Abstract
A set is provided for applying a flat, flexible two-dimensional thin-film strip into living tissue, particularly into brain tissue. The set includes the thin-film strip itself to be applied and an application tool, which is removable and mechanically connectable to the thin-film strip by a coupling device. After application of the thin-film strip in situ the application tool is removable from the tissue without residue by mechanically disengaging the coupling device itself, while leaving the thin-film strip behind.
Claims16
A set for applying a flat, flexible two-dimensional thin-film strip at a target location into a living tissue, the set comprising:
- the thin-film strip to be applied, the thin-film strip having a thin-film strip distal end and a reinforced retaining hole in the thin-film strip distal end,
- an application tool adapted to be removably insertable into the living tissue, wherein the application tool comprises an insertion needle having an inner bore and a window on one side next to its distal end opening towards the inner bore;
- and
- a coupling device disposed in the application tool, the coupling device releasably attaching the thin-film strip distal end to the application tool when the thin-film strip distal end is in the application tool, the coupling device further comprises a retaining wire designed to pass through the inner bore of the insertion needle and through the retaining hole in the thin-film strip distal end;
- wherein the reinforced retaining hole in the thin-film strip distal end and the retaining wire lies in the window during insertion of the thin-film strip into the living tissue, such that the thin-film strip is removably locked to the insertion needle;
- and
- wherein the application tool is configured to be mechanically disengageable from the thin-film strip distal end, and is subsequently removable from the living tissue without residue thereby leaving the thin-film strip at the target location in the living tissue upon removal of the application tool.
A set for applying a flat, flexible two-dimensional thin-film strip at a target location into a living tissue, the set comprising:
- the thin-film strip to be applied, the thin-film strip tapering at its distal end into a separable polyimide retaining thread;
- an application tool is adapted to be removably insertable into the living tissue, the application tool comprising a solid insertion needle having a through bore in its distal end,
- wherein the polyimide retaining thread is threaded through the through bore in the insertion needle before applying the thin-film strip and is configured to be mechanically separable from the thin-film strip by pulling on the polyimide retaining thread, and
- wherein the application tool is configured to be mechanically disengageable from the thin-film-strip distal end and is subsequently removable from the living tissue without residue thereby leaving the thin-film strip at the target location upon removal of the application tool.
A set for applying a flat, flexible two-dimensional thin-film strip at a target location into a living tissue, the set comprising:
- the thin-film strip to be applied, the thin-film strip having a reinforced retaining hole in a distal end thereof;
- and
- an application tool is adapted to be removably insertable into the living tissue,
- wherein the application tool comprises a solid insertion needle having a through bore in its distal end and a separate polyimide thread designed to be threaded through the through bore in the insertion needle and through the retaining hole in the thin-film strip and the separate polyimide thread attaches the thin-film-strip distal end to the application tool before applying the thin-film strip and is configured to be mechanically separable from the thin-film strip by pulling on the retaining thread, and
- wherein the application tool is configured to be mechanically disengageable from the thin-film-strip distal end and is subsequently removable from the living tissue without residue thereby leaving the thin-film strip at the target location upon removal of the application tool.
A set for applying a flat, flexible two-dimensional thin-film strip at a target location into a living tissue, the set comprising:
- the thin-film strip to be applied, the thin-film strip having a reinforced retaining hole in a distal end thereof;
- an application tool is adapted to be removably insertable into the living tissue,
- wherein the application tool comprises a solid insertion needle having two through bores spaced apart longitudinally in its distal end and a separate polyimide thread threaded through the two through bores in the insertion needle in a loop shape through the retaining hole of the thin-film strip before applying the thin-film strip, such that the two through bores form a guide for the looped thread, and
- wherein the application tool is configured to be mechanically disengageable from the thin-film-strip distal end and is subsequently removable from the living tissue without residue thereby leaving the thin-film strip at the target location upon removal of the application tool.
