Abstract
A catheter device 10 with a cutting structure or means 16 on the distal portion 14 is disclosed, along with a medical procedure for using the device. The catheter 10 is configured in such a way as to create a permanent interatrial aperture in the heart, including creating a permanent interatrial hole and/or removing tissue.
Claims19
A medical device assembly comprising:
- a first delivery catheter comprising:
- an elongated delivery catheter shaft having a shaft lumen and a distal end,
- an RF cutter on the distal end, the RF cutter comprising an electrode and a cutter lumen,
- the RF electrode configured to cut a 3 mm or larger durable aperture in an interatrial septum,
- a proximal tissue retention device,
- a second delivery catheter comprising:
- a distal tissue retention device,
- an actuator, the actuator configured to change a relative position between the proximal and distal tissue retention devices.
