Apparatus for applying surgical fastners to body tissue

An apparatus is disclosed for endoscopic application of surgical staples adapted to attach surgical mesh to body tissue in laparoscopic hernia surgery. The apparatus includes a frame, and a generally elongated endoscopic section connected to the frame and extending distally therefrom. A staple storage cartridge is removably supported on a pivotal support system at the distal end portion of the endoscopic section with each staple being configured and adapted to attach the mesh to the body tissue. An elongated pusher system formed of several assembled components and extending from the frame to the endoscopic section is provided for individually advancing at least one staple at a time distally for positioning adjacent the surgical mesh and the body tissue. The pusher system also includes a trigger system to actuate the pusher. The trigger system is provided with perceptible tactile sensing means to indicate when the legs of the staple being advanced are exposed so as to be visible to the user for positioning and orientation purposes. Anvil means provides for individually closing each staple to encompass at least a portion of the surgical mesh and to penetrate the body tissue in a manner to attach the portion of the mesh to the body tissue. Projecting distally of the cartridge support system is a pair of legs which are dimensioned and configured to engage the staple during closure to prevent unwanted roll or deformation outside of the plane of the staple.

Blockchain identity management system based on public identities ledger

The invention describes an identity management system (IDMS) based on the concept of peer-to-peer protocols and the public identities ledger. The system manages digital identities, which are digital objects that contain attributes used for the identification of persons and other entities in an IT system and for making identity claims. The identity objects are encoded and cryptographically encapsulated. Identity management protocols include the creation of identities, the validation of their binding to real-world entities, and their secure and reliable storage, protection, distribution, verification, updates, and use. The identities are included in a specially constructed global, distributed, append-only public identities ledger. They are forward- and backward-linked using the mechanism of digital signatures. The linking of objects and their chaining in the ledger is based on and reflect their mutual validation relationships. The identities of individual members are organized in the form of linked structures called the personal identities chains. Identities of groups of users that validated identities of other users in a group are organized in community identities chains. The ledger and its chains support accurate and reliable validation of identities by other members of the system and by application services providers without the assistance of third parties. The ledger designed in this invention may be either permissioned or unpermissioned. Permissioned ledgers have special entities, called BIX Security Policy Providers, which validate the binding of digital identities to real-world entities based on the rules of a given security policy. In unpermissioned ledgers, community members mutually validate their identities. The identity management system provides security, privacy, and anonymity for digital identities and satisfies the requirements for decentralized, anonymous identities management systems.

Substrate support system for reduced autodoping and backside deposition

A substrate support system comprises a relatively thin circular substrate holder having a plurality of passages extending between top and bottom surfaces thereof. The substrate holder includes a single substrate support ledge or a plurality of substrate support spacer vanes configured to support a peripheral portion of the substrate backside so that a thin gap is formed between the substrate and the substrate holder. The vanes can be angled to resist backside deposition of reactant gases as the substrate holder is rotated. A hollow support member provides support to an underside of the substrate holder. The hollow support member is configured to convey gas (e.g., inert gas or cleaning gas) upward into one or more of the passages of the substrate holder. The upwardly conveyed gas flows into the gap between the substrate and the substrate holder. Depending upon the embodiment of the invention, the gas in the gap can then flow either (1) outward and upward around the substrate edge or (2) downward through passages of the substrate holder, if any, that do not lead back into the hollow support member. The gas that flows outward and upward around the substrate edge inhibits backside deposition of reactant gases above the substrate. The gas that flows downward through the passages that do not lead back to the support member advantageously inhibits autodoping by sweeping out-diffused dopant atoms away from the substrate front side. In one embodiment, the support member comprises a hollow multi-armed support spider that conveys gas into selected ones of the passages. In another embodiment, the support member comprises a bowl- or cup-shaped structure that conveys gas upward into all of the passages. In yet another embodiment, the support member comprises a bowl- or cup-shaped structure that conveys gas upward into all but one or more of the passages.
