An apparatus for inhibiting blood loss from a puncture site. The apparatus may include means for locating a puncture site in a blood vessel wall. This apparatus is comprised of a tube and an elongated member that is positioned around the tube. The elongated member includes a proximal end and a distal end. Around the tube is also a dissolvable distal capsule, the distal capsule including a proximal end and a distal end, wherein the proximal end of the distal capsule attaches to the distal end of the elongated member. Inside the distal capsule is hemostatic material such as a sponge.

What is claimed is: 1. An apparatus for inhibiting blood loss from a puncture site comprising: a tube; an elongated member positioned around the tube, the elongated member including a proximal end and a distal end, the elongated member distal end defining an outer surface having a maximum profile dimension; a dissolvable distal capsule positioned around the tube, the distal capsule including a proximal end and a distal end, wherein the distal capsule proximal end defines an outer surface having a maximum profile dimension substantially equal to the maximum profile dimension of the elongated member distal end outer surface, and wherein the distal capsule proximal end is bonded to the elongated member distal end at least until exposure to bodily fluid at least partially dissolves the distal capsule thereby releasing the distal capsule from the elongated member; and hemostatic material located inside the distal capsule. 2. The apparatus according to claim 1, wherein the distal end of the dissolvable distal capsule is rounded. 3. The apparatus according to claim 1, wherein the distal capsule is made of an absorbable material. 4. The apparatus according to claim 1, wherein the distal capsule is made of a biocompatible material. 5. The apparatus according to claim 1, wherein the distal capsule is made of a gelatin film. 6. The apparatus according to claim 1, wherein the distal end of the elongated member has a substantially concave spherical shape. 7. The apparatus according to claim 1, further comprising a control tip assembly. 8. The apparatus according to claim 7, wherein the control tip assembly has a proximal end portion, a distal end portion having a distal port, and a central portion between the proximal end portion and the distal end portion, the control tip including a lumen. 9. The apparatus according to claim 8, wherein the control tip proximal end portion is externally tapered. 10. The apparatus according to claim 8, wherein the control tip distal end portion is externally tapered. 11. The apparatus according to claim 8, wherein the control tip further comprises a hole extending laterally through the central portion and connecting the control tip lumen with the exterior of the central portion. 12. The apparatus according to claim 8, wherein the control tip lumen has a substantially constant inner diameter. 13. The apparatus according to claim 8, wherein the control tip lumen has an inner diameter larger in the central portion than in the distal portion. 14. An apparatus for inhibiting blood loss from a puncture site comprising: a tube; an elongated member positioned around the tube, the elongated member including a proximal end and a distal end; a dissolvable distal capsule positioned around the tube, the distal capsule including a proximal end and a distal end, wherein the proximal end of the distal capsule attaches to the distal end of the elongated member and the distal end of the elongated member has an outer diameter which is slightly smaller than an outer diameter of the elongated member for accepting the dissolvable distal capsule; and hemostatic material located inside the distal capsule. 15. An apparatus for inhibiting blood loss from a puncture site comprising: an elongated member having a lumen for receiving a guidewire, the elongated member including a proximal end and a distal end, the elongated member distal end defining an outer surface having a maximum profile dimension; a dissolvable distal capsule positioned around the lumen, the distal capsule including a proximal end and a distal end, wherein the distal capsule proximal end defines an outer surface having a maximum profile dimension substantially equal to the maximum profile dimension of the elongated member distal end outer surface, and wherein the distal capsule proximal end is bonded to the elongated member distal end at least until exposure to bodily fluid at least partially dissolves the distal capsule thereby releasing the distal capsule from the elongated member; and hemostatic material located inside the distal capsule. 16. The apparatus according to claim 15, wherein the distal end of the dissolvable distal capsule is rounded. 17. The apparatus according to claim 15, wherein the distal capsule is made of an absorbable material. 18. The apparatus according to claim 15, wherein the distal capsule is made of a biocompatible material. 19. The apparatus according to claim 15, wherein the distal capsule is made of a gelatin film. 20. The apparatus according to claim 15, wherein the distal end of the elongated member has a substantially concave spherical shape. 21. The apparatus according to claim 15, further comprising a control tip assembly. 22. The apparatus according to claim 21, wherein the control tip assembly has a proximal end portion, a distal end portion having a distal port, and a central portion between the proximal end portion and the distal end portion, the control tip including a lumen extending from the distal port. 23. The apparatus according to claim 22, wherein the control tip further comprises a hole extending laterally through the central portion and connecting the control tip lumen with the exterior of the central portion. 24. An apparatus for inhibiting blood loss from a puncture site comprising: an elongated member having a lumen for receiving a guidewire, the elongated member including a proximal end and a distal end; a dissolvable distal capsule positioned around the lumen, the distal capsule including a proximal end and a distal end, wherein the proximal end of the distal capsule attaches to the distal end of the elongated member and the distal end of the elongated member has an outer diameter which is slightly smaller than an outer diameter of the elongated member for accepting the dissolvable distal capsule; and hemostatic material located inside the distal capsule. 25. A system for locating a puncture site in a blood vessel wall and for inhibiting blood loss from the puncture site comprising: hemostatic material delivery system having a tube; an elongated member positioned around the tube and having a distal end defining an outer surface having a maximum profile dimension, a dissolvable distal capsule positioned around the tube and having a proximal end defining an outer surface having a maximum profile dimension substantially equal to the maximum profile dimension of the elongated member distal end outer surface, the distal capsule proximal end being bonded to the elongated member distal end at least until exposure to bodily fluid at least partially dissolves the distal capsule thereby releasing the distal capsule from the elongated member, and hemostatic material located inside the distal capsule; and a control tip assembly having a control tip and a control tip body.
