Methods of using the device to treat a cerebral aneurysm are also described. Methods of forming a tubular braid are also described. Methods of forming a tubular braid with variable braid densities are described. Methods of forming a tubular braid using a castellated mandrel are also described.

  • Patent number: 9955976
    Abstract: Devices and methods for treatment of a patient's vasculature are described. The devices include implants made of woven braided mesh having a variable mesh density, i.e., the average size of pores in one region are a different than the average size of pores in another region. Additionally, there is a transition zone between the two regions. The implants have a low profile radially constrained state and an expanded state that is axially shortened. Methods of using the device to treat a cerebral aneurysm are also described. Methods of forming a tubular braid are also described. Methods of forming a tubular braid with variable braid densities are described. Methods of forming a tubular braid using a castellated mandrel are also described.

  • Publication number: 20170235886
    Abstract: Mechanisms are provided for evaluating a patient registry and performing actions based on results of the evaluation. The mechanisms receive a multi-level cascading set of rule structures for evaluating attributes of the patient registry. The mechanisms apply the multi-level cascading set of rule structures to the patient registry. In addition, the mechanisms determine, for each rule structure in the multi-level cascading set of rule structures, whether a criteria of the rule structure is met by the attributes of the patient registry. Moreover, the mechanisms perform, for each rule structure whose criteria is met by the attributes of the patient registry, a corresponding patient care action triggered by the criteria of the rule structure being met.

  • Publication number: 20170220757
    Abstract: Mechanisms are provided for communicating with a patient. The mechanisms generate a patient registry comprising a plurality of patient registry records, each patient registry record being associated with a corresponding patient and comprising personal and medical information about the corresponding patient. The mechanisms collect, for each patient registry record, first data regarding treatment of the corresponding patient and second data regarding communications made with the corresponding patient. The mechanisms determine, based on analysis of the first data and second data associated with each of the patient registry records, a mode of communication that is most likely to result in a successful treatment of patients. The mechanisms initiate a communication with a patient of interest using the determined mode of communication based on the results of the determination.

  • Publication number: 20170213005
    Abstract: Mechanisms are provided for caching patient information in a variable list and using the variable list to evaluate patient rules. The mechanisms generate a patient registry comprising a plurality of patient registry records, each patient registry record being associated with a corresponding patient and comprising personal and medical information about the corresponding patient. The mechanisms compile at least one variable list for an input variable of one or more clinical rules. The variable list comprises a plurality of instances of personal and medical information from the plurality of sources that are associated with the variable. The mechanisms also process at least one clinical rule in the one or more clinical rules that references the variable as a criteria for evaluating the at least one clinical rule, based on the variable list associated with the variable to determine if the criteria is satisfied by one or more instances.

  • Patent number: 9714731
    Abstract: A system for joining pipe segments, the system including a first pipe connector connected to a first pipe segment, and a second pipe connector threadingly connectable to the first pipe connector, and connected to a second pipe segment. The system further includes a recess in the outer surface of the first pipe connector, and an elongated key having first and second lengthwise surfaces. One of the lengthwise surfaces has protrusions that embed into a transverse surface of the second pipe connector when the key is mounted into the recess.
