摘要： Systems, methods and devices are provided for treating heart failure patients suffering from various levels of heart dilation. Heart dilation treated by reshaping the heart anatomy with the use of magnetic forces. Such reshaping changes the geometry of portions of the heart, particularly the right or left ventricles, to increase contractibility of the ventricles thereby increasing the stroke volume which in turn increases the cardiac output of the heart. The magnetic forces are applied with the use of one or more magnetic elements which are implanted within the heart tissue or attached externally and/or internally to a surface of the heart. The various charges of the magnetic forces interact causing the associated heart tissue areas to readjust position, such as to decrease the width of the ventricles. Such repositioning is maintained over time by the force of the magnetic elements, allowing the damaging effects of heart dilation to slow in progression or reverse.

摘要： An annuloplasty ring having a three-dimensional discontinuous form generally arranged about an axis with two free ends that are axially offset. The ring is particularly suited for repair of the tricuspid valve, and more closely conforms to the annulus shape. The ring is more flexible in bending about radially extending axes than about the central axis. The ring may have an inner structural support covered by a pliable sleeve and/or a fabric tube. The structural support may have a varying cross-section, such as a C-shaped cross-section in a mid-section between two free ends and a rectangular cross-section at the free ends. A deliver template having a mounting ring with about the same shape as the ring facilitates implant, and may be releasably attached to a delivery handle. The deliver template may include a plurality of cutting guides for releasably attaching the annuloplasty ring thereto while presenting maximum outer surface area of the ring. The template may have an outwardly-facing groove to receive and retain the ring.

摘要： An annuloplasty repair segment and template for heart valve annulus repair. The elongate flexible template may form a distal part of a holder that also has a proximal handle. Alternatively, the template may be releasably attached to a mandrel that slides within a delivery sheath, the template being released from the end of the sheath to enable manipulation by a surgeon. A tether connecting the template and mandrel may also be provided. The template may be elastic, temperature responsive, or multiple linked segments. The template may be aligned with the handle and form a two- or three-dimensional curve out of alignment with the handle such that the annuloplasty repair segment attached thereto conforms to the curve. The template may be actively or passively converted between its straight and curved positions. The combined holder and ring is especially suited for minimally-invasive surgeries in which the combination is delivered to an implantation site through a small access incision with or without a cannula, or through a catheter passed though the patient's vasculature.

摘要： A sizer measures a valve annulus to determine a size of an artificial heart valve to be sewn in the valve annulus during heart-valve replacement surgery. The sizer includes a support member and a resilient member. The support member has a size corresponding to the size of one of a plurality of artificial heart valves. The resilient member is disposed about the support member and has a resiliency substantially equal to the resiliency of a sewing ring of the artificial heart valve. Accordingly, when a surgeon inserts the sizer into a valve annulus, the resilient member conforms to the shape of the valve annulus much like the sewing ring will conform when positioned in the annulus and sewn in place. The surgeon is therefore able to determine more accurately the size of the annulus and, thereafter, to select a properly sized artificial valve.

摘要： A method of surgery including bending a multi-purpose surgical implement handle that has proximal and distal ends. A gripping section is located toward the proximal end, and an attachment section is located toward the distal end. An adjusting section is interposed between the gripping section and the attachment section. The adjusting section may be bent by a human user at virtually any discrete location along the section. The adjusting section may include an increased-adjustability portion which is easier to bend than other portions of the adjusting section. The method includes attaching a surgical implement to the attaching section of the handle, and bending the adjusting section at least once prior to inserting the implement through a surgical opening to a surgical field. The method further may include bending the adjusting section more than once to form multiple bends therein.

摘要： Surgical apparatus and associated methods of use are provided for retracting tissue around an incision. The apparatus includes a member having an inner peripheral surface and an outer peripheral surface. An adjustable aperture is definable within the inner peripheral surface as the member is adjusted between a compressed condition in which the aperture is substantially closed and an expanded condition in which the aperture is substantially open. The apparatus is positioned within a surgical incision in the compressed condition, and is adjusted to the expanded condition in situ to define an opening within the incision through the aperture whereby a surgical field may be viewed and/or accessed.

摘要： Systems and devices for endovascular treatment of intracranial aneurysms are described. Various configurations of coiled implants may be used as stenting devices or aneurysm coils. The implants include one or more filaments wound about a longitudinal axis to form a generally tubular shape. Lateral flexibility of the implants may be manipulated by, for example, adjusting a pitch between adjacent filaments, using different materials for the filaments, employing different filament cross-sectional shapes, grouping filaments into pluralities of varying flexibilities, and nesting inner coils within outer coils.

摘要： Provided is a vascular stent used in percutaneous coronary intervention (PCI) which is specially designed for multiple drug loading and improved drug elution, including: a plurality of ring structures extending in the longitudinal direction of the vascular stent, including a plurality of struts disposed in a zigzag formation and connected to each other to form a cylindrical loop; and a plurality of link structures disposed between the ring structures and connecting the ring structures in the longitudinal direction of the vascular stent, wherein each of the struts in a ring structure is connected to adjacent struts in the same ring structure through one of a plurality of linking ends, a slot loaded with drugs is formed in the strut in the longitudinal direction of the strut, and a multi-layer structure comprising a plurality of layers of drugs is loaded in the slot. The vascular stent effectively inhibits restenosis by loading a large amount of a drug or various types of drugs in multiple layers in slots of struts in the vascular stent and controlling elution of the drugs, and can be easily installed in a serpentine coronary artery with excellent flexibility. In addition, the link structure of the vascular stent is disposed in a symmetric formation, and thus, side branch accessibility is excellent and an additional coronary intervention can be performed easily in a branched artery.
