Abstract
Disclosed herein are apparatuses, kits, and methods for treating skin, such as skin tightening, e.g., reducing skin laxity, for treating conditions that would benefit from tissue area or volume reduction, skin restoration, skin tightening, skin lifting, and/or skin repositioning, and/or for generally improving skin function or appearance. Such apparatuses, kits, and methods include one or more hollow needles each having at least one prong and a mechanism for removing skin tissue portion(s) from the hollow needle(s).
Claims148
An apparatus for producing a cosmetic effect in a skin tissue, comprising:
- at least one hollow needle comprising at least a first prong provided at a distal end of the hollow needle,
- wherein an angle between a lateral side of the first prong and a longitudinal axis of the hollow needle is at least about 20 degrees, and
- wherein the hollow needle is configured to remove a portion of the skin tissue when the hollow needle is inserted into and withdrawn from the skin tissue.
An apparatus for producing a cosmetic effect in a skin tissue, comprising:
- at least one hollow needle comprising at least a first prong provided at a distal end of the hollow needle,
- wherein the first prong comprises a flat tip having at least two dimensions, and
- wherein the hollow needle is configured to remove a portion of the skin tissue when the hollow needle is inserted into and withdrawn from the skin tissue.
A hollow needle comprising at least a first prong provided at a distal end of the hollow needle,
- wherein an angle (α) between a lateral side of the first prong and a longitudinal axis of the hollow needle is at least about 20 degrees, and
- wherein the hollow needle is configured to remove a portion of skin tissue when the hollow needle is inserted into and withdrawn from skin tissue.
A hollow needle comprising at least a first prong provided at a distal end of the hollow needle,
- wherein the first prong comprises a flat tip having at least two dimensions, and
- wherein the hollow needle is configured to remove a portion of skin tissue when the hollow needle is inserted into and withdrawn from skin tissue.
A needle assembly comprising a hollow needle, a z-actuator, and a tissue removal tool, wherein the hollow needle comprises at least a first prong provided at a distal end of the hollow needle and wherein an angle (α) between a lateral side of the first prong and a longitudinal axis of the hollow needle is at least about 20 degrees.
A needle assembly comprising a hollow needle, a z-actuator, and a tissue removal tool, wherein the hollow needle comprises at least a first prong provided at a distal end of the hollow needle and wherein the first prong comprises a flat tip having at least two dimensions.
