  • Publication number: 20200276432
    Abstract: An introducer for insertion of a medical device into a patient's vasculature includes an elongate introducer body, a hub, and a hemostatic valve. The elongate introducer body includes a longitudinal axis, a proximal region, a distal region, and an inner lumen. The hub is coupled to the proximal region of the introducer body. The hemostatic valve is disposed within the hub and forms a liquid-tight seal across the inner lumen. The introducer includes a guide configured to guide an object towards the center of the valve during insertion of the object.

  • Publication number: 20170312492
    Abstract: A system for providing vascular access in a patient's body may comprise at least one hemostatic valve (610) and at least one clamp (210) to be used with a vascular graft (110). The vascular graft (110) comprises a tubular body having a proximal end (110A) and a distal end (110B), the proximal end (110A) being configured to be attached to a vessel in a patient's body. The at least one valve (610) is configured to be attached to the distal end (110B) of the graft's tubular body and comprises a housing (616) including a flexible membrane (611) that allows a medical device (810) to be inserted through the membrane (611) into said vascular graft (110). The valve (610) further comprises an introducer sheath (615) configured to be inserted into the distal end (110B) of the graft's tubular body.

  • Publication number: 20170215918
    Abstract: A cannula supporting a percutaneous pump can include a proximal section with a first flexural modulus. The cannula can include one or more distal sections with a flexural modulus that is different than the first flexural modulus. The material and its arrangement along the length of the cannula can be selected so as to influence bending properties. This can, for example, allow efficient positioning of the cannula in a desired location without displacing the guidewire.

  • Patent number: 6641776
    Abstract: X-ray imageable articles, for instance surgical implements or parts therefore which are used in minimally invasive surgical procedures, may be prepared by a process including the steps of: (a) preparing a mixture composition comprising: i) radiolucent particulate material selected from ceramic materials, metallurgic materials, and combinations thereof and having a particulate size of no more than 40 microns, ii) radiopaque particulate material selected from ceramic materials, metallurgic materials, and combinations thereof and having a particulate size of no more than 40 microns, and (iii) at least one polymeric binder material; (b) injection molding the mixture composition into a preform; (c) optionally removing the binder material from the preform; and (d) sintering the preform.
