摘要： The present invention provides ultrasound imaging catheters, systems and methods for their use which will be particularly useful to monitor the positioning of ablation catheters. In one embodiment, an imaging catheter (10) includes a catheter body (11) having a distal end (12), a proximal end (14) and a longitudinal axis (16). A transducer (20) is rotatably coupled to the distal end. The transducer has an axis of rotation (24) that is at a non-zero angle relative to the catheter body longitudinal axis. Such a configuration provides an exemplary side-looking imaging catheter.

摘要： The system (2) includes a catheter drive unit (22) and a catheter (24) extending therefrom movably mounted to a catheter drive sled (26). The catheter drive unit rotates and translates the catheter core (34) within the catheter sheath (36). The sled has a serrated, conical drive unit interface (82), with a bag-piercing tip (86) mateable with a translator drive output (92) so that a sterile drape (112) enclosing the catheter drive unit is automatically pierced when the catheter drive unit is mounted to the sled. A control unit (6) is spaced apart from the catheter drive unit and provides power and commands to the catheter drive unit and receives information and data from the catheter drive unit. The rotator and translator drive motors (54, 90) are operated from both the control unit and the catheter drive unit. Both the control unit and catheter drive unit have translation displacement displays (10, 30).

摘要： Devices, methods, and systems for treating Type-2 Diabetes and/or obesity by facilitating the delivery of under-digested nutrients within the gastro-intestinal tract without substantial tissue removal are disclosed. In one aspect, the gastro-intestinal tract of a patient is modified by a gastro-intestinal treatment device comprising an elongate element configured to extend within the gastro-intestinal tract, a first attachment element and a second attachment element disposed on the elongate element, wherein the first attachment element and the second attachment element are configured to attach to the gastro-intestinal tract such that a portion of the gastro-intestinal tract is compressed between the first and the second attachment elements. The length of the gastro-intestinal tract modified by the device is effectively shortened, and its surface area is reduced.

摘要： A method for assessing lung function in a patient is disclosed. The method comprises isolating a lung compartment. Thereafter, in one embodiment, an inhaled gas of known composition is introduced into the lung and compared to the composition of the exhaled gas. Alternatively, accumulated CO2 content is measured within the isolated lung compartment over time, and compared to a baseline CO2 content. Alternatively, a change in pressure of an isolated lung compartment may be monitored. Alternatively, the magnitude of the range of CO2 values in an isolated lung compartment can be compared to a predetermined threshold. Any of the results obtained via these alternative embodiments may be used to determine lung function.

摘要： A device for safely accessing bone marrow and other tissues is disclosed. Such device comprises a needle assembly, a sensor mechanism, and an actuator configured to engage with the needle assembly via the sensor mechanism to advance a tissue penetrable needle through a first tissue region and into a second tissue region. In one aspect, the first tissue region is a bone cortex and the second tissue region is a bone marrow cavity. The sensor mechanism is configured to disengage the actuator from the needle once the needle has crossed the first tissue region (e.g., bone cortex) into the second tissue region (e.g., bone marrow cavity), thereby preventing the needle from advancing further into the second tissue region. In one aspect, the sensor mechanism is mechanical and comprises a pin assembly comprising a spring-loaded pin that extends through the needle. The pin assembly is configured such that advancement of the distal tip of the spring-loaded pin past the distal tip of the needle causes the actuator to disengage from the needle. The actuator is a rotatable actuator. A catheter-based embodiment of the device can be inserted in body passageways to access tissue internally within the body.
