Various embodiments of a seal for a stent-valve, and methods of production, are described. In some embodiments, the seal or a skirt comprises a fabric wall portion and a polymeric material fused to the fabric wall portion, the polymeric material having a melting temperature that is lower than that of the fabric wall portion. The fibres of the fabric may remain unmelted at the interface with the polymeric material, the polymeric material being attached to material to the fibres of the fabric wall portion by fusion. The polymeric material may provide a welded joint to another fabric wall portion and/or may reinforce the fabric and/or may occlude pores of the fabric.

Stent seals and method of production

A mechanical teleoperated device for remote manipulation includes a slave unit having a number of slave links interconnected by a plurality of slave joints; an end-effector connected to the slave unit; a master unit having a corresponding number of master links interconnected by a plurality of master joints; and a handle connected to a distal end of the master unit. The device further includes first device arranged to kinematically connect the slave unit with the master unit, second device arranged to kinematically connect the end-effector with the handle, and a mechanical constraint device configured to ensure that one master link of the master unit is guided along its longitudinal axis so that the corresponding slave link of the slave unit always translates along a virtual axis parallel to the longitudinal axis of the guided master link in the vicinity of the remote manipulation when the mechanical teleoperated device is operated.

Surgical teleoperated device for remote manipulation

Embodiments of the present disclosure are related to devices and techniques for para-valve sealing of an expandable stent-valve implanted using a catheter. In some embodiments, a stent-valve is provided which comprises a seal sleeve/cuff containing material that swells when contacted by blood. A piercing tool may be included and used to permit a user to puncture the sleeve/cuff prior to introduction into a patient's body. In some embodiments, the sleeve/cuff has an integral tubular structure configured to withstand balloon expansion of the stent-valve during or after implantation. In some embodiments, the seal is provided as a separate component from the stent-valve.
