A medical device, comprising:
- a valve housing extending from a proximal end adapted for coupling to a fluid source to a distal end adapted for coupling to a fluid delivery device, the valve housing comprising:
- a first branching portion having a single proximal fluid channel at a proximal aspect, the single proximal fluid channel being divided into a plurality of intermediate fluid channels at a distal aspect of the first branching portion;
- a second branching portion having the plurality of intermediate fluid channels at a proximal aspect, the plurality of intermediate fluid channels extending into a plurality of intermediate fluid channels of the second branching portion which then merge into a single distal fluid channel at a distal aspect of the second branching portion;
- and a plurality of valve elements, each valve element disposed within each of the plurality of intermediate fluid channels;
- wherein each valve element includes a flexible elastomeric membrane having at least one slit therethrough.
