Abstract
A valve configured for a lumen of medical device is provided. The valve includes a valve body that may be elastically deformed from a first configuration to a second configuration. The valve body includes a lumen having a closed configuration and an open configuration. The lumen may be actuated from the closed configuration to the open configuration by elastically deforming the valve body from the first configuration to the second configuration. The valve body may include a portion configured to form a seal with an interior surface of a lumen of a medical device.
Claims16
An elongate medical device, comprising:
- a catheter comprising an elongate shaft extending between a proximal end and a distal end, the shaft comprising a shaft lumen there through;
- a valve body disposed within the shaft lumen, the valve body having a first segment and a second segment, the first segment integral with the second segment, wherein the first segment forms a seal with an inner surface of the shaft lumen, and wherein the second segment is elastically deformable from an elastically relaxed first configuration to a second configuration;
- a lumen extending through the valve body, the lumen in communication with the shaft lumen and having a first portion extending through the first segment and a second portion extending through the second segment, wherein the second portion is actuable between a closed configuration and an open configuration, wherein elastic deformation from the first configuration to the second configuration causes the second portion to actuate from the closed configuration to the open configuration, and wherein the elastic deformation from the first configuration to the second configuration is caused by an external force applied to an exterior surface of the catheter shaft, the external force being configured to cause simultaneous deformation of the catheter shaft and the valve body while maintaining the seal there between;
- and
- a hub disposed about the proximal end of the catheter shaft, the hub being configured to apply the external force to the exterior surface of the catheter shaft to cause simultaneous deformation of the catheter shaft and the valve body, wherein the hub is removable from the catheter shaft to reduce the profile of the elongate medical device.

An elongate medical device, comprising:
- a catheter comprising an elongate shaft extending between a proximal end and a distal end, the proximal end of the shaft being elastically deformable, the shaft comprising a shaft lumen extending there through;
- an elastically deformable valve body disposed within the shaft lumen at the proximal end of the shaft, the valve body extending from a proximal end to a distal end along a longitudinal axis;
- a slit extending through at least a portion of the valve body along the longitudinal axis, the valve body having a first radial axis corresponding to the slit, wherein compression of the valve body along the first radial axis causes elastic deformation of the valve body and causes the slit to open to provide a path of fluid communication through the valve body from the proximal end to the distal end;
- and
- a detachable hub operably coupled to the proximal end of the catheter shaft, the detachable hub comprising a means for applying an external force to an exterior surface of the proximal end of the catheter shaft so as to cause simultaneous deformation of the catheter shaft and the valve body along the first radial axis.

A balloon catheter assembly, comprising:
- a balloon catheter having a proximal end, a distal end, a first lumen extending from the proximal end to the distal end, and a balloon disposed on the distal end and in fluid communication with the first lumen;
- a valve comprising a valve body disposed within the first lumen at the proximal end of the balloon catheter, the valve body having a collapsed second lumen extending therethrough, wherein the second lumen can be opened by elastically deforming the valve body from a first configuration to a second configuration;
- and
- a detachable hub disposed about the proximal end of the balloon catheter and comprising a seal capable of elastically deforming the valve body by applying an external force to an exterior surface of the proximal end of the balloon catheter to open the second lumen.
