Heart valve prosthesis using different types of living tissue and method of fabricating the same

Номер: US20120010697A1

Автор: Chang-Ha Lee, Cheul Lee, Eun Ae Jo, Hong-Gook Lim, Kang Sun Hong, Kyong-Min Shin, Sam Sea Oh, Yong-Jin Kim

Принадлежит: Taewoong Medical Co Ltd

A heart valve prosthesis and a method of fabricating the same. The heart valve prosthesis uses a leaflet of pig pericardium or a leaflet of cattle pericardium, which has a suitable thickness according to the size of the valve, and a stent. The heart valve prosthesis is fabricated by placing a valve body over a Dacron body, binding the valve body to the Dacron body using stitching fiber, rolling the Dacron body into a cylindrical form such that the valve body is located inside, binding opposite edges of the Dacron body to each other using stitching fiber, and inserting the resultant structure into a stent, which is knitted using a shape memory alloy wire. The heart valve prosthesis is friendly to and is not rejected by human tissue, is free from deformation, and can be implanted using a non-invasive manner without incising the chest wall of a patient.

An orientation guide comprising a housing arranged to couple to a surgical instrument. In one embodiment the orientation guide further comprises first and second indicators ( 22, 26 ). The first indicator ( 22 ) is pivotally coupled to the housing ( 20 ) such that the first indicator ( 22 ) can rotate relative to the housing ( 20 ) about a first axis ( 24 ) to maintain its angular position about the first axis ( 24 ) relative to a vertical axis irrespective of movement of the housing ( 20 ). The second indicator ( 26 ) surrounds the first indicator ( 22 ) and is pivotally coupled to the housing ( 20 ) such that the second indicator ( 26 ) can rotate relative to the housing ( 20 ) about a second axis ( 32 ) orthogonal to the first axis ( 24 ) to maintain its angular position about the second axis ( 32 ) relative to the vertical axis irrespective of movement of the housing ( 20 ). The angular position of the housing ( 20 ) about the first and second axes ( 24,32 ) is indicated by the position of the first indicator ( 22 ) relative to the second indicator ( 26 ). In a second embodiment the housing ( 2 ) comprises a cavity filled with a fluid. An indicator ( 4 ) is supported within the fluid such that the indicator ( 4 ) can rotate relative to the housing ( 2 ) about a first axis to maintain its angular position about the first axis relative to a vertical axis irrespective of movement of the housing ( 2 ). The indicator ( 4 ) comprises a marking arranged to indicate the angular position of the indicator ( 4 ) relative to the housing ( 2 ) about the first axis. The housing ( 2 ) has at least one transparent portion for viewing the marking. A measuring element ( 8 ) is coupled to the housing ( 2 ) and arranged to slide relative to the housing ( 2 ) to be aligned with the indicator marking such that the angular position of the housing ( 2 ) about the first axis can be recorded.

Intravascular hinge stent

Номер: US20120065723A1

Автор: Joseph Michael Thielen, William Joseph Drasler

Принадлежит: Individual

A balloon or self expandable endoprosthesis formed of a single or multiple joined stent sections. Each section has a node and strut structure extending throughout in order to uncouple expansion forces of the stent to hold a blood vessel outward from crush forces that resist the formation of an oval shape during crush deformation. The hinge can bend in the direction of a uniformly curved surface of the stent but not in the radial direction. The strut can bend in the radial direction but not in the uniformly curved surface of the stent. The widths, lengths, and radial dimensions of the hinges and struts provide a balloon-expandable hinge stent that is non-crushable. For a self-expanding stent the hinge and strut dimensions provide expansion forces that are controlled independently from crush forces. Expansion properties are determined by the hinge dimensions and crush properties are determined independently by strut dimensions.

Selectively Expanding Spine Cage, Hydraulically Controllable In Three Dimensions for Vertebral Body Replacement

Номер: US20120116518A1

Автор: Rudy Pretti, Thomas Grotz

Принадлежит: Coalign Innovations Inc

A selectively expanding spine cage has a minimized diameter in its unexpanded state that is smaller than the diameter of the neuroforamen through which it passes in the distracted spine. The cage conformably engages between the endplates of vertebrae to effectively distract the anterior disc space, stabilize the motion segments, eliminate pathologic spine motion, or effect vertebral body replacement. Expanding selectively (anteriorly, along the vertical axis of the spine) rather than uniformly, the cage height increases and holds the vertebrae with fixation forces greater than adjacent bone and soft tissue failure forces in natural lordosis. Stability is thus achieved immediately, enabling patient function by eliminating painful motion. The cage shape intends to rest proximate to the anterior column cortices securing the desired spread and fixation, allowing for bone graft in, around, and through the implant for arthrodesis whereas for arthroplasty it fixes to endpoints but cushions the spine naturally.

Принадлежит: Individual

A stentless support structure capable of being at least partly assembled in situ. The support structure comprises a braided tube that is very flexible and, when elongated, becomes very long and very small in diameter, thereby being capable of placement within a small diameter catheter. The support structure is preferably constructed of one or more thin strands of a super-elastic or shape memory material such as Nitinol. When released from the catheter, the support structure folds itself into a longitudinally compact configuration. The support structure thus gains significant strength as the number of folds increase. This radial strength obviates the need for a support stent. The support structure may include attachment points for a prosthetic valve.

An invasive cardiac valve comprises a tubular stent ( 1 ) and a valve ( 2 ). One end of the tubular stent ( 1 ) is of a frusto-conical structure, the other end is wide open, and the diameter of the open end is greater than the diameter of the frusto-conical end. The valve ( 2 ) is attached to the frusto-conical end of the tubular stent ( 1 ); and a delivery and retrieval hole ( 4 ) of the cardiac valve is provided at the top of the open end of the tubular stent ( 1 ). Because the diameter of the open end is greater than the diameter of the frusto-conical end, the cardiac valve can be effectively fixed in a position of aortic annulus to prevent the cardiac valve displacement caused by the impact of the blood flow. Because the valve ( 2 ) is attached to the frusto-conical end of the tubular stent ( 1 ), the valve ( 2 ) can totally avoid the left and right coronary ostia and does not affect the haemodynamics of the coronary artery. Because a delivery and retrieval hole ( 4 ) of the cardiac valve is provided at the top of the open end of the tubular stent ( 1 ), the cardiac valve can be retrieved and reset at any time by handle control if it is found to be placed in an improper position during the release process.

An implant delivery catheter enables permanent modification of the implant length in the vicinity of the treatment site prior to radial expansion thereof. The implant is releasable carried between inner and outer tubular members of the delivery catheter which, upon repositioning relative to one another using an actuator mechanism, impart any of tensile, compressile or torquing forces to the implant causing permanent modification of the implant length. In one embodiment, the circumference of the implant is substantially similar both before and after modification of the implant length. In another embodiment, the implant includes a plurality of strut sections interconnected by bridges which are capable of the deformation along the longitudinal axis of the implant.

Devices and methods for the repair of the functioning of heart valves are provided. A device may comprise a first section having a generally spiral shape and a second section connected to the first section. A method involves positioning the device such that chords associated with the heart valve are positioned within the path of the generally spiral shape of the first section and positioning the second section on an opposite side of the heart valve. The first section may be turned in a manner such that the chords move closer to the center of the first section. The first section draws the chords closer together, thereby pulling the valve leaflets closer together in order to facilitate their coaptation and proper closing.
