Publication number: 20150201935Abstract: In various embodiments, a surgical stapling instrument can include a handle, a shaft extending from the handle, wherein the shaft defines an axis, and a disposable loading unit which is assembled to the shaft in a direction which is transverse to the shaft axis. Such a connection between the disposable loading unit and the shaft can prevent, or at least inhibit, the disposable loading unit from being unintentionally displaced proximally and/or distally relative to the shaft of the surgical instrument. The surgical stapling instrument and/or disposable loading unit can further include a threaded collar and/or detent assembly configured to hold the disposable loading unit in place. In various embodiments, a disposable loading unit can include a lockout feature which can prevent, or at least inhibit, an expended disposable loading unit from being reassembled to the elongated body of the surgical instrument.Type: ApplicationFiled: March 30, 2015Publication date: July 23, 2015Inventors: William B.

Patent number: 8714360Abstract: A device is operable to separate tissue particles. The device comprises a reservoir and an ultrasonic transducer. The reservoir is configured to receive tissue particles in a fluid. The ultrasonic transducer is operable to emit ultrasonic energy toward tissue particles in the reservoir. Control circuitry is configured to drive the ultrasonic transducer at parameters selected to provide movement of tissue particles in the first reservoir based on the size of the tissue particles. The ultrasonic transducer may thus drive the tissue particles toward respective outlets or at particular times based on their particle size. An electrically driven screen may be used to separate tissue particles from liquid. An ultrasonic mincing device may be used to mince tissue particles whose size exceeds a predetermined size range.Type: GrantFiled: May 12, 2010Date of Patent: May 6, 2014Assignee: Ethicon Endo-Surgery, Inc.Inventors: Jeffrey S.

Patent number: 8568446Abstract: A surgical device comprises a housing, a plurality of media reservoirs, an end effector, and a pumping device. Each media reservoir is configured to receive at least one component of a tissue repair composition. The end effector is configured for insertion into a lumen to deliver a tissue repair composition into that lumen. The end effector has at least one fluid conduit and at least one orifice in communication with the fluid conduit. The pumping device is operable to urge a tissue repair composition comprising at least a portion of the contents of the plurality of media reservoirs through the fluid conduit of the end effector such that the tissue repair composition is expelled from the at least one orifice. The media reservoirs may contain medical fluid components such as viable cells and scaffold material to repair a fistula or address some other condition in a patient.Type: GrantFiled: May 13, 2010Date of Patent: October 29, 2013Assignee: Ethicon Endo-Surgery, Inc.Inventors: Takashi Kurokawa, Christopher W.
