Abstract: Devices used to pressurize, depressurize, or otherwise displace fluid are disclosed. The devices may be configured to displace fluid in order to inflate or deflate a medical device, such as a balloon. The devices include a trigger configured to convert the devices from a pressurization state to a priming state. The devices further include a locking or toggle member configured to toggle and/or maintain the devices in a priming state.

Abstract: Devices used to pressurize, depressurize, or otherwise displace fluid are disclosed. The devices may be configured as a syringe. The syringe may be configured to generate high-pressure within the syringe to inflate or deflate a medical device, such as a balloon, or to inject a substance, such as bone cement, into a bone, such as a vertebra. The syringe may include a pressure reduction mechanism used to depressurize the syringe.

Abstract: The disclosure includes an arrangement for a handle for a catheter system that includes a first member and a second member. The handle can include a screw member positioned within the handle and configured for rotation about an axis. The screw member can include an internal thread. A carriage can be positioned within the screw member. The carriage can engage the internal thread and can be coupled to the first member. An alignment member can extend within the screw member to limit rotation of the carriage about the axis as the screw member is rotated. Rotation of the screw member in a first direction about the axis can cause the carriage to move in a first longitudinal direction within the screw member causing the first member to move in the first longitudinal direction relative to the handle.

Abstract: An instrument is disclosed for use with implants, particularly for use in implanting retinal implants into the sub-retinal space of an eye. The instrument includes a handpiece and an inserter attachment. The handpiece includes a first sliding member movably disposed within a longitudinal channel of the handpiece and comprising finger portions adapted to couple and retain the inserter attachment to the handpiece. A nose member of the handpiece includes at least two recesses for mating with a locating pin in the inserter attachment for maintaining alignment of the inserter attachment. The inserter attachment includes a pusher cap that is biased to retain a pusher in a retracted position. Also, an inserter tip of the inserter attachment includes a cover that defines a space for and helps retain the implant within the inserter attachment.
