Abstract: A method of applying a buttress to a surgical stapler end effector comprises positioning a buttress assembly between an anvil and a staple cartridge of the end effector. The buttress assembly comprises a buttress body and an adhesive material. The adhesive material faces either an underside of the anvil or a deck of the staple cartridge. The anvil is in an open position relative to the staple cartridge during the act of positioning the buttress assembly between the anvil and the staple cartridge. The method further comprises moving the anvil toward the staple cartridge then moving the anvil back to the open position. The buttress assembly is adhered to the underside of the anvil or the deck of the staple cartridge via the adhesive material with the anvil moved back to the open position. The adhesive material comprises a bioabsorbable polymer.

Abstract: Systems, devices, and methods for controlling cooperative surgical instruments with variable surgical site access trajectories are provided. Various aspects of the present disclosure provide for coordinated operation of surgical instruments accessing a common surgical site from different approach and/or separate body cavities to achieve a common surgical purpose. For example, various methods, devices, and systems disclosed herein can enable the coordinated treatment of tissue by disparate minimally invasive surgical systems that approach the tissue from varying anatomical spaces and must operate differently, but in concert with one another, to effect a desired surgical treatment.

Abstract: A device for and method of delivering a therapeutic fluid to the oral cavity of a user. The device includes a source of pressurized therapeutic fluid and a mouthpiece. The mouthpiece has a posterior facing end, and a body having a first surface for enabling the user's lips to seal the oral cavity from an external environment when the mouthpiece is received in the oral cavity. The mouthpiece comprises an inlet passageway and an outlet passageway extending through the body and in fluid communication with the posterior facing end, wherein the inlet passageway delivers a therapeutic fluid under pressure to the oral cavity and the outlet passageway enables egress of the therapeutic fluid from the oral cavity. The device can also include a reservoir for receiving saliva generated by the user that may be recirculated along with the therapeutic fluid to the oral cavity.

Abstract: In general, devices, systems, and methods for multi-source imaging are provided. In one embodiment, a surgical system is provided that includes a first imaging device configured to gather first images for visualization of a surgical target, a second imaging device configured to gather second images that enhance the visualization of the surgical target, and a controller configured to cause a display device to show a single view of the surgical target that is a cooperation of the first and second images. The first imaging device has a different point of view of the surgical site than the second imaging device.

Abstract: Systems, devices, and methods for controlling cooperative surgical instruments are provided. Various aspects of the present disclosure provide for coordinated operation of surgical instruments accessing various surgical sites from different or shared surgical approaches to achieve a common or cooperative surgical purpose. For example, various methods, devices, and systems disclosed herein can enable the coordinated treatment of tissue by disparate minimally invasive surgical systems that approach the tissue from varying anatomical spaces and must operate differently, but in concert with, one another to effect a desired surgical treatment.

Abstract: A staple cartridge assembly for use with a surgical stapling instrument includes a staple cartridge including a plurality of staples and a cartridge deck. The staple cartridge assembly also includes a compressible adjunct positionable against the cartridge deck, wherein the staples are deployable into tissue captured against the compressible adjunct, and wherein the compressible adjunct comprises a first biocompatible layer comprising a first portion, a second biocompatible layer comprising a second portion, and crossed spacer fibers extending between the first portion and the second portion.

Abstract: In general, devices, systems, and methods for fiducial identification and tracking are provided. In one embodiment, a surgical system includes a surgical device having a distal portion configured to be advanced into a body of a patient during performance of a surgical procedure, and a fiducial marker on an exterior of the distal portion of the surgical device.

Abstract: A surgical instrument. The surgical instrument includes an elongated channel configured to support a staple cartridge, an anvil pivotably connected to the elongated channel, a knife mechanically coupled to the staple cartridge, an electric motor and a control circuit electrically connected to the electric motor. The control circuit is configured to change a firing motion of the surgical instrument based on a combination of events.

Abstract: A valve assembly includes a valve having a head and a stem. The head is configured to seal against a valve seat. The stem has a distal end. A first piston radially extends from the stem of the valve and is enclosed within a housing. A second piston is fixed to the distal end of the stem and seals against the housing. A first chamber is defined by the first piston, second piston and the housing and receives a compressed gas and maintains a desired gas pressure. A spring device is disposed intermediate the first piston and the housing. During normal operation of the engine, the gas pressure within the first chamber seals the head of the valve against the valve seat with the spring device in a compressed arrangement and wherein during periods of insufficient gas pressure the spring device biases the valve to seal against the valve seat.
