Percutaneous introducer and associated balloon catheter
First Claim
Patent Images
1. A percutaneous translumen introducer for a balloon catheter, comprising:
- a.) an introducer holder;
b.) a hemostasis valve providing suction means for removal of dye and embolus material arising from dilation of a lesion of a plaque site; and
, c.) means for securing the introducer holder to the hemostasis valve to prevent backward movement of the introducer holder during movement of the holder.

Abstract
A balloon catheter construction for percutaneous use is provided employing a balloon polymer material bonded to an introducer shaft with a bonding agent comprising a low molecular weight oligomer corresponding to the higher molecular weight polymer of the balloon. The oligomer functions alone or together with a primer which enables bonding to the shaft during heat curing, thereby securing the balloon thereon. The balloon introducer catheter is designed to effectively block emboli material which are released from say a plaque rupture, or other site and to then to remove such material by suction from a blood vessel such as a vein or artery.

3. A percutaneous translumen introducer, comprising a balloon introducer;
- an insertion introducer shaft;
a silicone dilation balloon mounted on the introducer shaft for insertion into a vein or artery following the introducer, the dilation balloon being coated along the introducer shaft and extending backwards along the shaft;
the silicone dilation balloon being constructed and adapted to dilate a lesion or plaque formation in the vein or artery;
an occlusion balloon introducer catheter, an occlusion balloon upon inflation being adapted to prevent back flow of emboli released from the dilation of the lesion or plaque;
inflation and deflation means for the dilation balloon; and
, means for inflation and deflation of the dilation and occlusion balloons, and for removal of released emboli. - View Dependent Claims (4, 5, 6, 7)
