Abstract
A cannister system for containing a catheter, the cannister including a drive mechanism for driving the catheter from the cannister and into a luminal network of a patient, the cannister including an entrance point for insertion of a tool into the catheter.
Claims20
A system for navigation of a lung comprising:
- an electromagnetic (EM) field generator;
- a sensor located on a distal end of a catheter, the sensor configured to receive EM signals and transmit them to a locating module;
- a computing device in communication with the locating module and configured to display a 3D model of the lungs and to depict the location of the catheter in the 3D model;
- a cannister configured to retain the catheter in a coiled form within the cannister, the cannister having an entrance point centrally located on a top surface of the cannister and an exit point centrally located on a bottom surface of the cannister;
- an arm configured to support the cannister;
- a drive mechanism configured to advance the catheter from the cannister through the exit point and into the lungs of a patient, the drive mechanism including a pair of driven wheels, the pair of driven wheels contacting opposite sides of the catheter and configured to act on an exterior surface of the catheter;
- and
- a first articulation motor mechanically coupled to a first pair of pull-wires, the first pair of pull wires being retained within a first pair of lumens formed in the catheter, wherein actuation of the articulation motor results in articulation of a distal end of the catheter in at least one direction.

A catheter system for use with a luminal navigation system comprising:
- a cannister configured to retain a catheter in a coiled form, the cannister having an entrance point and an exit point;
- a drive mechanism including a pair of drive wheels, the pair of driven wheels contacting opposite sides of the catheter and configured to advance the catheter from the cannister through the exit point and into a luminal network of a patient;
- and
- an articulation motor mechanically coupled to a pair of pull-wires, the pull wires being retained within lumens formed in the catheter, wherein actuation of the articulation motor results in articulation of a distal end of the catheter in at least one direction.
1 more element
A catheter system for use with a luminal navigation system comprising:
- a first cannister having an entrance point and an exit point;
- a disposable catheter configured for receipt and retention in the first cannister in a coiled form;
- a second cannister having an entrance point and an exit point;
- a flexible disposable tool configured for receipt and retention in the second cannister in a coiled form;
- a drive mechanism in the first cannister including a pair of driven wheels, the pair of driven wheels contacting opposite sides of the catheter and configured to advance the catheter from the first cannister through the exit point in the first cannister and into a luminal network of a patient;
- a drive mechanism in the second cannister configured to advance the tool through the exit point in the second cannister and into the entrance point of the first cannister and into a lumen in the disposable catheter;
- and
- an articulation motor mechanically coupled to a pair of pull-wires, the pull wires being retained within lumens formed in the disposable catheter, wherein actuation of the articulation motor results in articulation of a distal end of the catheter in at least one direction.
