Abstract
At least some embodiments of the present disclosure are directed to systems and methods for creating a shunt in a patient. In some embodiments, a shunting catheter includes: a catheter shaft having a distal end and a proximal end, the catheter shaft including a shaft lumen; a shunting component including one or more electrodes; and a puncture assembly disposed in the shaft lumen at a first state and extended from the catheter shaft at a second state.
Claims21
A shunting catheter, comprising:
- a catheter shaft having a distal end and a proximal end, the catheter shaft including a shaft lumen;
- a shunting component including one or more electrodes;
- and
- a puncture assembly disposed in the shaft lumen at a first state and extended from the catheter shaft at a second state;
- wherein the puncture assembly is connected to the shunting component;
- a shunting element shaft configured to support the shunting component, the shunting element shaft disposed in the shaft lumen at a first state and extended from the catheter shaft at a second state;
- wherein the puncture assembly comprises a puncture element and a dilator portion, the puncture assembly is disposed at a distal end of the shunting element shaft and configured to deliver a first ablation energy to create an opening at the second state;
- wherein at the second state:
- the shunting element shaft includes a curved portion and a straight portion when the shunting element shaft extends out of the catheter shaft;
- the puncture assembly is disposed proximate to the straight portion of the shunting element shaft;
- a tip of the puncture element defines a first axis;
- the straight portion of the shunting element shaft defines a second axis;
- the first axis and the second axis form an angle greater than zero degrees;
- and
- the dilator portion is disposed between the tip of the puncture element and the shunting component supported by the straight portion of the shunting element shaft;
- wherein the shunting component is configured to extend from the catheter shaft at a third state;
- wherein the one or more electrodes are configured to deliver a second ablation energy to enlarge the opening at the third state after delivery of the first ablation energy;
- wherein the second state is different from the third state.
