  • Patent number: 11844510
    Abstract: A method of anchoring soft tissue to a suitable bone site, using a soft suture anchor, includes steps of disposing the soft suture anchor on a shaft of an inserter, and securing a proximal end of a tensioning suture limb, extending proximally from the soft suture anchor, to structure in a handle of the inserter, so that it is maintained in place at a first level of holding tension (Thold). The inserter shaft is inserted into a hone hole at a desired procedural site, so that the soft suture anchor is positioned at a location where it is to be anchored. A further step involves actuating a control mechanism in the inserter handle to move the structure proximally to apply a second level of deployment tension (Tload) to the tensioning suture limb.

  • Patent number: 11096681
    Abstract: An all-suture suture anchor system includes an all-suture anchor, an inserter, and a specially designed drill. The drill is used to enlarge the hole and create a pocket under the bone surface from the pre-drilled hole. The created pocket is intended to accommodate the expansion of the anchor when deployed into the bone, generating a true mechanical interference under the bone surface. The anchor is loaded on the inserter and placed at full length vertically inside the drilled hole. While holding the inserter on top of the drilled hole, so that a feature on the inserter keeps the anchor to a desired depth below the bone surface, tension is applied to the suture limb that is connected to the bottom end of the anchor. This tensioning step causes the length of the anchor to contract vertically and the anchor is simultaneously expanded circumferentially to fill the pocket previously created by the drill.

  • Publication number: 20170156718
    Abstract: A method of anchoring soft tissue to a suitable bone site, using a soft suture anchor, includes steps of disposing the soft suture anchor on a shaft of an inserter, and securing a proximal end of a tensioning suture limb, extending proximally from the soft suture anchor, to structure in a handle of the inserter, so that it is maintained in place at a first level of holding tension (Thold). The inserter shaft is inserted into a bone hole at a desired procedural site, so that the soft suture anchor is positioned at a location where it is to be anchored.

  • Patent number: 6515839
    Abstract: An ESD protection system that makes use of several different types of over-voltage protection devices provides ESD conduction paths between different power lines. For example, the system may employ shunt diodes between the ground lines of the different power supplies and between IC pads and power supply lines; SCR protection between IC pads and ground; and thick field device protection between different power supply VDD lines. In this way, a conduction path for an ESD event between two circuit elements may be implemented using the device whose switching characteristics are best suited to that application.

  • Patent number: 6002567
    Abstract: The present invention provides for ESD protection while allowing the use of an input signal that is higher than V.sub.DD. The present invention preferably includes a protection device and a delay circuit coupled to an input pad and to a ground reference. The protection device is a preferred silicon controlled rectifier, and the delay circuit is preferably a low pass filter RC circuit that includes a resistor and a capacitor. A node associated with the delay circuit is coupled to circuitry of an integrated circuit. The circuitry has associated therewith at least one gate oxide breakdown voltage. A gate oxide breakdown voltage is prevented from being applied to the circuitry of the integrated circuit. When an ESD voltage is applied to the input pad, the voltage at that pad ramps or increases quickly. The delay circuit prevents the node from ramping as quickly by delaying the ramping or increasing of the node voltage. This delay provides time for the protection device to turn on and sink the ESD current.

  • Patent number: 5999029
    Abstract: A meta-hardened circuit that reduces the effects of metastability preferably includes a pulse generator coupled to receive a first clock signal and generate in response thereto a second clock signal and an enable signal. A buffer, preferably tri-state, is coupled to receive a first data signal and the enable signal and generate in response thereto a second data signal. A bi-stable device, such as a flip-flop, is coupled to receive the second clock signal and the second data signal. The pulse generator preferably includes a combining device and a delay device. The buffer preferably includes at least one tri-state inverter and a keeper circuit. A method to reduce the metastability effects preferably includes the step of generating a delay between a second data input signal and a second clock signal that is greater than a delay between a first data input signal and a first clock signal. The step of generating preferably occurs in one clock cycle.

  • Patent number: 5894153
    Abstract: An integrated circuit formed on a semiconductor substrate has a contact pad for communicating signals between an external device and an internal signal line. The pad is protected by an SCR that conducts electrostatic discharge pulses from the pad directly to a current sink. The SCR includes a subregion underneath a field oxide that has a field inplant that increases the dopant concentration. The field implant lowers the SCR trigger voltage, so that SCR triggers before an ESD pulse can cause latch-up or damage in other devices in the integrated circuit.

  • Patent number: 5528447
    Abstract: In an electronic IC package, an I/O PAD circuit design which protects 3 Volt optimized I/O functional circuits from damage due to the application of external 5 Volt signals to the I/O PAD both while the functional circuit design is powered on and powered off. When the I/O circuits associated with the I/O PAD are powered on, the present invention protects the I/O circuits by applying well known designs. However, when the I/O circuits associated with the I/O PAD are powered off, the present invention draws power from the external 5 Volt signal to activate additional transistors to protect the powered off I/O circuits.
