1. An apparatus, comprising:
a housing have 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 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 the housing 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; and 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 the housing such that the second portion of the inner volume and the lumen of the second cannula collectively define a fluid flow path between the second plurality of openings and the fluid source. |
