Post-market Clinical Follow-up Study on the Performance and Safety of a Vent Catheter Used During Cardiopulmonary Bypass.
Prior to the implementation of the Medical Device Regulation (MDR), the clinical evaluation of existing devices was conducted by Notified Bodies (NBs) based on clinical data obtained from equivalent devices, and CE certificates were issued for devices exhibiting similar characteristics. Following the transition to the MDR, the European Commission's Guidance Document MEDDEV 2.12/2 highlighted that Notified Bodies, which issued CE certificates under the previous regime, must now organize Post-Marketing Clinical Follow-up (PMCF) studies to verify the performance and safety of the device in accordance with its intended use throughout its lifecycle. Consequently, PMCF studies are being planned to demonstrate that medical devices previously marked with the CE mark under the old regulations are used safely for patients throughout their lifecycle.
Primary Objective To demonstrate the performance of the Bıçakcılar Vent Catheter in patients for whom its use is planned, in accordance with the device's intended purpose as outlined in the user manual, taking into account the following aspects: bleeding, trauma, passage manipulation, insertion and removal, compliance with the intended use, occlusion, retention of debris, effective use, and maintenance of its form

Primary Endpoints The primary endpoints have been designed to encompass all clinical outcomes that characterize the device's performance. The evaluation items listed below, which are directly related to the Bıçakcılar Vent Catheter, will be measured using a Likert scale with values ranging from 1 to 5.
- Presence of bleeding
- Impact of trauma
- Manipulation during insertion
- Placement
- Removal (including removal of the stylet, if applicable)
- Conformity to intended use/Drainage capability
- Blockage formation in the ports
- Presence of residue
- Effective use
- Retention of shape
Secondary Endpoints Since factors such as the surgeon performing the operation, the perfusionist operating the heart-lung machine, and the patients' clinical characteristics may act as confounding variables, other variables affecting the primary endpoints will be identified through secondary endpoints.
- General and demographic information
- Concomitant diseases
- Concomitant treatments
- Biochemical findings
- Echocardiographic findings
- Total duration of the procedure
- Type of procedure
- Vital and cardiac assessments
- Evaluations related to the Vent catheter
- Perfusion evaluations
- Cardioplegia evaluations
- Data on adverse events and complications
Definition of Participants (Volunteers) / Study Population Patients for whom a decision has been made by their physician to undergo routine surgical procedures using cardiopulmonary bypass, and for whom the use of a vent catheter is planned during the procedure
