Vascular sealant delivery device and sheath introducer and method
A sheath introducer is inserted through the skin and into a body lumen, e.g., the femoral artery, for a medical procedure. Upon completion of the medical procedure, the sheath introducer is partially withdrawn from the body lumen so that at least one through-wall hole in a body region of the sheath introducer is positioned outside the body lumen, but under the skin. An opening in a distal end tip of the sheath introducer is sealed so that no blood is flowing into the sheath introducer the after sheath introducer is partially withdrawn. A surgical sealant is injected into the sheath introducer and flows out of the at least one through-wall hole and surrounds the access site. After injection of the surgical sealant, the sheath introducer is removed. The surgical sealant seals the puncture and minimizes any blood flow from the body lumen through the puncture.
1. A method comprising:
plugging a distal end tip of a sheath introducer having at least one through-wall hole with a dilator plug of a dilator wherein said dilator is inserted through said sheath introducer;
positioning said sheath introducer so that said at least one through-wall hole is outside a body lumen;
injecting a surgical sealant into said sheath introducer, wherein said surgical sealant passes from said sheath introducer through said at least one through-wall hole,
wherein the method further comprises:
inserting, prior to said plugging, said positioning, and said injecting, said sheath introducer into said body lumen;
performing, prior to said plugging, said positioning, and said injecting, a medical procedure, using a device inserted into said body lumen through said sheath introducer; and
removing, prior to said plugging, said positioning, and said injecting and following completion of said performing said medical procedure, said device from said body lumen and from said sheath introducer.
2. The method of claim 1 further comprising:
blocking said body lumen using a balloon clamp catheter.
3. The method of claim 2 further comprising:
removing said sheath introducer from said body lumen following said injecting.
4. The method of claim 3 further comprising:
removing said balloon clamp catheter from said body lumen.
5. The method of claim 1 further comprising:
removing said sheath introducer from said body lumen following said injecting.
6. The method of claim 1 wherein said positioning further comprises:
obtaining a back bleed; and
removing said sheath introducer from said body lumen until said back bleed stops.
7. The method of claim 6 further comprising:
maintaining a position of said sheath introducer, following completion of said positioning, for said injecting.
8. A method comprising:
inserting a sheath introducer into a body lumen;
performing a medical procedure using a device inserted into said body lumen through said sheath introducer;
removing said device from said body lumen and said sheath introducer;
plugging, following said inserting, said performing, and said removing, a distal end tip of said sheath introducer with a dilator plug of a dilator, wherein said sheath introducer includes at least one through-wall hole, and further wherein said dilator is inserted through said sheath introducer;
positioning said sheath introducer so that said at least one through-wall hole is outside said body lumen, wherein said positioning comprises:
obtaining a back bleed; and
withdrawing said sheath introducer from body lumen until said back bleed stops; and
injecting a surgical sealant into said sheath introducer, wherein said surgical sealant passes from said sheath introducer through said at least one through-wall hole .
9. The method of claim 8 further comprising:
maintaining a position of said sheath introducer, following completion of said positioning, for said injecting.
