| 20110313452 | 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. | 12-22-2011 |
| 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 |
| 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 |
| 20110144668 | CLOSURE DEVICE - 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 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. The primary tines are configured such that they are offset from the axes of symmetry of the curved regions from which they extend and are connected to the curved regions by curved or linear regions or are connected directly to the curved regions. The primary tines may overlap the body and may be of different lengths. | 06-16-2011 |

| 20110106148 | CLOSURE SYSTEM AND METHODS OF USE - A closure system and methods of use are provided for use in sealing an opening in a body tissue, such as a vascular puncture site. A method of closing the opening in the body tissue can be performed with the closure system having a closure clip. The method can include positioning the closure clip in a first closure clip position adjacent to the opening in the body tissue such that a plurality of spikes of the closure clip are inserted into the tissue at a location outward from a central axis of the opening. Subsequently, the closure clip can be positioned in a second closure clip position such that the plurality of spikes are pulled inward toward the central axis of the opening so as to pull the tissue between the opening and each of the spikes together and close the opening. | 05-05-2011 |
| 20110071565 | APPARATUS AND METHODS FOR PROVIDING TACTILE FEEDBACK WHILE DELIVERING A CLOSURE DEVICE - An apparatus for sealing a passage through tissue includes a tubular member, a plug, and a locator member. The plug is disposed on a distal end of the tubular member and includes an external thread. The locator member is inserted into a lumen of the tubular member until a distal portion is disposed beyond the plug. The distal portion includes a helically wound wire and a tether coupled to the wire that is movable for causing the wire to buckle. To seal a passage communicating with a blood vessel, the distal portion of the locator member is inserted into the passage, and the plug is threaded into the passage until the distal portion extends into the vessel. The tether is pulled to buckle the wire, and the plug is unthreaded until the buckled wire contacts a wall of the vessel, whereupon the plug is released to seal the passage. | 03-24-2011 |
| 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 invention comprises an integrated vascular device having a sheath with a closure component and puncture sealant. The closure component is disposed on and advanceable over the exterior of the sheath and may comprise any of a variety of apparatus suited for closing a vascular puncture. Once the closure component has been actuated to close the puncture, sealant is introduced to seal the puncture. The sheath and closure component are then removed from the patient. | 09-11-2008 |
