Intervention model description: The study is observational and intended to provide ongoing support for the approximately 20 remaining subjects enrolled in the DelIVery for PAH Study including support of pump refills and system replacements. The study is expected to continue at the eight (8) remaining centers located in the United States that have current DelIVery for PAH study subjects enrolled.
Primary purpose: SUPPORTIVE_CARE

Brief summary: The purpose of the DelIVery for PAH clinical study is to evaluate the safety of the Medtronic Model 10642 Implantable Intravascular Catheter when used with the Medtronic SynchroMed® II Implantable Infusion System to deliver Remodulin® (treprostinil) Injection.

As of June 2021, PMA approval of the Implantable System for Remodulin (ISR) is no longer being pursued and development and commercialization efforts have been halted. The approximately 30 subjects still implanted with the PIVoT system require a pathway for continued support. This protocol is amended and is designed to allow such ongoing support.

Detailed description: Pulmonary arterial hypertension (PAH) is a severe, chronic syndrome affecting the small pulmonary arteries (blood vessels which carry blood from the heart to the lungs to pick up oxygen). At the time of the initiation of this study, no cure exists for this disease. Medtronic has developed a fully implantable, long term, intravenous infusion system, which has the potential to enhance patient convenience and ease of use, while reducing the opportunities for catheter-related infections and complication issues associated with currently used external delivery systems. The information gained from this study could provide evidence to support use on an implantable infusion system for the management of other disease states requiring chronic intravenous therapy. Additionally, information collected from this study may contribute to the design of new product(s)/therapy(ies) and/or instructions for use.

The purpose of this clinical study is to evaluate the safety profile of the Model 10642 Implantable Intravascular Catheter portion of the PAH Implantable Vasodilator Therapy (PIVoT) system. This study will focus on the safety of delivery of Remodulin Injection in the treatment of patients with PAH who meet the approved Remodulin Injection indication, using the approved formulation, and approved intravenous route of administration.

The Model 10642 Implantable Intravascular Catheter being used in this study is investigational, meaning it has not been approved by the FDA to be safe. The Model 10642 Catheter is different from other commercially available drug delivery catheters because the Model 10642 Catheter tube has a one-way valve designed to allow the medication to flow out but keep blood from flowing back into the catheter tube. The Model 10642 Catheter is reinforced to prevent kinking and crushing, which could interrupt the flow of medication.

Remodulin Injection is a Food and Drug Administration (FDA) approved drug for the intravenous and subcutaneous treatment of PAH.

The SynchroMed II Implantable Infusion System is approved by the FDA to deliver specific drugs in patients who have chronic pain, need management of severe spasticity, and for cancer treatment but has not been approved to deliver Remodulin Injection in patients with PAH.

There is also a Catheter Imaging Sub-Study that is being done to measure the shape change of the Model 10642 Implantable Intravascular Catheter during a given set of patient positions through the use of x-ray imaging. This data will help us develop more clinically realistic bench tests and simulations that better mimic the challenges experienced by an implanted catheter. This Catheter Imaging Sub-Study will be conducted at up to seven centers and will enroll up to forty patients that are currently enrolled in the DelIVery for PAH clinical study and are at least three months post-implant of their current catheter and pump.
