TREATMENT SYSTEMS WITH FLUID MIXING SYSTEMS AND FLUID-COOLED APPLICATORS AND METHODS OF USING THE SAME

摘要

A treatment system for cooling subcutaneous lipid-rich cells in a human subject includes an applicator and a control unit. The treatment system has a cooling mode for cooling tissue and a heating mode for warming tissue. The control unit includes a circulation circuit in fluid communication with the applicator, a chiller apparatus configured to chill fluid from the applicator circulation circuit, and a heater apparatus to warmed fluid from the applicator circulation circuit. The control unit mixes the chilled fluid and/or the warmed with fluid in the applicator circulation circuit control the temperature of the fluid circulated in the applicator.

主权项

1. A treatment system for cooling subcutaneous lipid-rich cells in a subject, comprising:
an applicator configured to be in thermal communication with skin of the subject; and a control unit having a cooling state and a heating state, the control unit including
an applicator circulation circuit including a supply end in fluid communication with the applicator and a return end in fluid communication with the applicator, the applicator circulation circuit defining a flow path extending between the supply end and the return end and along which coolant flows to deliver coolant to the applicator,a chiller apparatus configured to chill coolant from the applicator circulation circuit, the chiller apparatus is configured to deliver chilled coolant to the applicator circulation circuit to reduce a temperature of coolant in the applicator circulation circuit when the control unit is in the cooling state, anda heater apparatus configured to deliver heated coolant to the applicator circulation circuit to raise the temperature of the coolant in the applicator circulation circuit when the control unit is in the heating state.
