Delivery mechanism for balloons, drugs, stents and other physical/mechanical agents and method of use
First Claim
1. A catheter comprising:
- a. a body member having a lumen;
b. a balloon member disposed on the body member and communicating with the lumen;
c. a plurality of sleeve members disposed on the body member along a length of the body member, each sleeve member having a passageway and the sleeve members with gaps between them extending a substantial length of the body member, wherein at least one sleeve member extends through the balloon member; and
d. a sheath covering the plurality of sleeve members.

Abstract
A balloon catheter for use with a guidewire is disclosed. The catheter has a body with a balloon located thereon, preferably at the distal end. A lumen within the catheter body communicates with the interior of the balloon which can be inflated by known methods with saline solution. A series of sleeve members of predetermined lengths and sizes are coupled to and positioned along the length of the catheter body. One or more of the sleeve members can span the length of the balloon. Each sleeve member has a passageway and both an exit and entry port so that the guidewire can pass therethrough. Instead of a balloon, the catheter can include a device member that forms a chamber which can store medicine until discharged at the desired site within the blood vessel. Apertures or pores on the catheter body allow for the perfusion of blood or the delivery of medicine to the site of the blood vessel. A method of operation is also disclosed.
