Abstract
A medical device may include an outer assembly having a first shaft, a first lumen extending through the first shaft, and an atraumatic first tip removably coupled to a distal end of the first shaft; an inner assembly configured to extend through the first lumen of the outer assembly, the inner assembly including a second shaft, a second lumen extending through the second shaft, and a second tip removably coupled to a distal end of the second shaft, the second tip being configured to pierce tissue; and a plug assembly configured to extend through the second lumen of the inner assembly, the plug assembly including a third shaft and a plug removably coupled to a distal end of the third shaft.
Claims29
A medical device, comprising:
- an outer assembly having a first shaft, a first lumen extending through the first shaft, and an atraumatic first tip removably coupled to a distal end of the first shaft;
- an inner assembly configured to extend through the first lumen of the outer assembly, the inner assembly including a second shaft, a second lumen extending through the second shaft, and a second tip removably coupled to a distal end of the second shaft, the second tip being configured to pierce tissue;
- and
- a plug assembly configured to extend through the second lumen of the inner assembly, the plug assembly including a third shaft and a plug removably coupled to a distal end of the third shaft.
A method, comprising:
- advancing an inner assembly through a blood vessel wall of a subject, the inner assembly including a first beveled tip removably coupled to a first shaft, the first beveled tip defining an opening and including a flange at a first end thereof and a tip end at a second end thereof, wherein the advancing the inner assembly includes advancing the inner assembly in a first bevel configuration in which the tip end is positioned toward the blood vessel wall and the flange is positioned away from the blood vessel wall;
- proximally retracting the inner assembly such that the flange abuts an interior surface of the blood vessel wall;
- advancing an outer assembly distally toward the blood vessel wall, wherein the outer assembly includes a second beveled tip removeably coupled to a second shaft, wherein the advancing the outer assembly includes advancing the outer assembly until the second beveled tip contacts a skin of the subject or an exterior surface of the blood vessel wall;
- coupling the first beveled tip to the second beveled tip so as to clamp tissue therebetween;
- delivering a plug assembly through the inner assembly until a plug of the plug assembly engages the first beveled tip, thereby closing the opening, the plug assembly including the plug removably coupled to a plug shaft;
- and
- removing the first shaft from the first beveled tip, the second shaft from the second beveled tip, and the plug shaft from the plug.
A method, comprising:
- advancing an inner assembly through a target tissue wall of a subject, the inner assembly including a first beveled tip removably coupled to a first shaft, the first beveled tip defining an opening and including a flange at a first end thereof and a tip end at a second end thereof, wherein the advancing the inner assembly includes advancing the inner assembly in a first bevel configuration in which the tip end is positioned so as to contact the target tissue wall before the flange;
- rotating the inner assembly toward a second bevel configuration, wherein in the second bevel configuration, the flange is positioned so as to contact the target tissue wall before, or at the same time as, the tip end;
- proximally retracting the inner assembly such that the flange abuts an interior surface of the target tissue wall;
- advancing an outer assembly distally toward the target tissue wall over the inner assembly, wherein the outer assembly includes a second beveled tip removeably coupled to a second shaft, wherein the advancing the outer assembly includes advancing the outer assembly until the second beveled tip contacts a skin of the subject or an exterior surface of the target tissue wall;
- coupling the first beveled tip to the second beveled tip so as to clamp tissue therebetween;
- delivering a plug assembly through the inner assembly until a plug of the plug assembly engages the first beveled tip, thereby closing the opening, the plug assembly including the plug removably coupled to a plug shaft;
- and
- removing the first shaft from the first beveled tip, the second shaft from the second beveled tip, and the plug shaft from the plug.
