Event Description
|
It was reported that balloon rupture and tip detachment occurred.
The chronic totally occluded (cto) target lesion was located in the calcified proximal left anterior descending (lad) artery.
A 3.
00 mm x 15 mm nc emerge® balloon catheter was advanced for dilation.
After the balloon was inflated to 30 atmospheres, the balloon ruptured and separated into two pieces.
The distal tip of the balloon was left in the proximal lad and no attempt was made to retrieve the detached fragment.
The procedure was completed with another nc emerge balloon catheter.
No further patient complications were reported and the patient's status was fine.
The patient is scheduled for further rotational atherectomy on the cto at a later date.

Manufacturer Narrative

Device evaluated by mfr.
: returned product consisted of a nc emerge balloon catheter.
There was contrast and blood in the lumen.
The balloon, shaft and tip were examined.
Examination of the balloon revealed a complete circumferential tear with scratches on the balloon material.
Microscopic examination presented no irregularities in the balloon material that could have contributed to the damage.
The shaft was separated at the bi-component weld.
The inner separation was jagged, which indicates that the separation was due to tensile overload.
The distal end of the device was not returned for analysis.
Inspection of the remainder of the device, apart from the observed damage, revealed no other damage or irregularities.
No other issues were identified during the product analysis.
The investigation conclusion is user / use error as there was an act or omission of an act that resulted in a different medical device response than intended by the manufacturer or expected by the user.
The nc emerge dfu includes the following indication for use: "do not exceed the rated balloon burst pressure.
¿ the balloon compliance chart in table 2 within the dfu lists 20 atm as the rated burst pressure for 3.
00mm diameter devices.
