Methods for sealing a vascular puncture
View Patent ↗A method for sealing a puncture through a vessel wall using a sealing device including an elongate tubular body, a balloon carried by the body, an outer tubular member carried over the elongate tubular body, and a sealant carried by the elongate tubular body adjacent the balloon. Retracting the outer tubular member exposes the sealant.
1. A method of sealing a puncture through a vessel wall, comprising the steps of:
positioning a sealing device through a vascular puncture such that an inflatable balloon carried by an elongate, tubular body and an outer tubular member extend into the vessel, and a sealant is carried by the elongate tubular body adjacent the balloon prior to positioning the sealing device through the vascular puncture;
inflating the balloon inside of the vessel;
retracting the outer tubular member to expose the sealant;
deflating the balloon; and
retracting the balloon through the sealant, leaving the sealant in place.
2. A method of sealing a puncture through a vessel wall as in claim 1 , further comprising the step of tamping the sealant.
3. A method of sealing a puncture through a vessel wall as in claim 2 , wherein the tamping step is accomplished using an elongate tamping tube, slidably carried inside of the outer tubular member.
4. A method of sealing a puncture through a vessel wall as in claim 1 , further comprising the step of proximally retracting the tubular body following the inflation step to seat the balloon against the vessel wall.
5. A method of sealing a puncture through a vessel wall as in claim 3 , further comprising the step of proximally retracting the balloon through the tamping tube.
