| 20090242611 | Surgical Stapling Instrument - An end effector for a surgical instrument includes a cartridge assembly housing a plurality of fasteners, an anvil assembly operatively connected to the cartridge assembly, and a transducer operably connected to at least one of the cartridge assembly and the anvil assembly. The anvil assembly and the cartridge assembly are movable between open and closed positions. The transducer is adapted to effect vibrations along at least one of the anvil assembly and the cartridge assembly. The vibrations reduce the friction on the end effector, thereby reducing the force necessary to fire the end effector. | 10-01-2009 |
| 20090318938 | Spring-Type Suture Securing Device - A suture securing device includes a body with a distal end portion defining a suture receiving opening; a shaft and the body being assembled for relative reciprocal motion between a first position and a second position; and a tension coil spring operably attached to the body and operably attached adjacent a distal end portion of the shaft and disposed adjacent a suture receiving opening, When the body and shaft are in the first position, the tension coil spring is in a rest position, and when the body and/or the shaft are in the second position, the tension coil spring is in a tensioned position to form at least one gap therebetween to enable receipt of at least a portion of at least one suture. | 12-24-2009 |
| 20100234806 | PORT FIXATION USING EXPANDABLE THREADS - The present disclosure describes a surgical access apparatus including an access member with a longitudinal opening defining an internal dimension suitable for removable receipt of a surgical instrument. The access member has a thread mounted thereon that is movable between a first condition and a second condition. When the thread is in the first condition, the access member defines a first outer dimension that allows for positioning of the access member within a tissue tract, and when the thread is in the second condition, the access member defines a second, larger outer dimension to facilitate anchoring of the access member within the tissue tract. As the thread moves between the first and second conditions, the internal dimension of the longitudinal opening extending through the access member remains substantially constant. | 09-16-2010 |
| 20100249810 | SUTURE MANAGEMENT SYSTEM FOR SURGICAL PORTAL APPARATUS INCLUDING SLOTTED RING - A surgical portal apparatus for use in surgical procedures incorporating at least one suture is provided. The surgical portal apparatus includes a portal member defining a longitudinal axis and having a longitudinal opening therethrough for receiving a surgical object, and a suture retaining insert configured to be selectively received in the portal member. The suture retaining insert may include a base and a plurality of spaced projections extending radially outward from the base, the projections being radially spaced whereby adjacent projections define a suture receiving passage adapted to accommodate a suture. | 09-30-2010 |
| 20100268030 | Self-Steering Endoscopic Device - An endoscopic device including mechanisms to facilitate insertion of the device is disclosed. The device includes a sensing assembly configured for determining the position of the distal end of the device relative to a lumen. The device may further including a steering mechanism configured to direct the distal end of the device. A controller may be operably connected to the sensing assembly and the steering mechanism. The controller may be incorporated into the endoscopic device. Alternately, the controller may be positioned remote of the endoscopic device. | 10-21-2010 |
| 20100286483 | SURGICAL PORTAL DEVICE - A surgical portal device comprising a body portion and at least one securing member is disclosed. The body portion defines a longitudinal axis and includes a proximal end, a distal end, and a lumen configured to allow a surgical instrument to pass therethrough. The at least one securing member is disposed in mechanical cooperation with the body portion and is radially expandable with respect to the body portion between an initial position and an expanded position. The at least one securing member includes a hydrophilic material and is configured to radially expand in response to contact with moisture. | 11-11-2010 |
| 20110082476 | Handle Assembly for Endoscopic Suturing Device - A handle assembly for operating an articulatable surgical instrument is provided and includes a housing; an actuation shaft translatably and rotatably supported in the housing; a first trigger supported on the housing and connected to the actuation shaft, the first trigger being configured to translate the actuation shaft to operate a first function of the surgical instrument; a second trigger supported on the housing and connected to the actuation shaft, the second trigger being configured to rotate the actuation shaft to operate a second function of the surgical instrument; and a second-trigger release supported in the housing, the second-trigger release having a first position blocking actuation of the second trigger and a second position permitting actuation of the second trigger, where the second-trigger release is actuated from the first position to the second position upon and complete actuation of the first trigger. | 04-07-2011 |

| 20090182354 | Surgical Stapling Apparatus - A surgical device includes a loading unit having proximal and distal portions. The proximal portion of the loading unit is configured to be attached to an actuation apparatus. The surgical device further includes a flexible shaft interconnecting the proximal portion and the distal portion of the loading unit. Additionally, the surgical device has a tool assembly disposed in mechanical cooperation with the distal portion of the loading unit. The tool assembly is configured to articulate upon activation of the actuation apparatus. In a further embodiment, the surgical device includes a guiding member operatively connected to the tool assembly. The guiding member has a body and a bore extending through the body. The bore slidably receives a suture | 07-16-2009 |
| 20090320861 | Methods For The Placement Of Sutures In Tissue - A method for the placement of sutures in tissue prior to forming an opening in the tissue, the sutures for use in closing the opening, the method includes the steps of passing a first length of suture through a first portion of a tissue in a first direction relative to a target area to be incised, passing the first length of suture through a second portion of the tissue in the first direction, passing a second length of suture through a third portion of the tissue in a second direction relative to the target area to be incised, passing the second length of suture through a fourth portion of the tissue in the second direction, performing a surgical procedure including forming the opening in the tissue, and applying tension to the first length of suture and the second length of suture to close the opening in the tissue. | 12-31-2009 |
| 20100076433 | Endoscopic Vessel Sealer and Divider Having a Flexible Articulating Shaft - An electrosurgical instrument for treating tissue includes a housing having a flexible shaft extending therefrom having an axis A-A defined therethrough. The flexible shaft has first and second jaw members attached at a distal end thereof and each jaw member includes an electrically conductive tissue contacting surface adapted to connect to a source of electrosurgical energy such that the electrically conductive tissue contacting surfaces are capable of conducting electrosurgical energy through tissue held therebetween. A drive assembly is disposed in the housing and has a first actuator operably coupled to a drive rod for reciprocation thereof and a second actuator operably coupled to the drive rod for rotation thereof. A knife is operably coupled to a distal end of the drive rod. Actuation of the first actuator moves the jaw members relative to one another for engaging tissue and actuation of the second actuator rotates the drive rod about the axis A-A to translate the knife to cut tissue disposed between the jaw members. | 03-25-2010 |
