Benefits of technology

The solution effectively prevents restenosis and artery collapse by delivering materials to enhance wall structure, reducing the risk of thrombosis and improving treatment efficacy while maintaining balloon integrity and patient safety.

Problems solved by technology

One problem with this method is restenosis, in which the artery responds to the PTCA procedure by inflammation and inward growth.
Another problem is collapse of the wall of the artery back into its lumen.
Some problems have been reported with these methods, for example, thrombosis formation.

Embodiment Construction

Overview

[0086]FIG. 1 shows a flowchart of a method and FIGS. 2A-2E illustrate the acts of the method, of applying material(s) to and / or driving material(s) into the walls of a blood vessel, in accordance with an exemplary embodiment of the invention. FIGS. 2A-2E are discussed in parallel with the description of FIG. 1. Variations on the devices and / or methods are described following.

Exemplary Method

[0087]FIG. 1 is a flowchart 100 of a method of treating blood vessels, in accordance with an exemplary embodiment of the invention.

[0088] At 102, a narrowing or other problem in a wall 204 of a blood vessel 200 (FIG. 2A) is identified. Optionally, the narrowing is a plaque deposit 206, for example, a deposit with a calcified filling 202.

[0089] At 104, a catheter treatment system 210 (FIG. 2B) is inserted into the body and guided to the narrowing. Optionally, system 210 is used also to identify the problem, for example, including a contrast material port (not shown) or an imager (no...

Abstract

A balloon for injecting material into a wall of a hollow organ of a human, comprising: an expandable balloon body having a surface and having an axis; at least one predefined ejection port on said body adapted for ejection of fluid therefrom, in a transaxial direction; and an impulse source configured for and adapted to eject material out of said point at a velocity and shape suitable for mechanically penetrating tissue adjacent said port.

Description

RELATED APPLICATIONS [0001] The present application claims the benefit under 119(e) of 60 / 587,335 filed Jul. 14, 2004, 60 / 599,884 filed Aug. 10, 2004, 60 / 603,262 filed Aug. 23, 2004 and 60 / 675,477 filed Apr. 28, 2004, an inventor common to all of these applications is Mordechay Beyar, the disclosures of which are incorporated herein by reference.FIELD OF THE INVENTION [0002] The present invention relates to the delivery of materials, for example, high speed intrabody needle-less injection. BACKGROUND OF THE INVENTION [0003] A common treatment for a blocked artery, especially a coronary artery, is PTCA, in which a balloon is inflated inside the lumen of the artery, causing the lumen to increase, while compressing the blockage and / or forcefully expanding the artery. One problem with this method is restenosis, in which the artery responds to the PTCA procedure by inflammation and inward growth. Another problem is collapse of the wall of the artery back into its lumen. [0004] The use of...
