A supply connection device for a fluid pressure system, the connection includes a head designed to be axially received in a body of a supply intake, and the connection is capable of being locked in a front position axially engaged in the supply intake body by a locking mechanism, which includes a globally symmetrical U-shaped pin with two transverse locking branches. The connection is unlocked from the body, for axially releasing, at least partly, rearward the connection outside the body, by elastic deformation of the locking mechanism which results from the co-operation between at least a part of the locking branches and at least a part of the body under the action of a releasing force exerted on the locking mechanism along a transverse direction. The elastic deformation is obtained by exerting a releasing force thrusting a connecting section of the two braches of the pin.

A system and a method of performing a frameless image-guided biopsy uses imaging, a six-dimensional robotic couch system, a laser guidance system, an optical distance indicator, and a needle control apparatus. A planning CT scan is made of the patient with stereotactic fiduciary markers to localize and produce digitally reconstructed radiographs. Two stereoscopic images are generated using an imaging device to visualize and identify a target tumor. The images are fused with the digitally reconstructed radiographs of the planning CT scan to process tumor location. The tumor location data are communicated to the movable robotic couch to position the target tumor of the patient at a known isocenter location. A biopsy needle is guided with a laser alignment mechanism towards the isocenter at the determined depth using a needle positioning apparatus and an Optical Distance Indicator, and a biopsy sample of the target tumor is obtained.

A suture sleeve for securing an implantable lead to body tissue has a lumen that receives the lead and that includes a locking arrangement that secures the sleeve at a selected position along the lead. The locking arrangement provides the suture sleeve with three modes of operation. In the first mode, the size of the lumen exceeds the diameter of the lead, such that the suture sleeve is easily movable along the lead. In the second mode, the size of at least a portion of the lumen is reduced, causing the sleeve to apply pressure to the lead so that relative movement between the sleeve and the lead is prevented. In the third mode, the pressure is temporarily released, allowing the sleeve to again be movable along the lead.
