Problems solved by technology

However, when the balloon is inflated, the heart valve must temporarily fail
This can lead to disruption of blood flow, including poor backflow

Embodiment Construction

[0028] The disclosed invention relates to an inflatable device, essentially a perfused balloon. The novel features of the invention are set forth with particularity in the appended claims. The features and advantages of the present invention will be better understood by reference to the following detailed description, in which exemplary embodiments employing the principles of the invention are set forth, and accompanying drawings.

[0029] figure 1 Shown is an inflatable device 10 comprising a perfused balloon 12 in an inflated state, ready for use in connection with a medical procedure (although the balloon is normally collapsed for delivery through the vasculature to a selected treatment area, such as the aortic valve). Observing the inflated state, the balloon 12 of the device 10 may be in at least a single cross-section of the balloon (see e.g. Figure 2A and 3A ) has a plurality of inflatable cells 12a (eight shown, but any number can be provided). A retainer, such a...

Abstract

An apparatus for performing a medical procedure and, in particular, an aortic valvuloplasty, in a vessel for transmitting a flow of fluid includes a first inflatable balloon, such a perfusion balloonwith a plurality of cells in a single cross-section of the balloon for permitting the fluid flow in the vessel. An inflatable valve, which may take the form of a second inflatable balloon, may be provided for controlling the fluid, flow through the first balloon when inflated. Through selective movement of the second balloon when inflated via the flow rhythms created by the beating heart, a one way valve results that can be used to mimic the natural flow created by the valve under treatment.

Description

[0001] incorporated by reference [0002] All publications and patent applications mentioned in this specification are hereby incorporated by reference into this application as if each individual publication or patent application was specifically and individually indicated to be incorporated by reference. Background technique [0003] Inflatable devices, such as balloons, are widely used in medical procedures. In the case of a balloon, it is generally inserted over the end of the catheter until the balloon reaches the desired area. Pressurize the balloon to inflate the balloon. In a variation of usage, the balloon creates a space within the body when the balloon is inflated. [0004] Balloons can be used in valves associated with the heart, including during balloon aortic valvuloplasty (BAV) (as Hara et al. "Percutaneous balloon aortic valvuloplasty revisited: time for anaissance?" Circulation 2007;115:e334-8 described above) and during transcatheter aortic valve implantati...
