The protrusion defines a cross-section that decreases progressively in width in the dimension D1 along the protrusion length distally from the base of the protrusion toward the distal tip of the protrusion.

Abstract: A device for treating a tissue includes a capsule extending longitudinally from a proximal end to a distal end and including a channel extending therethrough, clip arms, proximal ends of which are slidably received within the channel of the capsule so that the clip arms are movable between an open configuration, in which distal ends of the clip arms extend distally past the distal end of the capsule to be separated from one another, and a closed configuration, in which the clip arms are restrained via an interior surface of the capsule so that distal ends of the clips arms are drawn toward one another, and a reinforcement element coupled to the clip arms, the reinforcement element preventing deflection of the clip arms when engaging a target tissue.

Abstract: Devices, systems, and methods of the present disclosure are directed to efficient and accurate removal of tissue from a three-dimensional anatomic structure, such as a breast, of a patient. For example, a cup can be positioned on the patient's breast to conform the breast (e.g. via suction) to a known three-dimensional contour, and a cutting tip can be moved along the three-dimensional contour at one or more predetermined distances from at least one surface of the cup. The cutting tip can remove tissue along the three-dimensional contour to form a skin envelope. As compared to a manual process performed by a surgeon, formation of the envelope through controlled movement of the cutting tip along the three-dimensional contour can improve control over dimensions of the envelope, thus, facilitating achievement of consistent outcomes by reducing the likelihood of complications associated with an envelope that is too thick, too thin, or uneven.

Abstract: An expandable medical sheath can include a sheath body having a lumen that extends between proximal and distal ends of the sheath. The sheath can have first and second members where the first member has a different elastic modulus than the second member such that one provides elasticity to the sheath and the other provides column strength. The first and second members can be coupled together in alternating sections to form the tubular sheath or the stiffer members can be embedded in the elastic member along all or a portion of the longitudinal length of the sheath. The sheath can automatically move to an expanded state to allow a larger diameter medical device to pass through the lumen, and once through the sheath can automatically return to its initial diameter.

Abstract: A surgical appliance includes an elongate barrel having effector jaws mounted to a carrier secured to the distal end of the barrel. A handle includes a grip for opening and closing the effector jaws, a knob for articulating the carrier, a knob for rotating the barrel and a safety mechanism for automatically preventing inadvertent actuation of the grip. Each jaw pivots about a pin and is actuated by a rod which is engaged by the grip.

When the lever is released, the latch automatically returns to the blocking position. A toggle arm fixed to a cam shaft can be rotated such that a cam moves the latch to the disengaged position for repeated grip actuation.

Abstract: An instrument comprises a handpiece, a boss member, a cylindraceous cam body, a linearly movable member, a cam follower, and a braking member. The cam body is rotatably supported in the handpiece and includes an exterior cam feature. The cam follower couples the linearly movable member with the cam feature of the cam body.

The braking member extends about at least a portion of the exterior of the cam body and is positioned to progressively engage the boss member as the cam body rotates within the handpiece. The braking member and the boss member thus cooperate to provide gradual braking of the cam body. The instrument is operable to deploy a pressure equalization tube in the tympanic membrane of a patient.
