摘要： Devices and methods are provided for temporarily inducing cardioplegic arrest in the heart of a patient and for establishing cardiopulmonary bypass in order to facilitate surgical procedures on the heart and its related blood vessels. Specifically, a catheter based system is provided for isolating the heart and coronary blood vessels of a patient from the remainder of the arterial system and for infusing a cardioplegic agent into the patient's coronary arteries to induce cardioplegic arrest in the heart. The system includes an endoaortic partitioning catheter having an expandable balloon at its distal end which is expanded within the ascending aorta to occlude the aortic lumen between the coronary ostia and the brachiocephalic artery. Means for centering the catheter tip within the ascending aorta include specially curved shaft configurations, eccentric or shaped occlusion balloons and a steerable catheter tip, which may be used separately or in combination. The shaft of the catheter may have a coaxial or multilumen construction. The catheter may further include piezoelectric pressure transducers at the distal tip of the catheter and within the occlusion balloon. Means to facilitate nonfluoroscopic placement of the catheter include fiberoptic transillumination of the aorta and a secondary balloon at the distal tip of the catheter for atraumatically contacting the aortic valve. The system further includes a dual purpose arterial bypass cannula and introducer sheath for introducing the catheter into a peripheral artery of the patient.

摘要： A drug or agent coated balloon having a length which is adjustable in vivo is described herein. The balloon is configured to be coated or coatable with one or more drugs where the coating may be applied prior to advancement into a patient body or prior to balloon expansion within the patient body. The length of the expandable portion of the balloon is adjustable to approximate a length of the tissue region to be treated. Moreover, the drug-coated balloon may be used alone or it may be utilized to deploy luminal prostheses having one or more linked or otherwise coupled segments.

摘要： Delivery catheters and systems are adapted for delivering multiple discreet prostheses in body lumens. An exemplary delivery catheter comprises a sheath, a pusher for moving the prostheses relative to the sheath, and a valve member for selectively retaining the prostheses in the sheath. For balloon expandable stents, an elongated shaft and an expandable member are slidably disposed in the sheath, and the prostheses are positionable on the expandable member for deployment in the body lumen. The valve member allows a selected number of prostheses to be deployed from the sheath while retaining other prostheses within the sheath.

摘要： An atherectomy catheter is provided for excising and imaging material in a body lumen. In one embodiment, the catheter comprises a catheter body, a cutting blade, and an imaging device. The cutting blade is mounted on the catheter body and configured to move between a first position and a second position relative to an aperture or cutting window. When the cutting blade is in the second position, the blade substantially closes the aperture on the catheter body. The imaging device which is mounted on or otherwise coupled to the cutting blade is configured to be in an imaging position when the cutting blade substantially closes the aperture or cutter window. This allows the imaging device to survey material within the cutting zone of the atherectomy catheter. By allowing the imaging device to view materials within this cutting zone, material may be imaged and then removed from the body lumen without having to reposition the catheter between each step.

摘要： A method is disclosed for mixed enclave operation of a computer network with users employing a multi-level network security interface and users without any network security interface. Either the network security user selects or the network security interface automatically selects whether communications are permissible with other unsecured users. Where a mixed enclave operation is selected, the network security user identifies when communications are being undertaken with another secured user or a non-secured user. Communications with a non-secured user at a lower security level entail securing the data residing with the secured user from transmission back to the non-secured user.

摘要： Prosthesis delivery devices and methods are provided that enable precise control of prosthesis position during deployment. The prosthesis delivery devices may carry multiple prostheses and include deployment mechanisms for delivery of a selectable number of prostheses. Control mechanisms are provided in the prosthesis delivery devices that control either or both of the axial and rotational positions of the prostheses during deployment. This enables the deployment of multiple prostheses at a target site with precision and predictability, eliminating excessive spacing or overlap between prostheses. In particular embodiments, the prostheses of the invention are deployed in stenotic lesions in coronary or peripheral arteries, or in other vascular locations.

摘要： Blood vessels and other body lumens are stented using stent structures comprising a plurality of radially expansible rings where at least some of the rings comprise axially extending elements which interleave with axially extending elements on adjacent unconnected rings. The ring structures may be open cell structures or closed cell structures, and the axially extending elements will typically be formed as part of the open cell or closed cell structure.

摘要： Catheters, kits, and methods are provided for removing material from a body lumen. The catheters and methods may be used in a variety of body lumens, including but not limited to coronary and other arteries. In general, the catheter has a cutting element that cuts material while the material is engaged by a material capture device on the catheter body. Preferably, the material capture device tensions the material during cutting, which reduces the amount of cutting force required. The material capture device typically follows a path that draws material into the catheter body. Preferably, but not necessarily, the material capture device may be arranged on the catheter body to advance along a path outwardly from the catheter body into the material and then inwardly towards the catheter body to tension the material. The cutting element on the catheter body moves between a first position and a second position to cut the material while in tension.
