Abstract
A fluid management system for use in a tissue resection procedure includes a controller. An inflow pump is operated by the controller and configured to provide fluid inflow through a flow path to a site in patient's body. An outflow pump is operated by the controller and configured to provide fluid outflow through a flow path from the site in patient's body. A motor driven resecting device may be provided for resecting tissue at the site. The controller is configured to actuate an inflow pump and an outflow pump in response to various signals and various algorithms are provided to provide malfunction warnings and assure safe operation.
Claims18
A fluid management system for a medical device, comprising:
- a controller;
- and
- a pump operated by the controller and adapted to provide a fluid flow at a target site;
- and
- a controller algorithm configured to monitor a measured electrical current supplied to a motor driving the pump;
- wherein the controller algorithm is adapted to automatically deactivate the pump to interrupt a medical procedure at the target site if the measured electrical current exceeds a predetermined level for a pre-selected time interval.
A method of controlling a fluid management system, comprising:
- providing a fluid flow to a target site with a pump operated by a controller;
- monitoring a measured electrical current supplied to a motor driving the pump using a controller algorithm;
- and
- automatically deactivating the pump to interrupt a medical procedure at the target site if the measured electrical current exceeds a predetermined level for a pre-selected time interval.
