Abstract
An apparatus includes a hub including a front port, a side port, and a back port including a hemostasis valve. The apparatus further includes a sheath extending from the hemostasis valve through the front port and shaped to define one or more lateral openings within the hub. The sheath is configured for insertion into a blood vessel such that, subsequently to the insertion, a rate of flow of blood between the side port and the blood vessel via the lateral openings is controllable using an instrument passing through the hemostasis valve and into the sheath such that the instrument closes at least a portion of the lateral openings. Other embodiments are also described.
Claims22
An apparatus, comprising:
- a hub comprising a front port, a side port, and a back port comprising a hemostasis valve;
- a sheath extending from the hemostasis valve through the front port and shaped to define one or more lateral openings within the hub,
- the sheath being configured for insertion into a blood vessel;
- and
- an instrument configured to reduce a rate of flow of blood between the side port and the blood vessel via the lateral openings without stopping the flow, subsequently to the insertion, by passing through the hemostasis valve and into the sheath such that the instrument closes at least a portion of the lateral openings.
A method, comprising:
- inserting a sheath, which extends from a hemostasis valve at a back port of a hub through a front port of the hub, into a blood vessel, the sheath being shaped to define one or more lateral openings within the hub;
- and
- subsequently to inserting the sheath, passing an instrument through the hemostasis valve and into the sheath, and using the instrument to close at least a portion of the lateral openings so as to control a rate of flow of blood between a side port of the hub and the blood vessel via the lateral openings.
