  • Publication number: 20080065156
    Abstract: An apparatus, system, and method for repairing openings such as septal defects includes advancing a catheter to the site of the defect, grasping opposing edges of the defect, passing one or more suture lines through the opposing edges, tightening the suture lines, and deploying and expanding a fastener to secure the suture lines and close the defect. The fastener can include tissue-growth-inducing materials to encourage tissue growth onto or into the fastener and/or suture. The fastener includes a locking clip portion and a plug portion, which may be an expandable portion and/or tissue-growth-inducing portion.

  • Publication number: 20070225739
    Abstract: An elongate tubular body extends between a rotatable cutter and a control. The cutter is connected to the control with a rotatable element. A vacuum is applied through an annular passage defined between the tubular body and the rotatable element. The tubular body has a sufficiently small outside diameter and sufficient kink resistance and pushability to navigate through arteries such as the internal carotid artery.

  • Publication number: 20070073391
    Abstract: A system and method is provided for treating a mitral valve. The method preferably includes advancing a guide catheter to an ostium of the coronary sinus and advancing a delivery catheter containing a medical implant through the guide catheter and into the coronary sinus. The delivery catheter has an inner member on which the medical implant is held and an outer sheath which is retractable for deploying and releasing the medical implant. In one embodiment, the medical implant has proximal and distal anchors and a bridge containing resorbable material. The inner member may have a flexible sleeve for gripping and holding a portion of the outer sheath, thereby providing a releasable attachment mechanism. In another embodiment, the inner member may include an inflatable balloon having a tapered distal region which extends from the outer sheath for providing an atraumatic tip. The inflatable balloon may also be used to expand the medical implant and to grip the outer sheath.

  • Patent number: 6482217
    Abstract: An elongate tubular body extends between a rotatable cutter and a control. The cutter is connected to the control with a rotatable element. A vacuum is applied through an annular passage defined between the tubular body and the rotatable element. The tubular body has a sufficiently small outside diameter and sufficient kink resistance and pushability to navigate through the internal carotid artery and at least into the M3 segment of the middle cerebral artery.

  • Patent number: 6030405
    Abstract: A dilation catheter having a balloon inflation shaft with an inflation lumen into which a stiffening wire extends and a guidewire shaft having a guide wire lumen adjacent to the balloon. The stiffening wire includes at least two stepped diameter reductions along its length to vary stiffness from a stiff proximal end providing improved pushability to a less stiff distal end providing improved trackability. A manifold at the inflation shaft proximal end includes a handle for adjusting the distance the stiffening wire extends into the inflation lumen to allow stiffness to be optimized. The handle includes a tubular flange frictionally engaging the manifold to prevent inadvertent handle movement. The balloon inflation shaft and guidewire shafts are bonded together in a manner producing an assembly having a circular cross section for improved connection to a circular balloon and improved catheter performance.
