  • Publication number: 20080234659
    Abstract: According to an aspect of the present invention, urological medical devices are provided, which contain one or more urologically beneficial agents selected from alpha-adrenergic blockers, calcium channel blockers, and combinations thereof, among others. The urological devices are adapted for implantation or insertion into a subject's urinary tract, whereupon at least a portion of the urologically beneficial agent is released. Such agents are urologically beneficial, for example, in that they may relieve pain and/or discomfort associated with the medical device and/or act as stone expulsion agents (i.e., they facilitate stone passage), among other benefits. According to an aspect of the present invention, a method of treating kidney stones is provided which comprises: (a) diagnosing the presence of kidney stones within a subject and (b) implanting or inserting a urological medical device into the subject which contains at least one urologically beneficial agent.

  • Publication number: 20080101258
    Abstract: A method for easily configuring a network, network connections, and electronic devices in the network is disclosed. A user interface conveniently displays the current network configuration in a topological diagram. Each device in the network is displayed as an icon. Connections between the devices are also shown in the user interface. If a user decides to reconfigure the network, the user simply clicks on the appropriate icon and drags the device to the desired location. The new connection is automatically established and the topological diagram of the network in the user interface is automatically updated to display the new network configuration. If the new configuration is not compatible, the user interface displays a warning message explaining the conflict to the user. The user interface also comprises a relation list showing connection relationship between devices, a connection status area showing connection status, and an unused device area.

  • Publication number: 20080103479
    Abstract: Methods for placing a medical agent at a location within a patient's vessel. In an illustrative embodiment, an embolic coil is placed at a location with an aneurysm. The methods include the steps of providing a catheter having a proximal end and a distal end, a balloon adjacent to the distal end, an inflation port at the proximal end communicating via an inflation lumen with the balloon, a delivery port at the proximal end communicating with a delivery lumen, a guidewire opening at the distal end communicating with the delivery lumen, and a side opening near the distal end and spaced from the guidewire opening and also communicating with the delivery lumen. The catheter is pre-loaded with a guidewire extending from the delivery port through the delivery lumen and distal of the guidewire opening. Thereafter, the catheter is introduced into the vessel of a patient to generally align the side opening with the aneurysm. The balloon is inflated to stabilize the position of a distal portion of the catheter.

  • Publication number: 20080101330
    Abstract: A method for easily connecting electronic devices, wireless access points, and access point clients and for efficiently configuring and managing the connections in a manner that doesn't require a user to physically connect the electronic device to the access point is disclosed. Access Points are set to AP mode upon power up. The electronic device scans the environment for available connections and displays the information in a user interface. The interface displays the topology of the network, the relationship of the access points, and the connection status. Users can easily configure the network and access points wirelessly. All connection information and configuration data is stored in a database on the computer. Users are notified of any incompatibility issues and if any devices are not detected.

  • Publication number: 20080058834
    Abstract: A medical retrieval device includes a basket formed of two or more legs. The basket may be used to retrieve material (e.g., a urinary stone) from a body. The basket opens and closes for encapsulation of a stone. A captured stone may be released from the basket with the basket still in the body by opening the legs. The baskets exhibit shapes and configurations designed to optimize the characteristics of flexibility, ease of material capture, and ease of material release.
