摘要:
Delivery devices for placement of therapeutic devices relative a heart valve annulus of a beating heart that are delivered to the heart via minimally invasive surgical procedures and can be used in the heart during a therapeutic procedure that can be visualized in real time and be guided to specific locations within the heart. The systems and methods can be used to determine the exact location of the implantation delivery devices and therapeutic devices relative to a valve annulus and to determine that any therapeutic device is implanted in the correct location.
摘要:
An image guided navigation system for mapping at least one of the shape, size and location of a structure within a heart of a patient, including a catheter system having a first catheter with a longitudinally extending lumen, a second catheter having a longitudinally extending lumen and positioned at least partially within and moveable relative to the lumen of the first catheter, an elongated member positioned at least partially within and moveable relative to a lumen of the second catheter, a first detectable marker located at a generally distal end of the first catheter, a second detectable marker located at a generally distal end of the second catheter, and a third detectable marker located at a generally distal end of the elongated member, wherein at least one of the three detectable markers is axially moveable relative to at least one of the other detectable markers.
摘要:
Visualization reference devices to aid in non-direct visualization of heart structure. The devices are positionable in the heat structure and visible with a desired imaging modality. The devices being elastically transformable between delivery configurations and deployment configurations. The devices being used to assist a clinician in mapping the heart structure while implanting therapeutic devices therein. An example would be using the devices disclosed herein to map the size, location, orientation and displacement of a mitral valve annulus for catheter based implantation of a valve repair device.
摘要:
Device, system and method for drawing together patient tissue. A central hub has an axis. Several tines are coupled to the central hub. Each of the tines has a tip and is resiliently biased to form a coil. Each tip points radially outward from the axis, with an approximately common angle between adjacent ones of the tines.
摘要:
Incompetency or regurgitation of a cardiac valve is treated by injecting a space occupying material or implanting a space occupying device within a papillary muscle or in heart tissue near a papillary muscle to cause lengthening or repositioning of the papillary muscle in a manner that improves coaptation of the valve leaflets and lessens valvular incompetency or regurgitation. The procedure may be performed by open thoracotomy, thoracoscopically, by a tran-endocardial catheter based approach or by a trans-coronary catheter based approach.
摘要:
Methods and systems for improving the competency of a venous valve wherein one or more compressor(s) (e.g., space occupying material(s) or implantable device(s)) is/are delivered to one or more location(s) adjacent to a venous valve to compress the venous valve in a manner that causes one or both leaflets of the valve to move toward the other, thereby improving closure or coaptation of the valve leaflets. The compressor(s) may be delivered by an open surgical approach, by a direct percutaneous approach or by a transluminal catheter-based approach.
摘要:
System (10) for treating a dilated heart valve includes a dilivery device. Tension device (12) is slidably received within the lumen of delivery device (14) for delivery to and deployment at the treatment area. Delivery device (14) includes a plurality of arranged catheters including an inner catheter (26) within the lumen of an outer catheter (22). Tension device (12) includes a first anchor (16) attached to a second anchor (18).
摘要:
A surgical fastener clip for proximating tissue, the clip providing an undeflected state in which the clip comprises a center portion, a first leg, and a second leg. The center portion has a perimeter defining a circle-like shape. The legs project outwardly relative to the perimeter from a point of departure to a tip. Extension of each of the legs relative to the perimeter defines an identical wind direction that is either clockwise or counterclockwise. The clip optionally includes a linear cross-member extending across the perimeter. The surgical clip can be formed by a wire that is partially wound onto itself in a spiral-like fashion, with the center portion and the legs being co-planar in the undeflected state. During use, the clip is rotated, drawing tissue into the center portion. Systems incorporating the clip are also provided.
摘要:
Incompetency or regurgitation of a cardiac valve is treated by injecting a space occupying material(s) or implanting a space occupying device(s) at an interstitial location adjacent to the valve such that the space occupying material or device exerts pressure on the valve causing one or more leaflets of the valve to be favorably repositioned. The procedure may be performed by open thoracotomy, thorascopically or transluminally using a tissue penetrating catheter.
