Abstract
Systems and methods of supplementing blood flow from the heart of a patient involving superficial, non-invasive procedures. In one general method, a first conduit is directed into the left side of the heart, a second conduit is directed into a superficial vessel and a pump is connected between the first and second conduits. The pump is implanted superficially in the patient and a power supply is connected to the pump. Blood is then suctioned from the left side of the patient's heart through the first conduit into the pump and expelled from the pump into the second conduit and the superficial vessel. A transcutaneous power supply is disclosed in one aspect and includes an external portion with a connection and alignment feature to assure reliable transmission of power.
Claims20
A method of supplementing the blood flow from the heart of a patient using a pump assist system, the method comprising:
- directing a first conduit into the left side of the heart,
- coupling a second conduit in fluid communication with a superficial artery of the patient,
- connecting a pump between the first and second conduits,
- implanting the pump in a superficial, subcutaneous area of the patient,
- connecting an electrical power supply to the pump,
- suctioning blood from the left side of the heart through the first conduit and into the pump, and
- expelling the blood from the pump into the second conduit and the superficial artery.
A system for supplementing blood flow from the heart of a patient, the system comprising:
- a first conduit configured to be directed transeptally into the left side of the heart,
- a second conduit configured to be coupled for fluid communication with a superficial artery of the patient,
- a third conduit,
- a fourth conduit,
- a pump configured to be superficially implanted within the patient and connected with the first and second conduits to suction blood from the first conduit and expel blood into the second conduit, and
- a second pump connected with the first pump and operatively coupled to the third and fourth conduits for suctioning blood from the third conduit and expelling the blood into the fourth conduit.
A system for supplementing blood flow from the heart of a patient, the system comprising:
- a first conduit configured to be directed into the left side of the heart,
- a second conduit configured to be coupled for fluid communication with an artery of the patient,
- a pump configured to be implanted within the patient and connected with the first and second conduits to suction blood from the first conduit and expel blood into the second conduit, and
- a return conduit coupled with an outlet of said pump and another portion of said system for returning a portion of blood expelled by said pump from the return conduit to said other portion of said system.
A method of supplementing the blood flow from the heart of a patient using a pump assist system, the method comprising:
- directing a first conduit into the left side of the heart,
- coupling a second conduit in fluid communication with a superficial artery of the patient,
- connecting a pump between the first and second conduits,
- implanting the pump in a superficial, subcutaneous chest region of the patient,
- suctioning blood from the left side of the heart through the first conduit and into the pump, and
- expelling the blood from the pump into the second conduit and the superficial artery.
