Implantable apparatus includes two or more alignable marker elements, and systems and methods for manufacturing such implantable apparatus, and methods to utilize such implantable apparatus. For example, the implantable apparatus may include a first alignable marker element and a second alignable marker element that may be used to ensure proper alignment with a target site.

A gas-fired atmospheric pressure steam humidifier having high efficiency and ultra-low NOx(3) emissions is disclosed. In some examples, the gas-fired humidifier can have an efficiency of greater than 90 percent and a NOx(3) output of less than 20 parts per million (ppm). In one aspect, the humidifier includes a secondary heat exchanger having a first heat exchange section for pre-heating combustion air and a separate second heat exchange section for pre-heating make-up water, wherein the first and second heat exchange sections are in heat transfer communication with exhaust gases generated by the gas-fired burner and combustion blower assembly. In some examples, the first heat exchange section includes orifices for enabling flue gas recirculation.

A steam dispersion system includes a header defining a first end and a second end, a plurality of steam dispersion tubes extending upwardly from the header, a condensate drain outlet located at the first end, a hollow pipe positioned within the header, the pipe defining a length extending in a direction generally from the first end to the second end, the pipe defining a main humidification steam inlet located at the first end and a main steam outlet that is within the header. The hollow pipe is configured to receive steam flowing in from the main steam inlet toward the main steam outlet. The pipe may define a plurality of orifices along the length thereof for allowing steam flowing through the pipe to enter the header for distribution through the dispersion tubes. A steam re-direction structure directs steam flow leaving through the main steam outlet back toward the first end of the header.

A pump assembly comprises a base, a cam, a cylinder, a piston, and a shim clip. The cam rotates about a rotational axis with respect to the base. The cylinder attaches to the base, and has an inlet port and an outlet for fluid. The piston is reciprocally driven by rotation of the cam to draw fluid into the cylinder through the inlet port during a fill stroke, and to close the inlet port and pump fluid in the cylinder toward the offset during a pump stroke. The shim clip is removably insertable between the cylinder and the base to increase the distance between the inlet port and the rotational axis.

Removable shim clip for adjustable piston pump

A pump assembly comprises a cam and a piston. The cam rotates in a plane about an eccentric axis, and has a circumferential side wall. The piston engages the circumferential side wall of the cam, and runs along a piston axis which lies in the plane of the cam. The piston axis is parallel to but not coincident with a reference line perpendicular to and intersecting the eccentric axis.
