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.
Claims20
An apparatus, comprising:
- a housing having a proximal end portion and a distal end portion and defining an inner volume, the housing defining a first plurality of openings in fluid communication with a first portion of the inner volume and a second plurality of openings in fluid communication with a second portion of the inner volume, the first portion of the inner volume being fluidically isolated from the second portion of the inner volume;
- a proximal seal member disposed at least partially within the housing, the proximal seal member having a first coupling portion and a second coupling portion;
- a first cannula having a proximal end portion and a distal end portion and defining a lumen therethrough, the proximal end portion of the first cannula configured to be placed in fluid communication with a vacuum source, the distal end portion of the first cannula coupled to a first opening of the first coupling portion of the proximal seal member such that the first portion of the inner volume and the lumen of the first cannula collectively define a fluid flow path between the first plurality of openings and the vacuum source;
- a second cannula having a proximal end portion and a distal end portion and defining a lumen therethrough, the proximal end portion of the second cannula configured to be placed in fluid communication with a fluid source, the distal end portion of the second cannula coupled to a first opening of the second coupling portion of the proximal seal member;
- a first conduit disposed within the inner volume and coupled to the first coupling portion of the proximal seal member, the first conduit defining a lumen configured to place the lumen of the first cannula in fluid communication with the first portion of the inner volume;
- a second conduit disposed within the inner volume coupled to the second coupling portion of the proximal seal member, the second conduit defining a lumen configured to place the lumen of the second cannula in fluid communication with the second portion of the inner volume, wherein a first end portion of the first conduit is in contact with an inner surface of the housing to collectively define a substantially fluid tight seal therebetween, and a first end portion of the second conduit is in contact with the inner surface of the housing to collectively define a substantially fluid tight seal therebetween, the first portion of the inner volume is defined between the first end portion of the first conduit and the first end portion of the second conduit;
- and
- an inner volume conduit disposed within the first portion of the inner volume, the inner volume conduit defining a lumen in fluid communication with the second portion of the inner volume and the lumen of the second cannula such that the second portion of the inner volume and the lumen of the inner volume conduit and the lumen of the second cannula collectively define a fluid flow path between the second plurality of openings and the fluid source.

- and
- an inner volume conduit disposed within the first portion of the inner volume, the inner volume conduit defining a third lumen in fluid communication with the second lumen and the second portion of the inner volume such that the second lumen and the third lumen define an extended lumen that is in fluid communication with the second portion of the inner volume and the fluid source.
