| 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 |
| 20110196205 | SURGICAL PORTAL LOCKING SYSTEM - A surgical portal apparatus includes a portal having an elongated portal member and defining a portal passage for reception of a surgical object, and a locking base. The locking base includes a flange segment defining a longitudinal axis and having a longitudinal opening for permitting reciprocal longitudinal passage of the portal member and a locking segment mounted to the flange segment. The flange segment is dimensioned and configured for positioning against body tissue. The locking segment is dimensioned to selectively engage the portal member and establish a secured relation therewith to selectively secure the portal at a predetermined longitudinal position with respect to the longitudinal axis of the locking base. The flange segment of the locking base may include an adhesive coating for adhesive engagement with the body tissue. | 08-11-2011 |
