Abstract
Disclosed is a device for implantation into a bone void while minimising the potential for an increase in pressure within the bone void.
Claims16
An implantable device for insertion into a bone void, the implantable device comprising a bone substitute material and having a cylindrical body and one or more longitudinal channels extending 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;
- the one or more longitudinal channels each intersecting a surface of the device and extending to an axial centerline thereof, and being tapered such that the width of the one or more longitudinal channels opening on an outer, circumferential edge of the implantable device is greater than its width at a base thereof;
- and wherein the devices have a flat surface on an opposing longitudinal side to the one or more longitudinal channels;
- and wherein the device has convex, domed or semispherical shaped ends.
An arrangement of two or more implantable devices comprising a plurality of the devices lined up end to end, wherein each of the implantable devices comprises a bone substitute material and has a cylindrical body and one or more longitudinal channels extending the entire length of the device, where said one or more longitudinal channels allows for depressurisation of the bone void during implantation of each device;
- the one or more longitudinal channels each intersecting a surface of each device and extending to an axial centerline thereof, and being tapered such that the width of the one or more longitudinal channels opening on an outer, circumferential edge of each implantable device is greater than its width at a base thereof;
- and wherein the devices have a flat surface on an opposing longitudinal side to the one or more longitudinal channels;
- and wherein each device has convex, domed or semispherical shaped ends.
