The present invention relates to a shape-controllable catheters and catheter systems. Shape-controllable catheters (100, 200, 300, 400, 500) are provided that are versatile in application and that, in human-imaging applications, minimize or reduce patient discomfort. One such catheter is provided with at least one control wire (121, 123) that extends inside the catheter and a control mechanism (611, 613) for tensioning the control wire to produce in the catheter a humped shape or a cantilevered configuration. Hardness of the catheter may be varied along the length thereof to facilitate desired bending. For example, hardness may be reduced in bend areas. Hardness may be maintained or increased in other areas for performance reasons, for example to maintain planarity of an imaging array.

An electronic MEMS device is formed by a chip having with a main face and bonded to a support via an adhesive layer. A cavity extends inside the chip from its main face and is closed by a flexible film covering the main face of the chip at least in the area of the cavity. The support has a depressed portion facing the cavity and delimited by a protruding portion facing the main face of the chip. Inside the depressed portion, the adhesive layer has a greater thickness than the projecting portion so as to be able to absorb any swelling of the flexible film as a result of the expansion of the gas contained inside the cavity during thermal processes.

Systems and methods that prevent oxygen inhibition of a light-initiated polymerization reaction by forcing the oxygen away from the reaction surfaces. In some embodiments, oxygen is purged by bringing a planarizing surface (e.g., a thin transparent film and/or a transparent planar surface) into contact with a layer of UV curable material disposed on a workpiece and then moving the planarizing surface away from the workpiece one the UV material is cured.
