Dual-flow biological fluid exchange device

A fluid-exchange system for a medical procedure, comprising:

• a dual-flow body, comprising:
• a first fluid passage formed in the dual-flow body and defined at least in part by a first fluid outlet of the dual-flow body;
• and
• a second fluid passage formed in the dual-flow body and defined at least in part by a second fluid inlet of the dual-flow body;
• a first needle connected to the first fluid outlet of the dual-flow body;
• a second needle connected to the second fluid inlet of the dual-flow body;
• a first fluid reservoir connected to the dual-flow body and in fluid communication with the first fluid passage;
• and
• a second fluid reservoir connected to the dual-flow body and in fluid communication with the second fluid passage;
• wherein the first fluid reservoir is oriented at an angle with respect to the second fluid reservoir;
• wherein a second flow path extends from the second needle, through the second fluid passage, and into the second fluid reservoir, and a first flow path extends from the first fluid reservoir, through the first fluid passage, and out of the first needle.

A method of performing a medical procedure, comprising:

• positioning a fluid-exchange device at a surgical site, the fluid-exchange device including a first needle and a second needle each connected to and extending from a dual-flow body;
• penetrating the surgical site with the first needle and with the second needle such that the first needle and the second needle are in fluid communication with an anatomical fluid at the surgical site;
• withdrawing a portion of the anatomical fluid from the surgical site through the second needle via a second flow path extending from the second needle, through the dual-flow body, and into a second fluid reservoir connected to the dual-flow body;
• and
• while withdrawing the portion of the anatomical fluid, administering a replacement fluid to the surgical site through the first needle via a first flow path extending from a first fluid reservoir connected to the dual-flow body, through the dual-flow body, and out of the first needle.
