Body Entering Conduit Axially Movable Within Flexible Protective Sheath Facilitating Sterile Insertion Into Body Duct Patents (Class 604/171)
  • Patent number: 10383656
    Abstract: An introducer needle assembly including a compressible section between the rigid needle and the hub. Once the vessel is entered as determined by blood entering the syringe, the compressible section of the introducer needle is occluded by compressing the section with the thumb and a finger. Neither blood nor air can pass. Since the compressible section is in a flattened area it is easier to hold the needle while the syringe is unscrewed. The operator then can begin threading a guidewire down the device which is now easier to enter because blood is not coming out of the hub thus obscuring the lumen.

  • Patent number: 10265499
    Abstract: A urinary catheter system includes a catheter, a sheath, an enclosure and a plug. The catheter has distal and proximal ends. The sheath is slidable along the catheter between first and second positions. The enclosure encloses a majority of the catheter and includes a bottom member, a top member, an outer peripheral wall defining an outer hole to allow advancement of the distal end, and an inner peripheral wall defining an inner hole, where the catheter is extendable through the inner hole. Rotating the top or bottom member relative to the other member causes the catheter to wind within the enclosure. The plug can seal the proximal end to block liquid flow, and a user can disengage the plug to allow liquid flow.

  • Patent number: 9597066
    Abstract: Drug eluting vascular closure devices and methods for closing a blood vessel puncture site disposed at a distal end of a tissue tract are described. The devices and methods rely on a combination of the body's own natural mechanism to achieve hemostasis with chemical and/or biological agents to accelerate the hemostatic process. One method includes the steps of introducing a closure device through the tissue tract and deploying an expansible member at a distal end of the device within the blood vessel to occlude the puncture site. A chemical and/or biological sealing member disposed proximal the expansible member is then displaced so as to expose a chemical and/or biological region or release region of the device. At least one chemical and/or biological agent is thereafter released from the device and into the tissue tract to accelerate the occlusion process in the tract.

    Abstract: An apparatus having a tube section and an expanded end. The tube section is flexible while the end section is rigid. The apparatus has a central bore, large enough to loosely receive an endoscope tube, and the end section has two peripheral bores which communicate with the central bore. There is a collar around the central bore which allows formation of air- and water-tight seal with the head of an endoscope. The tube may be fenestrated at its proximal end and may include medial pleats. This apparatus is mainly used by: sliding an endoscope into the central bore until the endoscope head forms an air- and water-tight seal with the central bore; connecting a lavage tube to one peripheral bore and a vacuum tube to the other peripheral bore; inserting the endoscope and the apparatus into a GI tract; and manually controlling the apparatus to apply lavage and vacuum.

  • Patent number: 8936575
    Abstract: A needle tip shielding mechanism is described herein. The shielding mechanism comprises an outer housing, an inner housing, and a needle having a needle feature. Generally, the outer housing comprises at least one adapter-interlock feature. Moreover, the inner housing comprises a needle-feature capture mechanism, such as a washer feature, and a needle-tip capture mechanism, such as duckbilled tip barrier. In some cases, the inner housing is slidably moveable within the outer housing. In such cases, the inner housing is movable between a first position that biases the adapter-interlock feature into an engaged position and a second position that allows the adapter-interlock feature to move to an unengaged position. This ability to bias the interlock feature in the engaged position and to allow the interlock feature to move to the unengaged position allows the shielding mechanism to be selectively coupled to and released from an interlock-feature mating component within a catheter adapter.

  • Patent number: 8932262
    Abstract: The present invention provides a medical device for insertion into a body, the device having at least one surface covered by and attached to at least one detachable cover and at least one surface hole, such as the cover encapsulate and seals the medical device. The cover can be detached and pulled off the device which remains in the body. The cover includes at least one sealing element for preventing ingress of fluids between the cover and at least part of the medical device. The cover and the at least one sealing element, encapsulates the medical device though it's length, overlapping at least one surface hole. The cover and the at least one sealing element are designed to isolate at least one hole from at least another holes, while enabling free passage through it, in at least partial time period in which the medical device is within the body.

  • Publication number: 20140350524
    Abstract: A tool for engaging and withdrawing a wire guide from a patient includes a deformable distal segment having a self-expanding bias such that the distal segment assumes a tortuous configuration, and a control line attached to the distal segment and configured to extend through an intraluminal sheath, such that pulling the control line deforms the distal segment in opposition to the self-expanding bias to tighten about a wire guide. The tool may be withdrawn from the patient while tightened about the wire guide, such that the wire guide simultaneously extends out of the patient at each of a first and a second percutaneous entry point.

  • Patent number: 8888747
    Abstract: A catheterization device with vents is disclosed which serves to prevent a build-up of air pressure within a closed protective sheath. The vents may be in the form of small openings and may be situated at the distal portion of the catheterization device. The small openings may optionally be covered. They may be on the protective sheath itself or they may be on a distal terminus body connected to the protective sheath. Sample openings include an attached valve which connects the inside of the protective sheath with the external environment, a gas permeable membrane, or a slitted membrane forming 4 flaps.

  • Publication number: 20140316214
    Abstract: Devices and methods for performing in vitro fertilization (“IVF”) and maximizing successful fertilization rates by optimizing the fluid flow conditions under which zygotes are transferred from growth medium to the uterine wall. The apparatus has a control unit with an external port and an internal pump for creating positive and negative fluid pressure at the port. A flexible extension hose connects the port to an inter-uterine catheter assembly. The catheter assembly has an inner catheter and an outer sheath surrounding the inner catheter. The control unit includes a programmable microprocessor that accepts input commands and controls operation of the pump. Optionally, the control unit has remote control means for activating, de-activating, and reversing the flow of the pump. The control unit can be programmed to repeatedly provide the same aspiration and expulsion flow conditions through the catheter assembly.

    Abstract: An improved splittable medical device introducer designed to introduce a medical device such as a lead or catheter, into a patient's vasculature without loss of blood or introduction of air is described. The introducer assembly is designed with a notch provided at the proximal end of the introducer housing. The notch, which may comprise a multitude of cross-sectional geometries, is designed to reduce the force required to separate the housing and the introducer sheath, thereby minimizing the possibility of unintentional dislodgement during separation. The notch also increases the repeatability and consistency of the amount of force required to separate the introducer housing and sheath.
