37179 results about "Biological activation" patented technology

In biochemistry, activation, specifically called bioactivation, is where enzymes or other biologically active molecules acquire the ability to perform their biological function, such as inactive proenzymes being converted into active enzymes that are able to catalyze their substrates into products.

Tissue pad for use with an ultrasonic surgical instrument

InactiveUS20060079874A1Effectively smooths out abusive tissue forceSurgical instrument detailsSurgical forcepsBiological activationSurgical department
An ultrasonic clamp coagulator assembly that is configured to permit selective cutting, coagulation and clamping of tissue during surgical procedures. An elongated portion of the instrument can be configured for endoscopic applications and has an outside diameter of less than 6 mm. The construction includes a clamping mechanism, including a clamp arm pivotally mounted at the distal portion of the instrument, which is specifically configured to create a desired level of tissue clamping forces, exceeding 4 pounds when the trigger is fully closed. The clamping mechanism includes a two-piece pad design and pad material that enables the higher tissue clamping forces and a force-limiting mechanism that effectively smooths out abusive tissue forces. The assembly also features hand activation configured to provide an ergonomical grip and operation for the surgeon. Hand switches are placed in the range of the natural swing of the surgeon's thumb, whether gripping the surgical instrument right-handed or left handed.

Centrifugal communication and collaboration method

A method of facilitating communications and collaboration of a group of plural remote participants comprises steps of receiving information over an information communications network from a first group participant; pushing, over the network to at least one other group participant, an access via an access channel; and allowing the other group participant to access at least some of the received information via said access channel in response to selective activation of the access channel by the other group participant.

Operation of a computer with touch screen interface

A touch screen computer executes an application. A method of operating the touch screen computer in response to a user is provided. A virtual input device is provided on the touch screen. The virtual input device comprises a plurality of virtual keys. It is detected that a user has touched the touch screen to nominally activate at least one virtual key, and a behavior of the user with respect to touch is determined. The determined behavior is processed and a predetermined characteristic is associated with the nominally-activated at least one virtual key. A reaction to the nominal activation is determined based at least in part on a result of processing the determined behavior.

Circular stapler buttress combination

A combination medical device comprising a circular stapler instrument (4) and one or more portions of preformed buttress material (16) adapted to be stably positioned upon the staple cartridge (12) and / or anvil (14) components of the stapler (4) prior or at the time of use. Positioned buttress material(s) (16) are delivered to a tissue site where the circular stapler (4) is actuated to connect previously severed tissue portions. An embodiment of the invention allows tissue portions to be joined without the use of sutures. The buttress material (16) is made up of two regions, one of which serves primarily to secure the buttress material (16) to the stapler (4) prior to acuation, and one of which serves primarily to form the improved seal. The former region is severed and discarded upon activation of the circular stapler (4) to form anastomoses, while the remaining material secures and seals the newly connected tissue. Methods of use and preparation of the buttress material (16) are also described.

Expandable intervertebral spacer method and apparatus

InactiveUS20060129244A1Restore disc heightBone implantSurgeryBiological activationIntervertebral disk
An expandable interbody spacer (IBS) device designed to restore the disc height between vertebral bodies. The expandable interbody spacer device has an integral, moveable expansion member or spreader, provided between two plates. The plates are connected by one or more connecting members that retain the plates in a position proximate to one another while allowing the plates to move from a first unexpanded position to a second expanded position upon activation of the expansion member. According to aspects of the invention, the interbody spacer device can be implanted in an unexpanded or collapsed configuration, and then expanded to full height by engaging the expansion member. In other embodiments, the interbody spacer device may take various forms, for example, it may be cashew, rectangular or annular.

Systems and methods for communicating token attributes associated with a token vault

Systems and methods for interoperable network token processing are provided. A network token system provides a platform that can be leveraged by external entities (e.g., third party wallets, e-commerce merchants, payment enablers / payment service providers, etc.) or internal payment processing network systems that have the need to use the tokens to facilitate payment transactions. A token registry vault can provide interfaces for various token requestors (e.g., mobile device, issuers, merchants, mobile wallet providers, etc.), merchants, acquirers, issuers, and payment processing network systems to request generation, use and management of tokens. The network token system further provides services such as card registration, token generation, token issuance, token authentication and activation, token exchange, and token life-cycle management.

Closed system artificial intervertebral disc

An artificial intervertebral disc and disc nucleus are described herein having chambers and dampening members. The dampening members may be within or outside of the main body of the device. The chambers may be filled with a suitable liquid, gas, or both, and separated by valves to regulate flow of fluid between chambers, within a dampening member, between the main body and dampening member, or all of the above. Chambers may be filled with responsive hydrogels, EPAM, or other suitable materials, and the device may have activation plates or members, a strain gauge, a pressure sensor, or other means for detecting changes in the materials and / or triggering desired changes in the materials in order to mimic the behavior of a healthy native disc or disc nucleus. A control system may be in communication with the device for receiving feedback and delivering stimuli to initiate desired changes in the fluids or other materials. Membranes may be of variable permeability and may be metallized to ensure as low permeability as possible. Dampening members may be filled during manufacture with carbon dioxide or other suitable gas which may be in a supercritical state and allowed to return to ambient temperature and gaseous state or by other means. Methods of manufacture, delivery of the artificial disc and related structures, and methods of treatment are also described.

Software control plane for switches and routers

A Provider Network Controller (PNC) addresses the challenges in building services across Next Generation Network (NGN) architectures and creates an abstraction layer as a bridge, or glue, between the network transport and applications running over it. The PNC is a multi-layer, multi-vendor dynamic control plane that implements service activation and Layer 0-2 management tools for multiple transport technologies including Carrier Ethernet, Provider Backbone Transport (PBT), Multi-protocol Label Switching (MPLS), Transport MPLS (T-MPLS), optical and integrated networking platforms. Decoupling transport controls and services from the network equipment simplifies service creation and provides options for carriers to choose best-in-class equipment that leverages the PNC to enable rapid creation and management of transports and services. The PNC provides Service-Oriented Architecture (SOA) interfaces to abstract transport objects expressly designed to support both wholesale and retail services, and supports service offerings with varied bandwidth and Quality of Service (QoS) requirements, thus achieving enterprise Ethernet economics.
