Abstract
The present invention relates to a catheter apparatus with an anchoring device to stabilize the catheter tip when in use, such as when infusing, injecting, or delivering substances, devices or other catheters into a patient. The apparatus according to various embodiments deploys an anchoring device that stabilizes the catheter tip and enables adjustment of the blood flow during use.
Claims21
-20. (canceled)
A medical device for delivery of one or more of medicaments, agents, catheters, or devices into a body channel, the medical device comprising:
- an outer sheath having a distal end;
- an inner sheath having a distal end, the inner sheath being axially translatable and fitting within the outer sheath;
- and
- an expansile anchor mechanism deployable between collapsed and expanded configurations by axially translating the inner and other sheaths relative to one another,
- wherein the expansile anchor mechanism comprises a fluid permeable mesh configured to engage a wall of the body channel and exert a controlled axial force against the wall when in the expanded configuration,
- wherein the expansile anchor mechanism is configured to at least partially obstruct fluid flow in the body channel when in the expanded configuration within the body channel, and
- wherein the expansile anchor mechanism, when in the expanded configuration, comprises a channel therethrough, wherein the channel is in fluid communication with a lumen of the inner sheath and configured to deliver the one or more medicaments, agents, catheters, or devices into the body channel when the expansile anchor mechanism is in the expanded configuration.
A method of delivering of one or more of medicaments, agents, catheters, or devices into a body channel, the method comprising:
- advancing a medical device to a target site;
- expanding an expansile anchor mechanism of the medical device from a collapsed configuration to an expanded configuration at the target site, wherein expanding the expansile anchor mechanism comprises translating outer and inner sheaths of the medical device relative to one another to deploy the expansile anchor mechanism in the target site, and wherein the expansile anchor mechanism is configured to at least partially obstruct fluid flow in the body channel when in the expanded configuration within the body channel;
- exerting a controlled axial force against the wall of the body channel with the expansile anchor mechanism in the expanded configuration, wherein the expansile anchor mechanism comprises a fluid permeable mesh;
- and
- delivering one or more medicaments, agents, catheters, or devices into the body channel through a channel in the expansile anchor mechanism.
