Patent ID: 8639357

Claim:
A percutaneous transluminal vascular intervention (PTVI) device assembly for use during revascularization of a blood vessel, the PTVI device assembly comprising: a stent catheter including a catheter proximal end portion, a catheter distal end portion, an elongate catheter shaft coupled between the catheter proximal end portion and the catheter distal end portion, a first connector at the catheter proximal end portion, and a first conductor electrically connected to the first connector; a stent detachably connected to the catheter distal end portion, the stent including a first electrode to be electrically connected to the first connector through the first conductor; a dissolvable connector connecting between the stent and the catheter distal end portion, the dissolvable connector being electrically conductive and dissolvable by electrolysis after being exposed to blood; a sheath including a sheath proximal opening and a sheath distal opening, the sheath configured to accommodate a portion of the stent catheter and allow the stent to exit through the distal opening; and an external pacemaker configured to be connected to the first connector, the pacemaker including: a pacing output circuit configured to deliver pacing pulses through the first pacing electrode; a control circuit coupled to the pacing output circuit and configured to execute a cardioprotective pacing protocol specifying one or more cardiac protection pacing sequences each including alternating pacing and non-pacing periods, the pacing periods each having a pacing duration during which a plurality of the pacing pulses is delivered, the non-pacing periods each having a non-pacing duration during which none of the pacing pulses is delivered; a chassis housing the pacing output circuit and the control circuit; and a user interface incorporated onto the chassis, the user interface allowing for control of timing of the delivery of the pacing pulses.
