Abstract
A cement-directing structure for use in cement-injection bone therapy includes a collapsible, self-restoring braided structure with regions of differential permeability to the bone cement. The regions of differential permeability may be provided by areas where the braided mesh density is greater or lesser than surrounding areas and/or by means of a baffle. After the structure is placed in a void within a bony structure, cement is injected into the interior of the structure then oozes out in preferred directions according to the locations of the regions of differential permeability.
Claims20
A surgical method comprising:
- inserting a device into a cavity in a patient in a first collapsed configuration;
- and
- expanding the device to a second expanded configuration in order to maintain walls of the cavity apart from each other,
- wherein the device includes a collapsible, expandable mesh structure having co-braided primary members and secondary members occupying interstices between said primary members.
A surgical method comprising:
- inserting a device into a cavity in a patient in a first collapsed configuration;
- and expanding the device to a second expanded configuration in order to maintain walls of the cavity apart from each other, wherein the device includes a flexible mesh structure having sufficient rigidity to maintain walls of the cavity apart from each other in the second expanded position, wherein the flexible mesh structure having co-braided primary members and secondary members occupying interstices between said primary members.
