Abstract
Devices, systems, and methods for therapeutically treating tissue. The devices and methods are suitable for minimally invasive surgery or open surgical procedures. More particularly, methods and devices described herein permit accessing and/or treating areas of tissue with a therapeutic device.
Claims9
A medical device for accessing a region of tissue, the device comprising:
- a shaft having a distal end and a proximal end with a passage extending there-through, the shaft having a distal section adjacent to the distal end and a flexible section being proximally spaced from the distal section;
- a handle located at the proximal end, the handle having an actuator and a locking mechanism on the handle, wherein the actuator and locking mechanism are rotatable along the same axis;
- a steering member coupled between the actuator and the distal section of the shaft, such that movement of the actuator controls a deflection of the distal section, where the deflection of the distal section is limited to a first plane, wherein the locking mechanism secures the distal section of the shaft in an arcuate shape by setting the actuator;
- a dilator extending through the shaft, the dilator having an atraumatic tip extending through the distal end of the shaft, the dilator further including a locking hub that engages with a proximal end of the handle and is configured to removably lock with the handle;
- and
- wherein the proximal section of the shaft is flexible and limited to bend in a second plane, where the second plane is perpendicular to the first plane.

A surgical device adapted to be coupled to a vacuum source and for coagulating soft tissue and for use with an electroanatomic mapping system, the surgical device comprising:
- an elongate member comprising a side wall and a lumen, where the lumen is fluidly coupleable to the vacuum source;
- a tissue heating element adjacent the side wall within the elongate member;
- and an opening through the side wall in communication with the lumen and exposing the tissue heating element where the tissue heating element is positioned within the opening such that when placed against tissue, the tissue heating element coagulates soft tissue at the opening;
- and
- at least a first navigation element located on the elongate member, where the first navigation element is configured to produce a first virtual image that represents at least a portion of the elongate member in the electroanatomic mapping system, at least a second navigation element configured to produce a second virtual image that represents an orientation of the opening in the sidewall exposing the element relative to the housing.
