For Attain Select II + SureValve delivery catheter system, use of the delivery catheter system is contraindicated in patients with obstructed or inadequate vasculature.

Warnings

The delivery catheter system is for single use only and is not intended to be resterilized.

Use the delivery catheter system only with compatible transvenous devices. No test data is available to demonstrate compatibility of the catheters with any device that is not manufactured or distributed by Medtronic. Consequences of using the catheters with incompatible devices may include the inability to deliver the transvenous device or damage to the transvenous device during delivery.

Handle the catheters with care at all times. Do not kink, stretch, or severely bend the catheters. Do not use surgical instruments to grasp the catheter shaft.  Do not use excessive force when inserting a catheter into a vessel. Ensure that the catheters are thoroughly flushed with saline or heparinized saline and free of air before use to avoid air embolism to the patient. Do not allow the catheter to come into contact with liquids other than blood, saline, or contrast solution.

Use care when passing a catheter through vessels and tissue. To minimize risk of perforation and dissection, do not push, pull, or rotate the catheter against resistance. If resistance is met, discontinue movement, determine the reason for resistance, and take appropriate action before continuing. Damage to the catheter may prevent it from performing with accurate torque response and control.

Flush the catheters through the proximal end of the catheter. The catheters must be thoroughly flushed and free of air before use. Do not use a power injection syringe to inject contrast solution.

Keep external defibrillation equipment nearby for immediate use during insertion, placement, acute lead system testing, or whenever arrhythmias are possible or intentionally induced. Backup pacing should be readily available during implant. For information about potential adverse events or complications, refer to the product documentation packaged with the products chosen. Use of the catheters or transvenous devices may cause heart block.

Thrombogenicity evaluations were conducted using a heparinized model. If your patient cannot be adequately anticoagulated, it is unknown whether thrombus formation may occur with this product.

For Attain Command + SureValve left-heart delivery system, due to the relative stiffness of the catheter, damage to the walls of the vessels may include perforations or dissections. When in the right chamber of the heart, the guide-catheter dilator must be retracted within the outer guide catheter tip to minimize the risk of perforation.

Potential complications

Potential adverse events related to the use of the delivery catheter system include, but are not limited to, the following:  air embolism, allergic reaction to contrast media, arteriovenous fistula formation, bleeding at the insertion site, brachial plexus injury, cardiac tamponade, dislodgement, dissection, endocarditis, heart block, hematoma formation, hemothorax, infection, irregular heart beat, mediastinal widening, perforation, pneumothorax, subclavian artery puncture, thrombophlebitis, thrombosis, valve damage, vascular occlusion, vessel damage.

Attain™ Deflectable Catheter Delivery System

Indications

The deflectable catheter delivery system is indicated to provide a pathway through which diagnostic and therapeutic transvenous devices are introduced within the chambers and coronary vasculature of the heart, and for introducing balloon catheters into the coronary sinus or leads into vessels of the left heart via the coronary sinus.

Contraindications

Use of the deflectable catheter delivery system is contraindicated for right ventricular use in patients with tricuspid valvular disease or a mechanical tricuspid heart valve. Use of the deflectable catheter delivery system is contraindicated in patients with obstructed or inadequate vasculature.

Warnings and Precautions

The deflectable catheter delivery system is for single use only and is not intended to be resterilized.

Use the deflectable catheter only with compatible transvenous devices. No test data is available to demonstrate compatibility of the deflectable catheter with any device not manufactured by Medtronic. No test data is available to demonstrate compatibility of transvenous devices larger than 2.1 mm (6.2 French), with the exception of the 2.3 mm (7.0 French) deflectable catheter dilator included in this package. Consequences of using the deflectable catheter with incompatible devices may include the inability to deliver the transvenous device or damage to the transvenous device during delivery.

Handle the deflectable catheter with care at all times. Do not kink, stretch, or severely bend the deflectable catheter. Do not use surgical instruments to grasp the deflectable catheter. Do not use excessive force when inserting a deflectable catheter into a vessel. Do not wipe the deflectable catheter with chlorofluorocarbon-based solvents. Ensure the deflectable catheter is thoroughly flushed with saline and free of air prior to use to avoid air embolism to the patient. Avoid contact with liquids other than isopropyl alcohol, blood, saline, or contrast solution.

Use care when passing the deflectable catheter through vessels and tissue.  Avoid damaging vessels and cardiac tissue, such as perforations and dissections, during deflectable catheter passage and positioning. Remove the dilator after the deflectable catheter assembly has been advanced into the right atrium to minimize the risk of perforation. Straighten the distal section as much as possible before removing the deflectable catheter from the patient to avoid vessel damage during removal.

Keep the cutting surface of the slitter in line with the hub and catheter shaft axis. Do not move the catheter or slitter in a back and forth motion. This ensures that the hub and guide catheter wall are cleanly slit by the slitter blade, preventing transvenous device damage and/or dislodgements.

Use the introducer valve to impede the backflow of venous blood during the implant procedure. Ensure that the side-port stopcock is closed before attaching the valve to the deflectable catheter hub. The side-port is for flushing the deflectable catheter only. Do not infuse through the side-port. When using the side-port, consider sealing the proximal opening of the introducer valve with a thumb or forefinger.

Use the side-port on the introducer valve to flush the deflectable catheter. The deflectable catheter must be thoroughly flushed and free of air prior to use. Do not use a power injection syringe to inject contrast solution.

Keep external defibrillation equipment nearby for immediate use during insertion, placement, acute lead system testing, or whenever arrhythmias are possible or intentionally induced. Backup pacing should be readily available during implant. Use of the deflectable catheter delivery system and/or transvenous devices may cause heart block.

Potential complications
