    摘要: Trans-esophageal cardiac compression is performed during cardiopulmonary resuscitation by introducing into the esophagus a tube (12) having a distal inflatable member, such as a balloon (20). The balloon (20) is positioned in the esophagus (48) at the level of the ventricles of the heart (50). A rapidly cycling pump (16) (such as a compressible bag) is attached to the tube (12), and used to inflate and deflate the balloon (20) on the tube (12). As the balloon (20) inflates, it compresses the ventricles against the sternum (54), increases the transmural pressure across the ventricular wall, and propels blood out of the heart (50) into the aorta and pulmonary arteries. The balloon (20) is inflated and deflated at a rate of approximately 60 cycles to 80 cycles per minute to maintain perfusion of the heart, brain and other vital organs until more definitive therapy can reestablish the contractile activity of the heart. The balloon (20) can be inflated and deflated by a handheld pump (16), or by a rapidly cycling gas pump (100). A particular embodiment of the pump includes a larger volume pump that is driven by a smaller volume drive pump which cycles rapidly to force gas into and out of the balloon.

    摘要: A delivery catheter, with or without an inflation balloon, and coated with a heat activated adhesive to secure a stent thereon is disclosed. The adhesive has a phase transformation temperature just above the temperature of human blood, so that below the transformation temperature the adhesive is tacky, and above the transformation temperature the adhesive is non-tacky. In a stenting procedure, when the stent is mounted to the balloon catheter and the catheter is introduced into a body lumen, the adhesive is below the transformation temperature and remains tacky to hold the stent to the catheter. Once the stent-catheter assembly is positioned at the deployment site, a warm saline or dye solution is injected to heat the adhesive to above the transformation temperature. The adhesive becomes non-tacky and releases the bond between the catheter and deployed stent allowing the former to be withdrawn.

    摘要: An intragastric balloon device includes a flexible bladder, a relatively rigid reservoir coupled to the bladder and adapted to hold a bladder inflation fluid, and an inflation/deflation system adapted to move or permit movement of the fluid from the reservoir and into the bladder. The intragastric balloon device is sized such that it may be positioned, in its entirety, into the stomach cavity. Various systems may be used to move or permit movement of the fluid. A control system is provided to automatically activate the inflation/deflation system. The automatic activation may be activated by a combination of one or more of a timer, the temperature of the stomach, the pressure in the stomach, the mechanical stress in the stomach, or another sensed condition, at which the control system is programmed or otherwise configured to activate.

    摘要: A process and apparatus for occluding a vascular site. A catheter having a highly distensible occlusion balloon detachably mounted at a distal end thereof is provided to the vascular site and at least partially filled with an aqueous balloon inflation fluid which allows the balloon placement to be imaged. The balloon is porous to the aqueous inflation fluid and the inflation fluid is gradually displaced through the balloon pores by a liquid filling composition which is solidifiable on contact with the aqueous inflation fluid to produce a mass to which the balloon is nonporous. The filing composition is injected to bring the balloon wall into contact with the vessel wall at the vascular site. The balloon is detached from the catheter after the filling composition has at least substantially solidified and the catheter removed from the body.

    摘要: A balloon catheter for medical treatment of a patient has a proximal hub, flexible catheter shaft, a balloon, and an improved tip design. The catheter defines a guidewire lumen defined by a tubular inner body extending from a distal guidewire port to a proximal port located at a position proximal from the balloon. The guidewire lumen preferably has a constant cross-sectional area from the distal guidewire port to the proximal end of the balloon. At least one marker band is affixed to the inner body at a location within the balloon. A distal leg of the balloon is affixed to the inner body and a location between the marker band and the distal end of the inner body. A portion of the inner body extending in the proximal direction from the marker band has a substantially constant inner lumen diameter. However, the inner body wall thickness tapers to a narrower tip wall thickness, extending from a location between the marker band and the balloon distal leg, to the distal end of the inner body. A distal portion of the distal leg is also preferably tapered.

    摘要: An apparatus for exchanging over-the-wire balloon catheters engages a guide wire within a guide catheter. In one embodiment the engagement is by an inflatable balloon in the guide catheter. Alternatively, the engagement is accomplished by a captivation wire in the guide catheter that has a collapsible loop portion through which the guide wire extends. Inflation of the balloon or closing the loop portion of the captivation wire within the guide catheter traps the guide wire and restricts its movement relative to the guide catheter. Once the guide wire position is fixed, withdrawal of a first balloon catheter and subsequent introduction of a second balloon catheter over the guide wire is possible without moving the guide wire longitudinally. Thus, the positioning of the guide wire over a stenosis to be dilated is not disturbed.

    摘要: Methods and devices for separating plaque from vessel walls using everting membranes. Everting tubes disposed on catheters are used in one embodiment of the invention to separate plaque from blood vessel walls. One embodiment of the invention utilizes a single everting membrane including a fixed portion, a leading edge, and an advancing portion. The everting tube can have an interior which can be pressurized to propel the everting tube distal edge distally onward, so as to separate the plaque from the vessel inner wall. One device has double everting membranes fixedly attached to a tubular member and having facing advancing membrane portions which may be proximally fixed relative to one another, but are preferably both free to travel distally. The outermost tube can be laid down over the vessel inner wall and the innermost tube laid down over the plaque, with the advancing surfaces of each everting membrane facing each other. Fluid can be supplied under pressure to fill the interior of the everting tubes and thereby distally advance the tube leading edges. The present invention may be used in conjunction with distal emboli capturing filter or distal occlusion devices.

    摘要: A surgical balloon which is provided with a plurality of balloons so that a fixing property and a shielding property are simultaneously satisfied, and prevents a liquid or a gas from flowing from one area in the body to another area thereof. The surgical balloon is further provided with a balloon fixing device, a drain for draining water from the front nostril and a tube for supplying rinsing water into the nasal cavity so that a surgical operation using an endoscope is carried out inside the nasal cavity with the nasal cavity filled with a water flow. A high-pressure balloon having a fixing property and a low-pressure balloon having a shielding property are combined, and the balloon is pulled from the periphery of the front nostril so as to be secured; thus, a large amount of water supply and water drain are carried out through the front nostril. Therefore, it is possible to carry out a nose surgical operation using an endoscope in a water flowing, a strong rinsing operation after the surgical operation and a diagnosis inside the nasal cavity using a ultrasonic wave.
