Functions: internal aortic occlusion, cardioplegia delivery, aortic root pressure monitoring. Operated by surgeons in OR. Combines functions of multiple predicate catheters into single device. Benefits: enables minimally invasive or specialized bypass procedures by replacing external mechanical clamps with internal balloon occlusion. ## Clinical Evidence Clinical investigation conducted on ten subjects. Primary endpoint: successful maintenance of cardiopulmonary bypass. Results demonstrated device functioned safely and met clinical requirements. ## Technological Characteristics Multi-lumen balloon catheter. Materials include latex. Functions: vascular occlusion, fluid delivery, pressure monitoring. Form factor: catheter-based. ## Regulatory Identification A vascular clamp is a surgical instrument used to occlude a blood vessel temporarily. ## Predicate Devices - Medi-tech Occlusion Balloon Catheter - RMI Coronary Sinus Perfusion & Pressure Monitoring Cannulae - Cooley Aortic Clamp - DLP Cardioplegia Pressure Cannula with Vent Line - Datascope PERCLUDER™ - DL Occluding Balloon - Fogarty Occluding Catheter ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

Tucker Phone Number: (415) 306-7900 Fax Number: (415) 306-7905 ### Device Information: Trade Name: Endoaortic Clamp Common Name: Endoaortic Clamp Catheter Classification Name: Cardiopulmonary bypass vascular catheter ### Equivalent Devices: Medi-tech Occlusion Balloon Catheter RMI Coronary Sinus Perfusion & Pressure Monitoring Cannulae Cooley Aortic Clamp DLP Cardioplegia Pressure Cannula with Vent Line Datascope PERCLUDER™ - DL Occluding Balloon Fogarty Occluding Catheter ### Predicate Device Descriptions: #### Medi-tech Balloon Occlusion Catheter This predicate is a pre-enactment device commercially distributed in multiple sizes. This device is a multi-lumen latex balloon catheter which occludes vasculature through one lumen, and delivers contrast material or therapeutic agents through the second lumen. #### The RMI Coronary Sinus Perfusion & Pressure Monitoring Cannula Heartport, Inc. Page 15 CONFIDENTIAL {1} Appendix E. 510(k) Summary Supplement I 510(k) 955132 The cannula is a post-enactment device distributed in multiple sizes. This device is a multi-lumen latex balloon cannula which occludes the coronary sinus, perfuses cardioplegia, and monitors pressure. ## Cooley Aortic Clamp This pre-enactment device is a stainless steel mechanical anastomosis clamp manufactured by Baxter Healthcare Corporation. The device is available in a variety of sizes, with varied jaw angles. It is intended to physically clamp the exterior of the aorta causing total occlusion. ## DLP Cardioplegia Pressure Cannula with Vent Line This post-enactment device is an aortic root cannula with a vent line manufactured by Medtronic, Inc.. The device is intended to deliver cardioplegia, monitor aortic root pressure, and provide venting. ## Datascope PERCLUDER™ - DL Occluding Balloon This post-enactment device is an occluding balloon manufactured by. Datascope. The device is indicated for use in internally occluding the aortic arch during cardio-pulmonary bypass grafting. ## Fogarty Occluding Catheter This pre-enactment device is an occluding balloon catheter manufactured by Baxter Healthcare. This device is indicated for use in internally occluding the aorta and delivering chemotherapeutic agents. ## Intended Use: Occlusion of the aorta, delivery of cardioplegia, and monitoring of aortic root pressure during cardiopulmonary bypass. ## Comparison To Predicate Devices: This device combines the same functions as the individual predicate devices, into a single catheter. ## Clinical Test Results: The Heartport Endoaortic Clamp Catheter successfully maintained cardiopulmonary pass in ten subjects of a clinical investigation. ## Test Conclusions: Performance testing has demonstrated that the Endoaortic Clamp will function safely and efficaciously, while meeting the anticipated clinical requirements for the intended use.
