摘要： A recanalization catheter for facilitating re-entry into a lumen of a blood vessel from a subintimal space. The catheter includes an inflatable balloon mounted on a distal end region of the catheter shaft of the catheter. The catheter shaft includes a guidewire lumen having a distal opening and a lateral opening in a distal region of the catheter shaft proximal of the distal opening, and an inflation lumen in fluid communication with the balloon. The balloon is configured to be inflated in the subintimal space to a first inflation state at inflation pressures below a threshold inflation pressure to orient the lateral opening toward the lumen of the blood vessel, and inflated to a second inflation state at inflation pressures above the threshold inflation pressure. The catheter includes means for retaining the balloon in the first inflation state at pressures below the threshold inflation pressure.

摘要： An embolic filter balloon is disclosed. The embolic filter balloon may comprise an inflatable balloon portion. Further, the inflatable balloon portion may be coupled to a filter member. The embolic filter balloon may be disposed in a body lumen. In some embodiments, the embolic filter balloon may be configured such that when the inflatable balloon portion is at least partially inflated the filter member extends at least partially across the body lumen. Such a configuration may allow the embolic filter balloon, when deployed, to filter particles greater than a predetermined size from a fluid in the body lumen.

摘要： Catheter including an inner tubular member having a fluid lumen defined therein and an exterior surface. The exterior surface defining a first distal flow port and a second distal flow port. An outer tubular member is movable relative to the inner tubular member in a proximal direction and having an interior surface. A first pressure chamber is defined between the exterior surface and the interior surface, and between a first distal seal assembly and a first proximal seal assembly. A second pressure chamber is defined between the exterior surface and the interior surface, and between a second distal seal assembly and a second proximal seal assembly.

摘要： The present invention relates to apparatus for retroperfusion of tissues and organs. The apparatus comprises a catheter with a proximal end for engaging a supply of the fluid medium, and a distal end having an expandable-contractible chamber for installation into suitable vessels or organs. The expandable-contractible chamber comprises a conduit element having a fluid- filled hollow wall defining a lumen. The conduit element has a first deformable inner-facing section approximate a proximal end of the conduit and a second deformable inner-facing section approximate a distal end of the conduit element. Controlled application of a pressure at a proximal end of the conduit element causes deformation of the conduit into the lumen at its distal end thereby occluding the flow of fluid medium through the catheter. Controlled release of the pressure releases deformation of the fluid-filled conduit at its distal end thereby unblocking the flow of the fluid medium through the catheter.
摘要翻译：本发明涉及组织器官的后灌注装置。该装置包括具有用于接合流体介质的供给的近端的导管，以及具有用于安装到合适的血管或器官中的可扩张收缩室的远端。可扩张收缩室包括具有限定内腔的流体填充中空壁的导管元件。导管元件具有近似于导管的近端的第一可变形内壁部分和近似于导管元件的远端的第二可变形内表面部分。在导管元件的近端受到控制的压力导致导管在其远端处进入内腔，从而阻塞通过导管的流体介质的流动。压力的控制释放释放了流体填充管道在其远端处的变形，从而解除流体介质通过导管的流动。

摘要： A valvuloplasty catheter has a dog-bone shaped balloon with semi-compliant smaller diameter waist and non-compliant larger diameter bulbous end regions. The balloon centers across the valve with the waist adjacent to the annulus. One bulbous region serves to hyperextend the valve leaflets and the other assists in stabilizing the balloon position to reduce migration. The semi-compliant waist increases in diameter as fluid enters the balloon until it comes into contact with the valve annulus. The pressure within the balloon per unit of volume delivery has a greater slope after contact with the annulus than before resulting in a change in slope for the pressure versus volume curve. The diameter of the balloon and annulus are determined at this inflection point when the balloon contacts the annulus.

摘要： A system (1) for dilating an occlusion (3) in an oesophagus (4) comprises a device (5) having a catheter (8) extending from a proximal end (9) to a distal end (10). An inflatable balloon (12) defining a hollow interior region (14) is located on the catheter (8) adjacent the distal end (10) thereof for dilating the occlusion (3). The balloon (12) is inflated with a saline solution by a pump (34) through an axial communicating bore (20) and radial communicating bores (21) in the catheter (8). A pair of stimulating electrodes (25) on the catheter (8) within the balloon (12) adjacent axially opposite ends (18,19) thereof receive stimulating voltage signals from a signal generator (43). Receiving electrodes (28) on the catheter (8) between the stimulating electrodes (25) produce resulting voltage signals in response to the stimulating current signal on the stimulating electrodes (25) which are indicative of the transverse cross-sectional area of the balloon (12) adjacent the receiving electrodes (28) when the balloon (12) is inflated with the saline solution. A microprocessor (35) determines the diameter of the balloon (12) at the receiving electrodes (28) from the resulting signals thereon, and displays a three-dimensional image (46) of the balloon (12) on a visual display screen (47) as well as the corresponding diameter values in windows (48) on the visual display screen (47). A surgeon observes an image of the balloon (12) which corresponds to an image of the occlusion (3) and adjacent portion of the oesophagus (4) during dilating of the occlusion (3).
