  • Patent number: 9125801
    Abstract: Devices, systems and methods are disclosed for providing a direct visual indication of the relative inflationary condition of the balloon on a balloon catheter after insertion into the patient. In certain exemplary embodiments, a gastrostomy tube catheter is disclosed having a fluid feeding lumen and a balloon inflation lumen, a balloon communicating with the balloon inflation lumen, and an indicator strip having one end fixedly attached to the balloon and a free end movable along the length of the tube in accordance with the relative inflation and deflation of the balloon. The presence of the free end of the strip along an exposed portion of the gastrostomy tube serves as a direct visual indicator of a deflated condition of the balloon.

  • Patent number: 9101706
    Abstract: A fluid delivery device comprises a housing having a fluid reservoir. A needle is in fluid communication with the fluid reservoir in an engaged position and out of fluid communication with the fluid reservoir in armed and storage positions. A proximal end of a biasing member is coupled to the housing and a distal end of the biasing member is configured to deliver a force to the fluid reservoir. A piston member extends through the biasing member and is coupled to the distal end of the biasing member. The piston member is fixed with respect to the housing in a locked position such that the biasing member does not deliver the force to the fluid reservoir and moveable with respect to the housing in a released position such that the biasing member delivers the force to the fluid reservoir. Transitioning the needle from the storage position to the armed position transitions the piston from the locked position to the released position.

  • Patent number: 9066685
    Abstract: Methods and devices are disclosed that, in various embodiments and permutations and combinations of inventions, diagnose and treat Multiple Sclerosis or associated symptoms. In one series of embodiments, the invention consists of methods and devices for identifying patients whose Multiple Sclerosis or associated symptoms are caused or exacerbated, at least in part, by blockages of one or more of the patient's internal jugular veins (IJV) or azygous veins (AZV). In some instances, stenoses or other flow limiting structures or lesions in the patient's affected veins are identified. Further, in some instances the nature of such lesions and whether there is a significant disruption of blood pressure, or both, is ascertained. In some embodiments, methods and devices for applying one or more therapies to the blockages in the patient's IJV or AZV veins are provided.

  • Patent number: 9033926
    Abstract: An intravascular needle and catheter arrangement that ensures flashback is indicated after the catheter is safely inserted through the needle puncture in the vascular wall and emplaced into the vessel. This placement location, at which flashback first occurs is sufficient to begin threading the catheter without risk of over-insertion or under-insertion. The catheter overlies a needle having a distal tip that defines a point. The needle tip includes an enclosed distal-most end and a port located along at least one of the proximal portion of the point and an adjacent cylindrical sidewall of the needle. The distal end of the catheter exposes the port for entry of blood from a vessel thereinto only after the distal end of the catheter has entered sufficiently into the interior of the vessel. An opposing second side of the tip defines a curved surface that prevents puncturing of the back vessel wall.

  • Patent number: 8968252
    Abstract: An integrated vascular delivery system having a frame configured to receive a catheter insertable in a patient to deliver fluid at an insertion site. The frame includes a first hub, a second hub, and a pair of flexible lateral members extending between the hubs and including a tubular lateral member. The system also includes a fluidic channel that fluidically communicates with the catheter, wherein the fluidic channel passes through the tubular lateral member and at least one of the hubs, and includes a fixed turnabout portion in which fluid flows in a direction different from that within the catheter. The first and second hubs provide anchoring points on the patient distributed around the insertion site and on opposite ends of the catheter, thereby anchoring the frame to the patient and stabilizing the catheter. A method is provided for using an integrated vascular delivery system.

  • Patent number: 8968253
    Abstract: A catheter securement device includes a flexible base member having an adhesive side and an opposite non-adhesive side. A elastomeric anchoring member is mounted on the nonadhesive side of the base member. The anchoring member integrally includes a body attached to the base member, a pair of opposing pull tabs freely extending outwardly from the body, a keeper disposed in each of the pull tabs, and a T-shaped strap freely extending from the body.] The T-shaped strap terminates in a pair of opposing heads that are disposed generally parallel to the pull tabs. Pulling the opposing pull tabs opens the keepers for receiving the heads of the T-shaped strap, and the heads of the T-strap are selectively insertable into the keepers for securing a catheter between the anchoring member body and the strap.

  • Patent number: 8894679
    Abstract: A surgical device mitigates over-puncture with a bias spring that biases a leading, cutting edge in the opposite direction of the anticipated over-puncture. An associated locking mechanism is configured to release the force of the bias spring in a direction counter to the direction of insertion when the tension force of tissue against the cutting edge is released. Thus, when an opening in the tissue forms, the tension is released and the cutting edge can move opposite to the direction of insertion of the surgical device at the same time that an applied force drives the instrument in the direction of insertion. In this manner, the spring and locking mechanism cooperate to move the cutting edge opposite to the direction of insertion as soon as an incision is made.
