Abstract
A surgical fluid management system delivers fluid for distending a uterine cavity to allow cutting and extraction of uterine fibroid tissue, polyps and other abnormal uterine tissue. The system comprises a fluid source, fluid deliver lines, one or more pumps, and a filter for re-circulating the distension fluid between the source and the uterine cavity. A controller can monitor fluid retention by the patient.
Claims20
A medical fluid management system, comprising:
- a fluid reservoir having an initial volume;
- a filter system having a fluid retention volume;
- a first fluid line configured to carry a fluid from the fluid reservoir through the first fluid line to a body cavity, the first fluid line having a fluid retention volume;
- a second fluid line configured to carry the fluid from the body cavity through the second fluid line to the filter system, the second fluid line having a fluid retention volume;
- and
- a third fluid line configured to carry the fluid from the filter system through the third fluid line back to the fluid reservoir, the third fluid line having a fluid retention volume;
- wherein the initial volume of the fluid reservoir minus a sum of the fluid retention volumes of the filter system and the first, second and third fluid lines equals 2.5 liters or less.

A medical fluid management system, comprising:
- a fluid reservoir having an initial volume;
- a filter system having a fluid retention volume, the filter system including a tissue capturing filter and a molecular filter;
- a check valve fluidly coupled between the tissue capturing filter and the molecular filter;
- a first fluid line configured to carry a fluid from the fluid reservoir through the first fluid line to a body cavity, the first fluid line having a fluid retention volume;
- and
- a second fluid line configured to carry the fluid from the body cavity through the second fluid line to the filter system, the second fluid line having a fluid retention volume;
- and
- a third fluid line configured to carry the fluid from the filter system through the third fluid line back to the fluid reservoir, the third fluid line having a fluid retention volume;
- wherein the tissue capturing filter is configured to catch resected tissue;
- wherein the molecular filter is configured to filter out red blood cells.
