Systems and methods for directing valves that control a vacuum applied to a patient
First Claim
1. A method for controlling vacuum drawn on a patient during a medical procedure, comprising:
- receiving a first input to apply vacuum to an orifice of a device positioned within a patient;
in response to the first input, automatically directing a first valve coupled between the orifice and a vacuum source to move from a closed state to an open state;
receiving a second input to cease applying the vacuum to the orifice; and
in response to the second input;
automatically directing the first valve to move from the open state to the closed state;
automatically directing a second valve coupled between the orifice and atmospheric pressure to move from a closed state to an open state; and
automatically directing the second valve to move back from the open state to the closed state.

Abstract
Systems and methods for directing valves that control a vacuum applied to a patient are disclosed. A method in accordance with one embodiment includes receiving a first input to apply vacuum to an orifice of a device positioned within a patient, and in response to the first input, automatically directing a first valve coupled between the orifice and a vacuum source to move from a closed state to an open state. The method can further include receiving a second input to cease applying the vacuum to the orifice, and in response to the second input, automatically directing the first valve to move from the open state to the closed state, automatically directing a second valve coupled between the orifice and atmospheric pressure to move from a closed state to an open state, and automatically directing the second valve to move back from the open state to the closed state.

13. A method for controlling a procedure for sealing a patent foramen ovale, comprising:
-
receiving a first vacuum input to apply vacuum to an orifice of a catheter device positioned within a patient'"'"'s heart;
in response to the first vacuum input, automatically directing a first valve coupled between the orifice and a vacuum source to move from a closed state to an open state;
directing the application of energy to tissue at least proximate to the patent foramen ovale to seal the patent foramen ovale;
directing the application of energy to the tissue to cease;
receiving a second vacuum input to cease applying the vacuum to the orifice; and
in response to the second vacuum input;
automatically directing the first valve to move from the open state to the closed state;
automatically directing a second valve coupled between the orifice and atmospheric pressure to move from a closed state to an open state to increase a pressure at the orifice at least toward atmospheric pressure; and
automatically directing the second valve to move from the open state to the closed state after the second valve has been in the open state for a predetermined period of time. - View Dependent Claims (14, 15)

16. A system for controlling a vacuum drawn on a patient during a medical procedure, comprising:
-
a first valve automatically changeable between an open state and a closed state, the first valve being coupleable between a vacuum source and a patient device having an orifice positioned to be placed inside a patient;
a second valve automatically changeable between an open state and a closed state, the second valve being coupleable between the orifice and atmospheric pressure;
an input device; and
a controller operatively coupled to the first valve, the second valve, and the input device, the controller being configured to;
receive a first input to apply vacuum to the orifice;
in response to the first input, automatically direct the first valve to move from the closed state to the open state;
receive a second input to cease applying the vacuum to the orifice; and
in response to the second input;
automatically direct the first valve to move from the open state to the closed state;
automatically direct the second valve to move from the closed state to the open state; and
automatically direct the second valve to move back from the open state to the closed state. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25)
