  • Patent number: 10709868
    Abstract: A hemodialysis curved split-tip catheter comprises an elongated portion, a proximal end and a distal end defining a longitudinal axis. The proximal end attaches to a hub with suture wings assembly, which in turn connected to extension tubings. The distal end has two distal tip segments splitted from each other. The distal tip segments bend longitudinally inward toward a centerline of a blood vessel. First distal tip segment has a smaller angle, with respect to the axis extended from the dividing point longitudinally parallel to a centerline axis of a blood vessel, compare to second distal tip segment. This configuration to make the distal end of the catheter to be located not at the centerline axis of a blood vessel.

In some embodiments, a drug delivery system can be configured to use a combination of infusion and aspiration to control delivery of a drug to a patient. Catheters, controllers, and other components for use in the above systems are also disclosed, as are various methods of using such systems.

  • Patent number: 9675786
    Abstract: The invention provides devices with specialized ends for diverting fluids trapped in an organ. In a first group of embodiments, the invention provides implantable devices that shunt fluid trapped in a patient's organ to its normal physiological destination. In a second group of embodiments, the invention provides devices with specialized ends for connecting the devices to conventional medical tubing to divert fluid trapped in an organ to a destination selected by the practitioner. The invention further provides systems and methods of using the devices.

  • Patent number: 9669188
    Abstract: A noncircular inner lumen guiding catheter with assisted variable support has an inner wall defining a noncircular cross-sectional shaped lumen for use in delivery of multiple microcatheters or other devices for treatment of neurovascular defects, such as for treatment of aneurysms. The noncircular inner lumen guiding catheter with assisted variable support includes torque transmittal guidance walls that are flexible linearly but not circumferentially, and that are neither collapsible nor kinkable. The noncircular shaped cross-section of the inner lumen may extend along the entire length of the catheter or a portion thereof, including distal or proximal.

  • Patent number: 9623603
    Abstract: A conduit, such as an introducer sheath, catheter, or guide catheter, incorporating two or more separate lumens to prevent the entanglement of guidewires located at least partially within the conduit. The lumens are separated by at least one disruptable barrier that allows multiple lumens to be converted into fewer lumens prior to or as a device is advanced through the introducer sheath.

  • Patent number: 9603601
    Abstract: An occlusion device may comprise a first tube having a first balloon positioned at a distal end, and a second tube having a second balloon positioned at a distal end. The first balloon may be sized and configured to occlude a vascular lumen upstream of a vascular puncture, and the second balloon may be sized and configured to simultaneously occlude the vascular lumen downstream of the vascular puncture. A method of occluding a vascular puncture may comprise positioning a distal end of an occlusion device comprising a first balloon and a second balloon through the vascular puncture and into a vascular lumen. The first balloon may be positioned downstream of the vascular puncture, and the second balloon may be positioning upstream of the vascular puncture.

  • Patent number: 9539382
    Abstract: A stepped catheter comprising a distal portion of smaller diameter than a proximal portion, wherein the distal portion defines a flow aperture configured to deliver fluid passing through the catheter from the proximal portion to the flow aperture. The catheter may include a flow restrictor located within a lumen of the catheter at or near the flow aperture. A filter element may also be included and located within the lumen of the catheter at a location upstream of the flow restrictor.

  • Patent number: 9427552
    Abstract: One embodiment is an improved method for providing a tube for attachment to a medical device such as a catheter that provides for intermittent changes in tube path length as a result of body movement thereby reducing the stress and pain caused by pulling on the device, as well as the optional provision to provide a very low, controlled tension that provides improved stability of the medical device without damage to the surrounding body tissues. In at least one embodiment, there is a decrease in infection risk by the patient. This controlled tension can be applied or removed intermittently by a medical practitioner or the patient. Other embodiments provide for extension in tubal path length while simultaneously providing for intermittent or continuous low tension pull on the catheter. Provision is also made for a continuous smooth fluid path with no moving internal parts.
