Abstract:
1. A catheter assembly comprising: a control handle; an inner catheter member having a proximal end and a distal end and further including a distal mounting portion adapted to have a medical device mounted thereon, the proximal end attached to the control handle, and a guide wire receiving member having a proximal end and a distal end and being configured for receiving a guide wire, the proximal end of the guide wire receiving member being spaced apart from the proximal end of the inner catheter member, the guide wire receiving member further including an opening at the proximal end and an opening at the distal end and a lumen extending between these openings formed on the distal and proximal ends of the guide wire receiving member; and an outer catheter member co-axially disposed over the inner catheter member and dimensioned for relative axial movement relative to each other, the outer catheter member being comprised of multiple portions, wherein the outer catheter member includes a distal portion having a proximal end and a distal end, the distal portion being adapted to at least partially cover the medical device, the distal portion having an inner surface configured to directly contact the medical device, an intermediate portion having a distal end and a proximal end, the distal end of the intermediate portion coupled to the proximal end of the distal portion, and a proximal outer member having a proximal end and a distal end, the proximal end of the proximal outer member being coupled to the control handle and the distal end of the proximal outer portion being coupled to the proximal end of the intermediate portion, wherein the proximal end of the intermediate portion has an outer diameter and the distal end of the proximal outer member has an outer diameter, the outer diameter of the proximal end of the intermediate portion being larger than the outer diameter of the distal end of the proximal outer member to allow for a guide wire to exit the proximal end of the guide wire receiving member through an opening formed at the proximal end of the intermediate portion of the outer catheter member, wherein a length of the proximal portion extends into the opening of the proximal end of the intermediate portion to create a passage between the proximal portion and the intermediate portion through which the guide wire is configured to extend.
