Abstract
Methods and systems for administering directed fluidics during a medical procedure for removing an object are disclosed. A method includes inserting first and second medical instruments into a treatment site, providing irrigation and aspiration of the treatment site through the first and second medical instruments, determining a characteristic of one of the irrigation and the aspiration, and selecting a characteristic of the other of the irrigation and aspiration based on the determined characteristic.
Claims26
A method of administering fluidics during a medical procedure, the method comprising:
- inserting a first medical instrument percutaneously into a treatment site, the first medical instrument comprising a first fluid channel and a second fluid channel;
- advancing a second medical instrument through a patient lumen into the treatment site, the second medical instrument comprising a lithotripter;
- performing lithotripsy on an object within the treatment site with the lithotripter of the second medical instrument;
- providing irrigation into the treatment site through the first fluid channel of the first medical instrument;
- providing aspiration from the treatment site through the second fluid channel of the first medical instrument;
- determining a characteristic of one of the irrigation and the aspiration;
- and
- selecting a characteristic of the other of the irrigation and aspiration based on the determined characteristic.
A system for performing a medical procedure, the system comprising:
- a first medical instrument configured to be percutaneously inserted into a treatment site, the first instrument including a first fluid channel and a second fluid channel;
- a vacuum connected to one of the first fluid channel and the second fluid channel and configured to apply a negative pressure to provide aspiration from the treatment site;
- a pump coupled to an irrigation source and the other of the first fluid channel and the second fluid channel, the pump configured to provide irrigation to the treatment site;
- and
- a fluidics control system coupled to the vacuum and the pump, the fluidics control system comprising one or more processors configured to:
- determine a characteristic of one of the irrigation and the aspiration;
- and
- control a characteristic of at least one of the pump or the vacuum based on the determined characteristic;
- and
- a second medical instrument configured to be inserted through a patient lumen into the treatment site, the second medical instrument comprising a lithotripter configured to perform lithotripsy on an object within the treatment site.
A medical device comprising:
- an articulable elongate body extending along an axis to a distal end;
- a first fluid channel extending along the axis, the first fluid channel terminating in a first fluid orifice formed in a distal face of the distal end;
- at least one additional fluid channel formed through the elongate body, the at least one additional fluid channel terminating in at least one additional fluid exit orifice formed in a radial surface of the elongate body proximal the distal end;
- and
- a pocket comprising a recess formed in a distal face of the distal end of the articulable elongate body, the pocket configured to hold an object during a lithotripsy procedure.
