The clip applier of the present invention can bring up two ligating clips at the same time with the first jaw unit and the second jaw unit, whereas the two clamping positions of the blood vessel can be clamped with the ligating clips simultaneously by the clip applier of the present invention in a single step, and thus the operating steps can be simplified, and the time involved with the surgical operation can be shortened.12-16-2010
20130123807Through the Scope Tension Member Release Clip - An apparatus for deployment of a hemostatic clip includes a clip assembly releasably coupled to a distal portion of a shaft, wherein the clip assembly includes a capsule releasably coupled to the shaft, clip arms slidably received within the capsule and cooperating with the capsule to provide a first user feedback indicating a decision configuration of the clip assembly and a yoke slidably received within the capsule, the yoke including proximal and distal portions releasably and rotatably connected to one another via a first control wire, a distal end of the distal portion being connected to proximal ends of the clip arms. A second control wire extends from the handle assembly and is coupled to a proximal end of the second portion to move the clip assembly between open and closed configurations.05-16-2013
20130123808Heart-Shaped PFO Closure Device - Patent foramen ovale (PFO) closure clip include two closure members, which may be heart shaped, joined by at least two spaced central connecting members. Each of the at least two spaced central connecting members is attached to each closure member at a location on the periphery of the closure member. The connecting member may be generally square shaped or include other shapes. The clips of the present invention may be formed of various materials, including metals, nonmetallic materials, bioresorbable polymers, spring steel, shape memory materials, bioresorbable shape memory polymers, or combinations thereof. The clips can take various forms depending, in part, upon the distribution of force required to close a given PFO. At least one of the closure members can include a tissue scaffold.05-16-2013
20110313432APPLICATOR FOR SURGICAL CLIPS - A hand-operable surgical clip applicator (12-22-2011
20130190777CLIP DEPLOYMENT TOOL AND ASSOCIATED METHODS - A laparoscopic device comprising: (a) a housing operatively coupled to a first control and a second control; (b) an end effector operatively coupled to the first control, the end effector comprising a first component and a second component selectively repositionable with respect to one another within an X-Y plane, the end effector also including a third component selectively repositionable with respect to the second component within an Y-Z plane; (c) a laparoscopic conduit extending between the housing and the end effector; and, (d) an occlusion clip deployment device operatively coupled to the end effector and the second control.07-25-2013
20130190778CLIP 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 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.07-25-2013
