  • Patent number: 8721515
    Abstract: An implantable aortic blood pump includes a rigid body having wall extending along a long axis and defining an inflation port portion with an inflation aperture therethrough. The aperture is fluid communication with an inner surface of the body and on a fluid supply, the body is preferably independent of an external brace or an external stiffener, yet still has a cantilevered deformation of less than 8 millimeters in response to a 200 gram weight suspended from a front body edge. A deflecting structure of a membrane deflects in response to fluid pressure so as to pump blood when the pump is secured to a subject aorta.

  • Patent number: 8104474
    Abstract: A collateral ventilation bypass trap system directly linked with a patient's lung or lungs may be utilized to increase the expiratory flow from the diseased lung or lungs, thereby treating one aspect of chronic obstructive pulmonary disease. The system includes a trap, a filter/one-way valve and an air carrying conduit. The system also includes a retention device for securing system elements in position.

  • Patent number: 7972293
    Abstract: A nasal plug for preventing excessive fluid discharge from a nasal passage includes a plug element fabricated from an absorbent material. The plug element has a size and configuration adapted and constructed to fit into a human nasal passage. A shaft portion extends from the plug element. The shaft portion is formed as an extension of the plug element and is fabricated from the same material as the plug element. A flexible sheathing is provided on the shaft portion.

  • Patent number: 7849861
    Abstract: An improved catheter device for selectively isolating and occluding a portion of the iliac vasculature of a patient includes an elongate hollow catheter shaft which is advanceable though the vascular system of the patient. The catheter shaft has a proximal portion that extends out from the patient and a distal portion adapted to be disposed within the iliac vasculature of the patient. A plurality of expandable members are disposed on the distal portion. One expandable member is dimensioned and configured so that when expanded it rests within the bifurcation of the descending aorta to the common iliac arteries (and/or within the bifurcation of the inferior vena cava that leads to the common iliac veins) so as to fixate the catheter within the iliac vasculature of the patient. At least two other expandable members are spaced apart from the fixation member and configured to selectively isolate and occlude blood flow through different portions of the iliac vasculature.

  • Patent number: 7806857
    Abstract: Methods and apparatus are provided for temporarily excluding an aneurysm or an arterio-venous fistula from a flow path by transluminally disposing a hollow balloon catheter structure within the aneurysm so that its proximal and distal ends extend past the aneurysm while maintaining continuity of the flow path, and then injecting a synthetic molding material or a biological hardening agent into the aneurysm cavity to cause solidification of the volume within the cavity. Once the material within the excluded aneurysm has solidified, the balloon catheter structure is deflated and removed, so that the hardened mass forms a new lining for the organ or vessel, and relieves the weakened tissue of the aneurysm or fistula from further flow-induced stress.

  • Patent number: 7264609
    Abstract: A self-retaining catheter that eliminates the problem of residual urine and also of bladder wall irritation caused by continuous contact with a spherical retention balloon which does not rely on a stylet for placement. The system may use an internal control wire that reversibly foreshortens the proximal end of the catheter thus radially displacing longitudinal strips defined in the proximal catheter to form retention wings. Alternatively, a balloon situated between the longitudinal strips is inflated to force open the retention wings once inside the urinary bladder. Radial displacement of the retention wings widens the spaces between the longitudinal strips, these spaces constituting the drainage apertures which permit complete emptying of the urinary bladder. The radially displaced retention wings abut the bladder wall in a non-continuous manner thereby reducing the area of bladder-catheter contact and further reducing bladder wall irritation.

  • Publication number: 20040260397
    Abstract: Systems for minimally invasive disc augmentation include an anulus augmentation component and a nucleus augmentation component. Both are suited for minimally invasive deployment. The nucleus augmentation component restores disc height and/or replaces missing nucleus pulposus. The anulus augmentation component shields weakened regions of the anulus fibrosis and/or resists escape of natural nucleus pulposus and/or the nucleus augmentation component. Methods and deployment devices are also disclosed. Methods of closing a defect in an anulus fibrosus of an intervertebral disc using a barrier are also provided.

  • Patent number: 6736793
    Abstract: A detachable balloon system includes an inflatable balloon with a self-sealing valve. The balloon has an elastomeric membrane and a proximal opening. The self-sealing valve is made up of a valve body for receiving an inflation instrument to inflate the balloon. The valve body is preferably formed of a biocompatible elastomeric material and includes a base portion and a sealing portion. The base portion is bonded to the elastomeric membrane so as to seal the proximal opening of the balloon. The sealing portion is located within the balloon and extends distally from the base into the balloon. The sealing portion is compressibly sealable in response to a pressure within the balloon following inflation of the balloon and removal of the inflation instrument. A balloon dispenser for housing a balloon prior to receipt of an inflation instrument is also described.
