Abstract: The invention provides a flow device for creating a flow of bubbles of a contrast medium. The device comprises a pump which is configured to provide a flow of the medium and an elongated insertion tube attached to the pump at a proximal end. The elongated insertion tube forms a flow path between the proximal end and an outlet at a distal end.

Abstract: The present invention concerns a prefilled injection device having a container and a dose setting mechanism encapsulated inside a housing. The injection device incorporates an axial variable connection such that a distance between a distal end of a piston rod and a plunger is minimized preferably to zero.

Abstract: A device for visualization of internal tissue of a patient's uterus having a hand-held control unit, an elongated member, and an image capturing tip. To increase the manoeuvrability of the image capturing tip, the elongated member forms a straight portion extending along a straight axis and a curved portion forming a curvature away from the straight axis, the curved portion being between the image capturing tip and the straight portion. By rotation of an inner tube in an outer tube, the image capturing structure will move along a circular path without being rotated about the centre axis of the elongated member.

Abstract: A device for visualization of internal tissue of a patient's uterus, the device having a control unit, elongated member extending in an axial direction between a proximal end and a distal end, and image capturing tip. The proximal end is connected to the control unit and the distal end is connected to the image capturing tip. The image capturing tip communicates electric video signals with a monitor. At least the distal end of the elongated member and image capturing tip are dimensioned for insertion into the patient's uterus through cervix. The image capturing tip has a housing, digital imaging device, lens, and at least one light source. To provide slim design and improved capability for insertion into the uterus, the digital imaging device is arranged between the light source and lens, and has a light guide configured to direct light from the light source around the digital imaging device.

Abstract: The invention relates to an injection device (100, 200, 300) which is capable of resisting proximal movements of a piston rod (107, 207, 307) relative to a housing (102, 202, 302), when the piston rod (107, 207, 307) is subjected to proximally directed forces below a threshold magnitude, and of allowing reversible proximal movements of the piston rod (107, 207, 307) relative to the housing (102, 202, 302), when the piston rod (107, 207, 307) is subjected to proximally directed forces of or above the threshold magnitude.

Abstract: The invention relates to an injection device (1, 100) configured to perform automatic priming upon removal of a protective cap (15, 115) from a cap receiving portion (9, 109) of a housing (2, 102). When mounted on the injection device (1, 100) the cap (15, 115) defines a first position for a drive member (10, 110) relative to the housing (2, 102), which drive member (10, 110) is capable of causing a piston rod (7, 107) to advance a piston (8, 108) in a reservoir (4, 104). Means (13, 120) are provided defining a second position for the drive member (10, 110) relative to the housing (2, 102). During removal of the cap (15, 115) from the cap receiving portion (9, 109) the drive member (10, 110) moves from the first position to the second position under the influence of a spring (11, 111), thereby causing the piston rod (7, 107) to pressurize the reservoir (4, 104).
