Description of event according to clinical study: two registrars were placing the filter in question under the watch of the physician as part of our clinical study.This was done from a right femoral approach, all went well right up to the placement.The filter was in a great position, as the filter was deployed the secondary legs deployed as they should but when it came to the primary legs it appeared that the radiopaque marker at the end of the deployment system was stopping this from happening.After a few attempts to deploy the feet and losing position a number of times the filter had to be deployed in the delivery system and the doctors used the dilator and another catheter to then push the filter out.The filter was deployed but due to the way this had to be done is now tilted, but is doing its job.Patient outcome: the patient did not require any additional procedures due to this occurrence.According to the initial reporter, the patient did not experience any adverse effects due to this occurrence.
