Another embodiment includes at least one grasping jaw, at least one delivery mechanism adapted to deliver surgical fasteners, the delivery mechanism being located in a proximity to or contained within the at least one grasping jaw, the surgical fasteners containing at least one shape-transforming material, at least one sensor, at least one chemical tissue sealant and at least one cutter. A method includes: grasping a body organ/tissue with at least one grasping jaw, adjusting a configuration of the grasping in response to a signal or a datum or an image, and releasing a surgical staple/fastener in response to the signal, datum or image.

Surgical fastener applying apparatus

A surgical fastener applying apparatus is provided including a cartridge half-section and an anvil half-section, the cartridge half-section and anvil half-section being relatively movable from an unclamped position to a clamped position; and a loading unit receivable in the cartridge half-section and having a plurality of staples and a plurality of staple pusher members. The cartridge half-section includes a frame; a member being longitudinally movable through the loading unit to interact with the plurality of staple pusher members to fire the staples; and a lockout mechanism arranged to block advancement of the member in a locked-out position of the lockout mechanism. In use, after loading of the loading unit in the surgical fastener applying apparatus and subsequent clamping of the cartridge and anvil half-sections, the lockout mechanism is moved to an unlocked position to allow advancement of the member.

Embodiments include a surgical device and a method. An embodiment of the surgical instrument includes at least one grasping jaw, the at least one grasping jaw being adapted to deliver surgical staples by a force generated from a force generator mechanism that is contained within the at least one grasping jaw or is in a proximity to the at least one grasping jaw. Another embodiment includes at least one grasping jaw, at least one actuation mechanism adapted to deliver surgical fasteners, the actuation mechanism being located in a proximity to or contained within the at least one grasping jaw, the surgical fasteners containing at least one shape-transforming material, at least one sensor, at least one chemical tissue sealant and at least one cutter. A method includes: grasping a body organ/tissue with at least one grasping jaw, adjusting a configuration of the grasping in response to a signal or a datum or an image, and releasing a surgical staple/fastener in response to the signal, datum or image.

TISSUE ABLATION APPARATUS AND METHOD

A method and apparatus for carrying our thermal ablation of target tissue is disclosed. The apparatus includes an RF ablation device having a multi-electrode electrode assembly designed to be deployed in target tissue, defining a selected-volume tissue region to be ablated, and having infusion channels for infusing a liquid into the target tissue during the ablation process. A control unit in the apparatus is operably connected to an RF energy source, for controlling the RF power level supplied to the electrodes, and to an infusion device, for controlling the rate of infusion of a liquid through the device into the tissue. During both electrode deployment and tissue ablation, impedance and or temperature measurements made within the tissue are used to control the RF source and infusion device, for optimizing the time and extent of tissue ablation.

Tissue aperture securing and sealing apparatuses and related methods of use

Embodiments of the invention are directed to apparatuses for securing and sealing apertures in tissue and related methods of use. An exemplary apparatus for collapsing an aperture in a wall of tissue can include a base biased to collapse into a collapsed state from an expanded state. The apparatus can also include a plurality of collapsible fingers extending from the base, wherein the collapsible fingers can be configured to collapse about tissue adjacent to and defining the aperture so as to close the aperture in the wall of tissue.

Integrated receiver for continuous analyte sensor

A system is provided for monitoring glucose in a host, including a continuous glucose sensor that produces a data stream indicative of a host's glucose concentration and an integrated receiver that receives the data stream from the continuous glucose sensor and calibrates the data stream using a single point glucose monitor that is integral with the integrated receiver. The integrated receiver obtains a glucose value from the single point glucose monitor, calibrates the sensor data stream received from the continuous glucose sensor, and displays one or both of the single point glucose measurement values and the calibrated continuous glucose sensor values on the user interface.
