Systems and methods for removing undesirable material within a circulatory system during a surgical procedure
First Claim
1. A method for capturing dislodged vegetative growth during a surgical procedure, the method comprising:
- maneuvering, within a circulatory system, a first cannula such that its distal end is positioned in a strategic location for subsequent capture of a vegetative growth that has become dislodged during the surgical procedure;
positioning, within the circulatory system, a second cannula, in fluid communication with the first cannula, such that a distal end of the second cannula is in a spaced relation to the distal end of the first cannula;
providing a pump capable of simultaneously creating a suction force and a driving force, the suction force is through the distal end of the first cannula so as to capture any vegetative growth that has become dislodged and the driving force is through the distal end of the second cannula; and
performing the surgical procedure.

Abstract
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 caputred by the first cannula. A method for capturing a vegetative growth during removal of a pacemaker lead is also provided.

24. A method for capturing dislodged undesirable material during an interventional procedure, the method comprising:
-
maneuvering, within a circulatory system, a first cannula such that its distal end is positioned in a strategic location for subsequent capture of an undesirable material that has become dislodged during the interventional procedure; positioning, within the circulatory system, a second cannula, in fluid communication with the first cannula, such that a distal end of the second cannula is in a spaced relation to the distal end of the first cannula; providing a pump capable of simultaneously creating a suction force and a driving force, the suction force is through the distal end of the first cannula so as to capture any undesirable material that has become dislodged and the driving force is through the distal end of the second cannula; and performing the interventional procedure. - View Dependent Claims (25, 26)
