Event Description
|
It was reported to boston scientific corporation that a sensation short throw was used during a colonoscopy procedure performed on (b)(6) 2021.According to the complainant, during the procedure, the 27mm snare was being used to remove a pedunculate polyp and when the snare was in place the snare wouldn't close and wouldn't conduct energy to cut.This caused the snare to become logged in the polyp and had to be cut at the handle to be removed.The procedure was completed with another sensation short throw and the polyp was removed in piece meal sections.There were no patient complications reported as a result of this event.The patient's condition at the conclusion of the procedure was reported to be fine.

Manufacturer Narrative

Block h6: problem code a150208 captures the reportable event of loop entrapment.Block h10: the returned sensation short throw was analyzed, and a visual evaluation noted that the device was returned with the working length and wire cut off.The wire was found exiting the working length and both components (wire and working length) were noted kinked.The reported issues of failure to deliver energy, loop retraction problem, and loop entrapment of device or device component could not be confirmed since the devices cannot be functionally evaluated with respect to anatomical/procedural factors encountered during the procedure.Additionally, the device was returned with the sheath and wire cut off making it impossible to perform any test.It was reported that the snare was embedded in the polyp and intervention was required.Upon device analysis it was noted that the working length and wire were cut off which match with the reported complaint that states that the device was cut.Also, the wire and working length were noted kinked.The user may have applied excessive force trying to remove the device from the polyp resulting in the device damaged.The product record review confirmed that this is not a new failure type and the risk is anticipated.There is no evidence of a manufacturing issue, design or user issue which could have caused the complaint.Based on the information available and the analysis of the returned device, this investigation has been assigned the most probable conclusion code of adverse event related to procedure.This is defined as a complaint where an adverse event occurred during the procedure and the device had no influence on the event.A review of the manufacturing documentation for this device revealed that no anomalies or deviations related to the event occurred during manufacturing.
