A microcatheter system that allows for vascular infusion into retinal veins for extended periods of time. The microcatheter system includes a flexible cannula that is inserted into the retinal vein lumen and that remains stably within the retinal vein lumen without being held by a robot, micromanipulator or similar holding devices. The microcatheter system is particularly suitable for the treatment of retinal venous occlusive disease.

A voice command and control medical care system is provided which comprises a processor having a continuous speech recognition capability. The processor is programmed to process a user's conversational speech to identify valid commands therein and to generate control signals for operating medical equipment such as surgical tools in accordance with the commands. The processor is programmed to generate audio messages reporting status information when requested, and to generate confirmation messages and await acknowledgement before executing a command. The system is configurable to interface with and control via voice activation essentially and piece of medical equipment having instruments and control switches that can be controlled via electrical or electromagnetic signals.

A surgical instrument includes a handle having a pair of actuating wings and a removable instrument tip. The instrument tip is constructed to perform a surgical operation. The handle includes an axially movable slider actuated by the actuating wings which operate the instrument tip. A shaft extends through the handle and is coupled to the instrument tip so that rotation of the shaft rotates the tip without interfering with the axial movement of the slider. The gripping surface of the actuating wings have a rounded surface to allow limited rotational movement of the instrument in the user's hand. The gripping surfaces are inclined toward the instrument tip to resist the handle slipping from the user's hand during use in the near vertical orientation.
