aligned with each other.
15. An arrangement according to any of claims 12-14, wherein the arrangement is
located in an intramedullary canal of a patient.
16. A method of making an implantable device according to any of claims 1-11,
wherein the implantable device is made by either casting the implantable
device in a mould, or by 3D printing.
17. A kit of parts for the production and delivery of implantable devices to an
intramedullary canal of a patient; the kit of parts including a multi-cavity
flexible mould mat, a guide tube, a pusher that facilitates implantable devices
being freely inserted into the intramedullary canal, a bone substitute powder
component and liquid component, together with apparatus to enable mixing of
the components and dispensation of the mixed components to cavities in the
mould mat, where it is allowed to cure or set.
18. A kit of parts according to claim 17, wherein the guide tube and/or pusher are
non-rigid.
19. A kit of parts according to claim 18, wherein the guide tube is filled with one
or more implantable devices.
20. An implantable device, arrangement, method or kit substantially as described
herein in the description and drawings.
