摘要:
The invention includes a dual lumen catheter which is a unitary, elongated, flexible catheter tube that is substantially circular in cross-section. The catheter tube has an outer wall member forming a tube having a proximal end and a distal end portion adapted for insertion within a vein or artery of a patient. The outer wall member defines first and second coaxial lumens that are separated by an inner common support wall which is substantially circular and joins the outer wall. The first lumen extends longitudinally between the opposed distal and proximal ends of the catheter tube and terminates coextensive with the distal end portion of the catheter tube. The second lumen extends longitudinally from the proximal end of the catheter tube and terminates proximal to the distal end portion of the catheter tube. The second lumen is crescent-shaped in cross-section and substantially surrounds the first lumen. The cross-sectional areas of the first and second lumens are approximately equal.

Disclosed is a dual lumen catheter for insertion within a blood vessel of a patient. The dual lumen catheter has an elongated flexible tube with three conduits contained therein. The first and second conduits are connected together by an opening in the common wall therebetween, which opening extends through the wall of the catheter tube. The third passageway forms a second lumen. Each of the lumens has means adapted for placement of the lumen in fluid communication with a source of liquid to be administered to the patient through the catheter, to means for withdrawing a blood sample or to means for monitoring blood pressure.

A method of making a dual lumen catheter which is a unitary, elongated, flexible catheter tube that is substantially circular in cross-section. The catheter tube has an outer wall member forming a tube having a proximal end and a distal end portion adapted for insertion within a vein or artery of a patient. The outer wall member defines first and second coaxial lumens that are separated by an inner common support wall which is substantially circular and joins the outer wall. The first lumen extends longitudinally between the opposed distal and proximal ends of the catheter tube and terminates coextensive with the distal end portion of the catheter tube. The second lumen extends longitudinally from the proximal end of the catheter tube and terminates proximal to the distal end portion of the catheter tube. The second lumen is crescent-shaped in cross-section and substantially surrounds the first lumen. The cross-sectional areas of the first and second lumens are approximately equal. Each of the first and second lumens are totally smooth internally, thereby containing no ridges or connections which can promote formation of blood clots or cause hemolysis or damage to red blood cells during dialysis. The catheter tube is secured at its proximal end to the distal end of a hollow hub assembly.

A recycling kiosk for recycling and financial remuneration for submission of an electronic device such as a mobile phone is disclosed herein. The recycling kiosk includes electrical connectors and an inspection area with an upper chamber, a lower chamber, a transparent plate and at least one camera in order to perform a visual analysis and an electrical analysis of the electronic device for determination of a value of the electronic device. The recycling kiosk also includes a processor and a display for user interaction.

Devices and methods for removing an obstruction from a blood vessel are described. The devices are deployed in a collapsed condition and are then expanded within the body. The devices are then manipulated to engage and remove the obstruction.
摘要:
A device for temporarily opening a blood vessel is provided. The device has an expandable cage mounted over a shaft having a lumen. The lumen has a distal end, which extends beyond the distal end of the cage so that the lumen provides access to the vasculature distal to the obstruction.

A game of chance includes receiving a stake corresponding to a target game-item from a player. In each phase of the game, a random integer is selected and a game-item corresponding to that integer is removed from play. If the target game-item is removed from play, the player is awarded a return and the game of chance ends. If specific game-items or combinations of game items are removed from play, the player is defeated, and the game of chance ends. A subsequent phase of the game of chance begins if the player is not defeated or awarded a return.

Publishing content using a peer-to-peer content distribution system is described. A publisher is required to request authorization to publish from an authorization body. Resources such as tracker and seed nodes are allocated in a peer-to-peer content distribution system and pre-processing of content to be published is carried out. For example, a content description is generated for each item of content as well as a set of checksums or other items for validating blocks of content. Publication can be terminated in a variety of different ways. For example, by using expiry methods, by active revocation of publishers, authorization bodies, or individual items of content.
摘要:
A quiet, non-binding articulatable spring mechanism for resiliently supporting a mattress includes a system of articulatable, sinuous springs, each having hooked ends for silencing the mechanism during use or collapse, as well as central offset portions for enabling the sinuous springs to compress to a greater extent than heretofore. Both rigid and yieldable support structures connect the spring mechanism to an item of furniture.
