摘要:
Vessel wound closure systems and method for sealing a puncture wound in a target vessel, such as those puncture wounds that occur from prior interventional procedures. A sealing member is deployed intravascularly into the target vessel, and an anchor member is deployed extravascularly of the target vessel. The sealing member and the anchor member are connected by a suture that may be drawn to tighten the sealing member and the anchor member relative to one another in order to effect the seal of the puncture wound. After tightening, the suture is secured to maintain the sealing member and the anchor member relative to one another in order to maintain the seal. Preferably, the anchor member, the suture and the sealing member are comprised of biocompatible, bioresorbable materials that are absorbed into the body after the sealing of the puncture wound has been achieved. The sealing member, suture and the anchor member are delivered by a delivery rod or other components over a guidewire or through an introducer already in place from the preceding interventional procedure.
摘要:
Vessel wound closure systems and method for sealing a puncture wound in a target vessel, such as those puncture wounds that occur from interventional procedures. The vessel wound closure system comprises at least a biocompatible, viscoelastic, self-sealing septum material injected onto the adventitia of the target vessel prior to performance of an interventional procedure. The prior injected septum material remains and seals the puncture wound of the target vessel even after various components associated with accessing the target vessel and the performance of the interventional procedure are removed from the target vessel and the puncture wound.
摘要:
A credential production system and methods for securely processing a credential substrate and tracking quantities of consumable material using a credentials production system and secured consumable supplies. The system includes a consumable supply and a memory that contains a state identifier that defines a state of the supply. A supply manager is configured to access the memory and set the state identifier to one of a production disabled state and a production enabled state. The system also includes a credential production device that is configured to receive the state of the supply. The credential production device is authorized to process a credential substrate using the consumable supply when the state identifier is set to the production enabled state, and the credential production device is prevented form processing the credential substrate using the supply when the state identifier is set to the production disabled state.
摘要:
A credential production system includes at least one credential production device, at least one computing device in communication with the at least one credential production device and a central administrator device configured to enable an authentication feature on the at least one credential production device. The at least one computing device is configured to access the at least one credential production device for providing processing instructions for processing a credential substrate. The at least one computing device is authenticated by the at least one credential production device prior to providing the processing instructions to the at least one credential production device.

Implantable devices formed of or coated with a material that includes an amorphous poly(D,L-lactide) formed of a starting material such as meso-D,L-lactide are provided. The implantable device can be used for the treatment, mitigation, prevention, or inhibition of a disorder such as atherosclerosis, thrombosis, restenosis, hemorrhage, vascular dissection or perforation, vascular aneurysm, vulnerable plaque, chronic total occlusion, patent foramen ovale, claudication, anastomotic proliferation for vein and artificial grafts, bile duct obstruction, ureter obstruction, tumor obstruction, or combinations thereof.
摘要:
A method and system for treating a bodily lumen with an implantable medical device, such as a stent, are disclosed. The device may be disposed within a bodily lumen and radially expanded by circumferentially deforming a tube-like section of the device. The deforming section may expand the lumen and the deformed section may support the lumen.
摘要:
A wireless telephone system provides telecommunications services for personal wireless telephone sets over an area which is divided into service cells. Each of the cells is defined by reception characteristics of a plurality of radio base stations within the cell. The telephone system includes a service controller and a port being wireline connected between each radio base station and the service controller. The service controller selects radio base stations for setting up radio links with wireless sets of calling or called persons. A base station which serves a wireless set and surrounding idle base stations monitor strengths of radio signals received from the wireless set and report running averages of the monitored signal strengths to the service controller. Movement of the wireless set from one cell to another cell during a call is detected as a drop in the running average reported by the serving base station. The service controller selects an idle base station to which the call is handed off based on the running averages reported by the idle base stations only idle base stations having a running average greater than the serving base station report their running average.
