US Patent:

20090157002, Jun 18, 2009

Filed:

Dec 14, 2007

Appl. No.:

11/956890

Inventors:

John A. Dumot - Chagrin Falls OH, US
Timothy E. Askew - Baltimore MD, US
Jennifer Cartledge - Clemson SC, US

Assignee:

CSA MEDICAL, INC. - Baltimore MD

International Classification:

A61M 1/00
A61M 25/00
A61B 18/02

US Classification:

604131, 604523, 604265, 606 21

Abstract:

A catheter having a plurality of longitudinal lumens for removing biological, natural and/or man-made materials from cavities, ducts, vessels, or other locations in a patient's body. The multi-lumen catheter comprises a longitudinally-extending suction lumen with suction holes through which materials pass into the lumen in response to suction forces generated by a source of negative pressure coupled to a proximal end of the lumen. A longitudinally-extending vent lumen coupled to a source of at least neutral vent pressure through, for example, an opening to ambient air at the proximal end of the lumen, and preferably, through vent holes disposed along a length of the catheter. A dividing septum between the adjacent lumens has one or more ports fluidically coupling the lumens. The ratio of the area of the suction holes and ports is such that the suction force at unobstructed suction holes is maintained below a desired maximum force for a given negative pressure when none or more of the suctions holes are obstructed. When a suction hole obstruction occurs, fluid is drawn into the suction lumen through the communication port(s). This compensating fluid flow prevents the suction forces from exceeding a predetermined maximum value during use even when one or more suction holes become obstructed. This maximum force may be set, for example, to avoid hematoma, to permit repositioning of the catheter during use, etc. thereby allowing for continuous suction.

Appl. No.:

12/022013

Inventors:

Timothy E. Askew - Baltimore MD, US

Assignee:

CSA Medical, Inc. - Baltimore MD

International Classification:

A61B 18/02

US Classification:

606 21

Abstract:

Systems and methods for delivering cryosurgical treatment. The cryosurgery system comprises a cryogen delivery apparatus configured to deliver a spray of cryogen to target tissue of a patient and an indirect visualization apparatus configured to provide indirect visualization of the target tissue during the cryogen delivery. The indirect visualization apparatus and the cryogen delivery apparatus are constructed and arranged to be operationally unintegrated and physically spaced with respect to each other during the delivery of the cryogen.
