Abstract
Medical delivery devices, such as catheters, and their methods of use and manufacture. The medical delivery devices are adapted to facilitate the delivery of an agent into a patient. The medical delivery devices may have one or more deformable lumens, each of which has a collapsed configuration and an open configuration. The medical delivery devices may include one or more agent delivery ports, any one of which may be proximal or distal to an expandable device, such as a balloon.
Claims1
A catheter for delivering an agent into a patient, comprising:
- an outer shaft comprising one or more agent delivery ports;
- a guidewire channel within the outer shaft, the guidewire channel defining a guidewire lumen sized and configured to receive a guidewire therein;
- a balloon inflation channel within the outer shaft, the balloon inflation channel defining a balloon inflation lumen in fluid communication with an internal volume of an inflatable balloon;
- and
- an agent delivery lumen defined by an inner surface of the outer shaft, an outer surface of the guidewire channel and an outer surface of the balloon inflation channel,
- the agent delivery lumen in communication with the one or more agent delivery ports, and the one or more agent delivery ports proximal to at least a portion of the inflatable balloon, and
- wherein a proximal portion of the guidewire channel is deformable between an open guidewire configuration and a collapsed, agent-delivery configuration.
