Methods and devices for treating tissue

摘要

The invention provides a system and method for achieving the cosmetically beneficial effects of shrinking collagen tissue in the dermis or other areas of tissue in an effective, non-invasive manner using an array of electrodes. Systems described herein allow for improved treatment of tissue. Additional variations of the system include array of electrodes configured to minimize the energy required to produce the desired effect.

主权项

1. A method for treating tissue by applying energy to tissue, the method comprising:
providing an energy transfer unit comprising a plurality of electrodes each having an active area, the plurality of electrodes extending at a fixed angle relative to a tissue engaging surface of the energy transfer unit; applying the tissue engaging surface against a surface layer of tissue establish a starting point for the plurality of electrodes; advancing the plurality of electrodes into the surface layer of tissue by a uniform depth and at the fixed angle relative to the tissue engaging surface such that the active area of the electrodes extends at the oblique angle through a target layer of tissue; and applying energy to the active region to create a treatment lesion in the target layer of tissue, where a length of the treatment lesion along the active area in the target layer of tissue is larger than if the plurality of electrodes were advanced perpendicular into the surface layer of tissue.
