1. An intraventricular apparatus, comprising:
- a substantially tubular sidewall that extends substantially axially between spaced apart first and second ends, an opening located proximal the first end;
a valve located adjacent the first end to provide for substantially unidirectional flow of blood therethrough; and
at least one aperture extending through the tubular sidewall at an axial location between the valve and the second end to provide for substantially free flow of blood between an interior and an exterior of the sidewall.

Abstract
An intraventricular apparatus includes an elongated body having a substantially tubular sidewall that extends substantially axially between spaced apart first and second ends, an opening located proximal the first end. A valve is located adjacent the first end to provide for substantially unidirectional flow of blood therethrough. At least one aperture extends through the tubular sidewall at an axial location between the valve and the second end to provide for substantially free flow of blood between an interior and an exterior of the sidewall.

16. An intraventricular apparatus comprising:
-
an elongated substantially cylindrical sidewall that extends substantially longitudinally between spaced apart first and second ends; an opening at the first end that permits flow of fluid relative to an interior lumen of the elongated body; a valve located between the opening and an axial length of the sidewall that extends between the valve and the second end, the valve permitting substantially unidirectional flow of fluid through the valve; and a plurality of apertures through an inflow section of the sidewall between the valve and the second end to permit substantially free flow of blood between an interior of the inflow section and a location external to the inflow section; and at least one support member to maintain a substantially cylindrical configuration of the sidewall near at least some of the plurality of apertures. - View Dependent Claims (17, 18, 19, 20, 21)

22. An intraventricular apparatus comprising:
-
elongated means for providing a lumen that extends within a substantially cylindrical sidewall between spaced apart first and second ends; means for providing an opening at the first end of the elongated means that permits flow of fluid through the opening relative to an interior of the elongated means; means for providing substantially unidirectional flow of fluid axially through a portion of the elongated means proximal the first end of the elongated means; means for permitting substantially free flow of the fluid through the sidewall of the elongated means; and means for maintaining a substantially cylindrical configuration of the sidewall of the elongated means between the second end and the means for providing unidirectional flow of fluid.
