Abstract
A catheter includes an elongated body and an expandable member configured to expand radially outward away from the elongated body from a collapsed configuration to an expanded configuration. The catheter further includes a retainer configured to overlap an end of the expandable member to hold the expandable member in the collapsed configuration. The expandable member may be configured to engage with a vessel wall when the expandable member is in the expanded configuration. The vessel may curve and the expandable member may be configured to deflect a portion of the elongated body distal to the expandable member when the expandable member is engaged with the vessel wall to better conform the shape of the elongated body to the curved portion of the vessel.
Claims27
A catheter comprising:
- an elongated body;
- an expandable member extending from a first end to a second end, the first end of the expandable member being mechanically connected to the elongated body, wherein the expandable member is configured to expand radially outward away from the elongated body from a collapsed configuration to an expanded configuration;
- and
- a retainer configured to overlap the second end of the expandable member to hold the expandable member in the collapsed configuration.
A catheter comprising:
- an elongated body;
- an expandable member extending from a first end to a second end, the first end of the expandable member being mechanically connected to the elongated body and the second end of the expandable member being unconnected to the elongated body, wherein the expandable member is configured to expand radially outward away from the elongated body from a collapsed configuration to an expanded configuration, and wherein the expandable member defines a funnel in the expanded configuration;
- and
- a retainer configured to overlap only the second end to hold the expandable member in the collapsed configuration, wherein the retainer is configured to release the second end of the expandable member to enable the expandable member to expand from the collapsed configuration to the expanded configuration.
