Provided is a flex-PCB catheter device that is configured to be inserted into a body lumen. The flex-PCB catheter comprises an elongate shaft, an expandable assembly, a flexible printed circuit board (flex-PCB) substrate, a plurality of electronic components and a plurality of communication paths. The elongate shaft comprises a proximal end and a distal end. The expandable assembly is configured to transition from a radially compact state to a radially expanded state. The plurality of electronic elements are coupled to the flex-PCB substrate and are configured to receive and/or transmit an electric signal. The plurality of communication paths are positioned on and/or within the flex-PCB substrate. The communication paths selectively couple the plurality of electronic elements to a plurality of electrical contacts configured to electrically connect to an electronic module configured to process the electrical signal. The flex-PCB substrate can have multiple layers, including one or more metallic layers. Acoustic matching elements and conductive traces can be includes in the flex-PCB substrate.

Embodiments of the present disclosure provide a grounding cuff having a flexible body and an inflatable bladder disposed within the flexible body. The inflatable body is configurable to an inflated state and a deflated state. In the inflated stated, the inflatable bladder applies pressure to the grounding cuff to provide and maintain improved contact between the ground cuff and skin of a patient. Additionally, the inflatable bladder includes an inlet configured to receive a fluid from a hose, the inflatable bladder configured to the inflated state based on the fluid received via the hose. The grounding cuff may include a grounding pad coupled to a ground terminal to extract energy from the patient during a medical therapy, such as ablation therapy. The inflatable bladder may be configured to the inflated state to promote strong contact between the grounding pad and skin of the patient.

A surgical system drape incudes: a sheath having an interior cavity sized to cover a portion of a surgical system manipulator; an adaptor coupled to the sheath and including a manipulator interface and an instrument interface, the manipulator interface configured to couple with a drive interface of the manipulator, the instrument interface being configured to couple with a drive interface of a surgical instrument mounted to the manipulator; and a fluid conduit coupled to the sheath and extending within the interior cavity of the sheath, the fluid conduit configured to receive a flow of cooling fluid at a fluid port and convey the fluid along the interior cavity of the sheath to cool a component of a portion of the manipulator.

A hair-removal apparatus is provided, which includes a main body, a housing, a first air-inlet channel and a second air-inlet channel. The main body is accommodated in the housing and includes a heat-generating assembly and a refrigerating assembly. The first air-inlet channel communicates the refrigerating assembly with ambiance to absorb external air and dissipate heat from the refrigerating assembly, and the second air-inlet channel communicates the heat-generating assembly with ambiance to absorb external air and dissipate heat from the heat-generating assembly. The hair-removal apparatus is provided with two independent air inlet channels, which effectively enhances the heat dissipation performance of the hair-removal apparatus and improves the durability and safety of the hair-removal apparatus.

Featured is a surgical instrument including an end effector such as a rotating cutting implement and a heat transfer mechanism such as a cooling device, such as can include a phase change device, such as can be configured to absorb heat energy during the use of such a rotating cutting implement. The heat transfer mechanism can be configured so the absorbed heat energy is communicated to an external heat sink. Such a heat transfer mechanism can include a heat pipe, e.g., a scintered or wick type heat pipe. The heat energy is absorbed at one end of the heat pipe to minimize the potential for damage to the tissue and the like at and/or about the surgical site. Also featured are a surgical apparatus embodying such a surgical instrument and surgical or medical methods or procedures for manipulating, rotatably cutting, grinding, abrading or debriding tissue, bone or other structures or components of a mammalian body using such surgical instruments or surgical apparatus.

A device for therapeutic neuromodulation in a nasal region can include, for example, a shaft and a therapeutic element at a distal portion of the shaft. The shaft can locate the distal portion intraluminally at a target site inferior to a patient's sphenopalatine foramen. The therapeutic element can include an energy delivery element configured to therapeutically modulate postganglionic parasympathetic nerves at microforamina of a palatine bone of the human patient for the treatment of rhinitis or other indications. In other embodiments, the therapeutic element can be configured to therapeutically modulate nerves that innervate the frontal, ethmoidal, sphenoidal, and maxillary sinuses for the treatment of chronic sinusitis.

Provided herein is a multifunctional aesthetic system including a housing, an electromagnetic array situated in the housing and having one or more electromagnetic radiation (EMR) sources, a controller in electronic communication with the array to operate the one or more of the EMR sources to direct the EMR beam to a treatment area, and one or more sensors in electronic communication with the controller for providing feedback to the controller based on defined parameters to allow the controller to adjust at least one operating condition of the multifunctional system in response to the feedback.
