Embodiment Construction

[0033] The disclosed invention relates to expandable devices of the nature of perfused balloons. The novel features of the invention are set forth with particularity in the following claims. A better understanding of the features and advantages of the invention will be obtained by reference to the following detailed description and accompanying drawings, which illustrate illustrative embodiments in which the principles of the invention are utilized.

[0034] figure 1 Shown is an inflatable device 10 comprising a perfused balloon 12 in an inflated state ready for use in conjunction with surgery (but the balloon is intended for delivery through the vasculature to a selected treatment area, such as the aortic valve , will usually be collapsed). As can be appreciated by viewing the inflated state, the balloon 12 of the device 10 may have a plurality of expandable cells 12a (eight shown, but any number may be provided) in at least a single cross-section of the balloon (see, e.g.,...

Abstract

An apparatus 10 for delivering fluid flow in a blood vessel for performing a medical procedure, in particular aortic valvuloplasty. The device comprises: a shaft 16; an inflatable perfusion balloon 12 supported by the shaft and comprising an internal passage P for allowing fluid to flow in the blood vessel when the perfusion balloon is in an inflated state, and an internal passage P for controlling the flow of fluid within the passage. valve 18. The valve may be connected to the shaft or may comprise an elongated tube partially connected to the balloon. The balloon may comprise a plurality of cells in a single cross-section, each cell comprising a neck and a valve may be positioned in the space between the shaft and the neck for controlling the flow of fluid within the channel. Connectors are also available to control the position of the valve.

Description

[0001] Incorporate by reference [0002] All publications and patent applications mentioned in this specification are herein incorporated by reference to the same extent as if each individual publication or patent application was specifically and individually indicated to be incorporated by reference. Background technique [0003] Expandable devices, such as balloons, are widely used in medical procedures. In the case of a balloon, the balloon is typically located at the end of the catheter and inserted into the body until the balloon reaches the target area. Adding pressure to the balloon causes the balloon to inflate. In one variation of usage, the balloon creates a space within the body when inflated. [0004] Balloons can be used in valves associated with the heart, including during balloon aortic valvuloplasty (BAV) (as described in Hara et al., "Percutaneous balloon aortic valvuloplasty revisited: time for arenaissance?" Circulation 2007;115:e334-8 described above) an...
