20090177212 | CLOSURE DEVICE AND METHODS FOR MAKING AND USING THEM - A clip for engaging tissue includes a generally annular-shaped body defining a plane and disposed about a central axis extending normal to the plane. The body includes alternating inner and outer curved regions, defining a zigzag pattern about a periphery of the clip. The body is biased towards a planar configuration lying in the plane and deflectable towards a transverse configuration extending out of the plane. Tines extend from the inner curved regions, the tines being oriented towards the central axis in the planar configuration, and parallel to the central axis in the transverse configuration. The tines may include primary tines and secondary tines that are shorter than the primary tines. The primary tines may be disposed on opposing inner curved regions and oriented towards one another such that they overlap in the planar configuration. | 07-09-2009 |
20090177213 | Methods For Manufacturing A Clip And Clip - The present invention relates to a method of making clips which can be used to engage body tissue for the purpose of closing wounds. Such clips are generally annular in shape and have radially inwardly extending tines. The present invention first forms a precursor which, in one embodiment, has the tines extending radially outwardly from the annular body and then forms the clip by inverting the precursor such that the tines extend radially inwardly. In an alternate embodiment, the precursor is formed with an over-sized lateral dimension and then compressed inwardly to bring the tines closer together and to reduce the lateral dimension of the precursor. It is preferred to manufacture such clips from a superelastic alloy such as nickel-titanium, in which case the inverted or compressed precursor must be heated and quenched to heat set the clip in its final shape. | 07-09-2009 |

The primary tines may overlap the body and may be of different lengths. | 06-16-2011 |
20110166584 | CLIP APPLIER AND METHODS OF USE - An apparatus for delivering a closure element into an opening formed in a blood vessel or other body lumen and methods for manufacturing and using same. The apparatus is configured to retain the closure element such that the closure element is disposed substantially within the apparatus. The apparatus also can engage, and position the closure element substantially adjacent to, the blood vessel wall adjacent to the opening. During deployment of the closure element, the apparatus expands the closure element beyond a natural cross-section of the closure element such that the closure element, when deployed, is configured to engage a significant amount of the blood vessel wall and/or tissue. Engaging the blood vessel wall and/or tissue, the closure element is further configured to return to the natural cross-section, thereby drawing the engaged blood vessel wall and/or tissue substantially closed and/or sealed, such that hemostasis within the opening is enhanced. | 07-07-2011 |
20110230897 | 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 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 |
