Filed:

Mar 26, 2004

Appl. No.:

10/810354

Inventors:

Andrew Beckman - Cincinnati OH, US
Fidelis Onwumere - Mansfield TX, US
Michael Ludzack - Maineville OH, US
Charles Samples - Akron OH, US
Ana Barbur - Hudson OH, US

International Classification:

A61N005/00

US Classification:

600431000

Abstract:

The present invention includes methods and materials for implantable devices (markers) which are disclosed for permanently marking the location of a biopsy or surgery for the purpose of identification. The devices are remotely delivered, preferably percutaneously. Visualization of the markers is readily accomplished using various state of the art imaging systems. Preferred visualization is through MRI, X-ray and ultrasound. The markers function to provide evidence of the location of the lesion after the procedure is complete for reference during future examinations or procedures.

A61F 544

US Classification:

604 54

Abstract:

A catheter assembly for collecting fluid from a tubular organ into a drainage system includes a tubular body portion (12) having an end portion (14) and an intermediate portion (16) adjacent thereto. The end portion (14) includes a retaining balloon (30) for retaining the intermediate portion (16) within the tubular organ. The intermediate portion (16) includes a portion having an outer diameter smaller than the inner diameter of the catheterized tubular organ for allowing the free flow of fluid from the tubular organ and over the intermediate portion (16) to maintain the tubular organ infection free. A collection mechanism is operatively connected to the intermediate portion (16) and spaced from the end portion (14). The collection mechanism is insertable into the tubular organ for collecting the fluid flowing over the intermediate portion (16) and preventing fluid from escaping from the drainage system. A method of using the catheter assembly (10) is also disclosed.
