摘要:
A catheter assembly may be provided with a catheter body and an inflatable balloon. The catheter body has a proximal end, a distal end and a balloon inflation lumen. The inflatable balloon is attachable to the distal end of the catheter body. The balloon has an inner surface that at least partially defines an interior volume. The balloon is configured such that the interior volume can be in fluid communication with the inflation lumen of the catheter body to inflate the balloon. The balloon also has a proximal surface and a distal surface. The balloon is provided with a channel that extends through the balloon. The channel is configured to provide fluid communication between the proximal surface of the balloon and the distal surface of the balloon. Other catheter assemblies and methods of use are also disclosed.

Tissue anchors comprise a woven filament braid body having an elongated tubular configuration and a foreshortened configuration where proximal and distal ends of the body expand radially into double-walled flange structures while leaving a cylindrical saddle region therebetween. The tissue anchors are deployed through penetrations between adjacent tissue layers, where the flanges engage the outer surfaces of the tissue layers and the saddle region resides within the tissue penetrations.

A method for increasing golf course revenues through increased sales of consumable items, comprising the steps of stocking a golf cart with a supply of consumable items prior to a golfer's use of said golf cart in a golf outing, taking inventory of said supply of consumable items contained in said golf cart at the end of said golf outing to determine what items were consumed by said golfer, charging said golfer for the cost of the consumable items consumed by said golfer during said golf outing, and restocking said golf cart with a supply of consumable items. The present invention also relates to an apparatus for increasing golf course concession revenues through sales of consumable items, comprising: a base section having insulation means, an inner and outer surface, a substantially closed bottom end, an open top end, one or more slotted flanges disposed on said outer surface of said base section for fastening said apparatus to a golf cart, and an inwardly tapered ledge disposed horizontally on said inner surface of said base section near said base section's upper edge; a removable pull-out container configured to fit within said base section and rest on said inwardly tapered ledge of said base section; an upper section having an open bottom end, a vertical wall area having an inner and outer surface and an access opening disposed thereon for access to items stored in said pull-out container without having to disassemble said apparatus, a side door connected to said upper section's vertical wall area covering said access opening, and a bottom edge compatibly grooved to couple with and rest on said upper edge of said base section; a top lid configured to fit over said open top end of said upper section; and an upper tray disposed within said upper section near said upper section's upper edge. The apparatus of the present invention is employed in the method of the present invention by being stocked full of appropriate consumable items by the golf course operator prior to each golf outing, being installed in the rear basket section of the typical golf cart to provide easy access for golfers to a supply of such items on demand, being inventoried by the golf course operator after completion of the golf outing to identify the items consumed by the golfer during his or her golf outing, charging the golfer for the costs of such consumed items (either separately or as part of the golfer's total bill), and restocking the apparatus with a full supply of consumable items after the golf outing is completed and the golf cart is returned to the golf course operator, so that the method can be repeated with the next golfer renting the particular golf cart.
摘要:
Methods and devices are provided for carrying out assays with minimal technical training where quantitative visual determinations may be made. The devices provide for a flow-path where a sample receiving element is moved from a sample receiving position to a position where it serves to bridge a transport element and a measurement element, so that the sample may be transported from the sample element to the measurement region. Labelled conjugates are provided which migrate a distance into the measurement region related to the amount of analyte in the sample.

A high torque vascular catheter system includes an inner catheter, a proximal outer catheter section, a distal outer catheter section, at least one discrete connection point connecting the inner catheter to the proximal outer catheter section, and at least one discrete connection point connecting the inner catheter to the distal outer catheter section. The distal outer catheter section is more flexible than the proximal outer catheter section. Methods of construction and use of the catheter system are also disclosed.

The present invention relates to a dry reagent assay device having at least one test zone and at least one reference zone, which provides an internal mechanism for assuring correct and reliable assay procedures and reagent qualities. In one embodiment, the present invention relates to an assay device having at least one test zone for detecting at least one analyte in a sample by reacting the sample with a labeled indicator reagent, and a reference zone for receiving unreacted labeled indicator reagent.

A translumenal access system includes a translumenal access catheter, a trocar, and one or more guidewires. The trocar may be introduced through adjacent tissue layers, typically from an endoscope, and the translumenal access catheter introduced through the resulting penetration over the trocar. A balloon on the catheter may be used to dilate the penetration, and an enlarged distal portion of the balloon may be used to draw the tissue layers into apposition. The first stent may be exchanged for the trocar and a second stent may be introduced through a side port on the access catheter. The stents may be then used to introduced catheters or other interventional tools, optionally for delivering one or more stents to the enlarged tissue penetration.
