Minimally-invasive heart valve with cusp positioners

A prosthetic heart valve having an internal support frame with a continuous, undulating leaflet frame defined therein. The leaflet frame has three cusp regions positioned at an inflow end intermediate three commissure regions positioned at an outflow end thereof. The leaflet frame may be cloth covered and flexible leaflets attached thereto form occluding surfaces of the valve. The support frame further includes three cusp positioners rigidly fixed with respect to the leaflet frame and located at the outflow end of the support frame intermediate each pair of adjacent commissure regions. The valve is desirably compressible so as to be delivered in a minimally invasive manner through a catheter to the site of implantation. Upon expulsion from catheter, the valve expands into contact with the surrounding native valve annulus and is anchored in place without the use of sutures. In the aortic valve position, the cusp positioners angle outward into contact with the sinus cavities, and compress the native leaflets if they are not excised, or the aortic wall if they are. The support frame may be formed from a flat sheet of Nitinol that is bent into a three-dimensional configuration and heat set. A holder having spring-like arms connected to inflow projections of the valve may be used to deliver, reposition and re-collapse the valve, if necessary.

Dynamic stabilization system for the spine

A system for dynamic stabilization of the spine includes a bone engaging fastener configured to be anchored in a vertebra and a deflectable element mounted on the fastener. The deflectable element or bumper is configured and arranged to contact a portion of an adjacent vertebra, such as the facet, during extension of the spine, while offering no resistance during flexion. In certain embodiments, a cable may be fastened to the bone engaging fastener and arranged to contact a portion of the adjacent vertebra, such as the spinous process, during flexion of the spine. In one surgical technique of the invention, a contralateral approach is used to introduce the bone engaging fastener through the deflectable element and into the vertebra.

Anchoring element for securing a rod of a device for adjusting a human or animal vertrebal column on a vertreba

The invention relates to an anchoring element for securing a rod of a device for adjusting a human or animal vertebral column on a vertebra, comprising a retaining means (10) for receiving the rod, a safety element (26) placed on the retaining means and working against the rod, a securing element (14) which can be placed on the body of the vertebra, and a clamping device (12) which is arranged between the retaining means (10) and the securing element (14), comprising a ring-shaped mount (32), a partially conical-segment shaped bearing (28) and an intermediate element (30) which is embedded in the mount (32) and which engages the bearing, whereby the mounting (32) is moveable in a removed state in relation to the bearing (28), whereas the mount (32) is maintained in a clamped state on the bearing (28) by means of the intermediate element (30). The mount (32) is rigidly connected to the retaining means (10) and the bearing (28) is rigidly connected to the securing element (14). In order to enable said type of anchoring element, despite the fact that it is displaceably retained, to transmit relatively large amounts of force from the rod to the body of the vertebra without causing slipping, the bearing (28) comprises flat guiding surfaces (38, 40) which are formed laterally on two opposite sides (34, 36), and the intermediate element (30) is provided with corresponding counter surfaces (50, 52).

Treatment of epilepsy by brain stimulation

Introducing one or more stimulating drugs to the brain and / or applying electrical stimulation to the brain is used to treat epilepsy. At least one implantable system control unit (SCU) produces electrical pulses delivered via electrodes implanted in the brain and / or drug infusion pulses delivered via a catheter implanted in the brain. The stimulation is delivered to targeted brain structures to adjust the activity of those structures. The small size of the SCUs of the invention allow SCU implantation directly and entirely within the skull and / or brain. Simplicity of the preferred systems and methods and compactness of the preferred system are enabled by the modest control parameter set of these SCU, which do not require or include a sensing feature.
