摘要： In one general aspect, a medical device can include a base having a guide and a handle. The medical device can also include a needle member that has a curved portion and a handle portion. The curved portion of the needle member can be configured to slidably move within the guide of the base from a first position to a second position different than the first position when the handle portion of the needle member is moved towards the handle of the base.

摘要： A medical system includes a catheter having an elongated tubular member and an inner core slideably received within the elongated member. The inner core includes an imager on a distal end and is coupled with a control system and an imaging system. The inner core is configured to scan the interior of a lumen by radially rotating around a center axis and axially translating along the center axis while within the elongated member. The medical system is configured to dynamically image a body lumen at a high speed in order to allow for optical imaging in a safe manner without long durations of blood sequestration and displacement. The medical system is configured to obtain three dimensional images of the body lumen with as little as one dimensional scanning of the lumen. Images of the lumen can be stored and viewed at a desired rate after scanning.

摘要： The present invention is directed to a scanning system that uses uniform rotary motion of an optical reflector to create reciprocal linear scanning. The system converts uniform rotation into uniform longitudinal scanning. The system thereby creates mechanical reciprocal linear scanning free of reciprocally moving mechanical parts common in conventional scanning systems. In a preferred embodiment of the invention, the scanning system is incorporated within an imaging catheter for medical scanning. The optical reflector is rotatable and includes a spiral reflecting portion. The spiral reflecting portion may be a single uniform reflecting surface or may include several reflection surfaces arranged in a spiral configuration.

摘要： An articulating mechanism for use in a medical device, such as an endoscope or a catheter, includes a series of stacked links disposed adjacent to one another and movable with respect to each other. Each link includes a front face tapered to a pair of pivot points and a rear face defining a wedge shaped recess for receiving the pivot points of the adjacent link. Pull-wires provide tension and hold the staked links together while also allowing for controlled bending of the distal portion by movement of one or more of the pull-wires.

摘要： An ultrasound transducer having an acoustic backing layer made of an aerogel material is disclosed. The ultrasound transducer comprises an acoustic element for transmitting and receiving ultrasound waves. An aerogel acoustic backing layer is bonded to the back side of the acoustic element. A matching layer may be attached to the front side of the acoustic element. The ultrasound transducer may be electrically connected using electrodes directly connected to the acoustic element. Alternatively, the aerogel acoustic backing may be coated with a metalized layer or doped so that it is electrically conductive. Then, the electrodes may be connected directly to the aerogel acoustic backing.

摘要： The invention features a medical guidewire constructed for insertion into the body for providing access to a body passage. The medical guidewire has a main proximal portion in the form of an elongated tube extending the majority of the length of the guidewire, and a distal tubular portion integral with the main proximal portion. The distal portion includes a distal end and a flexible section having a slot cut in the wall of the distal tubular portion. The slot crosses the right sections of the distal tubular portion at an oblique angle and extends continuously about the distal tubular portion, in excess of at least one rotation about the distal tubular portion, to increase the flexibility of the distal tubular portion with respect to the main proximal portion.

摘要： A hand-holdable steering mechanism is used as part of a medical device such as a catheter or an endoscope to allow movement of a steerable distal portion of the catheter or endoscope. The mechanism can include a housing and an actuation system. The actuation system is adapted for one-handed operation by a user, and it allows the user to achieve 360 degree articulation of the steerable distal portion. The actuation system can include a first actuator and a second actuator where the first and second actuators are movable with respect to each other. The first actuator can be at least partially disposed within the second actuator.
