A surgical stapler includes a first elongate member, a second elongate member, a clamp member, and a firing assembly. The first elongate member includes a distal portion that supports an anvil surface that includes a plurality of staple forming pockets. The second elongate member includes a distal portion that is configured to receive a staple cartridge. The clamp member is operable to releasably clamp the first elongate member against the second elongate member. The firing assembly is translatable from a first longitudinal position to a second longitudinal position to fire the staple cartridge. The firing assembly includes a slider and an actuator. The slider includes a first coupling feature. The actuator is configured to be selectively actuated by a user. The actuator includes a second coupling feature that is configured to generally surround the first coupling feature of the slider when the actuator moves relative to the slider.

A medical device including a handle and a flexible member controlled by the handle, the handle including one or more knobs, each of the one or more knobs having a plurality of protrusions spaced circumferentially from one another, wherein the medical device comprises one or more grip-enhancing features configured to be removably coupled to the one or more knobs.

A surgical instrument includes a first lever element and a second lever element interconnected by a lever element hinge. Each lever element includes a grip portion and a jaw portion. A first spring portion and a second spring portion are proximally connected to the grip portions. A proximal free end of the first spring portion is coupled to a proximal free end of the second spring portion by a hinged joint. The hinged joint includes a hinge pin and at least one bearing eye. The at least one bearing eye forms a continuous longitudinal slit for radial insertion of the hinge pin. The slit extends diagonally relative to the axis of the at least one bearing eye so that at least one spring portion has to be twisted during radial insertion of the hinge pin into the at least one bearing eye.

A surgical instrument including a trigger configured to be actuated by a proximally directed force and by a distally directed force. The trigger may include a proximal trigger portion having a first length and a distal trigger hook comprising a distal portion having a second length. The second length may be less than the first length. The distal trigger hook may be coupled to the proximal trigger portion.

A portable device and method of supplying power to the portable device may provide a sterile environment that may protect the health and safety of patients on whom the device is employed. The portable device may be charged inside of the sterile environment. The portable device may be charged using at least one chargeable battery that may be arranged internal and/or external to a portion of the portable device, or internal and/or external to the portable device. A power supply may be connected to the at least one chargeable battery and power the portable device for use. The portable device may be charged up to 100% and/or or fully charged prior to opening the sterile environment.

One embodiment of the present invention relates to an electrosurgical handpiece that has a first main body and a second main body. A squeezable handle connects to and across the first main body and the second main body such that, when the handle is unsqueezed, the first main body and the second main body assume a first position relative to one another. When the handle is squeezed, the first main body and the second main body assumes a second position relative to one another. An active electrosurgical electrode is slidingly mounted within the second main body and extends from the second end. A spacer is positioned around and in sliding engagement with the smaller diameter region of the first main body.

Apparatus and methods are provided for treating a tissue opening, for example a trocar opening used in a minimally invasive surgical procedure. In a tissue closure device, a finger guard or shield can be used, handle or holding area or areas can be used, and positioning indicators can be used. A resiliently flexible target material can also be used for reliably holding a suture during the procedure. The resiliently flexible target material may be included as part of a removable mating component for use with a movable wing. Introducers can be used having a suture holder, an alignment indicator and insertion limits.

An invasive medical device assembly includes an invasive medical device and a hub housing configured to surround a portion of the invasive medical device. The invasive medical device may be a needle or other invasive medical device, and the hub housing may be configured to surround a hub of the invasive medical device. In one aspect, the invasive medical device may include a transducer. The hub housing can include at least one integrated circuit embedded therein that is configured to contact the external surface of the needle to electrically connect the transducer to a power source. The hub housing can be configured to provide an ergonomic handle for a user.

A surgical stapler includes first and second elongate members, a clamp member, and a firing assembly. The second elongate member is configured to receive a staple cartridge. The clamp member is operable to releasably clamp the first elongate member against the second elongate member. The firing assembly is translatable to fire the staple cartridge. The firing assembly includes a slider and an actuator configured to be selectively actuated by a user. The slider includes inner and outer engagement features. The actuator includes inner and outer engagement features. The inner engagement feature of the actuator is configured to engage with the inner engagement feature of the slider at a first interface when the actuator moves relative to the slider. The outer engagement feature of the actuator is configured to engage the outer engagement feature of the slider at a second interface when the actuator moves relative to the slider.

A tool useful for deploying a flip anchor connected to a cable includes a housing with a first end and a second end; and a guiding tube having a bore therethrough. The guiding tube has a proximal end releasably connected to the first end of said housing, and a distal end configured to hold said flip anchor. The housing includes a mechanism having a low resistance surface and a slider having a high friction surface facing the low resistance surface, where the slider is movable between a) a clamping position configured to clamp the cable between the low resistance surface and the high friction surface; and b) a release position configured to allow the cable to move freely on the low resistance surface. A safety button on said housing is movable between an elevated position where the safety button holds the slider in said first position, and a depressed position where the safety button releases the slider, allowing it to enter the second position. The slider is configured to move the cable distally upon movement from the clamping position to the release position, deploying the flip anchor from the guiding tube.
