20080312666 | CLIP APPLIER AND METHODS OF USE - An apparatus for delivering a closure element can include a splittable carrier tube and a splitter to split the tube. The carrier tube can have an outer surface retaining a closure element in a tubular configuration and can be split into radially-expandable flaps. A closure element has can have shape-memory body having a relaxed configuration with a planar-annular body defining a lumen with tines directed inwardly from the body. The clip can be held in a retaining configuration having a substantially asymmetrically-elongated tubular shape with a trapezoidal longitudinal cross-sectional profile and a proximal end having the tines being longitudinally directed with a first tine being more distally oriented compared to a substantially opposite second tine being more proximal, and retracting to a deploying configuration having a tubular shape with a rectangular longitudinal cross-sectional profile with the first tine being even with the second tine when being delivered. | 12-18-2008 |
20110071567 | ARTICULATING SUTURING AND DEVICE AND METHOD - Devices, systems, and methods for suturing of body lumens allow the suturing of vascular puncture sites located at the distal end of a percutaneous tissue tract. An elongated articulated foot near a distal end of a shaft is inserted through the penetration and actuated so that the foot extends along the lumenal axis. The foot carries suturing attachment cuffs, and needles are advanced from the shaft through the vessel wall outside of the penetration and into engagement with the needle cuffs after the foot has been drawn proximally up against the endothelial surface of the blood vessel. The cross-section of the shaft within the tissue tract can be minimized by laterally deflecting the needles as they leave the shaft, while tapered depressions within the foot can guide the advancing needles into engagement with the cuffs. The cuffs lockingly engage the needles and can be withdrawn proximally along the needle paths and through the tissue tract so as to form a loop of suture across the puncture. The articulating foot may be realigned with the shaft and withdrawn proximally through the tissue tract without dilating the tissue tract. | 03-24-2011 |
20110106104 | SNARED SUTURE TRIMMER - A suture trimmer having a shaft, a cutting member, an actuating device, and a snare. The shaft has a first end and a second end and bounds a bore extending from the first end toward the second end. The shaft has an opening formed in a side adjacent the first end. The cutting member is slidably disposed within the bore of the shaft and can be moved between a first position and a second position, such that when disposed in the second position the cutting member closes the opening formed in the side of the shaft. The actuating device is in communication with the cutting member and is operable to move the cutting member from the first position to the second position. The snare extends through the opening and out of the bore at the first end of the shaft. | 05-05-2011 |

A closure element can have a shape-memory body having a relaxed configuration with a planar-annular body defining a lumen with tines directed inwardly from the body. The clip can be held in a retaining configuration having a substantially asymmetrically-elongated tubular shape with a trapezoidal longitudinal cross-sectional profile and a proximal end having the tines being longitudinally directed with a first tine being more distally oriented compared to a substantially opposite second tine being more proximal, and retracting to a deploying configuration having a tubular shape with a rectangular longitudinal cross-sectional profile with the first tine being even with the second tine when being delivered. | 09-22-2011 |
20120245626 | METHODS OF USE OF A CLIP APPLIER - A method for closing an opening formed in a wall of a body lumen or body tissue can include positioning a splittable carrier tube adjacent to the opening, the carrier tube having a splittable distal end with an outer surface retaining a closure element in a substantially tubular configuration or having an asymmetrically-elongated tubular shape with a trapezoidal longitudinal cross-sectional profile. The method including splitting a distal end of the carrier tube with a splitter and deploying the closure element from the carrier flaps of the carrier tube and over the splitter to allow the closure element to engage at least a portion of the wall of the body lumen or the body tissue and substantially close the opening. | 09-27-2012 |
20130030451 | SUTURE TRIMMER - In accordance with the present invention there is provided a suture trimmer, the suture trimmer comprising a shaft having a proximal end and a distal end and an axis therebetween, the shaft having a groove formed in the side thereof, the groove in communication with an opening formed in the side of the shaft, the opening disposed proximal the distal end. The suture trimmer further including a cutting member slidably disposed within the shaft, and a suture retainer slidably disposed within the shaft. Wherein the suture trimmer in accordance with the present invention may be additionally utilized to position knots formed within a suture loop prior to trimming the free end(s) of the suture loop. | 01-31-2013 |

20140276906 | FEATURES TO IMPROVE AND SENSE TYMPANIC MEMBRANE APPOSITION BY TYMPANOSTOMY TUBE DELIVERY INSTRUMENT - A tympanostomy tube delivery device comprises a shaft assembly, a pressure equalization tube, and a sensor. The shaft assembly comprises a cannula and a pusher operable to translate relative to the cannula. The pressure equalization tube is positioned within the shaft assembly. The pusher is operable to drive the pressure equalization tube out of the shaft assembly. The sensor is operable to detect a physical parameter associated with engagement between the distal end of the shaft assembly and a tympanic membrane. A controller may activate a feedback device to inform an operator that the distal end of the shaft assembly has achieved suitable apposition with the tympanic membrane, based on information from the sensor. | 09-18-2014 |
20140277050 | TYMPANOSTOMY TUBE DELIVERY DEVICE WITH CUTTING DILATOR - A tympanostomy tube delivery device comprises a body, a cannula extending distally from the body, and a cylindraceous member disposed within the cannula. The cylindraceous member comprises a tubular portion and a plurality of leaves positioned at the distal end of the tubular portion. The leaves are movable between a collapsed position and an expanded position. The cylindraceous member is slidable relative to the cannula to selectively expose the leaves relative to the open distal end of the cannula. A first leaf of the plurality of leaves has a sharp distal point configured to pierce a tympanic membrane and a longitudinally extending sharp edge. The cylindraceous member may be used to create and dilate a myringotomy incision in a tympanic membrane. The tympanostomy tube delivery device may then be used to deploy a tympanostomy tube through the myringotomy incision. | 09-18-2014 |
