Apparatus and methods for facilitating access through a puncture including sealing compound therein
First Claim
1. Apparatus for introducing an instrument into a body lumen of a patient through a puncture extending from the patient'"'"'s skin to the body lumen, comprising:
- a guidewire;
a sealing compound in a form that can be delivered into the puncture around the guidewire; and
an instrument introducer assembly comprising a tubular sheath having a proximal end, a distal end shaped for insertion into the puncture, and a lumen extending from the proximal end to an opening in the distal end, and a flexible, thin-walled sleeve comprising first and second ends, and a hub on the first end disposed adjacent the distal end of the sheath, the second end extending into the distal opening and lumen of the sheath, the hub being slidable along an exterior of the sheath for drawing the sleeve out of the distal sheath opening and along the sheath exterior.

Abstract
Apparatus for delivering a sleeve into a puncture through tissue includes a tubular sheath including a lumen extending between its proximal end and an opening in its distal end. The sleeve includes a hub on a first end thereof disposed adjacent the distal end of the sheath, and a second end extending into the opening and lumen of the sheath. The hub is slidable along an exterior of the sheath for drawing the sleeve out of the opening and along an exterior of the sheath. During use, a guide wire is placed through the puncture into a blood vessel, and sealing compound is introduced into the puncture around the guide wire. The sheath is advanced into the puncture over the guidewire while maintaining the hub adjacent the patient'"'"'s skin, causing the sleeve to be deployed from the sheath and line the puncture as the sheath is advanced into the puncture.

11. A method for lining a puncture extending from a patient'"'"'s skin to a body lumen using a tubular sheath and a flexible, thin-walled sleeve disposed within a lumen of the tubular sheath, the sleeve comprising a hub on a first end thereof adjacent a distal end of the sheath and a second end disposed within the lumen of the sheath, the method comprising:
-
placing a guide wire through the puncture from the patient'"'"'s skin into the body lumen;
introducing a sealing compound into the puncture around at least a portion of the guide wire;
placing the hub of the sleeve adjacent the patient'"'"'s skin; and
advancing the sheath into the puncture over the guidewire, while maintaining the hub adjacent the patient'"'"'s skin, causing the sleeve to be deployed from the lumen of the tubular sheath and cover an exterior of the sheath to thereby line the puncture as the sheath is advanced into the puncture. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)

20. A system for introducing an instrument into a body lumen of a patient through a puncture extending from the patient'"'"'s skin to the body lumen, comprising:
-
a sealing compound delivery assembly including a sealing compound, and a tubular sheath having a first lumen sized for allowing passage there through of a guidewire, and a second lumen at least partially surrounding and isolated from the first lumen, the second lumen in communication with an inlet port for receiving the sealing compound and one or more outlet ports for dispensing the sealing compound within the puncture while a guidewire is positioned in the first lumen; and
an instrument introducer assembly including a tubular sheath having a proximal end, a distal end shaped for insertion into the puncture, and a lumen extending from the proximal end to an opening in the distal end, and a flexible, thin-walled sleeve comprising first and second ends, and a hub on the first end disposed adjacent the distal end of the sheath, the second end extending into the distal opening and lumen of the sheath, the hub being slidable along an exterior of the sheath for drawing the sleeve out of the distal sheath opening and along the sheath exterior.
