  • Patent number: 11103373
    Abstract: The present invention is directed to a deployment system for an endoluminal device. The deployment system includes a confining sheath placed around a compacted endoluminal device. A deployment line is provided in the system. As the deployment line is actuated, the sheath retracts from around the compacted endoluminal device. Once the sheath is retracted from around the compacted endoluminal device, the endoluminal device is operable to expand. Any remaining sheath material is removed from the implantation site along with the deployment line.

Pathogenic biofilms dissolve and bacteria colony counts decrease at lowered temperatures in body cavities, and infectious, temperature sensitive organisms (fungi, yeast, bacteria, viruses, parasites, and protozoans) become dormant, change morphology, or cease growing under the same lowered body cavity temperatures.

  • Patent number: 10625050
    Abstract: An introducer used to provide a route through which a catheter or other medical device is inserted so as to gain access to a subcutaneous vessel of a patient is disclosed. The introducer is configured so as to minimize the amount of force needed to enter and dilate a vessel, thus reducing trauma to the vessel and the patient. In one embodiment, an introducer is disclosed, comprising a sheath and a dilator. The sheath includes a tubular portion that defines a lumen. The dilator includes an elongate body and a tapered distal tip and is configured to be removably disposed within the lumen of the tubular portion of the sheath. The dilator elongate body defines a cylindrical recess proximally extending from the tapered distal tip. The cylindrical recess configured to receive therein the tubular portion of the sheath when the dilator is disposed within the tubular portion of the sheath.

  • Patent number: 10595899
    Abstract: Automatic dilator devices for generating minimally invasive access apertures for surgical procedures or endoscopic surveillance. The automatic dilators comprise a number of spreader tubes nested one inside the other. The devices deploy automatically by means of coupled mechanical mechanisms which insert one spreader after the other distally into the patient's tissue. Each spreader moves distally into the tissue by means of a screwing action, by which rotation is converted into linear motion of the neighboring spreader, immediately external to it, by means of interaction between a helical thread form on a surface of a spreader being engaged by a section of thread, or by one or more protrusions on the opposing face of the next spreader external to the rotating spreader. Such a combination of helical thread and follower enables a rotatory mechanism to be used to deploy one nested spreader tube after the other, by continuous rotary motion.

  • Patent number: 10561509
    Abstract: A self-expanding braided stent includes at least a distal radial expansion ring added to a distal end of the stent body to increase a radial expansion force of the self-expanding braided stent in deployment of the stent, and to facilitate advancement of the stent through a delivery sheath by a core advancement wire. A proximal radial expansion ring is optionally added to a proximal end of the stent body to allow the stent to be recaptured following partial deployment by retraction of the core advancement wire, prior to full deployment of a proximal portion of the stent body.

  • Patent number: 10537452
    Abstract: A stent delivery system can include a core member, first and second restraints, and a stent engagement component. The core member can have a distal segment. The first and second restraints can be coupled to the core member distal segment and axially spaced apart from each other to provide an axial gap. The first and second restraints can each have an outer profile that tapers radially inwardly in directions away from the gap. The stent engagement component can be at least partially disposed in the axial gap between the first and second restraints such that the component is slidably and rotatably coupled to the core member distal segment.
