Abstract
A tissue treatment device has a flexible treatment portion that includes one or more parts and holes arranged in an openwork. A treatment area is defined in the openwork. The treatment portion is deployed such that the treatment area is positioned over tissue to be treated. The openwork minimizes contact between the tissue treatment device and the tissue being treated. A flexible cover is secured against the flexible treatment portion to close the holes and form a treatment volume in the openwork. The minimal contact between the tissue treatment device and the tissue being treated promotes a desired clinical objective.
Claims45
A treatment device, comprising:
- a delivery piece with a raised portion and lateral portions defining a rectangular space;
- a flexible treatment portion with a first surface, a second surface to contact tissue being treated, and one part with a sinuous shape defining a repeating, linear sequence of openings;
- the openings extending through the treatment portion from the first surface to the second surface;
- a sheet of flexible material received against the first surface and forming a treatment volume with the plurality of openings;
- and,
- one or more adhesive portions to secure the sheet of flexible material over the first surface;
- the sheet of flexible material and the treatment portion being received within the rectangular space such that the sheet of flexible material is sandwiched between the flexible treatment portion and the raised portion;
- the delivery piece being removable from the sheet of flexible material and the treatment portion when the flexible treatment portion contacts the tissue being treated.

- a flexible treatment portion with a first surface, a second surface and one or more parts;
- a plurality of openings opening through the treatment portion, from the first surface to the second surface;
- at least one part and the openings forming an openwork;
- a sheet of flexible material received against the openwork and forming a treatment volume with the plurality of openings;
- adhesive to act between the second surface and tissue;
- and,
- a single delivery piece with a raised portion and lateral portions defining a rectangular space receiving the sheet of flexible material and the treatment portion and with enough rigidity to maintain the rectangular space while the treatment device is being handled;
- the delivery piece being removable from the sheet of flexible material and the treatment portion when the flexible treatment portion contacts tissue.
