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 medical device such as a catheter or endoscope device includes an illumination light source having one or more organic light-emitting diodes (OLEDs). The OLEDs are energized to produce illumination light that is received by an image sensor or camera to produce images of tissue within a patient's body. A heat conductive polymer conducts heat away from the illumination light source.
Abstract:
Embodiments of the invention are directed to a medical device and methods for collecting a tissue sample from a patient's body. The device may include a first tube defining a lumen and an aperture at a distal end of the first tube. A second tube extends within the lumen of the first tube and defines a lumen and slots, where at least some of the slots have sharp edges configured to shear tissue. The second tube is movable relative to the first tube such that the sharp edges cut a plurality of samples from tissue disposed within the aperture.
Abstract:
Embodiments of the invention include a sleeve for use in a body lumen defined by body tissue. The sleeve includes a collapsible wall defining a lumen and including an inflatable member configured to increase a volume of the lumen when the inflatable member is in an inflated state, a conduit configured to inflate the inflatable member, and a port defined by the collapsible wall and in flow communication with the lumen.
