The sheath is provided in one size (14F), with a working length of 75 cm and a bi-directional distal tip to provide positioning in the cardiac anatomy. The handle is equipped with a deflection knob to deflect the tip clockwise 120° and counterclockwise 0°. The body of the sheath is radiopaque for visibility under fluoroscopy and has a marker band located in the distal tip. The dilator eases penetration of tissue. The sheath and dilator utilize a dual curve in two dimensions, resulting in a three-dimensional geometry. The 14F flush adapter facilitates the attachment of additional components.
V. INDICATIONS FOR USE
The Amulet™ Steerable Delivery Sheath is indicated to facilitate the delivery of the Amplatzer™ Amulet™ Left Atrial Appendage Occluder.
VI. COMPARISON OF TECHNOLOGICAL CHARACTERISTICS
The Amulet Steerable Delivery Sheath incorporates substantially equivalent design, function, packaging, sterilization process, materials, fundamental technology, indication for use, and operating principles as those shared by the predicate Amulet Steerable Delivery Sheath (K232690).
A comparison of the proposed Amulet Steerable Delivery Sheath and the predicate Amulet Steerable Delivery Sheath show these devices have substantially equivalent design characteristics, including a deflectable sheath, dilator, and adapter. The difference between the subject device and predicate is the in-process solvent used to prepare the surface of the distal tip PEBAX extrusions. Additionally, a tip bond tensile specification and in-process tensile test method are being implemented. The tip bond tensile specification aligns with currently defined product requirements.
