Abstract: An Amplatz sheath for positioning inside a natural or artificially created bodily cavity in a human or animal has a distal end toward the body and a proximal end away from the body, with at least one lumen being formed between the distal end and the proximal end. At least in a region at the proximal end, the Amplatz sheath is transparent or translucent and, in this region, has at least one marking for determining the position of the Amplatz sheath in relation to a catheter that can be received in the lumen. The Amplatz sheath can be used with a balloon catheter in a dilation system.

Abstract: There is presented an interventional device (100), such as a device for minimally invasive surgery, comprising a bag arranged for being transformable between an open configuration and a closed configuration, a shaft (106), a grasper (108) mounted on a distal end of said shaft, wherein the bag further comprises a fluid passageway arranged so that in the closed configuration the fluid passageway enables that fluid may be expelled through the fluid passageway from an interior volume of the bag to an exterior volume of the bag and furthermore enables that a solid element above a predetermined threshold size may be retained in the bag. The fluid passageway may be advantageous for enabling that liquid may be expelled from the bag while larger solid elements, such as a piece of a tumour, may be retained in the bag for removal from a body cavity.

Abstract: An application device has a ureteral catheter with a ureteral catheter main body, a receiving body connected to the ureteral catheter main body by means of at least one connection element of the ureteral catheter, and an introduction component for holding the ureteral catheter and for guiding the ureteral catheter through a ureter of a patient along a pliable guide element. The ureteral catheter can be displaced by means of the introduction component in opposite directions of movement along the pliable guide element and the introduction component is designed to guide the ureteral catheter main body and the receiving body during displacement in the respective directions of movement.

Abstract: For the purpose of firmly clamping a medical guide wire which can be rotated and displaced in a longitudinal opening of an accommodating body, a clamping mechanism is present either just at one end of the longitudinal opening or at each end of the longitudinal opening, the clamping mechanism having a widened opening region, which runs transversely to the longitudinal opening, and a clamping-member arrangement, which is connected to the accommodating body in an elastically flexible manner and has an edge part, which is located in the opening region and against which the guide wire, once pivoted out of the longitudinal opening, can be brought into abutment at the relevant end of the accommodating body and at the clamping-member arrangement, with the capability of the guide wire to be displaced and/or rotated being blocked in the process.

Abstract: A positioning device for a medical catheter to be positioned in a bodily orifice or cavity, the device containing an elongated tubular or sleeve-type catheter receiving member, one end of which receives the catheter to be positioned, elongated catheter release member which is held inside or outside the catheter receiving member and which can be displaced in the longitudinal direction of the member and a motion mechanism comprising a motion conversion device, by means of which the catheter receiving member and the catheter release member can be displaced relative to one another in the longitudinal direction of the device, thus releasing the catheter from the catheter receiving member; the motion conversion device has an actuating member, by means of which motion that is carried out transversely to the longitudinal direction of the device or pivoting motion can be converted into longitudinal motion running in the longitudinal direction of the device.

Abstract: A medical device for inserting into a bodily orifice or cavity of an individual, which includes a first longitudinal hollow body and a second longitudinal hollow body that receives the first hollow body. Between the one end thereof and the first hollow body, there is a stepped transition which extends in the radial direction and can pass into an at least substantially step-free transition by virtue of the fact that the first hollow body, in the region of the stepped transition, expands in the radial direction towards the second hollow body and/or that the second hollow body, in the region of the stepped transition, contracts in the radial direction towards the first hollow body.
