The objective of this study is to demonstrate reasonable assurance that the Ringer catheter can be safely used to manage hemorrhage due to coronary vessel perforations while facilitating distal perfusion under the conditions of use prescribed in the labeling.
A prospective, multicenter, single-arm clinical study. The study will be conducted at up to 15 investigational sites in the US and will enroll up to 30 participants. The population for this investigation is adult participants who suffer a perforation of the coronary artery during a percutaneous coronary intervention requiring management of hemorrhage while providing distal perfusion until definite treatment is determined. This clinical investigation is being conducted under Exception from Informed Consent (EFIC) regulations because there is no reasonable way to identify patients likely to become eligible for the investigation, and a coronary perforation can be a life-threatening emergency that needs to be immediately controlled without enough time for the patient or their legally authorized representative to give consent. Patients will be notified of their enrollment as soon as feasible. For more information on the exception from informed consent, please use the contact information be.ow.

Effectiveness of device success in managing hemorrhage while preserving flow
Effectiveness of device success in managing hemorrhage while preserving flow via angiographic confirmation of: a) successful delivery of Ringer across perforation, b) acute cessation of extravasation while Ringer is inflated, and c) demonstration of antegrade blood flow during Ringer deployment.
Time frame: Procedure
Rate of Ringer related thrombosis and/or dissection
Rate of Ringer-related thrombosis and new or worsening coronary dissection following Ringer deflation and withdrawal.
Time frame: Procedure
Change in TIMI (thrombolysis in myocardial infarction) flow
The change in TIMI flow during Ringer deployment.
Time frame: Procedure
Change in perforation classification
The change in perforation classification after Ringer deployment
Time frame: Procedure
Rate of clinically relevant events
Rate of clinically relevant events in the management of the coronary perforation and any potential sequelae including: chest pain, bleeding incidence and severity, major adverse cardiac events (MACE), cardiac tamponade and pericardiocentesis, emergency surgery post-perforation including coronary artery bypass graft (CABG), death.
Time frame: Discharge or 30 days, whichever comes first.
