Abstract
An implant can include a support component, a cover component, and a valve component. The valve component can be operable to permit flow through the implant. The implant can be delivered on a catheter, with one of the ends of the implant being selectively expanded to permit temporary occlusion of a vessel while delivering a material through the valve component to a downstream target region. The other end of the implant can thereafter be released such that the implant occludes the vessel, or the implant can be removed from the vessel entirely.
Claims26
A material delivery device, comprising:
- an expandable support member having a lumen and an outflow end, the support member being configured to expand from a collapsed configuration to an expanded configuration for placement in a body lumen;
- a cover component, extending along the support member, defining an aperture;
- and
- a valve component coupled to the cover component and disposed at the outflow end, the valve component permitting outflow of a material through the aperture and restricting backflow of the material into the aperture.
A method of delivering a material to a target region of a body lumen, comprising:
- advancing an implant to the target region, the implant having first and second sections engaged with a catheter at respective first and second engagement points;
- releasing the implant first section from engagement with the catheter at the first engagement point;
- permitting the implant first section to expand against a lumen wall at the target region such that the lumen becomes at least substantially occluded;
- and
- injecting a material through a portion of the implant.
A method of delivering a material to a target region of a body lumen, comprising:
- contacting a first occlusive implant, deployed within the lumen upstream of the target region, to remove the occlusion and permit flow through the first implant, thereby restoring flow through the lumen to the target region;
- and
- after contacting the first implant, injecting a material into the lumen such that the material passes through the first implant to the target region.
