Event Description
|
It was reported that balloon deflation issues occurred.A 3.50 x 12mmpromus premier select stent balloon expandable was advanced for treatment.During the procedure a 3.50 x 12mmpromus premier select stent was implanted.Following implantation, the delivery balloon was attempted to be deflated, however the balloon did not fully deflate.It was not possible to pull the balloon back in the 6fr guiding catheter.The catheter, wire and balloon were retrieved, and the procedure was completed successfully.There were no patient complications reported.

Manufacturer Narrative

Device evaluated by manufacturer: the returned product consisted of the promus premier select stent delivery system (sds), batch #31542256.Visual, tactile, microscopic and functional analysis was performed on the device.Multiple kinks were noted along the hypotube shaft.Microscopic examination of the distal extrusion found that the inner/wire lumen was bunched at 5.5cm proximal from the tip of the device.In functional analysis, the device was attached to an encore inflation unit and the balloon was inflated to its rated burst pressure of 16 atmospheres with no leaks noted.However, when the device was deflated it took 20 seconds for the balloon to deflate.This inflate/deflate was repeated three more times and each deflation took approximately 20 seconds.Device analysis identified that the balloon deflated above the maximum deflation time specification (is less than equal to 16 seconds per the ifu).The average deflation time for the balloon during device analysis was 20 seconds.One possibility for the balloon deflating above its recommended deflation time is the fact there was damage on the inner wire lumen.E1 initial reporter phone: (b)(6).B5 describe event or problem: updated.
