  • Patent number: 10065017
    Abstract: An elongate catheter tip may be coupled to an elongate catheter body adjacent a distal end of the catheter body. To couple a catheter tip to a catheter body, a proximal portion of the catheter tip may (1) be disposed between a first elongate member and an second elongate member and (2) be subsequently fused to the second elongate member and the first elongate member. The resulting catheter and catheter tip may, among other functions, facilitate the measurement of differences in fluid pressure and/or facilitate the delivery of fluid or medical devices during a medical procedure.

The thermoset polyimide has a very high glass transition temperature (Tg) of approximately 400° C. (as measured by differential scanning calorimetry), and excellent dimensional stability at the processing temperature of polyamides commonly used in catheter components. As a result, during formation and assembly of the catheter, production of a thin polyimide layer with controlled dimensions is facilitated. The polyimide has a high modulus and provides a thin walled yet highly pushable shaft section, while the second layer provides kink resistance. In one embodiment, the second material is selected from the group consisting of a polyamide material and a polyurethane material.

The obturator then further expands the pathway and delivers the dilator assembly to the desired location. The safety needle assembly, obturator assembly, and blade assembly are removed, leaving the dilator assembly in place for future procedures.

  • Patent number: 9692557
    Abstract: Apparatus and methods for administering treatment within a bodily duct of a patient. According to one implementation a treatment catheter having an expandable structure disposed at an end thereof is provided that includes an elongate hollow shaft having a one or more first through holes and one or more second through holes spaced axial apart, the one or more first through holes residing beneath the expandable structure. A sleeve positioned along an outer surface of the hollow shaft is moveable between first and second axial positions to respectively permit or inhibit the flow of a treatment agent through the one or more second through holes into the bodily duct. An elongate wire having a seal unit is positioned within an inner lumen of the hollow shaft.

  • Patent number: 9681974
    Abstract: Transoral obesity treatment devices and related methods for operation thereof are described which occupy space within a stomach and/or stimulate the stomach wall. The transoral obesity treatment devices and related methods are intended to assist a patient in maintaining a healthy body weight. Features of the devices include insertion transorally and without invasive surgery, without associated patient risks of invasive surgery, and without substantial patient discomfort. The life span of these devices may be material-dependent upon long-term survivability within an acidic stomach, but is intended to last one year or longer. The devices have the capacity to vary in size and are desirably self-actuating in that they change shape and/or volume using internal motors or actuators. The changing character of the devices helps prevent the person's stomach from compensating for the implant, such as sometimes happens with static intragastric devices.

  • Patent number: 9662432
    Abstract: A novel arterial cannula tip includes an elongated body having an expanded four-lobe swirl inducer and a diverging diffuser. The swirl inducer presents micro-scale blood-wetting features that help to enhance the jet or core of the flow of blood sufficiently to delay the onset of turbulence and facilitate a strongly coherent blood outflow jet as it enters the cannulated artery, while the diverging diffuser reduces exit force and promotes and laminar flow which mitigates intimal vascular damage owing to high wall shear stresses at regions of jet impingement. When used in conjunction with an aortic cannula, the device facilitates neuroprotection by way of improved cerebral perfusion.

    Abstract: A system may comprise a clot engagement element having a collapsed delivery configuration and an expanded configuration for engaging with a clot and for dislodging the clot from a first vessel segment. An elongate member may be configured to apply a pull force to the clot engaging element to dislodge the clot from the first vessel segment. A clot removal catheter may include a lumen at its distal end sized to receive the clot and configured to maintain a stable position in a second blood vessel segment proximal of and larger in diameter than the first blood vessel segment. A distal end of the elongate member may be configured to protect a third blood vessel segment between the first and second blood vessel segments from tractive forces transmitted by the elongate member during clot dislodgement from the first vessel segment.

  • Patent number: 9629998
    Abstract: Implantable medical leads and implantable lead extensions include a shield. The implantable medical lead is coupled to the implantable lead extension. Stimulation electrodes of the implantable medical lead contact stimulation connectors within a housing of the implantable extension to establish a conductive pathway for stimulation signals from filars of the implantable extension to filars of the implantable medical lead. Continuity is established between the shield of the implantable medical lead and the implantable extension by providing a radio frequency conductive pathway within the housing. The radio frequency conductive pathway extends from a shield of the implantable extension to a shield connector that contacts a shield electrode of the implantable medical lead. The radio frequency conductive pathway may have various forms such as a jumper wire or an extension of the shield within the implantable extension.

    Abstract: A method of bridging from a wound dressing to a wound port for negative pressure wound therapy includes positioning an elongate wick between a wound and a remote location with respect to the wound. The elongate wick includes a three-dimensional spacer fabric having an upper fabric layer spaced from a lower fabric layer by an intermediate layer of pile threads. The elongate wick is covered with a flexible wick cover such that an enclosure is formed around the elongate wick. A substantially fluid-tight seal is established between a first end of the elongate wick cover and the wound dressing such that a reservoir is defined over the wound in which a negative pressure may be maintained. A substantially fluid-tight seal is established between a second end of the elongate wick cover and a fluid port configured for connection to a source of negative pressure.
