A device for sealing a puncture in a patient includes a sealing component including an elongate control member configured to pass through a puncture in skin of a patient. The sealing component also includes an expandable member disposed near a distal end of the control member, and a tip releasably attached to the elongate control member distal to the expandable member. The device also includes a sealing material delivery component including a delivery tube through which the control member of the sealing component is configured to extend. The delivery tube is configured to deliver sealing material through an opening in a distal end of the delivery tube.

1. A method of sealing a puncture in a wall of a body cavity of a patient, the method including: inserting a sealing component and a sealing material delivery component through a puncture in a wall of a body cavity of a patient, the sealing material delivery component including a delivery tube, the
1. A method of sealing a puncture in a wall of a body cavity of a patient, the method including: inserting a sealing component and a sealing material delivery component through a puncture in a wall of a body cavity of a patient, the sealing material delivery component including a delivery tube, the sealing component being slidably disposed in the delivery tube and including an elongate control member;inserting an expandable member connected to the elongate control member through the puncture into the body cavity;expanding the expandable member when the expandable member is distal to a distal end of the delivery tube and inserted in the body cavity;moving the expandable member near a distal surface of the wall of the body cavity;delivering sealing material through the distal end of the delivery tube and into the puncture;inserting a tip disposed on the elongate control member and distal to the expandable member into the sealing material;detaching the tip from the elongate control member when the tip is in the sealing material. 2. The method of claim 1, further including withdrawing the elongate control member from the patient, wherein the tip is inserted into the sealing material when the elongate control member is at least partially withdrawn from the patient. 3. The method of claim 1, wherein the elongate control member is moved proximally with respect to the sealing material delivery component so that the tip is inserted into the sealing material. 4. The method of claim 1, wherein the sealing material is delivered to surround the elongate control member proximal to the wall of the body cavity. 5. The method of claim 4, wherein the tip is inserted into a cavity in the sealing material when the elongate control member is removed from the sealing material. 6. The method of claim 1, wherein the sealing material is delivered to surround an insert member on the elongate control member disposed proximal to the wall of the body cavity and distal to the distal end of the delivery tube. 7. The method of claim 6, further including removing the insert member from the sealing material to form a cavity in the sealing material. 8. The method of claim 7, wherein the elongate control member is moved proximally with respect to the sealing material delivery component to insert the tip in the sealing material and to remove the insert member from the sealing material. 9. The method of claim 7, wherein the tip is detached from the elongate control member when the tip is inserted into the cavity in the sealing material. 10. The method of claim 7, wherein the insert member is expandable, and the method further includes: expanding the insert member before surrounding the insert member with the sealing material;collapsing the insert member before removing the insert member from the sealing material to form the cavity. 11. The method of claim 7, wherein the sealing material is a first sealing material and the cavity is a first cavity, the first sealing material being delivered to surround the distal end of the delivery tube, and the method further includes: removing the delivery tube from the first sealing material to form a second cavity in the first sealing material;delivering a second sealing material to the second cavity. 12. The method of claim 11, wherein the second sealing material is delivered using the delivery tube or a guide sheath. 13. The method of claim 1, wherein the tip is bioabsorbable. 14. The method of claim 1, wherein the tip includes a main body and at least one projection extending outward from the main body. 15. The method of claim 14, wherein the at least one projection includes one of a barb, a ring formed integrally with the main body, and a ring formed of a different material than the main body. 16. The method of claim 1, wherein the tip includes at least one of a suture, a disc, pliable material, an expandable material, and a stretchable braid. 17. The method of claim 1, wherein the tip includes at least one of a distal flange and a proximal flange. 18. The method of claim 1, wherein: the sealing material is a first sealing material;the tip is inserted into and extends at least partially through a cavity in the first sealing material;the tip abuts a surface of a second sealing material delivered inside the puncture through the delivery tube or a guide sheath. 19. The method of claim 1, wherein the tip is detached from the elongate control member using a release mechanism. 20. The method of claim 1, further including applying a tensile force to the tip to separate the tip from the elongate control member. 21. A method of sealing a puncture in a wall of a body cavity of a patient, the method including: inserting a sealing component and a sealing material delivery component through a puncture in a wall of a body cavity of a patient, the sealing material delivery component including a delivery tube, the sealing component being slidably disposed in the delivery tube and including an elongate control member;inserting an expandable member releasably connected to the elongate control member through the puncture into the body cavity;expanding the expandable member when the expandable member is distal to a distal end of the delivery tube and inserted in the body cavity;moving the expandable member near a distal surface of the wall of the body cavity;delivering a sealing material through the distal end of the delivery tube and into the puncture;collapsing the expandable member;inserting the collapsed expandable member in a cavity formed in the sealing material;expanding the expandable member in the cavity formed in the sealing material;detaching the expandable member in the expanded configuration from the elongate control member when the expandable member is in the sealing material. 22. The method of claim 21, wherein the collapsed expandable member is inserted into the cavity by at least partially withdrawing the elongate control member from the patient. 23. The method of claim 21, wherein the expandable member is bioabsorbable. 24. The method of claim 21, wherein the sealing material is delivered to surround the elongate control member proximal to the wall of the body cavity.
