A phacoemulsification or aspiration tip is designed for use in cataract surgeries. The phacoemulsification tip (also referred to as a phaco tip) can reduce the duration and energy of cataract surgeries because the phaco tip is designed to reduce the likelihood that cataract fragments will become clogged inside the phaco tip. For example, the phaco tip has a lumen with variable sized diameters, which helps filter out larger cataract fragments that are more likely to clog the phaco tip. Further, the phaco tip can have a larger diameter at a bend to prevent blockages. The opening of the phaco tip can have a sharp edge to shear cataract fragments into smaller pieces that are less likely to clog the phaco tip. By preventing blockages using the phaco tip and reducing the duration of cataract surgeries, patients may recover faster from the cataract surgeries. |

Data link frame reordering
Datalink frames or networking packets contain protocol information in the header and optionally in the trailer of a frame or a packet. We are proposing a method in which part of or all of the protocol information corresponding to a frame or a packet is transmitted separately in another datalink frame. The “Separately Transmitted Protocol Information” is referred to as STPI. The STPI contains enough protocol information to identify the next hop node or port. STPI can be used avoid network congestion and improve link efficiency. Preferably, there will be one datalink frame or network packet corresponding to each STPI, containing the data and the rest of the protocol information and this frame/packet is referred to as DFoNP. The creation of STPI and DFoNP is done by the originator of the frame or packet such as an operating system. |
