Problems solved by technology

Certain medical procedures result in bleeding penetration wounds inside the body, for example via the insertion of devices into blood vessels and / or organs.
Several important limitations are associated with the use of standard compression.
The most painful aspects of the catheterization procedure reported by patients are the standard compression procedure and lying immobile for hours.
The aggressive use of anticoagulants and antiplatelet therapies to prevent thrombus formation during catheterization procedures has greatly increased the difficulty of sealing the access site using compression.
Finally, complications occur, the most frequent of which are the formation of hematomas, pseudo-aneurysms, and / or arteriovenous fistulae.
However, these products are invasive, implant foreign materials, require skill and training to use, and can cause major complications.

Embodiment Construction

[0081] Disclosed herein are systems and methods associated with an acoustic hemostasis device. This device, designed for rapid, noninvasive sealing of femoral arteriotomies using focused ultrasound technology, requires neither the prolonged application of pressure and immobilization associated with standard compression, nor implantation of any foreign material. Thus, this system has the potential to provide a superior method of arteriotomy closure. This system has been also described in U.S. Pat. No. 6,656,136, filed Oct. 25, 2000; co-pending U.S. application Ser. No. 10 / 671,417 filed Sep. 24, 2003; U.S. Pat. No. 6,719,694, filed Dec. 22, 2000; and U.S. Pat. No. 6,626,855, filed Nov. 22, 2000; all of which are incorporated herein by reference in their entirety.

[0082] Because of its unique properties in soft tissue, medical ultrasound can be brought to a tight focus at a distance from its source. FIG. 1 depicts an ultrasound applicator 20 emitting focused ultrasound to a focal volum...

Abstract

Systems and methods for sealing a vascular opening such as an arteriotomy formed during a femoral artery catheterization procedure are described. The blood vessel is transiently occluded during application of therapeutic energy, such as high intensity focused ultrasound. The occlusion improves the efficiency of the therapy without causing damage to the blood vessel. Also described are methods for locating the arteriotomy, aligning the therapeutic applicator to the arteriotomy, and a station keeping procedure for maintaining alignment.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This application claims the benefit of U.S. Provisional Application No. 60 / 728,783, filed Oct. 20, 2005 and U.S. Provisional Application No. 60 / 808,665, filed May 26, 2006, both of which are incorporated herein by reference in their entirety.BACKGROUND [0002] 1. Field of the Invention [0003] This disclosure relates to systems of methods for locating arteriotomies. In some embodiments, the localization is used for therapeutic targeting (e.g., for targeting of high-intensity focused ultrasound). [0004] 2. Description of the Related Art [0005] Certain medical procedures result in bleeding penetration wounds inside the body, for example via the insertion of devices into blood vessels and / or organs. Representative procedures include arterial and venous catheterization for cardiologic or radiologic interventional procedures, needle biopsy procedures, and minimally invasive surgery. Improved percutaneous catheterization techniques have enabled...
