The Penumbra System ACE 64 and ACE 68 were cleared by the FDA via the 510(k) pathway on January 13, 2016. Manufactured by Penumbra, these devices are classified as Class 2 under product code NRY.
What It Is
The Penumbra System ACE 64 and ACE 68 are reperfusion catheters designed for mechanical thrombectomy procedures. They are used to remove thrombi from blood vessels, particularly in venous applications, to restore blood flow.
Clinical Applications
These catheters are commonly used in clinical scenarios involving acute ischemic stroke where rapid restoration of blood flow is critical. They are particularly useful in patients with large vessel occlusions.
Evidence Summary
The available literature includes two studies, one from 2021 and another from 2024, focusing on the long-term effects and adjunctive use of fibrinolytics in mechanical thrombectomy. Study types include systematic reviews and meta-analyses.
Reported Outcomes
Published studies report that mechanical thrombectomy using the Penumbra System ACE catheters can improve long-term outcomes in stroke patients, particularly those with large ischemic cores. The adjunctive use of intra-arterial fibrinolytics may enhance reperfusion efficacy.
Safety Profile
Reported complications include sparse data on the safety of adjunctive intra-arterial fibrinolytics. The studies highlight the need for further investigation into potential adverse events associated with these adjunctive therapies.
Evidence Limitations
The evidence is limited by the scarcity of data on long-term outcomes and safety of adjunctive therapies. Further research is needed to establish comprehensive safety profiles and efficacy in diverse patient populations.
