A novel system for performing a heart valve annuloplasty. The system involves the use of a plication band. In one embodiment, the annulus of the valve is reduced by constriction of the plication band itself. More particularly, each plication band enters the tissue at two or more points which are spaced from one other by a distance which is dictated by the geometry of the plication band. Subsequent constriction of the plication band causes these points to move toward each other, thereby constricting the tissue trapped between these points and thus reducing the overall circumference of the valve annulus. In a second embodiment, the annulus of the valve is reduced by linking multiple plication bands to one other, using a linkage construct, and then using a shortening of the length of the linkage construct between each plication band so as to gather the tissue between each plication band, whereby to reduce the overall circumference of the valve annulus.

Registration of non-configured network devices in a distributed network is facilitated by a method of distributing cryptographic keys. A non-configured first device seeking to communicate securely with a second device acquires knowledge of a trusted registration service. The first device registers with the registration service and obtains a longer-lived symmetric key. Using the longer-lived key, the first device authenticates itself to a key management service, and receives a shorter-lived symmetric key encapsulated in a ticket that includes policy information. A second device carries out the same preparatory process. Using its ticket containing the shorter-lived key, the first device requests the second device to obtain a session key on behalf of both. The second device presents its own ticket and that of the first device to the key management service to authenticate the shorter-lived key, and then obtains a session key for use in communications among the first and second devices. The first device and second device then communicate by encrypting communications with the session key, and without further contact with the key management or registration services or any other online authoritative server or key database. Thus newly deployed network devices may be positively identified, registered in the network, and subjected to key schedule or other key management policies.

A surgically implanted spinal stabilization system uses posterior anchor hooks attached to vertebrae to retain elastic bands to retain flexibility and mobility while maintaining alignment and preventing excessive motion and deformity.

Multi-level fixation can be achieved using the spinal stabilization system with longer elastic bands. A method of applying the spinal stabilization system using an elastic band application tool facilitates simple, rapid application of the system to a patient.

A system for creating lesions and assessing their completeness or transmurality. Assessment of transmurality of a lesion is accomplished by monitoring the impedance of the tissue to be ablated. Rather than attempting to detect a desired drop or a desired increase impedance, completeness of a lesion is detected in response to the measured impedance remaining at a stable level for a desired period of time, referred to as an impedance plateau. The mechanism for determining transmurality of lesions adjacent individual electrodes or pairs may be used to deactivate individual electrodes or electrode pairs, when the lesions in tissue adjacent these individual electrodes or electrode pairs are complete, to create an essentially uniform lesion along the line of electrodes or electrode pairs, regardless of differences in tissue thickness adjacent the individual electrodes or electrode pairs.

The disclosure describes a peer-to-peer consensus system and method for achieving consensus in tracking transferrable digital objects. The system achieves consensus on a shared ledger between a plurality of peers and prevents double spending in light of network latency, data corruption and intentional manipulation of the system.

A method and apparatus for separating a mixture of particles of various sizes in a capillary tube into groups by size using multiple forces of controlled amplitude. Ultrasonic radiation at a first selected frequency is applied to set up a standing pressure wave in the capillary tube, resulting in a first aggregating force which causes particles of all sizes to aggregate at positions within the capillary tube which correspond to nodes or anti-nodes of the standing wave. Transverse vibrations are also applied to the capillary tube. The frequency of the ultrasonic radiation is adjusted to reduce the magnitude of the first aggregating force. Inertial forces resulting from the transverse vibrations then cause the particles to separate by size.

This disclosure provides an improved system for culturing human pluripotent stem cells. Traditionally, pluripotent stem cells are cultured on a layer of feeder cells (such as mouse embryonic fibroblasts) to prevent them from differentiating. In the system described here, the role of feeder cells is replaced by components added to the culture environment that support rapid proliferation without differentiation. Effective features are a suitable support structure for the cells, and an effective medium that can be added fresh to the culture without being preconditioned by another cell type. Culturing human embryonic stem cells in fresh medium according to this invention causes the cells to expand surprisingly rapidly, while retaining the ability to differentiate into cells representing all three embryonic germ layers. This new culture system allows for bulk proliferation of pPS cells for commercial production of important products for use in drug screening and human therapy.
