    摘要: Disclosed is an apparatus and method for the treatment of the symptoms of obstructive prostatism. The apparatus comprises an expandable dilatation catheter and an axially elongate sheath, adapted for transurethral insertion via the external opening of the urethra. The sheath is ellipsoid in cross-section, and provides an initial path through which the catheter and a standard cystoscope lens is guided. Disposed near the proximal end of the expandable dilation portion of the catheter is a plurality of irrigation ports. A saline solution travels through an irrigation conduit and is secreted through the irrigation ports so as to flush away blood, etc., away from the lens of a cystoscope and provides the urologist with an unobstructed view of the dilation catheter and external urethral sphincter muscle. Once the catheter has been properly positioned with respect to both the bladder neck and the sphincter, the dilation balloon may be inflated to force open the affected prostatic urethra and eliminate the obstruction.

    摘要: A device for protecting cerebral vessels or brain tissue during treatment of a carotid vessel includes a catheter having a distal portion, a proximal portion and a lumen extending therebetween, the catheter including first and second expandable areas provided over the length of the catheter. The device includes a first elongate member insertable longitudinally through the lumen of the catheter, the first elongate member being configured for stretching at least a portion of the catheter and causing one of the first and second expandable areas to transition from an expanded state to a collapsed state. The device further includes a second elongate member insertable longitudinally through the lumen of the catheter, the second elongate member being configured for stretching at least a portion of the catheter and causing the other of the first and second expandable areas to transition from an expanded state to a collapsed state.

    摘要: A device and method for achieving hemostasis and leakage control in vascular structures and other body ducts or vessels in an emergency room or trauma situation. The device has at least one shunt that contains an obturator on an end of the shunt. The shunt is inserted into a damaged vessel or lumen for sealing the leak or hemorrhage. Two shunts that both contain obturators on one of their ends can be inserted into two different vessels or lumens when the vessel or lumen has been severed. The obturators allow for the improved ease of insertion into the vessel or lumen. The two shunts are then releasably attached to restore fluid communication through the vessel or lumen. The shunt is placed temporarily within the patient and then removed when definitive repair can be achieved by a qualified physician.

    摘要: A system for preventing air from entering a first catheter of a multi-catheter system. Air is prevented from entering the proximal end of the first catheter by an axially elongate chamber having an impeller, the chamber being affixed to the proximal end of the first catheter. The air is removed through a port near the centerline of the chamber. Liquid removed with the air is returned to the chamber to minimize liquid loss during the procedure. A second catheter inserted through the chamber and into the first catheter is unable to entrain gas into the first catheter because any gas that enters the chamber is routed to the centerline of the chamber where it is removed. Inflow of fluid from an external pump scrubs the second catheter shaft of air bubbles attached by surface tension.

    摘要: An adjustable annuloplasty device is described. The device includes a body member comprising a shape memory material, the body member configured to be placed at or near a base of a valve of a heart. The device further includes a hysteretic material configured to undergo magnetic hysteresis in response to a first activation energy, the hysteretic material being in thermal communication with the shape memory material. The body member may have a first size of a body member dimension in a first configuration and a second size of the body member dimension in a second configuration. When the body member is in position in the heart, a change from the first configuration to the second configuration changes a size of a dimension of the annulus of the valve.

    摘要: Systems and methods for delivering implantable devices, catheters, or substances in or near and/or restoring flow through body lumens, such as blood vessel lumens are described. A catheter having a proximal portion of a first diameter and a distal portion of a second diameter (smaller than the first diameter) is advanced into a body lumen. The distal portion of the catheter is caused to expand to a diameter that is larger than the second diameter but no larger than the first diameter. A working device is then advanced out of the distal end of the catheter and used to remove obstructive matter, deliver an implantable device or substance and/or restore flow. The distal portion can be reduced in diameter prior to removal from the body. A stand alone, guide catheter is also disclosed possessing high resistance to kinking even with a very thin wall.
