Further, a set of instruments is provided which comprises a needle (10), a stitching device (30) and a clamping device (20) comprising a first jaw (21a) which is frame-like configured permitting the tip portion of the needle (10) to penetrate the first jaw (21a) and a second jaw (21b) with a cavity (29) configured to receive the tip portion of the needle (10).

Disclosed adjustable retaining arm systems can include a multi-segmented, articulable arm that holds one or more interchangeable tools and can be made relaxed to set a desired position and made rigid to fix the desired position by adjusting tension in a cable running through the arm. The arm can quickly attach and detach from a support structure. The support structure include a cable tensioning system, sensors, control system, power system, etc. A user input device, such as a foot pedal or button on the arm, can be used by a surgeon to change the arm between relaxed and rigid states. The arm and attachable tools can be detachable, disposable and/or sterilizable, while other system components can remain mounted in a fixed location as the arm is removed and replaced. The arm can hold multiple tools in any desired orientation around subject work location.

Stepper motor with a housing 1,2,4,6,16, in which a cylindrical rotor 11,15 fixed on a central shaft 12 can rotate but not translate along an axial direction. There are cylindrical translators 9, 14 on both sides of the rotors 11, 15, where the translators 9, 14 are sealed fit in a cylindrical space within the housing 6 and around the central shaft 12 and where the translators 9, 14 can only translate in an axial direction, where in one axial position of a translator 9, 14 a set of triangular asymmetric teeth 20 located on the translator 9, 14 can interact and fit into a set of triangular asymmetric teeth 21 on the rotor 11, 15, where the shape of the teeth 21 on both sides of the rotor 11, 15 is symmetric and where one of the sets of teeth 20, 21 between one translator 9 (14) and the rotor 11 (15) and a set of teeth 20, 21 between the other translator 9 (14) and the rotor 11 (15) are tangentially shifted, i.e. offset over a length equal to half the width of a tooth 20, 21 and where the translators 9, 14 can be moved by a pressure difference between the part of the cylindrical space between the housing 6 and a translator 9, 14 and the part of the cylindrical space between the translator 9, 14 and the rotor 11, 15.

The present disclosure relates to a dynamic-seal-less self-actuating growing rod system (100) comprising at least one cylindrical static rod (2), at least one piston rod (6), coaxially coupled with said static rod (2) and configured to distract longitudinally out of the static rod (2); at least one fluid source (8) holding at least one sterile biocompatible fluid at a pre-determined pressure; at least one fluid transfer port (10) configured to transfer said sterile biocompatible fluid in said fluid source (8) to at least one fluid receptacle (12) at the same pre-determined pressure, wherein said at least one fluid receptacle (12) is in contact with said second piston end (6b) of said piston rod (6) at a first receptacle end (12a) and is connected to said fluid transfer port (10) at a second receptacle end (12b).

Methods and devices are provided for the alleviation of pain during childbirth. Generally, the methods and devices are designed to apply pressure to the hips of a female during the labor process. These devices may be manually or automatically actuated to provide pressure to the hips of a patient and the devices may further include force limiting devices to ensure that excessive forces are not applied to the patient.

The invention relates to a fastening device for implant device, the fastening device comprising at least two fastening sections, where a first fastening section is arranged with a through hole, a second fastening section is arranged with a protruding part, and where said protruding part is in place in said through hole in a fastening device locking state, where the protruding part on the second fastening section is arranged with a through channel having an inlet and an outlet, said through channel being arranged to receive an implant device feed member, said inlet and outlet being accessible from the exterior of the fastening device in said fastening device locking state, wherein the first fastening section is securely locked to the second fastening section when, in said fastening device locking state, said implant device feed member is in place in the through channel and protrudes from both the inlet and the outlet of said through channel. The invention further relates to an implant device comprising a fastening device, and a method for securely locking a first fastening section of a fastening device for an implant device to a second section of a fastening device for an implant device.

Diffusion and infusion resistant implantable devices and methods for reducing pulsatile pressure are provided. The implantable device includes a balloon implantable within a blood vessel of a patient, e.g., the pulmonary artery. The balloon is injected with a fluid mixture comprising a constituent fluid(s) and a diffusion-resistant gas to provide optimal balloon volume and limit fluid diffusion throughout multiple cardiac cycles. The fluid mixture may be pressurized such that the balloon is transitionable between an expanded state and a collapsed state responsive to pressure fluctuations in the blood vessel.

A device for applying external pressure on a surface of an anatomical object, such as a blood vessel, includes at least two jaws, a closing force generating device for applying compressive or closing force to the jaws so to driving the jaws against each other. The device also includes an actuating device for applying counterforce against the compressive force, and a control unit. The control unit controls the operation of the actuating device to apply the counterforce so that the external pressure applied by the jaws into the surface of the anatomical object, such as a blood vessel, is applied in a way to manipulate a flow rate of a fluid circulation in the anatomical object as a function of time in a controllable manner.
