Appl. No.:

09/702155

Inventors:

Katsumi Oneda - Alpine NJ
Edward Paul Harhen - Duxbury MA

Assignee:

Vision Sciences, Inc. - Natick MA

International Classification:

A61M 500

US Classification:

600116, 606194

Abstract:

Apparatus and methods for attaching and forming enclosed inflatable members on an endoscope assembly with a disposable sheath are disclosed. In one embodiment, an apparatus includes a flexible and resilient cuff member that is positioned on the outer surface of the disposable sheath and sealably and fixedly bonded to the sheath cover material at the cuff edges to form an annular space capable of being inflated. The inflatable member formed thereby is inflated through a lumen internal to the sheath that has an opening into the interior annular space. In another embodiment, the annular space may be divided into separate inflatable lobes. In still another embodiment, the cuff member is a flexible and resilient member that is substantially toroidal in shape that is positioned on the outer surface of the sheath. In a further embodiment, the inflatable member is formed from an excess length of sheath cover material disposed on the disposable sheath. A single reentrant fold of sheath material is formed with an edge that is sealably and fixedly bonded to the sheath cover material to form an annular space capable of inflation.

International Classification:

A61B 104

US Classification:

600121, 600114

Abstract:

A thin-walled elastic sheath that can be stretched axially over an elongated imaging device to closely conform to the device and isolate the device from an external environment, and a method of forming such a sheath, are shown and described. The method includes the steps of heating at least a portion of a sheet of an elastomeric material to an elevated temperature to form a malleable heated portion of the sheet, pressing an elongated forming tool against the sheet at a location central with respect to the heated portion of the sheet, stretching the heated portion of the elastomeric material with the forming tool until an elastic conforming portion of the sheet is conformed to at least a portion of the length of the forming tool, and removing the forming tool from the conforming portion of the sheet to leave the thin-walled, elastic sheath having a wall thickness approximately equal to or less than 0. 006 inches.

Abstract:

Apparatus and methods for obtaining biopsy samples using an endoscope assembly are disclosed. In one embodiment, an assembly adapted for use with an endoscopic insertion tube includes a sheath having a body portion adapted to at least partially encapsulate a distal portion of the insertion tube, and a biopsy sampling device attached to the sheath and including a collection member proximate an end of the body portion. The biopsy sampling device may be attached to the body portion of the sheath, or alternately, may be attached to an enclosed distal end of the sheath. The assembly may also include a cover attached to the sheath and positionable proximate the biopsy sampling device. An actuation member may be attached to the cover and may extend along the sheath, allowing the operator to actuate the cover between a covered position and a collecting position.

Abstract:

In one embodiment, an apparatus includes a flexible and resilient cuff member that is positioned on the outer surface of the disposable sheath and sealably and fixedly bonded to the sheath cover material at the cuff edges to form an annular space capable of being inflated. The inflatable member formed thereby is inflated through a lumen internal to the sheath that has an opening into the interior annular space. The inflatable member may be inflated to exert a longitudinal force on the insertion tube, thereby moving the endoscope assembly along a body passage. Alternately, a sheath may include a plurality of inflatable cuffs that may be inflated to create an isolated space therebetween within the body passage.

US Classification:

600109

Abstract:

A method of examining internal body portions of patients. The method includes providing an imaging capsule including an image capturing unit, mounting the imaging capsule on a first elongate tube suitable for insertion into a body cavity, in a manner which prevents release of the imaging capsule from the first elongate tube within a body cavity, inserting the first elongate tube with the capsule mounted thereon into a patient, retracting the first elongate tube from the patient, separating the imaging capsule from the first elongate tube, disposing of the first elongate tube, mounting the imaging capsule on a second elongate tube and inserting the second elongate tube with the imaging capsule mounted thereon into a patient.
