Abstract: Several embodiments of the present invention are generally directed to medical visualization systems that comprise combinations of disposable and reusable components, such as catheters, functional handles, hubs, optical devices, etc. Other embodiments of the present invention are generally directed to features and aspects of an in-vivo visualization system that comprises an endoscope having a working channel through which a catheter having viewing capabilities is routed. the catheter may obtain viewing capabilities by being constructed as a vision catheter or by having a fiberscope or other viewing device selectively routed through one of its channels. The catheter is preferably of the steerable type so that the distal end of the catheter may be steered from its proximal end as it is advanced with the body. A suitable use for the in-vivo visualization system includes but is not limited to diagnosis and/or treatment of the duodenum, and particularly the biliary tree.

Abstract: A two piece electronic component heat sink and device package comprising a first piece configured to retain electronic components, and a second piece having a hinge region configured to moveably connect the second piece to the first piece, and a snap lock region opposite the hinge region, the snap lock region configured to secure the second piece to the first piece. A two piece electronic component heat sink and device package for a circuit board comprising: a first piece having an index slot for retaining said circuit board, and a second piece having a hinge region configured to pivotably connect the second piece and the first piece, and a snap lock region configured to secure the second piece to the first piece.

Abstract: An improved pointer and shaft adapter assembly for use in instruments such as the speedometer of a vehicle including an elongated pointer portion and shaft forming portion connected together by engagement between spaced tabs which project from the pointer lying alongside side wall surfaces of an end connector of the shaft adapter. Cooperative nibs and apertures of the pointer and shaft forming portions secure the parts together and prevent any substantial tilting movement therebetween.
