System and method for endovenous treatment of varicose veins with mid infrared laser
This invention is an improved method and device for treating varicose veins 200 or the greater saphenous vein 202. The method comprises the use of infrared laser radiation in the region of 1.2 to 1.8 um in a manner from inside the vessel 200 or 202 such that the endothelial cells of the vessel wall 704 are damaged and collagen fibers in the vessel wall 704 are heated to the point where they permanently contract, the vessel 200 or 202 is occluded and ultimately resorbed. The device includes a laser 102 delivered via a fiber optic catheter 300 that may have frosted or diffusing fiber tips 308. A motorized pull-back device 104 is used, and a thermal sensor 600 may be used to help control the power required to maintain the proper treatment temperature.
Aesthetic method of biological structure treatment by magnetic field
In combined methods for treating a patient using time-varying magnetic field, treatment methods combine various approaches for aesthetic treatment. A magnetic field generating device is placed proximate to a body region of the patient. The magnetic field generating device generates a time-varying magnetic field with a magnetic flux density in a range of 0.5 to 7 Tesla. The time-varying magnetic field is applied to the body region of the patient in order to cause a contraction of a muscle within the body region. A second therapy may be used by applying one or more of optical waves, radio frequency waves, mechanical waves, negative or positive pressure or heat to the body region of the patient.
DEVICES, SYSTEMS, AND METHODS FOR COOLING A SURGICAL INSTRUMENT
A surgical system includes an ultrasonic surgical instrument and a cooling module. The instrument includes a waveguide defining a blade and having a lumen, an inflow conduit disposed in communication with the lumen and configured to supply fluid to the lumen, and a return conduit disposed in communication with the lumen and configured to receive fluid from the lumen. The cooling module includes a pump assembly operably coupled to the inflow and return conduits and configured to pump fluid through the inflow conduit, into the lumen, and back through the return conduit for cooling the blade. The cooling module also includes at least one sensor configured to sense a property of the fluid pumped into the inflow conduit and/or a property of the fluid returned from the return conduit, and a controller configured to control the pump assembly according to the sensed property(s).
MEDICAL DEVICE
A medical device includes a heating element and at least one multifunctional wire coupled to the heating element. The multifunctional wire provides current for both heating the heating element and for determining the temperature of the medical device as a thermocouple. The heating element is further coupled to one or more additional wires for completing both a heating circuit and a thermocouple circuit in combination with the multifunctional wire. In one form, the multifunctional wire and a thermocouple return wire is coupled to a first end of the heating element and heating return wire is coupled to a second end of the heating element. In another form, a first multifunctional wire is coupled to the first end of the heating element, and a second multifunctional wire is coupled to the second end of the heating element.
APPARATUS, SYSTEMS AND METHODS FOR MINIMALLY INVASIVE DISSECTION OF TISSUES
Electrosurgical lysing devices and related systems and methods. In some embodiments, the lysing device may comprise a lysing tip comprising a plurality of beads and at least one lysing member, such as a lysing rod, defining at least one lysing segment extending between each pair of adjacent beads. The at least one lysing member may extend through a tunnel extending at least partially through each of the plurality of beads so as to define the at least one lysing segment between each pair of adjacent beads.
METHODS, DEVICES, AND SYSTEMS FOR NON-INVASIVE DELIVERY OF MICROWAVE THERAPY
Methods, apparatuses and systems are provided for non-invasive delivery of microwave therapy. Microwave energy may be applied to epidermal, dermal and subdermal tissue of a patient to achieve various therapeutic and/or aesthetic results. In one embodiment, the microwave energy is applied to a target tissue via an energy delivery applicator connected to an energy generator. The energy delivery applicator may comprise one or more antennas, including monopole, dipole, slot and/or waveguide antennas (among others) that are used to direct the microwave energy to the target tissue. The energy delivery applicator may also comprise a cooling element for avoiding thermal destruction to non-target tissue and/or a suction device to localize thermal treatment at specific portions of a skin fold.
FLEXIBLE CIRCUITS FOR ELECTROSURGICAL INSTRUMENT
The disclosure provides a method of manufacturing a flexible circuit electrode assembly and an apparatus manufactured by said method. According to the method, an electrically conductive sheet is laminated to an electrically insulative sheet. An electrode is formed on the electrically conductive sheet. An electrically insulative layer is formed on a tissue contacting surface of the electrode. The individual electrodes are separated from the laminated electrically insulative sheet and the electrically conductive sheet. In another method, a flexible circuit is vacuum formed to create a desired profile. The vacuum formed flexible circuit is trimmed. The trimmed vacuum formed flexible circuit is attached to a jaw member of a clamp jaw assembly.

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.
Methods of treating nasal airways
A device is described for treating a nasal airway by modifying a property of a nasal tissue of or near a nasal valve of the airway, without using a surgical incision or an implant, to decrease airflow resistance or perceived airflow resistance in the nasal airway. Various embodiments include an elongate shaft, a bipolar radiofrequency delivery member extending from one end of the shaft, and a handle attached to the elongate shaft at an opposite end from the radiofrequency delivery member. The radiofrequency delivery member is sized to be inserted into a nose and configured to at least temporarily deform the nasal tissue and deliver radiofrequency energy. The radiofrequency delivery member includes two rows of protruding electrodes disposed on a tissue contact surface, and the device is configured to deliver radiofrequency energy from one row of electrodes to the other row of electrodes.
