Abstract
Apparatus and methods for controlled arterial/venous access are provided. The apparatus and methods may include a lumen anastomosed to a bodily lumen. A lumen clamping means may utilize a clamp manipulator to effectively seal the tubing, and the manipulator may be operated by two fingers. A needle receptor may be utilized, and the receptor may utilize a compressible member to seal tightly against a needle inserted from outside the body, in order ensure secure placement into a channel. The channel may be in liquid communication with the tubing. The manipulator and the needle receptor may be palpable from outside the body.
Claims19
A subcutaneous vascular access device designed for repeated access to a native body vessel comprising:
- a lumen and a housing, said lumen extending between said housing located at a lumen proximal end and a lumen distal end configured to be attached to an anastomosis junction with a blood vessel, said anastomosis junction being located at the lumen distal end, wherein said lumen is configured to be in fluid communication with the native body vessel and said housing,
- wherein fluid flow through said lumen is selectively sealed by a clamp,
- wherein said housing comprises at least one funnel shaped needle receptor, a hollow spherical chamber, and at least one clamp actuator that is mechanically linked to said clamp and is arranged to selectively actuate said clamp,
- wherein said at least one funnel shaped needle receptor is selectively in fluid communication with said hollow spherical chamber and said at least one funnel shaped needle receptor is arranged coaxially on an axis that intersects said hollow spherical chamber at a point that is tangential to said hollow spherical chamber, and further, wherein said lumen is in fluid communication with said hollow spherical chamber.
A subcutaneous vascular access device designed to selectively provide fluid communication between a needle inserted from outside the body and a native bodily vessel within a body comprising:
- a lumen and a housing, said lumen extending between said housing located at a lumen proximal end and a lumen distal end configured to be attached to an anastomosis junction with a blood vessel, said anastomosis junction being located at the lumen distal end, wherein said lumen is configured to be in fluid communication with the native bodily vessel and said housing, wherein fluid flow through said lumen is selectively sealed by a clamp, with said clamp being arrangable adjacent and proximally locatable relative to said anastomosis junction, with said anastomosis junction being further arrangable to accept an anastomosis for affixing said lumen to the native bodily vessel;
- wherein said housing comprises at least one funnel shaped needle receptor, a hollow spherical chamber, a safety button, and at least one clamp actuator that is mechanically linked to said clamp through a lever system whereby said at least one clamp actuator is arranged to selectively actuate said clamp;
- wherein said at least one funnel shaped needle receptor is selectively in fluid communication with said hollow spherical chamber and said at least one funnel shaped needle receptor is arranged coaxially with an axis that intersects said hollow spherical chamber at a point that is tangential to said hollow spherical chamber, and further, wherein said lumen is in fluid communication with said hollow spherical chamber;
- and
- wherein said at least one clamp actuator further comprises at least one tab, wherein said at least one tab is connected to said lever system in a rotationally sliding arrangement.
