Abstract
Devices and methods for delivering therapeutic agents use a movable sheath member to deliver a therapeutic agent with little or no shear stress. The delivery device may include an outer body being configured to move away from a distal end of the delivery device. The movable sheath member may have a first section and a second section opposing the first section, the second section being configured to hold the therapeutic agent. The movable sheath may be configured to deliver the therapeutic agent by increasing the first section by moving the outer body away from the distal end.
Claims20
A delivery device for delivering a therapeutic agent from a distal end, comprising:
- an outer body being configured to move away from the distal end;
- and
- a movable sheath having a surface that includes a first section and a second section,
- wherein:
- the first section overlaps a portion of the second section;
- the second section surrounds an inner cavity configured to hold a therapeutic agent;
- and
- the movable sheath is configured to deliver the therapeutic agent by increasing the first section by moving the outer body away from the distal end.
A delivery device for delivering a therapeutic agent from a distal end, comprising:
- a push rod that is configured to move toward the distal end;
- an outer body that is configured to move away from the distal end;
- and
- a movable sheath that includes a first section and a second section that opposes a portion of the first section, the second section surrounding an inner cavity configured to hold and deliver the therapeutic agent,
- wherein the outer body is concentrically arranged about the second section.
A delivery device for delivering a therapeutic agent, comprising:
- a movable sheath having a surface, the surface includes a first section and a second section that overlaps a portion of the first section, the second section surrounding an inner cavity configured to hold and deliver the therapeutic agent;
- a fixed rod;
- and
- an outer body concentrically arranged about a portion of the movable sheath and the fixed rod,
- wherein the outer body is configured to move toward the fixed rod.
