Abstract
A tissue displacement apparatus used during a tissue ablation procedure is provided. In some configurations, the tissue displacement apparatus is configured to displace tissue within a patient and thermally isolate the displaced tissue.
Claims18
A tissue displacement apparatus configured to be slideably received within an external tube configured to be placed within a patient's body, the tissue displacement apparatus comprising:
- a tube defining a central lumen and a distal end, the tube configured to be moveable between a first tube position where the distal end of the tube is arranged within the external tube and a second tube position where the distal end of the tube protrudes from the external tube;
- an expandable cage arranged on the distal end of the tube and expandable between a first cage position where the expandable cage is collapsed and a second cage position where the expandable cage is expanded;
- and
- wherein, when the tube is in the first tube position, the expandable cage is in the first cage position and wherein when the tube moves to the second tube position, the expandable cage expands to the second cage position.
A tissue displacement apparatus configured to be slideably received within an external tube configured to be placed within a patient's body, the tissue displacement apparatus comprising:
- a tube defining a central lumen, a distal end, and a proximal end, the tube configured to be moveable between a first tube position where the distal end of the tube is arranged within the external tube and a second tube position where the distal end of the tube protrudes from the external tube;
- an expandable cage arranged on the distal end of the tube and expandable between a first cage position where the expandable cage is collapsed and a second cage position where the expandable cage is expanded;
- and
- an actuation element arranged on the proximal end of the tube and including a push button, the push button configured to expand the expandable cage between the first cage position and the second cage position when actuated.
