  • Patent number: 9610425
    Abstract: Methods of providing image-guided transendocardial injection of a therapeutic agent into a left ventricular wall of a heart. Some methods enable injections into heart tissue under visualization. The methods may include providing an endoventricular injection catheter having integrated echocardiographic capability. The endoventricular injection catheter may have an imaging core and an injection system carried on the elongated body with the imaging core. The method may include positioning the endoventricular injection catheter into the left ventricle of the heart, which inserts the imaging core into the heart. The method may also include transmitting ultrasonic energy via the imaging core, receiving reflected ultrasonic energy at the distal end, visualizing the left ventricular wall of the heart using the imaging core, identifying infarct regions of the left ventricle, and injecting a therapeutic agent into the visualized infarcted regions of the left ventricle using the injection system.

  • Publication number: 20150141776
    Abstract: A subcutaneous access device has a skin attachment plate coated with an adhesive layer. The skin attachment plate is moveably linked by a retraction mechanism to a needle support with fixedly positioned needles. In the ready-to-use position the skin attachment plate is spaced away from the needle support and covers the fixedly positioned needles. Subcutaneous insertion of the needles is effected by attachment of the skin attachment plate with the adhesive layer to the skin and releasing the retraction mechanism, thus triggering the pulling of the attached skin with high velocity against the tip of the needles.

    Abstract: According to one embodiment, a cannula assembly may include a cannula module and an inserter module. In the pre-operational state the cannula is retracted with respect to the skin-contacting surface. In operational state the cannula projects beyond the skin-contacting surface. The inserter module may include an energy store and an activation mechanism. When the energy store is at least partially discharged, the stored potential energy is transformed to kinetic energy that moves the cannula from the pre-operational state to the operational state. The activation mechanism is triggerable from outside the cannula assembly with a trigger device. The activation mechanism prevents the energy store from being discharged before it is triggered by the trigger device, and enables the energy store to be discharge after it is triggered by the trigger device to force the cannula from the pre-operational state into the operational state.

  • Patent number: 8475410
    Abstract: According to one embodiment, a cannula assembly may include a cannula module and an inserter module. In the pre-operational state the cannula is retracted with respect to the skin-contacting surface. In operational state the cannula projects beyond the skin-contacting surface. The inserter module may include an energy store and an activation mechanism. When the energy store is at least partially discharged, the stored potential energy is transformed to kinetic energy that moves the cannula from the pre-operational state to the operational state. The activation mechanism is triggerable from outside the cannula assembly with a trigger device. The activation mechanism prevents the energy store from being discharged before it is triggered by the trigger device, and enables the energy store to be discharge after it is triggered by the trigger device to force the cannula from the pre-operational state into the operational state.

  • Patent number: 8313463
    Abstract: An injection device 110 is described having a housing 112 that receives a syringe 114. The syringe 114 is biased by a return spring 126 from an extended position in which the needle 118 extends from the housing 112 through an exit aperture 128 to a retracted position in which it does not. A drive spring 130 acts via a drive to advance the syringe 114 from its retracted position to its extended position and discharge its contents through the needle 118 and a return spring 126, brought into play when the drive has reached a nominal return position, restores the syringe 114 to its retracted position. A releasable locking mechanism retains the syringe 114 in its retracted position. A sleeve 119 projects from the exit aperture 128 and can be depressed to release the locking mechanism.
