    摘要: A balloon catheter including an inflatable balloon affixed to a catheter. The proximal end of the balloon is affixed to the outer wall of the catheter so as to provide an air tight seal there between. A slip joint is formed between the distal end of the catheter and the distal end of the balloon to permit the distal end of the balloon to axially move or translate with respect to the distal end of the catheter. The slip joint allows the axial length of balloon to change during inflation or deflation without transferring tensile or compressive forces between the balloon and the catheter, thereby preventing transverse creases from forming in the surface of the balloon and preventing the catheter from bowing. Alternatively, the catheter may be terminated so as to not contact the distal end of the balloon, or the catheter can be segmented so that separate catheter parts are connected to each end of the balloon, thereby eliminating the slip joint altogether.

    摘要: A catheter balloon formed of a polymeric material such as expanded polytetrafluoroethylene (ePTFE) bonded to a second layer formed of a low tensile set polymer and/or impregnated with a low tensile set polymer. In a presently preferred embodiment, the low tensile set polymer is an elastomer selected from the group consisting of a silicone-polyurethane copolymer and a diene polymer. The low tensile set polymer has high strength, low modulus, high elongation, and low tensile set, to provide improved balloon performance. The diene or silicone-polyurethane has a low tensile set, which facilitates deflation of the balloon to a low profile deflated configuration. One aspect of the invention provides improved attachment of the diene to the ePTFE. In one embodiment, the second layer is formed of a diene mixed with a bonding promoter such as a vulcanizing agent which is covalently bonded to the diene.

    摘要: A mitral valve therapy device and method treats dilated cardiomyopathy. The device is configured to be placed in the coronary sinus of a heart adjacent to the mitral valve annulus. The device includes a force distributor that distributes an applied force along a pericardial wall of the coronary sinus, and a force applier that applies the applied force to one or more discrete portions of a wall of the coronary sinus adjacent to the mitral valve annulus to reshape the mitral valve annulus in a localized manner.

    摘要: The invention is based on the intention of creating a stomach probe with which a watertight closure of the oesophagus is possible. The stomach probe, according to the invention, is characterized by a tampon-bladder for watertight closure of the oesophagus, in which the tampon-bladder forms from flexible and/or elastic material at least a closed inner cavity for the reception of a fluid medium, through a means (11) of establishing a prescribed pressure for the medium in the tampon-bladder (16) by an inner lumen forming the actual stomach probe, from which an outer hose-like lumen (18) extending to the tampon-bladder (16) is so arranged that between the outer lumen (18) and the inner lumen (17) a channel is formed connected to the inner cavity of the tampon-bladder (16) arranged on the outer lumen (18) by a number of openings (20), whereby the inner cavity of the tampon-bladder (16) is connected via the canal formed between the inner and outer lumina (17, 18) with the means of production of pressure in the tampon-bladder, that is, with a suitably graded reservoir or equalizing vessel (11) for the liquid medium situated above the tampon-bladder and outside the patient.

One embodiment includes a catheter for insertion into a vessel-like structure, the catheter having a catheter wall and a movable member, a trap operably connected to the catheter wall and to the movable member, wherein relative motion between the catheter wall and the movable member actuates the trap. In one embodiment, the expanded trap is formed from struts in a spiral-shaped configuration. In one embodiment, the contracted trap forms a waist to creates a pinch-point to trap particles. In one embodiment, the contracted trap forms a cocoon-like structure to further trap particles. In one embodiment, the angioplasty device includes a handle to actuate the trap from a contracted position to an expanded position and return to a contracted position. The handle provides rotational or longitudinal or both types of movement to actuate the trap.

    摘要: A balloon dilatation catheter used for percutaneous transluminal coronary angioplasty includes a coaxial construction of an inner tube and an outer tube. The inner tube extends distally beyond the distal end of the outer tube. A dilatation balloon is mounted on the distal end of the catheter and is connected at its proximal end to the distal end of the outer tube and at its distal end to the distal end of the inner tube. The lumen of the inner tube is adapted to receive a guidewire and may permit pressure monitoring and liquid infusion. The annular inflation lumen is defined between the inner and outer tubes. The distal end of the outer tube extends into the balloon and is anchored directly to the inner tube. The balloon may be inflated and deflated through an annular inflation lumen defined between the inner and outer tubes, there being openings in the outer tube within the balloon to communicate the inflation lumen with the interior of the balloon. The catheter displays increased column strength and resistance to axial buckling and balloon bunching by reason of the secure connection between the distal end of the outer tube and the inner tube.
