Claims
- 1. A system for delivering a pledget of hemostasis promoting material to a blood vessel puncture to facilitate hemostasis, the system comprising:
an introducer sheath having a proximal end; a pledget handling system configured to receive a pledget of hemostasis promoting material, said pledget handling system having a connector configured to be connected to the proximal end of said introducer sheath, said pledget handling system comprising a valve to permit a user to control the staging and delivery of the pledget; and, a control tip coupled to said pledget handling system.
- 2. A system according to claim 1 wherein said pledget handling system comprises a body which is substantially cylindrical.
- 3. A system according to claim 1 wherein said pledget handling system comprises a delivery syringe.
- 4. A system according to claim 1 wherein said pledget handling system comprises a hose connected to provide fluid flow communication between said delivery syringe and said valve.
- 5. A system according to claim 4 wherein at least two connectors are connected to said hose to permit a user to connect a hydration chamber to said hose at a selected connector.
- 6. A system according to claim 1 wherein said valve is constructed to allow the user to control the flow of fluid from the distal end of said pledget handling system.
- 7. A system according to claim 1 wherein said valve is constructed to allow the user to control the hydration, staging and delivery of the pledget.
- 8. A method of promoting hemostasis of a blood vessel puncture using a pledget handling system which includes a valve, the method comprising:
locating a pledget inside a hydration means; connecting said hydration means to said pledget handling system; setting the valve to a first position and hydrating the pledget in said hydration means; thereafter setting the valve to a second position and staging the pledget in said pledget handling system; and, thereafter setting the valve to a third position and delivering the pledget to promote hemostasis of the blood vessel puncture.
- 9. A method according to claim 8 wherein when the valve is in the first position the valve prevents fluid from flowing from the distal end of the pledget handling system.
- 10. A method according to claim 8 wherein the step of hydrating the sponge material includes applying pressurized fluid to the sponge material.
- 11. A method according to claim 8 wherein when the valve is in the second position the valve allows fluid to flow from the pledget handling system at a controlled rate while preventing the sponge material from traveling out of the pledget handling system.
- 12. A system for delivering a pledget of hemostasis promoting material to a blood vessel puncture to facilitate hemostasis, the system comprising:
an introducer sheath; a control tip coupled to said introducer sheath; and, seal means disposed around a portion of said control tip to prevent blood from passing through said introducer sheath.
- 13. A system according to claim 12 wherein said seal means is flexible.
- 14. A system according tom claim 12 wherein said seal means if deformable.
- 15. A system according to claim 12 wherein said control tip comprises an enlarged distal end and said seal means is connected to said enlarged distal end.
- 16. A system according to claim 15 wherein said seal means comprises a deformable conical portion and a cylindrical portion.
