Percutaneously deliverable heart valve

InactiveUS6875231B2Minimally invasivelyDecreasing circumferential lengthVenous valvesBlood vesselsProsthesisCardiac valve prosthesis
A percutaneously deliverable heart valve prosthesis and method of delivery, wherein the prosthesis is anchored to a valvular annulus of a patient and used to replace the patient's diseased valve. The prosthesis is supported by a rigid frame that is generally fixed, but capable of being modified between a first collapsed position and a second expanded position. In its first collapsed position, the prosthesis has sufficient flexibility and is of such a low profile that it allows for easy percutaneously delivery. Upon proper delivery, the prosthesis is anchored and modifiable to a generally permanent expanded position sufficiently rigid to resist the strong recoil force exerted by a distorted stenosed valve orifice displaced by the prosthesis.

Electrostrictive or piezoelectric actuator device with a stroke amplifying transmission mechanism

An actuator device (2) includes a piezoelectric or electro-strictive solid state actuator element (6) that is elongated upon application of an electric voltage thereto, and a transmission mechanism (8) that amplifies the stroke displacement of the actuator element. The transmission mechanism (8) includes a plurality of rigid frame members (12), including unitary frame members (12.1, 12.2) and divided frame members (12.3), and elastically flexible joints (10) that respectively interconnect the frame members. Each one of the divided frame members (12.3) is made up of a plurality of separate parallel link rods (16). Each flexible joint (10) is made up of a plurality of individual parallel hinge members (18) that respectively connect an end of each one of the link rods (16) to the adjacent unitary frame member (12.1, 12.2). By this division of the flexible joints and of the divided frame members into parallel sub-components, the cross-sectional thickness of each individual hinge member is reduced, and thereby the bending stiffness and the outer fiber strain of the material of the hinge members is significantly reduced while providing the same total tensile strength and tensile stiffness. The link rods of each divided frame member effectively form a parallelogram linkage for moving and guiding the output members (12.1) in a parallel manner.

Collaborative coexistence of co-located mobile wimax, wireless lan, and/or bluetooth radios

Collaborative coexistence of co-located mobile WiMAX, wireless LAN, and / or Bluetooth radios. Within a communication device that includes multi-protocol communication capability, the various radio modules included within such a communication device operate cooperatively such that collisions are avoided between those various radios. When a first of the radio modules operates as governed by a relatively rigid frame structure, a second of the radio modules capitalizes upon that predetermined nature (of the relatively rigid frame structure) to support communication during times in which that first radio module has a lower level of activity (e.g., turned off completely, within a power savings mode, in a sleep mode, etc.). The radio module operation is performed within a time-orthogonal manner, such that multiple radio modules are not attempting to transmit or receive simultaneously. Moreover, CTS2SELF operation can be employed alone or in conjunction with power savings operation of co-located radios within a communication device.
