  • Patent number: 9504491
    Abstract: A method is provided including introducing a delivery device through a vessel wall to a treatment site within one of a peri-adventitial space or a pericardium adjacent a coronary blood vessel and delivering a treatment agent through the delivery device. The treatment agent is delivered through the delivery device according to conditions that hydraulically dissect tissue planes within the peri-adventitial space. A kit is provided including a delivery device having a needle to be advanced through one of an epicardium of a heart and a wall of a coronary blood vessel into a peri-adventitial space and a treatment agent comprising particles having an average diameter on the order of 15 microns or more to be delivered through the delivery device into the peri-adventitial space.

  • Patent number: 8858611
    Abstract: Sterilization methods for implantable prostheses are described where a polymeric stent may be sterilized, e.g., via ETO sterilization, at a temperature below a glass transition temperature of the stent. A separate delivery catheter may be sterilized separately and the stent and delivery catheter may then be combined in an aseptic or semi-aseptic environment and sterilized as an assembled system such that the requirements for sterilizing the system are relatively lower. Additionally and/or alternatively, valve and filter assemblies may be used with an optional mandrel assembly for maintaining sterility of the internal components of a catheter system.

  • Publication number: 20110046709
    Abstract: Various methods for implanting a stent into an ostium or a proximal portion of a body vessel utilizing a guide catheter, rather than a convention balloon angioplasty balloon catheter, as the primary delivery device are disclosed. The guide catheter can be used as the primary stent delivery catheter for the ostium region of the body vessel and can be anchored to the vessel to allow secondary treatment devices to be advanced to distal locations in the body vessel.

  • Patent number: 5397310
    Abstract: A catheter introducer sheath assembly, for introduction into a body passage of a catheter containing a filter comprises a flexible introducer sheath joined to the distal end of a closure device forming a through-passage with a diameter sufficient to pass the catheter therethrough. The closure device has a resilient member in the through-passage and two rotatable body portions, one stationary with respect to the resilient member, and the other rotatable about the axis of the resilient member with an internal cam circumferentially spaced around the axis. A compression member positioned radially in an extending aperture makes contact with both the resilient member and the cam surface to vary the through-passage allowing the operator to manually control the passage of the device. The sheath assembly receives a cathetory guidewire that slides through and extends beyond the closure device and the sheath.

  • Patent number: 5242462
    Abstract: A filter device positionable within a blood vessel for trapping blood clots in that vessel, the filter device comprising a head with a plurality of divergent legs each secured at its proximal end, to the head, each leg having a hook arranged at its distal end.Each leg has a radially outwardly directed radius of curvature to create a conical configuration to the filter assembly, while distributing the stress concentration along the length of the bend, so that the elastic limit of the material, stainless steel in this embodiment, is not exceeded, and which permits compact delivery of the filter, and adequate radially directed force to permit slight hook penetration of a vessel wall.
