Abstract
The present disclosure is directed to a medical instrument. The medical instrument may include a shaft having a distal end configured to cauterize tissue. An expandable member may be positioned adjacent the distal end of the shaft. The expandable member may be configured for deployment between a collapsed configuration and an expanded configuration.
Claims20
A medical instrument comprising:
- a shaft having a distal end configured to cauterize tissue;
- and
- an expandable member configured for insertion between a first tissue layer and a second tissue layer adjacent the first tissue layer, wherein the expandable member is configured to expand from a collapsed state to an expanded state to separate the first tissue layer from the second tissue layer, and wherein at least a portion of the expandable member has a substantially flat base in the expanded state.
A method of separating tissue layer, comprising:
- positioning a distal portion of a medical instrument, including a shaft having a distal end configured to cauterize tissue, and an expandable member adjacent the distal end of the shaft, adjacent a tissue site;
- inserting the distal portion between a first tissue layer and a second tissue layer at the tissue site;
- and
- expanding the expandable member from a collapsed configuration to an expanded configuration to separate the first tissue layer from the second tissue layer, wherein at least a portion of the expandable member has a wedge-shaped profile in the expanded configuration.

A tool comprising:
- a cap member having a proximal end and a distal end, wherein the proximal end is configured to be secured to a distal portion of an introduction sheath, and wherein at least one of the cap member or a portion of the cap member is transparent;
- a tip extending distally from the distal end of the cap member;
- and
- at least one expandable member secured to the cap member, wherein the expandable member is configured to transition between a collapsed state and an expanded state.
