Abstract
The present invention relates generally to a device and method for treating tissues of the central nervous system and more particularly, but not exclusively, to a device and method for treating the brain tissue.
Claims32
A method for treating damaged central nervous system tissue using sub-atmospheric pressure, comprising:
- a. positioning a sub-atmospheric pressure transmission element proximate the damaged central nervous system tissue to be treated, the transmission element comprising an open-cell porous material;
- b. sealing the transmission element about the damaged central nervous system tissue to prevent gaseous communication between the damaged central nervous system tissue and the atmosphere;
- and
- c. applying sub-atmospheric pressure through the transmission element to the damaged central nervous system tissue.
A method of manufacturing a cast bioabsorbable material, the method comprising the steps of:
- a. preparing a solution comprising a bioabsorbable material and a pore forming precursor;
- b. depositing the solution in a mold;
- and
- c. removing the pore forming precursor from the molded solution to provide a cast bioabsorbable material comprising an open-cell pore structure configured to prevent the growth of central nervous system tissue therein.
A method of manufacturing an electrospun bioabsorbable material, the method comprising the steps of:
- a. preparing a solution comprising a polymer;
- and
- b. electrospinning the solution to provide an electrospun bioabsorbable material comprising an open-cell pore structure configured to prevent the growth of central nervous system tissue therein.
A method of manufacturing a printed bioabsorbable material, the method comprising the steps of:
- a. preparing a mixture comprising a bioabsorbable material;
- and
- b. printing the mixture to provide a printed bioabsorbable material comprising an open-cell pore structure configured to prevent the growth of central nervous system tissue therein.
