    Abstract: A catheter with a mechanism for omni-directional deflection of a catheter shaft includes a shaft assembly and a controller. The shaft assembly includes a first tubular component that has a preformed curvilinear distal section, a second, substantially straight tubular component with a main axis and an outer shaft. The first and second components are configured for slidable movement therebetween while preserving common rotation so that when the second component is axially moved in a distal direction, the second component deflects the preformed curvilinear section towards the main axis while orientation of the outer shaft is preserved. The controller is configured to effect relative axial movement between the first and second components as well as to effect rotation of the first and second components (and thus also of the preformed curvilinear distal section) without any rotation of the shaft relative to the handle.

  • Patent number: 8894679
    Abstract: A surgical device mitigates over-puncture with a bias spring that biases a leading, cutting edge in the opposite direction of the anticipated over-puncture. An associated locking mechanism is configured to release the force of the bias spring in a direction counter to the direction of insertion when the tension force of tissue against the cutting edge is released. Thus, when an opening in the tissue forms, the tension is released and the cutting edge can move opposite to the direction of insertion of the surgical device at the same time that an applied force drives the instrument in the direction of insertion. In this manner, the spring and locking mechanism cooperate to move the cutting edge opposite to the direction of insertion as soon as an incision is made.

    Abstract: A catheter integral with a valved needle-free connector provides a safety catheter device configured to receive a blunt cannula and sharp needle forming an insertion mechanism. The sharp needle is mounted within a needle tube and a control handle is used to slide the sharp needle out of and into the protective needle tube. When the insertion mechanism is mounted to the connector and the control handle is used to slide the sharp needle out of the tube, a blunt cannula first moves into contact with and enters the bore of the valve mechanism of the connector opening it and protecting it from damage that may be caused by the sharp needle. The sharp needle is then extended through the connector and extends out the distal end of the catheter so that a venipuncture procedure may be performed to properly locate the catheter in the patient's circulatory system. Once located, the needle may be retracted into the insertion mechanism, the insertion mechanism disconnected from the connector, and discarded.

  • Patent number: 8343106
    Abstract: In various embodiments, a trocar cannula may be configured for insertion into an eye to facilitate insertion and removal of instruments during surgery. The cannula may be affixed to an overcap (to inhibit rotation of the overcap relative to the cannula) that includes a seal. In some embodiments, the seal may be overmolded into the overcap or may include a wafer that is fixed between the cannula and the overcap to inhibit rotation relative to the cannula and the overcap. In some embodiments, the cannula and overcap may snap together through a tab/slot interface in a permanent fashion such that the cannula and overcap may not be separated without damaging the cannula or overcap. In some embodiments, a vent cannula may be receivable in the slit of the seal for allowing fluids to vent from the eye through the cannula (which may include an indentation to frictionally engage the vent).

  • Patent number: 8333734
    Abstract: A peripheral nerve block needle for facilitating a peripheral nerve block procedure. A needle has several fenestrations along its length to allow an efflux of local anesthetic into a particular fascial compartment to treat a corresponding peripheral nerve despite only roughly approximating the location of such fascial compartment. A needle hub may be attached to the needle so that a backflow of fluid may be observed. A stylet is slidably disposed within the needle and needle hub such that selectively withdrawing the stylet from the apparatus enables a backflow of fluid into the needle hub, from which proper localization of the apparatus may be verified prior to administering local anesthetic. In this manner, local anesthetic may be effectively and efficiently administered to a peripheral nerve with reduced risk of injury to a patient.
