An implant unit delivery tool is provided. The implant delivery tool may include a body, a holder disposed at a distal end of the body and adapted to hold an implant unit, and an implant activator associated with the body, the implant activator configured to receive power from a power source. The implant activator may be configured to selectively and wirelessly transfer power from the power source to the implant unit during implantation of the implant unit into the body of a subject to cause modulation of at least one nerve in the body of the subject, and determine a degree of nerve modulation response resulting from the selective and wireless transfer of power from the power source to the implant unit claims.

Some embodiments are directed to a robotic manipulator interface for coupling a hinged surgical tool to a manipulator of a surgical robot, the interface including a first interface member to be coupled to the manipulator, and a second interface member to be coupled to the first interface member, the second interface member being arranged to mount the hinged surgical tool, wherein the first interface member includes a pinching mechanism for pinching the hinged surgical tool when the second interface member is coupled to the first interface member, wherein the pinching mechanism includes two movable protrusions protruding from a surface of the first interface member, the first interface member including a built-in actuating mechanism for moving the protrusions to each other to push two arms of the mounted hinged surgical tool towards each other so as to actuate the mounted hinged surgical tool through the sterile drape.

Conventional vasectomy techniques suffer from a number of disadvantages and potential complications, including, for example, a substantial risk for the development of hematomas, swelling, and post-surgical pain, a potential for spontaneous regeneration and undesired resumption of fertility, a need for a highly skilled surgical professional, as well as a long recovery period, accompanied by severe limitations on post-surgical activity. The present invention overcomes the disadvantages and deficiencies of the prior art by providing vasectomy instruments, kits, and methods that allow for a rapid, reliable, less invasive male sterilization procedure that may be readily, reliably and successfully performed by minimally skilled personnel around the world in a variety of medical settings.

Certain aspects are directed to an ophthalmic specialty instrument configured to allow patients to treat MGD and other dry eye conditions themselves which is easy to operate and more effective. The ophthalmic specialty instrument comprises a main body of two arms with a distal end and a proximal end; wherein the two arms are pivotably coupled to a common connection point at the proximal end and a pair of angled and slightly wedged pressure plates are attached to the distal end of the two arms; wherein an exfoliating member is also attached to the proximal end; and wherein the pressure plates are angled downwardly and outwardly from the longitudinal planes of the arms and have gentle radius of curvature that match the curvature of eyelids to facilitate a substantially 90° approaching angle to the eyelid margin as opposed to making contact with the eyelids tangentially.

Exemplary methods and devices can be provided for harvesting a plurality of small tissue pieces, e.g., having widths less than about 1 mm or 0.5 mm, using one or more hollow needles. A fluid can be flowed through a conduit past the proximal ends of the needles to facilitate removal of the tissue pieces from the needle lumens, and can maintain the tissue pieces in a controlled and protective liquid environment. A filter can be used to extract and collect the tissue pieces from the liquid, or the tissue pieces can be deposited directly onto a porous dressing. Such tissue pieces can be used as microscopic grafts, which can be applied directly to a wound site or provided on a substrate or dressing, or stored for later use. Such microscopic grafts can promote tissue regrowth and wound healing, or can be applied to a scaffold to grow new tissue.

A gastric tube for use in a bariatric surgical procedure includes an elongate tube and a movable component supported on an outer surface of the elongate tube. The elongate tube has a non-circular cross section along at least a portion of a length of the elongate tube. The movable component is movable between an unexpanded configuration and an expanded configuration. In the unexpanded configuration, the movable component is disposed in abutting engagement with the outer surface of the elongate tube. In the expanded configuration, the movable component bows outwardly from the outer surface of the elongate tube.
