Abstract: A tissue opening occluder comprising first and second occluder portions, each occluder portion including a frame structure and an attachment structure to attach one portion to the other portion. The frames may be utilized to constrain the tissue between the two portions enough to restrict the significant passage of blood therethrough. The frame portions may be covered by a fabric suspended from a perimeter thereof. The occluder portions are conjoined at least one point on each portion.

Abstract: An elongate tubular body with a rotatable cutting element is provided. An opening is provided near the distal end of the tubular body, and the cutting element may be partially exposed through the opening. The cutting element is configured to remove plaque from the wall of a body lumen. A distal segment may coupled to the distal end of the tubular body and may have a distal port for slidably receiving a guidewire therethrough.

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.

Abstract: A patent foramen ovale closure device, method of delivering and a delivery system are provided. The device may include a closure device releasably connectable to an actuator. The device may include a proximal segment, an intermediate segment and a distal segment. When delivered, the proximal segment and intermediate segment form a first clip-shaped portion sized and configured to be positioned over a septum secundum of the patent foramen ovale, and the intermediate segment and distal segment form a second clip-shaped portion sized and configured to be positioned over a septum primum of the patent foramen ovale.

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 cutter has at least one radial projection which cooperates with at least one stationary element on the tubular body to cut material drawn into the tubular body. Material that has been processed by the cutter is aspirated through the tubular body for disposal.

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 control has an indicator that reveals resistance to rotation and/or reduction in flow. Material that has been processed by the cutter is aspirated through the tubular body for disposal. The control enables rotation of the rotatable element only following application of a predetermined level of vacuum.

Abstract: A release assembly is provided to aid the reversible and repositionable deployment of a defect occluder. The release assembly includes an occluder tether having a distal portion comprising at least one suture loop, and a snare structure having a distal portion comprising a snare element. The at least one suture loop is receivable through at least a portion of the defect occluder, and reversibly looped over an anchor element so as to permit reversible collapse the defect occluder for selective ingress and egress from a delivery catheter. The snare element is reversibly engageable with the anchor element so as to reversibly retain the at least one suture loop upon the anchor element, and thereby hold the defect occluder in a posture for reversible free-floating tethered deployment in a defect while being observable in a final position prior to release.

Abstract: Disclosed is an occlusion device for use in a body lumen such as the left atrial appendage. The occlusion device includes an occlusion member and may also include a stabilizing member. The stabilizing member inhibits compression of the left atrial appendage, facilitating tissue in-growth onto the occlusion member. Methods are also disclosed.
