Abstract
Hemostasis valve devices and methods of use are disclosed. The hemostasis valve devices include a body member, a side-arm, a valve member, and a valve cap. The body member includes a body bore extending therethrough. The body bore includes a proximal bore portion in fluid communication a side-arm bore. In one embodiment, a fluid flow insert is disposed within the body bore in fluid communication with the side-arm bore and the proximal bore portion to direct flushing or priming fluid injected through the fluid flow insert into the proximal bore portion in a circular, spiral, or swirling flow path to remove entrapped air bubbles from the proximal bore portion.
Claims19
A hemostasis valve device, comprising:
- a body member comprising a body bore extending therethrough, wherein the body bore comprises a distal bore portion and a proximal bore portion;
- a side-arm extending radially outward from the body member and comprising a side-arm bore extending therethrough and in fluid communication with the proximal bore portion;
- and
- a valve member disposed within the body bore proximally of the side-arm and configured to selectively restrict fluid flow through the body bore,
- wherein the proximal bore portion comprises a first fluid flow path configured to flush air bubbles from the proximal bore portion.
A hemostasis valve device, comprising:
- a body member comprising a body bore extending through the body member, wherein the body bore comprises a distal bore portion and a proximal bore portion;
- a side-arm extending radially outward from the body member and comprising a side-arm bore extending through the side-arm and in fluid communication with the body bore;
- a valve member disposed within the body bore proximally of the proximal bore portion and configured to selectively restrict fluid flow through the body bore;
- and
- a fluid flow insert co-axially disposed within the body bore distally of the valve member,
- wherein the fluid flow insert is configured to direct a fluid flowing within the proximal bore portion in a circular flow path to flush air bubbles from the proximal bore portion.
A method of removing air bubbles from a medical device, comprising:
- injecting fluid through a side-arm bore of the medical device into a proximal body bore portion of the medical device,
- wherein the proximal body bore portion includes a circular, spiral, or swirling shape flow path.
