Abstract
The present invention relates to an implantable, disposable barrier disc to be used in negative pressure treatment of wounds, in particular sternotomy wounds, wherein the barrier disc consists of a rigid material withstanding a negative pressure of at least −50 mmHg without causing deformation to the barrier disc, and that the barrier disc is perforated to allow drainage of wound fluid through said barrier disc.
Claims14
An implantable, barrier disc for insertion over exposed organs or tissues during negative pressure treatment of wounds (NPWT), for preventing exposed organs or tissues from being exposed to harmful effects of the negative pressure, wherein the barrier disc is substantially flat, and comprises a rigid material withstanding a negative pressure of at least −50 mmHg, without causing deformation to the barrier disc, and that the barrier disc is perforated to allow drainage of fluid through said barrier disc, and has flexible edges that do not damage surrounding vital structures.
An implantable barrier disc for placement over exposed organs and tissue during negative pressure treatment of wounds for preventing exposed organs or tissues from being exposed to harmful effects of the negative pressure, wherein the barrier disc comprises a rigid material withstanding a negative pressure of at least −50 mmHg without causing deformation to the barrier disc, and is perforated to allow drainage of fluid through said barrier disc and is flexible to not damage surrounding tissue structures.
A method for protecting organs or tissue during negative pressure wound therapy comprising:
- providing an implantable, substantially flat, rigid and perforated barrier disc;
- and
- inserting an implantable, substantially flat, rigid and perforated barrier disc over the exposed organ for preventing the exposed organ or tissue from being exposed to harmful effects of the negative pressure, the said disc withstanding a negative pressure of at least −50 mmHg without causing deformation to the said disc and having flexible edges for not damaging surrounding tissues.
