A personal care appliance includes a housing having a first end and a second end located opposite and distal the first end, a treatment head member coupled to the first end of the housing, a sonic motor provided in the housing and being structured to oscillate the head member, and a drainage system comprising a pump provided in the housing, a first conduit fluidly coupled to the pump and the head member, and a second conduit fluidly coupled to the pump and the second end of the housing.

A distance between a surface of a treatment head and tip opening of a skin treatment hand piece is adjustable. In an implementation, the distance is adjusted by moving the tip opening relative to the treatment head surface. Different distances may be used to treat different skin types, problems, and conditions. In an implementation, the hand piece includes a fluid delivery and a vacuum or suction mechanism to provide various therapeutic benefits to the skin.

A surgical instrument for treating tissue includes an articulating elongated shaft (14), a drive shaft (28) extending through the elongated shaft and configured to rotate about a longitudinal axis defined by the drive shaft, and an end effector assembly (100) coupled to a distal end portion of the elongated shaft. The end effector assembly includes a jaw member (110) and a blade member (112) configured to rotate in response to a rotation of the drive shaft to treat tissue disposed between the jaw member and the blade member.

Methods and devices described herein facilitate ablation patterns on the heart within a pericardial sac and without opening or deflating the lungs.

An apparatus for treating skin has a console with a user input device and a handpiece assembly. The handpiece assembly is configured to treat skin. A fluid line provides fluid communication between the console and the handpiece assembly. A manifold system is coupled to the console and controlled by the user input device. The manifold system is configured to hold releasably a plurality of fluid sources and deliver fluid from at least one of the plurality of fluid sources to the handpiece assembly.

According to some embodiments, a method of treating a skin surface of a subject comprises heating a skin surface, abrading native skin tissue of a subject using a microdermabrasion device, wherein using the microdermabrasion device comprises moving the microdermabrasion device relative to the skin surface while simultaneously delivering at least one treatment fluid to the skin surface being treated and cooling the abraded skin surface.

The present invention provides topical dosages and formulations of lidocaine and pharmaceutically acceptable salts thereof, which are efficacious, chemically stable and physiologically balanced for safety and efficacy, particularly for debridement pain, and increase the duration of pain relief, and thereby provide more effective treatment to chronic open wounds, particularly those in non-mucosal tissue.

Systems and methods involve abrading a patient lung airway wall to reduce mucus production therein. Exemplary techniques include rotationally and/or linearly oscillating an abrasive material against the airway wall so as to damage mucus producing tissues, for example by removing goblet cells, while destroying less than the entire airway wall. The abrasive material may be present on the surface of an expandable balloon body or another expandable device, which can be delivered to the patient treatment site via a bronchoscope. In some cases, the abrasion techniques can cause cell damage or death at a controlled or predetermined tissue depth.

A catheter system includes a catheter that includes an outer shaft and a rotatable inner shaft having a drill tip. The catheter can be configured to bend laterally when the inner shaft is rotating within the other shaft for maneuvering within a blood vessel, for example, as the drill tip crosses an occlusion. Catheter bending can be activated by translating the inner shaft relative to the outer shaft in a distal direction, proximal direction, or both. The outer shaft may include a locking feature to rotatably lock the inner shaft with the outer shaft and allowing bidirectional lateral bending of the catheter. The inner shaft can include one or more imaging sensors for collecting images outside of the catheter. The inner shaft may be removable from the outer shaft, for example after an occlusion is crossed, to allow insertion of a guidewire or other device within the outer shaft.

The invention is a device, system, and method for repairing heart valve function, which may include bisecting native valve leaflets for improved deployment of a prosthetic heart valve in the native valve annulus. The invention may include a catheter having a cutting element shaft with a cutting element configured to puncture a valve leaflet and/or make a controlled cut through the leaflet. The device may have an extendable foot configured to be positioned on an opposite side of the valve leaflet from the cutting element shaft. The device may include magnets to guide the cutting element and/or cutting element shaft in proper alignment with the extendable foot and to hold the elements in place during leaflet bisection.
