A surgical instrument can comprise a channel configured to support a staple cartridge and, in addition, an anvil pivotable between open and closed positions relative to the channel. The surgical instrument can further comprise a cutting member configured to incise tissue positioned captured between the staple cartridge and the anvil and, in addition, means for stopping the cutting member prior to a distal end datum, wherein the distal end datum can be defined by the distal-most staple cavity in the staple cartridge. In such embodiments, the incision within the tissue may not extend beyond the portion of the tissue that has been stapled.

Surgical stapling instrument with an articulatable end effector

A surgical instrument including a handle assembly, a first endoscopic portion, a motor, and a first end effector is disclosed. The first endoscopic portion is selectively connectable to a distal portion of the handle assembly and defines a longitudinal axis. The first endoscopic portion includes a housing adjacent its proximal portion and includes an actuation member. The motor is disposed in mechanical cooperation with the housing of the first endoscopic portion and is operatively connected to the actuation member for moving the actuation member substantially along the longitudinal axis. The first end effector is selectively connectable to a distal portion of the first endoscopic portion and is configured to perform a first stapling function.

Powered surgical instrument

A surgical cutting and fastening instrument is disclosed. According to various embodiments, the instrument includes an end effector comprising an elongate channel, a clamping member pivotably connected to the channel, and a moveable cutting instrument for traversing the channel to cut an object clamped in the end effector by the clamping member when the clamping member is in a clamped position. The instrument may also comprise a main drive shaft assembly for actuating the cutting instrument in the end effector, a gear drive train connected to the main drive shaft assembly, and a motor for actuating the gear drive train. The instrument may also includes a closure trigger and a firing trigger, separate from the closure trigger, for actuating the motor when the firing trigger is retracted. Also, the instrument may comprise a mechanical closure system connected to the closure trigger and to the clamping member for causing the clamping member to pivot to the clamped position when the closure trigger is retracted.

Motor-driven surgical cutting and fastening instrument with tactile position feedback

A motor-driven surgical cutting and fastening instrument that comprises an end effector, an electric motor, and a motor control circuit. The motor control circuit is for monitoring a parameter of the electric motor that is indicative of movement of a moveable member of the end effector, and for adjustably controlling the electric motor based on the monitored parameter to thereby adjustably control movement of the moveable member of the end effector during forward rotation of the electric motor.

Motor-driven surgical cutting instrument

A device and method for ablating tissue is disclosed comprising the steps of acquiring an anatomical image of a patient, correlating the image to the patient, guiding an ablating member within the patient while tracking the position of the ablating member in the patient, positioning the ablating member in a desired position to ablate tissue, emitting ablating energy from the ablating member to form an ablated tissue area and removing the ablating member from the patient.

Methods of using high intensity focused ultrasound to form an ablated tissue area containing a plurality of lesions

A device and method for valve replacement or valve repair is disclosed comprising the steps of acquiring an anatomical image of a patient, correlating the image to the patient, guiding a valve replacement delivery member or a valve repair delivery member within the patient while tracking the position of the delivery member in the patient, positioning the valve replacement member or valve repair member in a desired position to place a valve or repair valve and removing the delivery member from the patient. In one aspect of the invention, a delivery system is provided for percutaneous delivery of a heart valve to a predetermined position in the heart of a patient, where the delivery system itself includes features that allow it to be accurately positioned in the heart. In another aspect of the invention, a delivery system is provided for percutaneous repair of a heart valve in the heart of a patient, where the repair system itself includes features that allow it to be accurately positioned in the heart. In another aspect of the invention, a method and device are provided that involve imaging a native root using an interoperative technique, then introducing a device that is easily visualized in a chosen imaging modality.

Method for guiding a medical device

A method of tonsil reduction by thermal ablation using high intensity focused ultrasound energy includes the steps of introducing an ultrasound emitting member in a patient's oral cavity, positioning the ultrasound emitting member adjacent an external surface of one of the patient's tonsils, emitting ultrasound energy from the ultrasound emitting member into the tissue of the one tonsil, focusing the ultrasound energy in the one tonsil, ablating the tissue of the one tonsil with the focused ultrasound energy to form an ablated tissue area in the one tonsil containing unablated tissue of the one tonsil and a plurality of lesions at which the tissue of the one tonsil is ablated, and withdrawing the ultrasound emitting member from the oral cavity. The ablated tissue area is surgically removed or is allowed to remain in the patient's body. The lesions may be absorbed by the patient's body and/or remain as altered tissue such that the tonsil is reduced in size to correspondingly increase the size of the patient's airway and/or is stiffened to resist vibration. The lesions can begin a predetermined distance beneath the external surface of the tonsil such that the mucosa is preserved. The lesions end at a predetermined depth so that muscular tissue is not damaged.

Methods of tonsil reduction using high intensity focused ultrasound to form an ablated tissue area containing a plurality of lesions

A method of thermal ablation using high intensity focused ultrasound energy includes the steps of positioning one or more ultrasound emitting members within a patient, emitting ultrasound energy from the one or more ultrasound emitting members, focusing the ultrasound energy, ablating with the focused ultrasound energy to form an ablated tissue area and removing the ultrasound emitting member.

Methods of using high intensity focused ultrasound to form an ablated tissue area

A focused ultrasound ablation device includes an ultrasound emitting member and a handle shaft having a distal end at which the ultrasound emitting member is disposed. The handle shaft is malleable to permit selective, manual shaping of the handle shaft to access a selected anatomical operative site from a remote location and/or to orient the ultrasound emitting member for contact with anatomical tissue at the selected operative site. A method of thermally ablating anatomical tissue includes the steps of manually shaping a malleable handle shaft to orient an active face of an ultrasound emitting member at a distal end of the shaft to contact anatomical tissue at a selected operative site, positioning the active face against the anatomical tissue at the operative site while a proximal end of the handle shaft is disposed at a remote location; emitting ultrasound energy from the ultrasound emitting member; focusing the ultrasound energy at one or more focusing zones within a target area in the tissue and located a predetermined distance in front of the active face and heating the tissue at the target area with the focused ultrasound energy to create a lesion.
