A method for capturing dislodged vegetative growth during a surgical procedure is provided. The method includes maneuvering, into a circulatory system, a first cannula having a distal end and an opposing proximal end, such that the first cannula is positioned to capture the vegetative growth en bloc. A second cannula is positioned in fluid communication with the first cannula, such that a distal end of the second cannula is situated in spaced relation to the distal end of the first cannula. A suction force is provided through the distal end of the first cannula so as to capture the vegetative growth. Fluid removed by the suction force is reinfused through the distal end of the second cannula. Subsequent to becoming dislodged, the vegetative growth is captured by the first cannula. A method for capturing a vegetative growth during removal of a pacemaker lead is also provided.

A clot removal system comprises a catheter, a vacuum source, and a controller. The catheter comprises a proximal end, a distal end, and controller operating parameters and defines a lumen configured to be filled with a liquid column having a proximal portion. The vacuum source is configured to supply vacuum. The controller is configured to carry out a control pattern of turning on and off the vacuum based upon the controller operating parameters and is configured to receive the controller operating parameters in an automatic response to the catheter being operatively connected to at least one of the vacuum source and the controller and, responsive to the connection, to carry out the control pattern to change a level of vacuum at the distal end of the catheter.

The apparatus pre-treats fluid and then delivers it to a patient during surgery, for example a hyperthermic intra-peritoneal chemotherapy (HIPEC) procedure. It comprises a reservoir (2) for the fluid, a reversible pump (10) and a valve assembly (22). In a recirculation mode, the pump (10) is operated in one direction to draw fluid from the reservoir (2), through the valve assembly (22) and back to the reservoir (2), while the fluid is pre-treated by heating, for example. In a fluid delivery mode, the pump (10) is operated in an opposite direction to draw fluid from the reservoir (2) and deliver the fluid through the valve assembly (22) to a port (30) from which it can be supplied to the patient. A second pump (12) may be provided for drawing fluid from the patient via a return port (48). The pumps (10,12) may be peristaltic pumps integrated with the walls of the reservoir (2).

A waste collection system for collecting medical/surgical waste. A mobile rover includes at least one waste container supported on the mobile rover for storing the medical/surgical waste. A chassis is separate from and configured be removably coupled with the mobile rover. The chassis supports a chassis controller and a vacuum pump configured to draw a vacuum on the waste container. A rover controller is supported on the mobile rover and configured to receive a pressure signal representative of a level of the vacuum. The chassis controller is configured to be in communication with the rover controller and to regulate the level of the vacuum drawn based on the pressure signal. A transmitter may be supported on the mobile rover and in communication with the rover controller, and a receiver may be supported on the chassis to be in communication with the transmitter to establish a communication circuit for data transfer.

Systems and methods for the intravascular treatment of clot material within a blood vessel of a human patient are disclosed herein. A method in accordance with embodiments of the present technology can include, for example, positioning a distal portion of a catheter proximate to the clot material within the blood vessel. The method can further include coupling a pressure source to the catheter via a tubing subsystem including a valve or other fluid control device and, while the valve is closed, activating the pressure source to charge a vacuum. The valve can then be opened to apply the vacuum to the catheter to thereby aspirate at least a portion of the clot material from the blood vessel and into the catheter.

Embodiments of the present disclosure provide an apparatus and method for evacuation. An exemplary apparatus includes a trocar comprising an inlet at a distal end and an exit port at a proximal end, the inlet and the exit port are fluidly connected by a tubular hollow body circumscribing a cavity extending through a longitudinal axis of the trocar, the trocar includes a filter maintained within the cavity operable to filter at least one of fluid and particulates from a flow passing through the cavity. The apparatus further includes a vacuum source fluidly connected to the exit port, the vacuum source operable to pull at least one of fluid and particulates through the inlet, the cavity and the exit port.
