Ultrasonic subcutaneous dissection tool incorporating fluid delivery

A dissection tool, comprising:

• a handle;
• an ultrasonic transducer connected to the handle, the ultrasonic transducer having a proximal end and a distal end, the proximal end of the ultrasound transducer coupled to the handle;
• an elongated dissecting member having a proximal end and a distal end, the elongated dissecting member extending from the distal end of the ultrasonic transducer;
• and
• a fluid channel system extending from at least the proximal end of the elongated dissecting member to the distal end of the elongated dissecting member, the fluid channel system terminating in a port system.

A dissection tool, comprising:

• a handle having a proximal end and a distal end;
• an elongated dissecting member having a proximal end and a distal end, the elongated dissecting member extending from the distal end of the handle;
• an ultrasonic transducer provided at the distal end of the elongated dissecting member;
• and
• a fluid channel system extending from at least the proximal end of the elongated dissecting member to the distal end of the elongated dissecting member, the fluid channel system terminating in a port system.

A method of dissecting subcutaneous tissue, comprising:

• providing an ultrasonic dissection tool having a fluid delivery system;
• dissecting subcutaneous tissue with the ultrasonic dissection tool to create a path in the subcutaneous tissue;
• and
• delivering a fluid from the dissection tool during subcutaneous tissue dissection via a fluid delivery system.

A dissection tool, comprising:

• an ultrasonic transducer;
• means, coupled to the ultrasonic transducer, for dissecting subcutaneous tissue;
• and
• means for delivering a fluid through or along the dissecting means and to tissue subject to dissection.

A dissection system, comprising:

• a pump;
• a fluid reservoir adapted to provide a fluid to the pump;
• a tube;
• and
• a dissection tool comprising an elongated dissecting member, an ultrasonic transducer coupled to the elongated dissecting member, and a fluid channel system extending between proximal and distal ends of the elongated dissecting member, wherein the tube fluidly connects the dissection tool with the pump.

A method of dissecting subcutaneous tissue, comprising:

• ultrasonically dissecting subcutaneous tissue to create a path in the subcutaneous tissue;
• delivering a fluid to the subcutaneous tissue during subcutaneous tissue dissection;
• and
• impelling the fluid into the subcutaneous tissue via sonophoresis.
