摘要:
Devices and methods for cooling microwave antennas are disclosed herein. The cooling systems can be used with various types of microwave antennas. One variation generally comprises a handle portion with an elongate outer jacket extending from the handle portion. A microwave antenna is positioned within the handle and outer jacket such that cooling fluid pumped into the handle comes into contact directly along a portion of the length, or a majority of the length, or the entire length of the antenna to allow for direct convective cooling. Other variations include cooling sheaths which form defined cooling channels around a portion of the antenna. Yet another variation includes passively-cooled systems which utilize expandable balloons to urge tissue away from the surface of the microwave antenna as well as cooling sheaths which are cooled through endothermic chemical reactions. Furthermore, the microwave antennas themselves can have cooling lumens integrated directly therethrough.

A solution for generating an installation medium for a program product is provided. A runtime profile for a customer is used to recreate the customer's runtime environment. The program product is installed in the recreated runtime environment and it is tested to ensure that the program product operates as intended in the recreated runtime environment. A custom installation medium is generated based on the installed program product.

A microwave antenna having a curved configuration is described herein. The antenna portion is formed into various shapes whereby the antenna substantially encloses, by a partial or complete loop or enclosure, at least a majority of the tissue to be irradiated. When microwave energy is delivered through the antenna, the curved configuration forms an ablation field or region defined by the curved antenna and any tissue enclosed within the ablation region becomes irradiated by the microwave energy. The microwave antenna is deployed through one of several methods, and multiple curved antennas can be used in conjunction with one another. Moreover, RF energy can also be used at the distal tip of the antenna to provide a cutting tip for the antenna during deployment in tissue.

Various high-strength microwave antenna assemblies are described herein. The microwave antenna has a radiating portion connected by a feedline to a power generating source, e.g., a generator. The antenna is a dipole antenna with the distal end of the radiating portion being tapered and terminating at a tip to allow for direct insertion into tissue. Antenna rigidity comes from placing distal and proximal radiating portions in a pre-stressed state, assembling them via threaded or overlapping joints, or fixedly attaching an inner conductor to the distal portion. The inner conductor is affixed to the distal portion by, e.g., welding, brazing, soldering, or by adhesives. A junction member made from a hard dielectric material, e.g., ceramic, can be placed between the two portions and can have uniform or non-uniform shapes to accommodate varying antenna designs. Electrical chokes may also be used to contain returning currents to the distal end of the antenna.

A method, apparatus, and computer program product are disclosed for selecting links in a page using an enhanced mouse pointer. The page is displayed in a data processing system that includes a mouse that includes a scroll wheel. Multiple links are included in the page. A standard mouse pointer is displayed in the page. An enhanced mouse pointer state is then invoked causing the standard mouse pointer to become an enhanced mouse pointer. In response to invoking the enhanced mouse pointer state, a closest one of the links in the page to the enhanced standard mouse pointer is determined. An enhanced mouse pointer indicator is displayed that extends from the enhanced mouse pointer to the determined closest one of the links. The links may be scrolled through by rotating the scroll wheel.

A portal environment may include at least one detachable and reattachable portal page. The detachable and reattachable portal page may include a detach feature to detach the portal page from the portal environment. A reattach feature may be provided to reattach a detached portal page to the portal environment. In another embodiment, a method to detach and reattach at least one portal page may include detaching a selected portal page in response to activating a detach feature. The method may also include reattaching the detached portal page in response to activating a reattach feature. The selected, detached portal page may be transferred to a window in response to activating the detach feature. Tunneling communication may be provided between the detached portal page and the portal environment.
