Removal of errant coils using the Tigertriever-13
Bibliographic record
Abstract
Coil migration poses a significant intraprocedural risk during coil embolization in interventional neuroradiology procedures. In this technical video we describe the technique of removal of errand coils using the low profile Tigertriever-13 device.1 Traditional methods of errant coil retrieval rely on the use of stent retrievers;2 however, these devices are usually too large to fit through smaller inner diameter 0.013-0.0165 inch coiling catheters, thus requiring upsizing materials in emergency situations.3 We demonstrate the technique of coil retrieval using this low-profile device ex-vivo in silicone flow models, then its application in vivo as a 'bail-out' technique during acute embolization of a ruptured peri-callosal aneurysm which required retrieval of errant coils (video 1). neurintsurg;16/12/1212/V1F1V1Video 1Errant coil retrieval using the Tigertriever device.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
