This disclosure relates to sorbent bags that is used in the purification and regeneration of a dialysis solution. Each sorbent bag comprises a sorbent material in a reinforced plastic sealed portion with luer extensions and clamps to facilitate the inlet and outlet of the dialysate solution and to facilitate the mechanism of operation. Furthermore, each sorbent bag has recharge/reactivation line with luer and a vent line. The recharge/reactivation line with luer is located at the inlet line of the sorbent bag at its distal portion before a porous portion. While a vent line is located at the outlet line of the sorbent bag after a second porous portion. Each sorbent bag has shape that is gradually increased in diameter until a diameter āDā and then gradually decreased in diameter through the remaining length of the bag in the direction of the fluid flow.
A system to be used in a tumor treatment, comprises a trocar, a device and connection cables. A trocar that is used to puncture a patient's body at entry site to a tumor location, comprises a first portion with a cutting edge and a heat generating element, an elongated body and a second portion. A device that is connected to a trocar to provide a heat generating element of a trocar with a necessary energy. A device has a radiofrequency current generator to supply and control the energy supplied to a heat generating element.In operation, there are two steps, in a first step, a trocar is inserted into a tumor location, then a salty solution is pump within a tumor area via a syringe and oblique ports of a heat generating element to cause tumor's cells to shrink. Then after a shrink effect a salty solution is sucked via a syringe. In a second step of operation, a higher temperature may be achieved in cancer cells via the activation of a heat generating element to produce a precise and adequate temperature intracellularly to kill cancer cells.
A device to be used to destroy cancerous cells comprises a modified syringe with an ultraviolet radiation source. A modified syringe comprises a hollow syringe barrel including a fluid chamber, a plunger movable on advanced and retracted position slidably disposed within a fluid chamber, an ultraviolet radiation source that is fixed longitudinally through hollow syringe barrel and a plunger.An ultraviolet radiation source fixation seal including two apertures disposed within a fluid chamber to permit a photoactive agent to flow from its container into a fluid chamber through the two apertures. Then, a photoactive agent in a fluid chamber is activated with an ultraviolet radiation that is emitted from an ultraviolet radiation source before it is injected directly to a cancerous cells' location using a modified syringe which is acting as an ordinary syringe.
Pen Like Device For Detecting Cancerous Cells During Surgery
A pen like device for contactless imaging of the electrical conductivity of a target tissue during a surgery to different between cancerous cells and normal cells. The device operation is based on the principal of conductivity imaging by a magnetic induction. The device has a cylindrical transmitter coil and two receiver coils that are wound on a cylindrical rod of an electrically insulating material. The measured contactless conductivity through a non-electrically conductive wall of the device's body is displayed on a rotatable screen to help surgeons to make immediate decisions during a surgery.
System For Its Use In The Treatment Of Vascular Stenosis And Occlusions
A system to be used inside a dialysis unit for dilating obstructed blood vessel, comprises a catheter, a device, a remote-control box, supportive components and connection cables. A catheter comprises an elongated portion, a proximal end and a distal end, extended longitudinally. A distal end of a catheter has a convectively heating tip with a heat generating element and an inflatable balloon. A device has a radiofrequency current generator to supply and control a heating process of a heat generating element of a catheter tip. A remote-control box comprises a valve assembly, a heat activation switch and a balloon inflation switch to facilitate a treatment process.
A multilumen curved split-tip catheter comprises a proximal end, a distal end and an elongated portion arranged between a proximal end and a distal end, defining a longitudinal axis. Elongated portion includes triple lumens for a blood flow therethrough, two arterial lumens and one venous lumen. The triple lumens are fixed to make a venous lumen is located between two arterial lumens along the length of the catheter to two dividing points. Also, the triple lumens are not at the same level with respect to each other inside a blood vessel after insertion. Each lumen extends between a distal end and a proximal end and includes a port at a distal end thereof in a communication with the lumen. Distal end has three curved distal segments that are splitted (separated) from each other with respect to a longitudinal axis.
A hemodialysis self-centric symmetric catheter comprises an elongated portion, a proximal end and a distal end defining a longitudinal axis. Distal end may have two distal segments that may split (separated) from each other with respect to a longitudinal axis at a proximal end of said two distal segments and re-bonded with a distal portion at a distal end of said two distal segments. Each distal segment has a curved portion. Proximal end of said two distal segments may be coupled with a distal end of elongated portion. First distal segment and second distal segment are exactly symmetric (similar) to each other. Each distal segment may have a lumen, a distal tip and a distal angled opening.
A hemodialysis curved split-tip catheter comprises an elongated portion, a proximal end and a distal end defining a longitudinal axis. The proximal end attaches to a hub with suture wings assembly, which in turn connected to extension tubings. The distal end has two distal tip segments splitted from each other. The distal tip segments bend longitudinally inward toward a centerline of a blood vessel. First distal tip segment has a smaller angle, with respect to the axis extended from the dividing point longitudinally parallel to a centerline axis of a blood vessel, compare to second distal tip segment. This configuration to make the distal end of the catheter to be located not at the centerline axis of a blood vessel.
