A stapler is provided. The stapler includes a handle assembly and a shaft extending distally from the handle assembly. A tool assembly is configured to selectively couple to the shaft and includes a cartridge assembly and an anvil assembly. The cartridge assembly includes a staple guide defining a tissue contacting surface. A resilient member operably positioned within the cartridge assembly is configured to bias the staple guide distally to provide a predetermined compressive force against tissue when the cartridge assembly and anvil are approximated toward one another.

Intravascular implant systems and methods of positioning and detaching implants are described. One such system carries an implant by retaining an engagement member in a position proximal to an aperture at a distal end of the delivery system. The engagement member is retained proximal to the aperture by an elongate member that is coupled to the implant. Once the implant is in a desired implant position, the elongate member is released from the engagement member, and the implant is allowed to move away from the delivery system.

A method for performing a surgical procedure within lungs of a patient. The method comprising the steps of providing a plurality of surgical instruments and providing a housing. Attaching a flexible, elongated shaft with distal and proximal ends to the housing. Engaging at least one working end to the distal end of the housing, the working end including a plurality of tubes disposed therein that define a corresponding plurality of working channels for housing a corresponding plurality of surgical instruments. Controlling an actuator to engage at least one of the corresponding plurality of surgical instruments, wherein rotation of the working end with respect to a longitudinal axis of the elongated shaft engages at least one of the plurality of surgical instrument with the actuator to deploy the at least one surgical instrument to the lung as needed during a surgical procedure.

A removable electrode assembly for use in combination with a forceps having opposing end effectors and a handle for effecting movement of the end effectors relative to one another. The electrode assembly includes a housing which is removably engageable with the forceps and a pair of electrodes which are attachable to a distal end of the housing. The electrodes are removably engageable with the end effectors of the forceps such that the electrodes reside in opposing relation relative to one another. The electrode assembly also includes a cover plate which is removably attachable to the housing and at least one stop member for controlling the distance between the opposing electrodes. The stop member is selectively engageable with the electrodes.


A surgical instrument is provided including a handle assembly, a shaft electrically coupled to the handle assembly and extending therefrom, an electrode assembly electrically coupled to the shaft for transmitting energy to tissue to treat tissue, and a chamber defined in the shaft and positioned proximal a distal end thereof and configured to selectively expand. The expansion of the chamber anchors the surgical instrument to the tissue.


A microwave antenna assembly is disclosed. The antenna assembly includes an elongated member defining a longitudinal axis and having proximal and distal ends. The antenna assembly also includes an outer conductor and an inner conductor each disposed within the elongated member and extending along the longitudinal axis. A portion of the inner conductor is deployable relative to the outer conductor such that the antenna assembly may transition from a first configuration to a second configuration. The antenna assembly also includes an expandable sheath at least partially disposed about a distal portion of the inner conductor and defining at one or more lumens configured to couple to a supply of dielectric material used to regulate the expansion of the expandable sheath.

A surgical staple cartridge including a set of staples arranged in a nested arrangement, comprising a first subset of staples for use in a first annular array having a first length of backspan and a second subset of staples for use in a second annular array having a backspan greater in length than first subset.


A laser surgery system (10) includes a source of laser energy (14), a controller (13) operatively coupled to the source of laser energy (14), and a laser surgical instrument. The laser surgical instrument comprises: a cladding (22,42) having a first refractive index; a fiber optic core (21,41) coaxially disposed within the cladding (22,42) and having a second refractive index that is higher than the first refractive in-dex, the fiber optic core (21,41) configured to be operatively engage with the source of laser energy (14) at a proximal end; a fiber optic tip (27,47) formed on a distal end of the fiber optic core (21,41) wherein the fiber optic tip (27,47) extends outwardly from the cladding (22,42); and a plurality of refracting surfaces (25,45) formed around the fiber optic tip (27,47), each refracting surface (25,45) formed at least at one angle relative to a longitudinal axis (A) of the fiber optic tip (27,47) and configured to disperse the laser energy in a radial pattern.
