Abstract
According to one aspect of the present disclosure, a medical device may include a shaft assembly. The shaft assembly may include a sheath having a first lumen. The shaft assembly may also include a rotatable shaft extending through the first lumen. The rotatable shaft may be rotatable relative to the sheath, and may have a second lumen and a side opening. The shaft assembly may also include an electrode extending through the second lumen and the side opening, and radially outwardly from the rotatable shaft. The electrode may be movable relative to the rotatable shaft.
Claims15
A medical device, comprising:
- a shaft assembly, including:
- a sheath having a first lumen, and a distal section having a distal opening and a side opening;
- a rotatable shaft extending through the first lumen, the rotatable shaft being rotatable relative to the sheath and having a second lumen, a side opening, and a distal section extendable distally from the distal opening of the sheath;
- and
- an electrode extending through the second lumen of the rotatable shaft, the side opening of the rotatable shaft, and radially outwardly from the rotatable shaft, the electrode being movable relative to the rotatable shaft.
A medical device, comprising:
- a shaft assembly, including:
