6458070, Oct 1, 2002

Filed:

Dec 21, 1999

Appl. No.:

09/469103

Inventors:

Ron Waksman - Atlanta GA

Assignee:

Novoste Corporation - Norcross GA

International Classification:

A61N 500

US Classification:

600 3

Abstract:

Apparatus and method are described for delivery of a treating element, such as a radiation source, through a catheter to a desired site in the vascular system of a patient, such as a coronary artery, for inhibiting the formation of scar tissue such as may occur in restenosis following balloon angioplasty. The apparatus includes an elongated flexible catheter tube having proximal and distal end portions, with a lumen extending therebetween, and a diameter sufficiently small for insertion in to a patients vascular system. One or more treating elements, such as a capsule or pellet containing radioactive material, is positionable within the lumen and movable between the proximal and distal end portions under the force of liquid flowing through the lumen. A method for using such apparatus, including a method for using such apparatus simultaneously with a balloon angioplasty procedure, is disclosed.

Assignee:

International Classification:

A61M 2900

US Classification:

604108

Abstract:

A blood containment, visualization and tactile confirmation device is provided for use with a vascular entry needle. The device includes a visualization channel and/or a compliant outer wall portion which indicates whether a needle connected to the device has entered a selected blood vessel. The visualization channel is vented to the outside to allow displaced air to escape, but has a gas permeable member to prevent blood from escaping. The visualization channel may have one, two, or more stages, with a first stage chamber which indicates initial penetration of a selected blood vessel, and a second stage chamber which fills more slowly and indicates that the needle remains positioned within the blood vessel. A third stage chamber with entrapped air which compresses slightly due to the heartbeat may also be used. Preferably, a compliant outer wall portion pulses with changes in blood pressure, thereby providing a tactile indication that the needle tip is properly positioned.
