A biodegradable replaceable toothbrush head preferably for an electric toothbrush. The replacement head can be configured to be removably connected and operated by one or more conventional electric power/drive units. Various biodegradable materials can be used alone or in combination for constructing the replacement head and in certain embodiments the biodegradable replacement can be constructed from solely or primarily corn starch or bamboo. In another non-limiting embodiment, the biodegradable replacement head can be construction from about 60-80% polylactic acid, and about 20-40% talcum.

A toothbrush assembly having toothbrush members with biodegradable portions wherein the toothbrush members are configured to be releasably secured to a holder. The holder of the present invention includes an interior volume and is configured to receive, store and dispense a dentifrice. The holder includes a lever member at the top thereof. The toothbrush members include a lower portion and an upper portion wherein the upper portion is releasably secured to the lower portion. The upper portion is manufactured from a biodegradable plastic. The lower portion includes at least one magnet wherein the at least one magnet facilitates mounting the toothbrush member to the holder as well as to a mounting plate wherein the mounting plate is secured to a desired vertical surface. The holder includes a lever member to facilitate dispensing of the dentifrice. The upper portion includes three contiguously formed sections.

A targeted drug delivery device comprises a brush for use in delivery of one or more therapeutic agents during surgical procedures, including but not limited to, heart, chest, abdominal, brain, limb, vascular, eye, organ transplantation surgery or cancer surgical treatment. The therapeutic agent is selected from the group consisting of genetically engineered vectors or cells, proteins, stem cells, small molecule pharmaceuticals, drugs or biologics. Methods of treating diseases comprising delivering at least one therapeutic agent to a patient's organs or tissues using any one of the targeted drug delivery devices are disclosed.

Disclosed herein is a disposable, biodegradable toothbrush. The toothbrush may comprise a handle portion and a head portion coupled to the handle portion. The head portion may comprise a surface and a plurality of spaced bristles extending perpendicularly outwards from the surface of the head portion for brushing teeth. The surface of the head portion may have dehydrated dentifrice powder deposited on at least a portion of the surface. The plurality of spaced bristles may comprise a first type of bristles and a second type of bristles. Also disclosed herein is a method of producing any of the disposable, biodegradable toothbrushes described herein.

The present invention is directed to a debridement and/or implant cleaning tool 1 in which the means for cleaning 4 is made of a biodegradable material. Thus, if parts of the means for cleaning 4 come loose during use, these will be degraded by natural processes in the body and will not remain in the body and cause negative body reactions.
