Implantable heart assist system and method of applying same
First Claim
1. An intravascular extracardiac pumping system for increasing perfusion of tissue of a patient through a renal artery, the system comprising:
- a pump configured to pump blood through the patient at subcardiac volumetric rates, said pump having an average flow rate that, during normal operation thereof, is substantially below that of the patient'"'"'s heart when healthy, the pump configured to be positioned within the vasculature of a patient; and
a pump housing having;
an inflow portion defining an axis, the inflow portion fluidly coupled to the pump to direct blood to the pump, the inflow portion configured to be positioned within the vasculature of the patient; and
an outflow portion extending generally laterally from the axis of the inflow portion, the outflow portion fluidly coupled to the pump to direct blood away from the pump, the outflow portion configured to be at least partially positioned within the renal artery of the patient;
whereby the pump and the inflow and outflow portions are configured so as to be inserted subcutaneously into the vasculature in a minimally-invasive procedure.

Abstract
An intravascular extracardiac pumping system for increasing perfusion through a renal artery to tissues of a patient without any component thereof being connected to the patient'"'"'s heart is provided. The system includes means for pumping blood and a portion that houses the pumping means. The portion that houses the pumping means is configured to direct blood from a location upstream of the pumping means to a location within a renal artery. The pumping means and the portion that houses the pumping means are configured to be insertable into a non-primary vessel subcutaneously in an minimally-invasive procedure for positioning within the patient'"'"'s vasculature.

44. An intravascular extracardiac pumping system for increasing perfusion through a renal artery to tissues of a patient without any component thereof being connected to the patient'"'"'s heart, the system comprising:
-
a means for pumping blood; and
a portion that houses the pumping means and is configured to direct blood from a location upstream of the pumping means to a first location within a first artery and a second location within a renal artery;
whereby the pumping means and the portion that houses the pumping means are configured to be insertable into a non-primary vessel subcutaneously in an minimally-invasive procedure for positioning within the patient'"'"'s vasculature. - View Dependent Claims (45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60)

61. A method for treating a patient without connecting any component to the patient'"'"'s heart, the method comprising the steps of:
-
inserting an inlet end of an inflow portion of an intravascular pumping system into the vasculature of a patient using a minimally invasive surgical procedure, the intravascular pumping system comprising a pump coupled with the inflow portion and an outflow portion coupled with the pump;
advancing the intravascular pumping system within the vasculature until the inlet end of the inflow portion is positioned at a first location within an artery and an outlet end of the outflow portion is positioned within a renal artery; and
operating said pump to pump blood through the renal artery to perfuse tissue at volumetric rates that are on average subcardiac. - View Dependent Claims (62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78)
