    摘要: A variable length balloon catheter is provided. The balloon catheter includes a catheter shaft having a distal portion, a balloon and an adjustment device. The balloon is in fluid communication with a distal end of the catheter shaft. The adjustment device includes an outer sleeve and an attachment structure. The outer sleeve is configured to be generally co-axially received over the distal portion of the catheter shaft and includes a distal end configured to restrict inflation proximal the distal end. Further, the outer sleeve is configured such that at least a portion of the outer sleeve is slidable relative to the distal portion of the catheter shaft such that a distal end of the outer sleeve relative to the balloon can be varied. The attachment structure is similarly disposed at the distal portion of the catheter shaft and is configured to selectively secure at least a portion of the outer sleeve to the distal portion of the catheter shaft such that the outer sleeve will not move upon inflation of the balloon.

    摘要: The invention provides devices that can be used to deliver a therapeutic agent to a treatment site within the vessel of a patient at increased pressure, while limiting the contact with and pressure placed on the vessel walls. Devices according to the invention include an expandable structure arranged around and on a tube having a lumen. The expandable structure may include a sealing ring that makes contact with the interior surface of a vessel to prevent or decrease fluid flow during delivery of a therapeutic agent. This allows delivery of a therapeutic agent with decreased risk of injury to the treatment site. The invention also provides for large lumen diameters, preventing shearing stress on therapeutic agents such as cell slurries.

    摘要: A catheter is disclosed which includes an over-the-wire type balloon catheter, with a guide wire, wherein the catheter incorporates an axially movable inner tubular member which extends proximally through a proximal manifold lumen. The inner tubular member extends distally beyond the distal end of the outer tubular member with the balloon member distal waist affixed to the inner tubular member proximate the distal end. The catheter incorporates axial tension members which function to transmit force to the distal tip when the movable inner tubular member is oscillated axially. The axial tension members are preferably a plurality of wires, each having a proximal end affixed to the outside diameter of the inner tubular member proximate the manifold, and each having a distal end affixed to the outside diameter of the inner tubular member a substantial distance distal of the manifold. When the inner tubular member is pulled proximally, energy is stored in the catheter, which when the inner is released, forces the distal tip forward with added force from the distal point of attachment of the axial tension members. An actuator and a valve assembly are preferably included.

    摘要: An improved deployment system deploys a stent to maintain the patency of a dilated vessel. The improved stent deployment system is adapted for deployment with a balloon catheter. The stent deployment system includes an expandable stent sheath for supporting the stent for deployment. The stent sheath is movably coupled to a catheter shaft and is relatively short in comparison to the catheter shaft. The stent sheath is movably coupled to the catheter shaft for movement between a retracted position and an advanced deployment position aligned with the balloon for expansion via the balloon for deployment of the stent supported thereby.

    摘要: An apparatus and method for catheter-based sensing and injection at a target site within a patient's body. An injection catheter is equipped with electrodes at its distal end which contact the surface of a target site, such as an AV node of the heart. Electrical signals detected at the target site by the electrodes are fed via leads to the proximal end of the catheter, where they are received by a monitor, such as an EKG monitor. If the electrical signals satisfy predetermined criteria, a needle within the catheter is extended into the target site, and a therapeutic agent is injected into the target site.
