Hancock Specialty Products
Medtronic’s Hancock® Bioprosthetic Valved Conduits are designed for use in reconstructive procedures for the repair of congenital or acquired cardiac and great vessel malformations or pathology.
Summary
Hancock Bioprosthetic Valved Conduits
Hancock® Bioprosthetic Valved Conduits consist of a porcine aortic valve sutured into the center of a woven fabric conduit. The Hancock conduits are recommended for reconstruction of congenital or acquired cardiac and great vessel malformations or pathology.
These valved conduits are not intended for aortic root replacement.
Because the Hancock valved conduit does not incorporate a stent, the ratio of conduit outer diameter to inner diameter of the bioprosthesis is optimized.
The Hancock valved conduit is available in a wide range of sizes and models. Features include:
- Haynes alloy #25 annulus ring prevents annular and leaflet distortion and preserves orifice shape.
- A reinforcing ring external to the conduit prevents loss of leaflet coaptation and allows radiographic visualization.
Important Safety Information
Preclotting of the Hancock 105 and 150 valved conduits is recommended to minimize chance of hemorrhage. Reported complications include: valvular thrombosis, thromboembolism, calcification and fibrosis, valvular insufficiency, perivalvular insufficiency, valvular stenosis, leaflet perforation, significant transvalvular pressure gradients in small size bioprostheses, valve contamination, development of intraluminal peel, and hemorrhage through the graft and anastomotic sites.

Hancock Apical Left Ventricle Connectors
Hancock Apical Left Ventricle Connectors, which are used with Hancock low-porosity valved conduits (Model 105), provide an alternate method for relief of left ventricular outflow tract obstruction. The Hancock connector is curved at a 90° angle to facilitate anastomosis to the descending aorta. Low-porosity (50 mL/H2O/cm2/min at 120 mmHg) woven fabric extends through a flexible polypropylene stent for anastomosis to a Hancock 105 bioprosthetic valved conduit. An additional suture ring is provided to control the depth of penetration into the left ventricle. Each Hancock Apical Left Ventricle Connector is packaged sterile in double-aseptic transfer pouches.
NOTE: Intended for use in conjunction with Hancock low-porosity valved conduit, Model 105, and Hancock Trocar, Model H1701A.
Important Safety Information
The potential for interstitial blood loss exists, particularly in patients with hemodilution or clotting factor deficiencies. Minimize serious bleeding complications by preclotting the connector and/or valved conduit. Thromboembolism, while infrequent, has been reported. Do not use if severe coronary insufficiency, severe or symptomatic carotid occlusive disease, or thoracic aortic aneurysmal diseases are present.
