Benefits of technology

"The present invention provides a device and method for effecting hemostasis at a wound site with an indwelling tubular element, such as a catheter, using a positive charge to quickly create a coagulation process and hemostasis. This approach is faster and more efficient than traditional methods and can be used even in the presence of anticoagulants. The device can be incorporated into various forms, such as pads, fibers, and liquids, and can be used with iontophoretic equipment to apply a positive charge to the wound site. The invention allows for even application of pressure to the wound site and easy removal of the tubular element. The method includes applying pressure to the puncture wound and maintaining the force for a predetermined time period. Overall, the invention provides a new and important process for the treatment of disease processes and minimally invasive procedures."

Problems solved by technology

The situation is complicated further by the use of anticoagulants in these procedures, which prolongs clotting times. Substances such as heparin, aspirin, coumadin, and other anticoagulants are used with regularity and affect the normal blood coagulation cascade.

Embodiment Construction

[0027] The present invention is described hereinafter with specific references to the use of the present invention for sealing an incision or puncture wound with an indwelling tubular element, such as catheter, introducer or tube, through the incision or puncture wound. It is contemplated that the present invention may be used with any catheterization or other medical procedure such as laparoscopic or other minimally or less invasive surgeries wherein it is desirable to seal an incision or puncture wound in the patient to prevent the loss of the patient's body fluid therethrough.

[0028]FIG. 1 is a top view of one preferred embodiment of the present inveniton. Referring to FIG. 1, a pad 10 defines an opening 12 through the pad 10. In a preferred embodiment, the opening is constructed as a slit or an elongated cut 26. As shown in FIG. 1, the slit 26 extends from an approximately central point to an edge of the pad 10. The slit is preferably sized to permit egress of an indwelling tubu...

Abstract

The present invention relates generally to medical devices for applying hemostatic composition to a puncture or wound site with indwelling tubular element, such as catheter, introducer or tube therein, particularly a hemostatic pad with an opening therethrough in order to allow egress of the indwelling tubular element through the hemostatic pad as the hemostatic pad provide hemostasis at the hemorrhaging site. The device may be applied to, or removed from, the wound site while the tubular element is in place. A method for effecting hemostasis at a puncture wound, includes applying pressure proximal to the puncture wound, and directing a cationic biopolymer of glucosamine application surface of a closure pad against the puncture wound with force sufficient to prevent fluid from exiting the puncture wound. Then the pressure proximal to the puncture wound is removed and the force on the closure pad is maintained for at least a first predetermined time period. The force on the closure pad is removed if hemostasis is verified. The puncture wound may then be dressed over the closure pad, and the dressing and the closure pad removed after a second predetermined time period.

Description

REFERENCE TO RELATED APPLICATION [0001] This application is a continuation in part of U.S. patent application Ser. No. 10 / 008,052, filed Nov. 13, 2001, the disclosure of which is incorporated herein by reference.FIELD OF THE INVENTION [0002] The present invention relates to medical devices for hemostasis, and methods of using the medical devices for hemostasis. More particularly, the present invention relates to medical devices for effecting hemostasis at a puncture wound with an indwelling tubular element extending therethrough. BACKGROUND OF THE INVENTION [0003] Puncture of blood vessels is a necessary stage in many of the minimally invasive approaches to diagnosis and treatment, including interventional radiology and cardiology. Therefore, a need to create hemostasis as rapidly as possible following the procedure becomes an important priority. [0004] Various hemostatic agents, such as synthetic or natural cationic polymers, hydrogels, collagen based products, oxidized cellulose, ...
