In various embodiments, a surgical instrument is provided that may comprise an end effector for performing a surgical procedure on tissue, for example. The end effector may comprise at least one energy delivery surface and heat dissipation means for dissipating heat from at least a portion of the end effector. For example, in at least one embodiment, the end effector may comprise a first jaw, a second jaw, and a cutting member. The cutting member may comprise a cutting surface and a body, which may define a cavity and at least one opening communicating with the cavity. A fluid may be moved through the cavity to and/or from the opening(s). Additionally, in at least one embodiment, a surgical instrument's end effector may comprise a first jaw, a second jaw, a cutting member, and at least one heat pipe. Various other heat dissipation means are also disclosed.

A method and system are disclosed for opening a workspace inside a lumen of a living creature are disclosed. Anchors may be affixed to opposite ends of the workspace. An extender may be distance anchors apart while they are affixed to the walls of the workspace. Distancing the anchors may unfold and/or stretch the lumen in the region of the workspace.

Systems for treating a subject's tissue can include a thermally conductive cup with vacuum features configured to facilitate removal of air located between the cup and the subject's skin. The vacuum features can extend along cup to provide airflow paths to a vacuum port. The applicator can cool and/or heat the retained tissue to affect targeted tissue. After the treat period, the vacuum can be reduced or stop and the applicator can be removed from the subject.

Methods are provided herein for affecting a region of a subject's body, comprising exposing the region to a cooling element under conditions effective to cool subcutaneous adipose tissue in said region; and increasing the blood flow rate to the cooled tissue by exposing the tissue to an energy source. Methods are also provided for treating subcutaneous adipose tissue in a region of a subject's body, comprising exposing said region to a cooling element under conditions effective to cool said tissue; and exposing the tissue to an energy source to increase the blood flow rate to the cooled tissue, thereby stimulating reperfusion in, and/or causing an ischemia-reperfusion injury to, the cooled tissue.

A probe intended to be at least partially implanted in a living being, with a view to locally cooling at least one region of the living being, this probe notably including a cooling member present at its distal end, which member is intended to make contact with the region to be cooled, and a thermoelectric cooling module including a cold region making contact with the cooling member.

A method for treating a skin lesion can include lowering a temperature of a treatment site to a temperature range sufficient to induce vasoconstriction in a dermis of the treatment site and administering a laser light through a medium to the skin lesion while maintaining the temperature of the treatment site within the temperature range. The medium can include a first portion and a second portion, where the laser light is transmitted through the first portion and the second portion sequentially, the second portion includes a contact surface for contacting the treatment site, and the second portion has a higher thermal conductivity than the first portion. The method can further include identifying the skin lesion and analyzing one or more characteristics of the skin lesion.

According to one aspect of the present invention, provided is a beauty medical device comprising: a handpiece body having an ultrasonic emission surface prepared at one end; an ultrasonic generation unit which is provided inside the handpiece body and which generates an ultrasonic wave so as to emit same at the skin through the ultrasonic emission surface; and a high frequency generation unit disposed on the circumference of the ultrasonic emission surface at one end of the handpiece body so as to generate a high frequency.

A portable depilation instrument includes a shell, and a depilation mechanism and a heat dissipation mechanism inside the shell. The shell is provided with at least two outlets and one inlet, the shell introduces an external cooling medium from the inlet, the heat dissipation mechanism includes a heat conductive component, the depilation mechanism includes a refrigeration element and an emitter, the heat conductive component isolates the refrigeration element from the emitter in two mutually sealed channels, namely, a first channel and a second channel, the first channel and the second channel are respectively in communication with two outlets, and one of the outlets allows the first channel or the second channel to pass through inside of the entire shell from one end to the other end. Due to complete isolation and a push force, air can be discharged only from a respective corresponding outlet after a heat exchange.

The illustrated embodiments include an apparatus to reduce or eliminate full thickness injury in tissue and to deform tissue which includes a probe or mechanism for deforming tissue, and a subsystem for selectively cooling and/or heating tissue while deformation is of the tissue is being performed. The illustrated embodiments of the invention also extend to a method to reduce or eliminate full thickness injury in tissue and to deform tissue including the steps of deforming tissue, and selectively cooling and/or heating tissue while deformation of the tissue is being performed.

Dermatological systems and methods for providing a therapeutic laser treatment using a handpiece delivering one or more therapeutic laser pulses to a target skin area along a first optical path, and sensing the temperature of the target skin area based on infrared energy radiating from the target skin area along a second optical path generally counterdirectional to the first optical path, and sharing a common optical axis with the first optical path for at least a portion of the first and second optical paths. The handpiece may also provide contact cooling for a first skin area comprising the target skin area.
