It was reported that the procedure was to treat a de novo lesion in the non-tortuous, non-calcified, mid left anterior descending (lad) coronary artery.
A 3.
50 x 15 mm nc trek rx balloon dilatation catheter (bdc) was selected for the procedure.
The bdc was advanced to the lesion with no resistance felt and on the first inflation attempt the balloon did not inflate as evidenced by contrast medium not filling the balloon.
The bdc was removed for the anatomy and another inflation attempt was tried and the balloon still did not inflate.
A non-abbott bdc was used to successfully complete the procedure.
There was no reported clinically significant delay in the procedure.
There was no reported adverse patient sequela.
No additional information was provided.

(b)(4).
Evaluation summary: the device returned for analysis.
The complaint investigation determined the reported difficulty was related to manufacturing issues associated with the protective sheath.
On march 14, 2017, abbott vascular decided to initiate a voluntary field action for some sizes and lots of the nc trek family of dilatation catheters for difficulty to remove sheath which may lead to inflation or deflation issues.
Abbott vascular performed a comprehensive investigation which included device analysis, manufacturing evaluation and trend analysis.
The root cause identification was complicated by the fact that users were describing multiple symptoms when reporting the complaints.
To date, the frequency of worldwide reported events for difficulties removing the protective balloon sheath, inflation and deflation has reached an actionable limit, thus abbott vascular communicated the voluntary field action to the fda on march 17, 2017 [medwatch # 2024168-2017-02310].
Corrective action has been implemented per site operating procedures.
The product will continue to be trended.
The abbott internal recall number is 2024168-3/14/2017-002-r.
