Fluid skin treatment systems and methods
Devices and methods for dermatology and more particularly to fluid enhanced skin treatment system for skin rejuvenation that can use an abrasive probe for removing epidermal layers while contemporaneously providing for the infusion of therapeutic fluids into the skin.
1. A method of treating a skin of a patient, the method comprising:
positioning a surface of a distal tip of an abrasion device against the skin of the patient, where the distal tip comprises a plurality of spaced apart flexible elements extending on the surface of the distal tip from a periphery of the surface towards a central shaft portion of the surface, where the spaced apart flexible elements include an abrasive surface;
actuating the spaced apart flexible elements by rotating the central shaft portion to displace the spaced apart flexible elements such that the surface of the distal tip reciprocates in a rotational motion independently of a housing of the abrasion device to cause the abrasive surface of the distal tip to remove a surface of the skin of the patient;
delivering a fluid to the surface of the distal tip such that the fluid flows between the spaced apart flexible elements to contact the skin of the patient;
providing a negative pressure between the spaced apart flexible elements to aspirate fluid and tissue away from the skin of the patient.
2. The method of claim 1 , where the plurality of spaced-apart flexible elements extends outward from a center hub of the distal tip such that the reciprocating rotational motion of the distal tip causes the spaced apart flexible elements to move in an arc over the skin of the patient.
3. The method of claim 2 , where the spaced-apart flexible elements extend in a partial spiral shape outward from the center hub of the distal tip and where actuating the spaced apart flexible elements in the reciprocating rotational motion causes the spiral shape to deform or twist.
4. The method of claim 2 , where the plurality of spaced-apart flexible elements further include a plurality of ports therein, where the fluid is delivered through at least one port of the plurality of ports.
5. The method of claim 4 , where each port of the plurality of projecting elements is fluidly coupled to a microchannel extending within the distal tip.
6. The method of claim 1 , where the plurality of spaced apart elements comprise a lower durometer material located at a distal end.
7. The method of claim 1 , where the distal tip comprises a plurality of actuator magnets and where actuating the spaced apart flexible elements comprises rotating a plurality of drive magnets to cause the plurality of actuator magnets to cause reciprocating rotational motion of the surface of the distal tip where the plurality of drive magnets and the plurality of actuator magnets are offset from a central axis of the central portion.
8. The method of claim 7 , further comprising adjusting a distance between the actuator magnets and the drive magnets to increase an actuation force applied during actuating the spaced apart flexible elements.
9. The method of claim 7 , wherein the abrasion device comprises a switch located on a body, the method further comprising using the switch to adjust either:
an actuation force applied during actuating the spaced apart flexible elements;
a frequency of the actuation of the spaced apart flexible elements; and/or
delivery of the fluid to the surface of the distal tip.
10. A method of treating a skin of a patient, the method comprising:
positioning a surface of a distal tip of an abrasion device against the skin of the patient, where the distal tip comprises a plurality of spaced apart flexible elements extending on the surface of the distal tip, where the spaced apart flexible elements include an abrasive surface;
actuating the spaced apart flexible elements such that the surface of the distal tip reciprocates in a rotational motion to cause the abrasive surface of the distal tip to remove a surface of the skin of the patient;
where the distal tip comprises a plurality of actuator magnets and where actuating the spaced apart flexible elements comprises rotating a plurality of drive magnets to cause the plurality of actuator magnets to cause reciprocating rotational motion of the surface of the distal tip where the plurality of drive magnets and the plurality of actuator magnets are offset from a central axis of the central portion
delivering a fluid to the surface of the distal tip such that the fluid flows between the spaced apart flexible elements to contact the skin of the patient;
providing a negative pressure between the spaced apart flexible elements to aspirate fluid and tissue away from the skin of the patient.
11. The method of claim 10 , further comprising adjusting a distance between the actuator magnets and the drive magnets to increase an actuation force applied during actuating the spaced apart flexible elements.
12. The method of claim 10 , wherein the abrasion device comprises a switch located on a body, the method further comprising using the switch to adjust either:
an actuation force applied during actuating the spaced apart flexible elements;
a frequency of the actuation of the spaced apart flexible elements; and/or
delivery of the fluid to the surface of the distal tip.
