Abstract
The present invention relates to an apparatus and a method for sealing a puncture in a tubular tissue structure or the wall of a body cavity. More specifically, the present invention is directed to an apparatus and method for sealing a puncture site in the wall of a tubular tissue structure, or in the wall of a body cavity with a stabilizer used to stabilize the material used to seal the puncture site as the material is positioned. The material is inserted into the puncture site as a ribbon or sheet on an introducer element such as a needle, a cannula, a guide wire, an introducer element adapted for dialysis, an introducer element adapted for catheterization, a trocar, or any other introducer element used to access the lumen of a tubular tissue structure or used to access a body cavity.
Claims19
A method of sealing a puncture site in the wall of a tubular tissue structure or in the wall of a body cavity, said method comprising the steps of:
- inserting an introducer into the puncture site, the introducer having a sheath, a sheath cap, a stabilizer detachably coupled to the sheath, wherein the stabilizer, upon detachment from the sheath is free to move in an axial direction relative to the sheath, and a ribbon or sheet of material, wherein the ribbon or sheet of material has at least one tether, an extended portion and a cuff, wherein the cuff of the ribbon or sheet remains outside of the punctured wall and the extended portion of the ribbon or sheet is positioned in the lumen of the tubular tissue structure or the body cavity;
- detaching the stabilizer from the sheath, and axially moving the stabilizer relative to the sheath to contact the cuff and to stabilize the cuff relative to the puncture site;
- and
- positioning the ribbon or sheet to substantially seal the puncture site while the stabilizer is in contact with the cuff.
An apparatus for sealing a puncture site in the wall of a tubular tissue structure or the wall of a body cavity in a patient, the apparatus comprising:
- an introducer element having a sheath;
- a sheath cap;
- a ribbon or sheet of material having an extended portion and a cuff, wherein the ribbon or sheet of material is detachably coupled to the sheath;
- a tether coupled to the ribbon or sheet of material to manipulate the shape or position of the material;
- and
- a stabilizer detachably coupled to the sheath, wherein the stabilizer, upon detachment from the sheath, is free to move in an axial direction relative to the sheath whereby to contact and stabilize the cuff relative to the puncture site.
