  • Implant delivery assembly with expandable coupling/decoupling mechanism
    Patent number: 6849081
    Abstract: An occlusive implant delivery assembly includes a rapid response decoupling or detachment mechanism that does not effect significant migration of the implant during release. The assembly includes an occlusive implant device, such as an embolic coil, a pusher or device to carry the implant to the selected location, and an expandable coupling-decoupling mechanism for releasing the implant at the selected site. The mechanical construction provides rapid release times. In addition, the releasing mechanism generally operates without exerting any significant force on the implant, thereby avoiding any significant displacement of the implant during release.

  • Surgical instruments and procedures for stabilizing the beating heart during coronary artery bypass graft surgery
    Publication number: 20040230099
    Abstract: The invention is methods and devices which a surgeon may use to stabilize the beating heart during a surgical procedure on the heart. Pursuant to the invention, a stabilizing device is introduced through an opening in the chest and brought into contact with the beating heart. By contacting the heart with the device and by exerting a stabilizing force on the device, the motion of the heart caused by the contraction of the heart muscles is effectively eliminated such that the heart is stabilized and the site of the surgery moves only minimally if at all. Typically, in separate steps, the surgeon contacts the heart with the stabilizing means, assesses the degree of movement of the anastomosis site, and exerts a force on the stabilizing means such that the contraction of the beating heart causes orgy minimal excess motion at the surgery site.

  • Methods and devices for protecting a passageway in a body when advancing devices through the passageway
    Publication number: 20040230285
    Abstract: A liner is advanced through a narrowed region in a vessel such as the internal carotid artery. The liner is advanced through the narrowed region in a collapsed position. A stent is then advanced through the liner and expanded to open the narrowed region. The liner may also have an anchor which expands an end of the liner before the stent is introduced.

  • Aortic occlusion balloon cannula
    Publication number: 20040162519
    Abstract: A multi-lumen cannula device is provided having an occlusion balloon for partitioning a vessel, such as the aorta during a CPB procedure. The cannula has a first lumen for delivering fluid to a location distal to the balloon, a second lumen for delivering fluid to a location proximal to the balloon, and an inflation lumen through which the balloon may be inflated. In certain embodiments, the cannula has a flexible proximal portion and a more rigid distal portion maintained at an angle thereto. The distal and proximal structures of the balloon facilitate reliable balloon positioning and occlusion within the vessel.

  • Access platform for internal mammary dissection
    Patent number: 6746467
    Abstract: An access platform having a first and a second blade interconnected to a spreader member that laterally drives the blades apart or together and support pads interconnected to a blade. A torsional member is operably interconnected to a blade and the spreader member and is used to vertically displace the interconnected blade and, thus, increase a surgeon's working space and visual access for the dissection of an internal mammary artery. A tissue retractor interconnected to the blades and is used to draw the soft tissue around an incision away from the surgeon's working area.

  • Containers and methods for delivering vaso-occluding filaments and particles
    Publication number: 20040098024
    Abstract: Containers for holding and delivering vaso-occluding materials, such as hydrogel particles and filaments include a fluid inlet port and a fluid outlet port that are respectively fluidly connectable with a fluid source and a delivery catheter. The vaso-occlusive materials may be held in the container in a hydrated or unhydrated state. The container further includes at least one chamber or passageway extending therebetween. The passageway may be straight, curved, spiral, helical, narrow or otherwise shaped. The chamber may also have sections of varying cross section such as a ramped section. The shapes of the passageways of the container help organize ejection of the vaso-occluding materials minimizing contamination and clumping.

  • Surgical instruments and procedures for stabilizing the beating heart during coronary artery bypass graft surgery
    Patent number: 6673013
    Abstract: Methods and devices used to stabilize a beating heart during a surgical procedure on the heart and to expose a surgical site are disclosed. The stabilizing device is introduced through an opening through the chest and brought into contact with the beating heart, and by exerting a stabilizing force on the device, the motion of the heart caused by the contractions of the heart muscles is effectively eliminated. Exposure members are actuable to reposition a portion of the surface of the heart to better expose a target artery or other surgical site. Accordingly, the heart is stabilized and movement of the site of the surgery is minimized.
