Methods for using blood pumps to treat heart failure are disclosed. The pump is mounted on an interior of a stent, and the stent is releasably mounted on a distal end of a catheter. The distal end of the catheter is inserted into a peripheral artery and advanced to position at a region of interest within the descending aorta, the ascending aorta, or the left ventricle. The stent and the pump are released from the catheter, and the pump is activated to increase blood flow downstream of the pump. The pump can also be positioned in the vena cava or used to treat right-sided heart failure following the insertion of an LVAD, or to improve venous return in patients with varicose veins. Non-stent pumps are described for insertion between the pulmonary vein and aorta, and between the vena cava and pulmonary artery designed for use during cardiac surgery.

Vitamin K is effective in counteracting cardiovascular disorders such as the reduction in arterial elasticity normally associated with the aging process. A pharmaceutical composition or nutritional formulation comprising vitamin K can be used to combat age-related stiffening of the arteries, and the consequences thereof, namely pulmonary congestion, hypertension, left ventricular hypertrophy, congestive (right sided) heart failure, left sided or left ventricular failure, chronic cardiac failure, angina pectoris, myocardial infarction, Mönckeberg's sclerosis and stroke. In various embodiments, vitamin K can also be used to reduce or reverse calcification of a blood vessel in pre-existing cardiovascular disorders such as arteriosclerosis.

A bearingless and sealless rotary blood pump is disclosed which provides multidirectional flow intended to provide low-pressure, high-volume right-sided partial assist circulatory support in a univentricular Fontan circulation on a permanent basis. The pump includes a housing and an impeller suspended in the center of the housing. The housing incorporates flow optimization features between inlet and outlet ends, as well as with the impeller surface. Large fluid gaps maintained between impeller and housing eliminate any potential for blood flow obstruction. The impeller contains some motor components. It includes a central stator and surrounding rotor. The motor includes a brushless DC outrunner electrical motor design. An electromagnetic stator core is surrounded by a circumferential passive magnetic ring. The rotor is further levitated about the stator spindle by a plurality of axially and radially located passive magnetic and hydrodynamic journal bearings on both ends of the spindle. The rotor is bearingless and sealless. During impeller rotation, blood entering the space between the rotor and stator is induced to flow by centrifugal pumping action and the fluid film separates the stator hydrodynamic bearings from the rotor so that there is no direct mechanical contact between the rotor and stator.

Semi-rigid stylets configured with a particular curve shaped and handle design to accurately advance either left-sided or right-sided double lumen endotracheal tubes to be positioned in the appropriate place are described. The semi-rigid stylets have a distal bend to counter or compensate for the inherent curvature of double lumen tubes imparted by the memory of spooled tubing stocks.
