Can a Stent Retriever Damage the JET 7 Reperfusion Catheter?

Area of Science:

• Neurosurgery
• Interventional Neurology
• Medical Device Engineering

Background:

• Mechanical thrombectomy is a key treatment for acute ischemic stroke.
• Stent retrievers are commonly used devices for clot removal.
• Reperfusion catheters facilitate blood flow restoration post-thrombectomy.

Observation:

• Two incidents of JET 7 reperfusion catheter damage were observed.
• Damage occurred during mechanical thrombectomy procedures involving stent retrievers.
• Catheter failure manifested as distal fraying and ballooning upon saline flushing.

Findings:

• The JET 7 reperfusion catheter demonstrated susceptibility to mechanical failure.
• Damage was consistently observed after one to two passes with a stent retriever.
• The observed failure mode involved structural degradation of the catheter tip.

Implications:

• This mechanical failure in reperfusion catheters could lead to severe patient complications.
• Neurointerventionalists must be aware of this potential risk when using JET 7 catheters with stent retrievers.
• Further investigation into device integrity and procedural technique is warranted to ensure patient safety.
