Lymphatic Injury Visualization in Vascular Surgery

This study aims to assess a simple intervention: Visualization of lymphatic injury + treatment (in case of detection). This will generate data on the incidence of intraoperative lymphatic injury and the effect of treatment. This data will then hopefully enable a multi-center RCT to generate high level evidence on this matter.

Targeting Real World Usage In Stroke Treatment

TRUST Registry is an observational, prospective, long-term, post-market surveillance registry of subjects treated with WallabyPhenox flow modulation devices, stent systems, bifurcation aneurysm implants including their HPC variants (Hydrophilic Polymer Coating) where applicable as well as coil systems, and other adjunctive medical devices. The overarching purpose of this registry is to carry out a proactive gathering, recording, and analysis of data on the safety, performance and usability of the devices as applied within the routine practice of the participating registry sites.

Evaluation of the GORE® Ascending Stent Graft

The primary objective of ARISE II is to assess the safety and effectiveness of the GORE® Ascending Stent Graft device in the treatment of lesions involving the ascending aorta and aortic arch.

Beacon Tip Sizing Catheter and Slip-Cath Beacon Tip Catheter Study

This prospective observational post-market clinical study will collect data in the United States to primarily support the re-launch of the re-designed Beacon Tip Sizing Catheter and Slip-Catheter Beacon Tip Catheter \& Shuttle Select Slip-Catheter (Visceral and Cerbral) for a Conformité Européenne (CE) Mark application in the European Union (EU). Additionally, the data from this study may be used to support regulatory approval in other countries/regions. The purpose of this clinical study is to evaluate the safety and performance of these catheters in accordance with the Intended Use through the end of index procedure, and through 30 days post procedure, (as applicable as data is available) to ensure an acceptable benefit:risk ratio.

Mechanical Complications of Acute Myocardial Infarction: a Multicenter Prospective Study

In 2019, the international study titled "CAUTION Study - 1" (MeChanical complicAtions of acUte myocardial infarcTion: an InternatiOnal multiceNter cohort study), a retrospective multicenter study, was launched and registered on ClinicalTrials.gov (Identifier: NCT03848429). This study highlighted the outcomes of surgical treatment of post-infarction mechanical complications in patients operated between 2000 and 2019. Several scientific publications have resulted from this registry, which involved 27 international centers and recruited about 800 patients. However, retrospective studies are inherently limited by factors such as selection bias and a high number of missing data, affecting data interpretation and consistency of results. Moreover, most registries report only data about surgical patients or, in rare situations, about patients treated percutaneously. To overcome these limitations, a prospective study has been designed to collect more precise and focused data and achieve results that better reflect the current clinical practice, including all the patients diagnosed with post-infarction mechanical complications, independently from the treatment assigned. "CAUTION Study - 2" is, therefore, a prospective, multicenter cohort study with the primary aim of analyzing the outcomes of surgical, percutaneous and conservative treatment of post-infarction mechanical complications in the contemporary era.

Feasibility of Endovascular Repair Of Ascending Aortic Pathologies

The purpose of this study is to investigate the outcome of patients with pathologies of the ascending thoracic aorta (diseases in the great blood vessel or artery that leads away from the heart) including type A aortic dissection, retrograde type A aortic dissection, intramural hematoma, penetrating ulcer or pseudoaneurysm who are suitable for endovascular (within the vessel) repair with the Medtronic Valiant PS-IDE (Physician Sponsored-Investigational Device Exemption) Stent Graft. Type A aortic dissection is a condition where blood passes through the inner lining or between the layers of the blood vessel from a tear in the aortic wall (dissection) in the ascending aorta; a retrograde Type A aortic dissection is a condition where the dissection or tear in the ascending aorta starts from the descending aorta; an intramural hematoma is a collection of clotted blood within the aortic wall; a penetrating ulcer has a plaque or clot within the wall and a pseudoaneurysm is a false aneurysm . If left untreated in any of these conditions, the aorta can enlarge and rupture causing injury or death. The plan for these patients is to repair the ascending thoracic aorta using the Medtronic Valiant PS-IDE Stent Graft with the Captivia Delivery System. The Valiant Captivia has been evaluated worldwide and used extensively in patients with type B (descending) thoracic aortic dissection. Since the dissections in the ascending aortas mirror that of the descending aorta, it is expected that this stent graft will deliver similar performance and endurance in patients with type A aortic dissection. The investigators expect to reroute the blood to the true lumen (the inner space within the blood vessel) by covering the proximal (nearest to the heart) tear with the stent graft. The stent graft is a stent frame made from Nitinol wire and covered with an expandable material made of a polyester material. This new study will determine how well the device works to treat dissections, intramural hematomas, penetrating ulcers and pseudoaneurysms in the ascending thoracic aorta.

Safety and Efficacy Of Amber Peripheral Liquid Embolic System

A prospective, single-arm, multicenter, open-label, First-in-Human \& Pivotal Study to assess the safety and efficacy of amber SEL-P in 70 patients requiring peripheral embolization: vascular anomalies, hemorrhages, aneurysms, and pseudoaneurysms, varicose veins, portal vein, hypervascular tumors, type -II endoleaks, and pathological organs. The study will be divided into two consecutive stages. Stage I will be dedicated to testing the device's safety, followed immediately by stage II, aimed to test the device's efficacy. The overall study sample will be used to assess the device safety and efficacy in all the enrolled participants.
