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.

Snoring and sleep apnea are conditions associated with a narrowing of the airway. A device (10) and a method for piercing a soft tissue channel in the pharynx and an implant for insertion into this soft tissue channel are disclosed, with which these symptoms can be treated. The device according to the invention comprises a handle (12) and a blade (11) with a tip (16), which are connected to each other via an interface (13). In this process, a channel is pierced through the device (10), the shape of which is designed in connection with the shape of the implant in such a way that the narrowing of the airways is optimally treated.

Scalpel blades, scalpels, scalpel assemblies, and methods thereof can be configured to reduce or even eliminate occurrences of skin bridges from skin-nicking such as when expanding insertion sites for catheters. For example, a scalpel blade can include a blade edge and a back edge, which back edge can include a pair of guidewire clips configured to clip onto a guidewire. The blade edge can terminate with a blade tip at a distal end of the scalpel blade. The pair of guidewire clips can be configured to clip onto the guidewire with sufficient clearance for slidably guiding the scalpel blade along the guidewire when skin-nicking a patient's skin and fascia around an insertion site established by a percutaneous puncture. The scalpels and scalpel assemblies can include the example scalpel blade. The methods can include methods of using any of the scalpel blades, scalpels, or scalpel assemblies disclosed herein.

A saw blade includes a main body having a first surface, a second surface on an opposite side of the main body from the first surface, a proximal edge portion, a distal edge portion, and first and second side portions extending between the proximal and distal edge portions. The proximal edge portion is configured to be coupled to a rotatable hub such that the saw blade is held in a curved shape with the first surface defining an outer radius when the saw blade is coupled to the rotatable hub. The distal edge portion includes a plurality of cutting teeth, and the second surface includes a cutting structure configured such that a radius of an arc swept by the cutting structure when the saw blade is rotated is substantially equal to the outer radius of the first surface.

A scalpel handle includes a receiving member to receive a blade therethrough and a main portion coupled to the receiving member. The main portion has a number of indentations on both a first surface and a second surface thereof. The indentations are evenly spaced between one another and the number of indentations extends from a first end proximate the receiving member along a first length of the main portion across an entire width thereof. The first length is at least two-thirds of a second length of an entirety of the main portion. The width of the main portion is at least five times a maximum width of the receiving member. A thickness of the main portion is at least 2.5 times a maximum thickness of the receiving member. All outer surfaces of the main portion including the first surface and the second surface are convex in shape around edges thereof.

A system for harvesting a tendon graft is disclosed, including a retractor, a guide and a harvesting tool. The retractor is collapsible and upon release, becomes self-supporting to hold open an anatomic space developed in a patient above the tendon. A guide assembles with the retractor to orient a guide shaft along the retractor and thereby the anatomic space. The harvesting tool includes a working end with a blade edge for cutting into the tendon. The harvesting tool defines a contoured surface for engaging and translating along the guide shaft while assembled to the retractor. The guide shaft and contoured surface limit the trajectory and translation extent of the harvesting tool along and into the tendon.
