Bifurcated delivery assemblies provide bilateral access to first and second branch lumens extending from a main body space or lumen in a patient. One or more interventional devices are combined with the delivery assemblies for delivery s into one or both of the branch lumens. Bilateral renal stenting or embolic protection procedures are performed using the combination delivery/interventional device assemblies. Fluids may also be injected or aspirated from the assemblies. A bifurcated catheter has a first fluid port located on one bifurcation branch, a second fluid port located on a second branch of the bifurcation, and a third fluid port positioned so as to be located within a vena cava when the first and second ports are positioned bilaterally within first and second renal veins.

A force-sensing catheter for diagnosing or treating the vessels found within a body or body space includes a center strut that is bonded, preferably thermally, along its longitudinal axis with the thermoplastic tubular member within which it is housed. The tubular member preferably has three layers: an inner layer, a braided layer and an outer layer. One or more semiconductor or metallic foil strain gages are affixed to the center strut in order to provide a measure of the bending and torsional forces on the distal tip of the catheter. Temperature compensation is achieved by having a temperature sensor near the strain gages and calibrating the catheter over a range of temperatures.

An access device places a medical article within a body space of a patient. The device has a needle that includes a needle body and hub. The device further includes a dilator coaxially disposed and slideable over the needle body and a medical article. A viewing space is disposed between the dilator and the medical article with at least one passageway or conduit connecting the viewing space with the interior bore of the needle body. The passageway is defined at least in part by openings through the sides of the needle and dilator. At least a portion of the conduit or passageway can be defined by one or more grooves between the needle and dilator. The device can further include a guidewire and an interlock between the guidewire and the needle and/or dilator. The device can further include one or more stops disposed between the guidewire and the needle and/or dilator to limit the extent to which the guidewire can be moved (e.g., advanced) relative to the needle or inhibit such relative movement (e.g., backwards movement).

An access device places a medical article within a body space of a patient. The device has a needle that includes an elongated body, a side fenestration on the elongated body, and a needle hub. The device further includes a dilator disposed on and slideable along the elongated body of the needle and a medical article. The medical article is disposed on and slideable along the dilator. The dilator and the needle form one or more spaces in communication with the side fenestration. At least portions of the dilator and the medical article are configured so as to allow visual determination of the presence of a bodily fluid within the space. The outer surface of the needle and the inner surface of the dilator can include a surfactant. Further, at least one of the needle and dilator can further comprise a vent in communication with the space that allows for the escape of air from the space and inhibits the escape of the bodily fluid from the space.

A shunt rivet for implantation between a first body space and a second body space in a patient, such as to treat chronic obstructive pulmonary disease.

In some embodiments of the invention, an access device can be provided. Advantageously, the access device can enhance the detection of the device's access into a desired body space. For example, the access device may have portions with enhanced visibility to a naked human eye, or an imaging device such as a medical imaging device. Where an imaging device is used, the imaging device can image the access device in a space that usually would not be visible to an operator, such as within a medical patient's body. Where the access device is directly viewed by a human eye, the access device can provide some form of feedback that allows an operator to more quickly discern if the access device has entered a desired space. For example, if the access device is to enter a blood-filled body space, the access device can allow blood to flow up and into the device, and the device can make the blood's presence more immediately apparent. One method of making the blood's (or another fluid) presence more immediately apparent is using a portion with contrasting optical properties.

The invention discloses a user interaction system and a method. The system comprises an information operation processing unit, a three dimensional display unit and a motion capture unit; wherein the information operation processing unit is used for providing three dimensional interface display signals for the three dimensional display unit; the three dimensional display unit is used for displaying a three dimensional interface to a user according to the tree dimensional interface display signals; and the motion capture unit is used for capturing body space mobile information made by the user when the tree dimensional interface is browsed, and sending the body space mobile information to the information operation processing unit. When the user interaction system and the method are applied, the user can indulge in private and interesting virtual information interaction space, and natural information interaction is preformed in the space, so that user interactive experience is enhanced, a large number of meaningful applications can be derived on the basis, and the user is enabled to interact with a digital information world naturally.

An access device places a medical article within a body space of a patient. The device has a needle that includes an elongated body and a needle hub. The medical article is disposed over and slideable over the needle. A flash space is provided anywhere between the needle and the outer surface of the medical article. The flash space communicates with a bore of the needle, as well as a variable volume chamber. The variable volume chamber can then draw fluid from the flash space into the chamber.

A gesture spotting detection method and apparatus employ a shoulder-line algorithm. The shoulder-line detecting method recognizes a GSD calling gesture that occurs in a shoulder-line, head or higher part in a remote distance or a short distance, although a user does not have a fixed posture. In the method, an image of people is received, and skin information of a person in the image is detected to detect a face area. Then, the cloth color information of the person is modeled from the inputted image to detect a cloth area. An external space is defined from the image based on the body space area, and an edge is extracted from the image based on the body space and the external space. Then, shoulder-line information is acquired based on an energy function obtained based on the body space, the external space, and the edge.

A coaxial connector combination is provided having a male and a female portion. The coaxial connector combination includes a female portion having a tubular body with an engagement end and an annular locking groove disposed around an outer surface of the tubular body spaced back from the engagement end and a male portion. The male portion further includes a sleeve, a plurality of pawls, each extending outwards from an engagement end of the sleeve to form an annulate of spaced-apart pawls disposed around a center axis of the sleeve, said annulate of pawls being adapted to engage the outer surface of the tubular body and wherein a catch on an engagement end of each pawl of the plurality pawls engages the annular groove of the female portion and a locking collar disposed around an outside surface of the plurality of pawls and adapted to slidably lock the catches of the distal end of the plurality of pawls into the annular locking groove.
