Abstract

Some embodiments of the invention provide an apparatus for achieving hemostasis in a puncture tract that is created during a medical procedure. The puncture typically extends from the epidermis to the vasculature in a living organism. In some embodiments, the apparatus includes (1) a plug for subcutaneous placement within the puncture tract, and (2) a delivery mechanism for delivering and maintaining the plug within the puncture tract until hemostasis is achieved. In some embodiments, the delivery mechanism and its associated plug are removed after hemostasis has been achieved. In this manner, the delivery mechanism and its associated plug act as a disposable bandage. The plug is the component of the disposable bandage that is inserted into the puncture tract to achieve hemostasis. The plug can have many shapes. Also, in some embodiments, the plug include one or more materials (e.g., chitosan) designed to promote coagulation and thereby hemostasis. In some embodiments, the delivery mechanism allows an operator to apply pressure to maintain the plug in the puncture tract until hemostasis is achieved. In some embodiments, the delivery mechanism also occludes the opening of the puncture tract.

Claims

1. An apparatus for achieving hemostasis in a puncture tract that is created during a medical procedure on a patient, the apparatus comprising:

(a) a plug for placement within the puncture tract, and

(b) a delivery mechanism for delivering the plug into the puncture tract until hemostasis is achieved.

2. The apparatus of claim 1, wherein the delivery mechanism and the plug are removed from the puncture tract after hemostasis has been achieved.

3. The apparatus of claim 1, wherein the plug includes at least one coagulating material.

4. The apparatus of claim 1 further comprising a lumen that is defined through the plug and the delivery mechanism, said lumen for passing a wire through the plug and the delivery mechanism in order to guide the plug into the puncture tract.

5. The apparatus of claim 4 further comprising a valve for preventing blood from flowing out of the patient through the lumen while allowing the wire to pass through the lumen.

6. The apparatus of claim 1 further comprising an adhesive material for affixing the delivery mechanism to the patient while the plug is within the puncture tract.

7. The apparatus of claim 1, wherein the plug has a tapered tip for easy insertion into the puncture tract.

8. The apparatus of claim 1, wherein the delivery mechanism has a pad for abutting the patient.

9. The apparatus of claim 8, wherein the pad provides a surface for a person to apply pressure to maintain the plug within the puncture tract after the plug has entered the puncture tract.

10. A method of achieving hemostasis in a puncture tract that is created during a medical procedure on a patient, the method comprising:

(a) inserting a plug for placement within the puncture tract, and

(b) maintaining the plug in the puncture tract until hemostasis is achieved.

11. The method of claim 10 further comprising removing the plug from the puncture tract after hemostasis has been achieved.

12. The method of claim 10, wherein the plug includes at least one coagulating material.

13. The method of claim 10 passing a wire through a passageway that is defined in the plug in order to guide the plug into the puncture tract.

14. The method of claim 13 passing the wire through a valve coupled to the plug, said valve preventing blood from flowing out of the patient through the passageway while allowing the wire to pass through the passageway.

15. The method of claim 10, wherein inserting the plug comprises using a delivery mechanism, to which the plug is affixed, to insert the plug into the puncture tract, wherein the method further comprises affixing the delivery mechanism to the patient while the plug is within the puncture tract.

16. The method of claim 10, wherein the plug has a tapered tip for easy insertion into the puncture tract.

17. A method of performing a medical operation, the method comprising:

a) defining a puncture tract to access a blood vessel in a patient;

b) maintaining the plug in the puncture tract until hemostasis is achieved.

18. The method of claim 17 further comprising removing the plug from the puncture tract after hemostasis has been achieved.

19. The method of claim 17, wherein the plug includes at least one coagulating material.
