US Patent:

20010053920, Dec 20, 2001

Filed:

Mar 27, 2001

Appl. No.:

09/818181

Inventors:

Reza Shaker - Brookfield WI, US

Assignee:

Wilson-Cook Medical Inc. - Winston-Salem NC

International Classification:

A61M029/00

US Classification:

606/197000

Abstract:

An apparatus and method are disclosed for measuring the compliance of the lower esophageal sphincter (LES), the apparatus comprises a catheter having a plurality of extendable members disposed therealong for both measuring the compliance of the LES and stimulating the esophagus which relaxes the LES to obtain a more clinically relevant measurement of LES compliance. In one embodiment, the plurality of extendable members include a first balloon which is located and inflated within the esophagus to trigger esophageal motility, a second, non-elastic balloon that is positioned within the LES, and a third balloon which is inflated within the stomach to help align the second balloon with LES. Incrementally increasing volumes of air are introduced into the second balloon, with the resulting pressures exerted by the LES calculated and compared to normative values to assess the condition of the LES.

Inventors:

Reza Shaker - Brookfield WI, US

International Classification:

A61B 5/00
A61F 2/50
A61B 5/103

US Classification:

600593, 600 37

Abstract:

An esophageal device is used to recognize, diagnose, characterize, or relieve an impact of an abnormal or defective UES anatomy, physiology, or functionality. In one implementation, the esophageal device measures a UES response to esophageal fluid infusion to detect or characterize an abnormality or defective UES anatomy, physiology, or functionality. An Upper Esophageal Sphincter compression device is used to increase intra-luminal pressure within the Upper Esophageal Sphincter of a patient in order relieve an impact of an abnormal or defective UES anatomy, physiology, or functionality.

International Classification:

A61B 17/135
A61B 17/132

Abstract:

A compression device is used to increase intra-luminal pressure within the upper esophageal sphincter of a patient in order relieve an impact of an abnormal or defective upper esophageal sphincter anatomy, physiology, or functionality. In one implementation, the compression device is used in conjunction with an external pressure sensing device to determine the external pressure that is to be applied to the cricoid for a specific patient. The compression device can be a means for the management and/or treatment of abnormal upper esophageal sphincter functionality, or a means for strengthening an esophageal sphincter of a subject, or a means for curing esophageal reflux disease of a subject, or a means for improving vocal function in a subject, or a means for managing lung aspiration, or a means for applying cricoid pressure during anesthesia intubation, or a means for stabilizing body structures such as during medical imaging or radiation treatment.
