Abstract
A medical device system may include a catheter sheath and a catheter shaft sized for delivery through a lumen of the catheter sheath. The catheter shaft may be coupled to an end effector at or adjacent a distal end of the catheter shaft. The catheter shaft may include a lumen and a control element. The control element may be coupled to the end effector and may reside within the lumen of the catheter shaft. Physical access may be provided to the control element, to allow the control element to be severed to facilitate removal of the end effector from a bodily cavity. The control element may include a lumen and a control cable therein. A liquid entry port may be provided in the lumen of the control element toward a distal end of the control element to allow expedited provision of fluid to a distal portion of the control element.
