  • Publication number: 20200323664
    Abstract: Medical devices that include a tubular member with a plurality of braided filaments, each filament crossing another of the filaments at a respective crossing point forming sidewall and a plurality of pores in the sidewall that are sized to inhibit flow of blood through the sidewall into an aneurysm to a degree sufficient to lead to thrombosis and healing of the aneurysm when the tubular member is positioned in a blood vessel and adjacent to the aneurysm, the pores have an average pore size that is less than or equal to about 500 microns when the tubular member is in an expanded state, the filaments possessing antithrombogenic surfaces to increase antithrombogenicity of the medical device with pores substantially free of webs formed by antithrombogenic material, such that fewer than 5% of the crossing points have webs formed by antithrombogenic material thereby permitting the pores to be substantially free of webs.

  • Publication number: 20200139023
    Abstract: A wound dressing apparatus includes a wound dressing member dimensioned for positioning relative to a wound bed. The wound dressing member including an internal vacuum reservoir and has a port in communication with the vacuum reservoir for applying subatmospheric pressure to the vacuum reservoir to facilitate removal of fluid from the wound bed. The wound dressing member includes a visual pressure indicator associated therewith for indicating a level of pressure within the vacuum reservoir. The visual pressure indicator includes color indicia having a plurality of colors corresponding to a condition of the pressure within the vacuum reservoir. The wound dressing member includes a lower absorbent member positionable adjacent the wound bed and an upper member which at least partially defines the vacuum reservoir. At least one of the top member and the lower absorbent member has the visual pressure indicator mounted thereto.

  • Publication number: 20190247553
    Abstract: A composite wound dressing apparatus promotes healing of a wound via the use of a micropump system housed within or above a wound dressing member. The micropump system includes a miniature pump that applies a subatmospheric pressure to the wound to effectively draw wound fluid or exudate away from the wound bed without the need for a cumbersome external vacuum source. Hence, the wound dressing and micropump system is portable which allows the patient mobility that is unavailable when an external vacuum source is used. The patient does not need to be constrained for any period of time while exudate is being removed from the wound.

  • Publication number: 20190008668
    Abstract: A stent delivery system can include a core member, an introducer sheath, and a microcatheter. The core member can have a distal segment. The stent engagement member can have a generally tubular body positioned about the core member distal segment and can be rotatably coupled to the core member. The engagement member can include an inner layer that has a first durometer and an outer layer that has a second durometer less than the first durometer. The stent can extend along the core member distal segment such that an inner surface of the stent is engaged by the engagement member outer layer for facilitating rotation of the stent relative to the core member.
