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.
Claims27
Apparatus, comprising:
- a hub comprising a front port, a side port, and a back port comprising a hemostasis valve;
- and
- 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 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.
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, controlling a rate of flow of blood between a side port of the hub and the blood vessel via the lateral openings, by passing an instrument through the hemostasis valve and into the sheath such that the instrument closes at least a portion of the lateral openings.
A kit for use with a hub including a front port, which is connected to a sheath, and a back port, which includes a hemostasis valve, the kit comprising:
- a tube;
- and
- an adapter configured to connect to the tube and configured for insertion through the hemostasis valve such that, subsequently to an insertion of the sheath into a blood vessel, blood flows between the blood vessel and the tube via the adapter.
Apparatus, comprising:
- a sheath;
- a hub, comprising a front port, which is connected to the sheath, and a back port comprising a hemostasis valve;
- an adapter passing through the hemostasis valve;
- and
- a tube connected to the adapter such that, subsequently to an insertion of the sheath into a blood vessel, blood flows between the blood vessel and the tube via the adapter.
A method, comprising:
- inserting an adapter, which is connected to a tube, through a hemostasis valve at a back port of a hub;
- and
- inserting a sheath, which is connected to a front port of the hub, into a blood vessel such that blood flows between the blood vessel and the tube via the adapter.
