Abstract
Provided is a method of cleaning a body cavity using a device by coupling a distal end portion of a first cannula to the housing such that a lumen is in fluid communication with the first portion of the inner volume, the first cannula coupled to a vacuum source, then coupling a distal end portion of a second cannula to the housing such that a lumen is in fluid communication with the second portion of the inner volume, the second cannula being coupled to a fluid source, inserting a portion of the housing into a body cavity, conveying a fluid from the fluid source to the body cavity via the lumen of the second cannula, and withdrawing the fluid from the body cavity into the vacuum source concurrently with the conveying the fluid, via the lumen of at least the first cannula.

A method of cleansing a body cavity using a device including a housing that defines a first plurality of openings in fluid communication with a first portion of an inner volume defined by the housing and a second plurality of openings in fluid communication with a second portion of the inner volume fluidically isolated from the first portion of the inner volume, the method comprising:
- coupling a distal end portion of a first cannula to the housing such that a lumen defined by the first cannula is in fluid communication with the first portion of the inner volume, a proximal end portion of the first cannula being operatively coupled to a vacuum source;
- coupling a distal end portion of a second cannula to the housing such that a lumen defined by the second cannula is in fluid communication with the second portion of the inner volume, a proximal end portion of the second cannula being operatively coupled to a fluid source;
- inserting at least a portion of the housing into a body cavity such that each of the first plurality of openings and the second plurality of openings is disposed within the body cavity;
- conveying a fluid from the fluid source to the body cavity via the lumen defined by the second cannula, the second portion of the inner volume, and the second plurality of openings;
- and
- withdrawing the fluid from the body cavity into the vacuum source, substantially concurrently with the conveying the fluid, via the lumen defined by the first cannula, the first portion of the inner volume, and the first plurality of openings,
- wherein the device comprises a proximal seal member disposed within the inner volume and having a first coupling portion and a second coupling portion,
- wherein coupling the distal end portion of the first cannula to the housing comprises coupling the distal end portion of the first cannula to the first coupling portion of the proximal seal member to place the lumen of the first cannula in fluid communication with the first portion of the inner volume,
- wherein the device comprises a first conduit disposed within the inner volume, the first conduit defines a lumen in fluid communication with the second portion of the inner volume and having a proximal end coupled to the second coupling portion of the proximal seal member, and
- wherein coupling the distal end portion of the second cannula to the housing comprises coupling the distal end portion of the second cannula to the second coupling portion of the proximal seal member to place the lumen of the second cannula in fluid communication with the second portion of the inner volume via the lumen of the first conduit.
A method of cleansing a body cavity comprising:
- coupling a distal end portion of a first cannula to a first opening of a proximal seal member disposed at least partially with a housing of a cleansing device such that a first lumen defined by the first cannula is in fluid communication with a first portion of an inner volume defined by the housing, wherein a proximal end portion of the first cannula is operatively coupled to a vacuum source;
- coupling a distal end portion of a second cannula to a second opening of the proximal seal member such that a second lumen defined by the second cannula is in fluid communication with a third lumen defined by a first conduit disposed within the first portion of the inner volume to define an extended lumen, wherein the third lumen is in fluid communication with a second portion of the inner volume defined by the housing that is fluidically isolated from the first portion of the inner volume, wherein a proximal end portion of the second cannula is operatively coupled to a fluid source;
- inserting at least a portion of the housing defining a first plurality of openings in fluid communication with the first portion of the inner volume and a second plurality of openings in fluid communication with the second portion of the inner volume into a body cavity such that each of the first plurality of openings and the second plurality of openings is disposed within the body cavity;
- conveying a fluid from the fluid source to the body cavity via the extended lumen, the second portion of the inner volume, and the second plurality of openings;
- and
- withdrawing at least a portion of the fluid from the body cavity into the vacuum source, substantially concurrently with conveying the fluid, via the first plurality of openings, the first portion of the inner volume, and the first lumen.
