Abstract
A method for cleaning a surface that is selected from at least one of a medical device surface and a soft tissue surface includes the steps of: contacting the surface with bristles of a moving brush head that is part of a powered hand-held device; and dispensing onto the surface an irrigation fluid through the brush head and a dispensing opening formed along the brush head.
Claims32
A powered hand-held device for cleaning bacteria and biofilm from
- a surface of an implantable medical device comprising:
- a handle having a distal end;
- a brush head that is detachably coupled to the distal end of the handle, the brush head having a movable bristle plate from which a plurality of bristles extend outwardly;
- wherein the hand-held device has at least two operating modes including an oscillation operating mode and a sonication operating mode, each of the oscillation operating mode and the sonication operating mode having a plurality of different operating speeds, wherein in the oscillation operating mode, the movable bristle plate oscillates between 7,000 to 36,000 movements per minute and wherein in the sonication operating mode, the movable bristle plate vibrates to generate high frequency waves between 20 kHz and 20 MHZ;
- an irrigation conduit formed through the handle and the brush head, the irrigation conduit terminating in a dispensing outlet formed along an exposed surface of the movable bristle plate;
- wherein in the oscillation operating mode, irrigation fluid is dispensed through the irrigation conduit at a first pressure and wherein in the sonication operating mode, irrigation fluid is dispensed through the irrigation conduit at a second pressure that is less than the first pressure.
A kit for cleaning bacteria and biofilm from both a surface of a medical device and soft tissue at a surgical site comprising:
- a powered handle having a distal end, wherein the powered handle has an oscillation operating mode and a sonication operating mode;
- and
- a plurality of brush heads each of which is configured to be detachably coupled to the distal end of the handle, the plurality of brush heads including a first brush head that includes first bristles and a second brush head that includes second bristles;
- wherein the first brush head includes a movable first bristle plate from which the first bristles extend and a bendable neck portion that can be bent into and can hold a plurality of different bent positions;
- an irrigation conduit formed through the handle and the brush head, the irrigation conduit terminating in a dispensing outlet formed along an exposed surface of the movable bristle plate;
- wherein in the oscillation operating mode, irrigation fluid is dispensed through the irrigation conduit at a first pressure and wherein in the sonication operating mode, irrigation fluid is dispensed through the irrigation conduit at a second pressure that is less than the first pressure.
