Compression coil provides increased lead control in extraction procedures.

Aims: We investigated a new lead extraction tool (Compression Coil; One-Tie, Cook Medical) in an experimental traction force study.

Methods And Results: On 13 pacemaker leads (Setrox JS53, Biotronik) traction force testing was performed under different configurations. The leads were assigned to three groups: (i) traction force testing without central locking stylet support (n = 5), (ii) traction force testing with the use of a locking stylet (Liberator, Cook Medical) and a proximal ligation suture (n = 4), (iii) traction force testing with the use of a locking stylet and a compression coil (n = 4).

Concept and first experimental results of a new ferromagnetic assist device for extra-aortic counterpulsation.

Objectives: Based on a ferromagnetic silicone cuff for extra-aortic counterpulsation, a new assist device concept was developed. The driving force is generated by an external magnetic field, which leads to contraction of a soft magnetic cuff. The force generation capacity of the device was tested in a silicone aorta model.
