Disclosed herein are apparatuses, systems, kits, and methods for treating skin, such as skin tightening or for treating diseases, disorders, and conditions that would benefit from tissue area or volume reduction, skin restoration, skin tightening, skin lifting, and/or skin repositioning and/or for generally improving skin function or appearance (e.g., the removal of unwanted skin features or irregularities such as sebaceous glands, sweat glands, hair follicles, necrosis, and fibrosis). Such apparatuses, systems, kits, and methods comprise an apparatus having a handheld main body and a detachably attachable tip comprising one or more needles.

A method for attaching a drive rod to a knife includes: forming a knife having proximal and distal ends; forming an aperture within the proximal end of the knife, the aperture including a series of fins disposed therein; weaving a distal end of a knife rod through the series of fins in an alternating manner; and engaging a cap onto the distal end of the knife drive rod to secure the knife drive rod within the aperture of the knife.

Certain exemplary embodiments can provide an apparatus and method for generating at least one radiation. The exemplary apparatus and/or method can selectively kill and/or affect at least one bacteria. For example, a radiation source first arrangement can be provided which is configured to generate at least one radiation having one or more wavelengths provided in a range of about 190 nanometers (nm) to about 230 nm, and at least one second arrangement can be provided which is configured to prevent the at least one radiation from having any wavelength that is outside of the range.

Methods and devices for treating nasal airways are provided. Such devices and methods may improve airflow through an internal and/or external nasal valve, and comprise the use of mechanical re-shaping, energy application and other treatments to modify the shape, structure, and/or air flow characteristics of an internal nasal valve, an external nasal valve or other nasal airways.

Systems and methods for forming a lesion on an endocardial tissue of a patients heart involve placing an ablation assembly inside of the heart and adjacent to the endocardial tissue, and placing a guiding assembly outside of the heart. An ablation assembly includes an ablation element and a first attraction element, and a guiding assembly includes a second attraction element. First and second attraction elements can be attracted via magnetism. Techniques involve forming an ablation on the cardiac tissue of a patient's heart with an ablation element of the ablation assembly. Optionally, techniques may include moving the second attraction element of the guiding assembly relative to the patient's heart, so as to effect a corresponding movement of the ablation element of the ablation assembly.

An end effector assembly includes first and second jaw members movable between an open and closed position to grasp tissue therebetween. First and second proximal flanges extending proximally from the second jaw member and defining a space therebetween, a proximal flange extend proximally from a proximal portion of the first jaw member and define a cam slot. A cam driver operably is coupled to the proximal flange of the first jaw member to define a space between the cam driver and the proximal flange of the first jaw member. A cam bar is disposed within the space defined between the cam driver and the proximal flange of the first jaw member. The cam bar includes a cam pin configured to move within a cam slot of the cam driver to move the first jaw member relative to the second jaw member between the open position and the closed position.

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.

Methods and systems for modulating intraosseous nerves (e.g., nerves within bone) are provided. For example, the methods and systems described herein may be used to modulate (e.g., denervate, ablate) basivertebral nerves within vertebrae. The modulation of the basivertebral nerves may facilitate treatment of chronic back pain. The modulation may be performed by a neuromodulation device (e.g., an energy delivery device).

A skin imaging and diagnostic method and apparatus comprising, a frame, configured to circumscribe a target tissue on the skin of a patient. An electro-optics unit of the apparatus comprising: an illuminator assembly comprising illuminating elements, configured to provide illumination light on the target tissue; an imaging optics assembly; and an image sensor assembly, comprising an image sensor, wherein the imaging optics assembly is configured to collect backscattered said illumination light from the target tissue and focus the collected backscattered illumination light on the image sensor; and the image sensor is disposed to consequently sense an image of the target tissue. A controller configured to activate illuminating elements and to capture each image from the image sensor.

A structure of a surgical instrument configured for thermally cutting tissue. The structure includes a frame and a thermal cutting element. The frame includes a proximal flange portion and a distal body portion. The distal body portion includes a proximal section extending from the proximal flange portion, a distal section, and a center section extending between the proximal and distal sections. The distal body portion includes first and second distal body portion segments. The distal body portion segments are disposed a first distance apart from one another at the proximal section, a second distance apart from one another at the distal section, and a third distance apart from one another at the center section. The third distance is greater than the first and second distances. The thermal cutting element is disposed within the distal body portion of the frame and extends from the proximal section, through the center section, to the distal section.
