Abstract: An insertion tool for inserting a catheter into a patient's body includes a housing in which at least a portion of the catheter is initially disposed, a hollow needle distally extending from the housing with the catheter pre-disposed over the needle, and a guidewire pre-disposed in the needle. The insertion tool can include a guidewire advancement assembly that can include a first finger pad for selectively advancing the guidewire distally past a distal end of the needle in preparation for distal advancement of the catheter. The insertion tool can further include a catheter advancement assembly that can include a second finger pad for selectively advancing the catheter into the patient. The first and second finger pads can be positioned such that a user can begin to advance the second finger pad after advancing the first finger pad without substantially re-positioning the thumb or finger of the user.

Abstract: An upright reactor body with a perforated interior tube member which extends for the length of the reactor body. A water inlet permits water to be treated into the perforated tube member. A fibrous metal anode surrounds the perforated tube member followed by a surrounding layer of dielectric and then a surrounding metal cathode layer, wherein water from the inlet passes radially through the perforations in the tube member, through the anode, dielectric and cathode members, emerging from the reactor body through an outlet. A DC voltage is imposed on the cathode and anode.

Abstract: An artificial joint, generally, can have natural load transfer capabilities. The joint includes a first component having a first articular surface and a rotation device, and a second component having a second articular surface for mating with the first articular surface and a rotation device receptacle. The first component is matable to the second component through cooperation of the rotation device and the rotation device receptacle. The first component can cooperate with the second component in contact of the first and second articular surfaces and in articulation of the joint when the first component is mated to the second component. The joint can be embodied as a knee prosthesis; therein, the first and second components are femoral and tibial components, respectively, with the first articular surface being termed a condylar surface and the second articular surface being termed a condylar mating surface. The joint, especially the rotation device, may be made of metal.
