Abstract: A convertible nephroureteral catheter is used in the treatment of urinary system complications, particularly on the need for a single surgically delivered device to treat patients who must be seen by an interventional radiologist (IR). In many current procedures, patients need to return to the operating room to remove a previously delivered nephroureteral catheter to exchange this catheter with a fully implanted ureteral stent delivered though the same access site at the flank. The present convertible nephroureteral catheter reduces the need to return for a second surgical procedure. Two weeks after initial implantation, the proximal portion of the convertible nephroureteral catheter extending out from the body may simply be removed. A simple action at the catheter hub allows this proximal portion to be removed, leaving behind the implanted ureteral stent within the patient's urinary system. Other medical procedures, devices, and technologies may benefit from the described convertible catheter.

Abstract: A search engine system (1) capable of displaying indicative information (3) to a user from searches performed by entities connected directly or indirectly to the user (2), wherein said system (1) includes at least one host computer processor (23) connectable to one or more network(s) (24), a database accessible over said network(s) (24), a plurality of data input devices (25) connectable to said network(s) (24) said search engine being accessible over said network(s) (24).

Abstract: A search engine (1) capable of providing a listing of destinations (4) in response to searches for a user-inputted search term (6), said search engine (1) further providing at least one suggestions (10) listing derived from users previously inputted search terms (6) and/or destinations (4) selected, characterized in that at least one seeded suggestion (15) is incorporated in at least one suggestion (10) listing.

Abstract: An adaptive search engine (1) having a plurality of data items (4) from one or more data sources (5) stored in at least one database searchable by a search query (6) of a least one keyword (7) to produce a corresponding ranked search result listing (8) of data items (4), said search engine having a plurality of selectable filters (9) applicable by the search engine and/or the user to filter at least a portion (10) of the data items (4) of the search result listing (8), characterised in that said search engine records an association between a filter (9) applied to a search query (6) and a data item (4) selected by a user from said filtered portion (10) of the corresponding search result listing (8), wherein each recorded association contributes to the weighting given by the search engine (1) to application of said filter (9) in a subsequent search for at least one keyword (7) of said search query (6).
