Abstract
Catheter connectors and connector assemblies that are configured to reduce the likelihood of ESC cracks.
Claims26
A catheter connector, comprising:
- a support tube defining a longitudinal axis;
- and
- a barb, associated with the support tube, that defines a perimeter in a plane perpendicular to the longitudinal axis and includes at least one sharp edge that extends partially around the perimeter and at least one region without a sharp edge that extends partially around the perimeter and is longitudinally aligned with the sharp edge.
A connector for use with a catheter, the connector comprising:
- a support tube defining a longitudinal axis;
- and
- means, associated with the support tube, for creating different levels of stress with longitudinally aligned regions of the catheter when the catheter is positioned over the support tube.
A catheter connector, comprising:
- a support tube defining a longitudinal axis;
- and
- a barb associated with the support tube and defining a substantially circular cross-section in a plurality of longitudinally spaced planes oriented perpendicular to the longitudinal axis and a non-circular cross-section a plurality of longitudinally spaced planes oriented perpendicular to the longitudinal axis.
A catheter connector, comprising:
- a support tube defining a longitudinal axis;
- and
- a barb, associated with the support tube, defining an exterior surface shaped like a zone of a sphere with first and second circumferentially spaced indentations formed therein.
A connector for use with a catheter, the connector comprising:
- a support tube defining a longitudinal axis, a support tube perimeter and a free end;
- means for stretching a first portion of the catheter into a first shape having a first perimeter that is greater than the tube support perimeter;
- and
- means for stretching a second portion of the catheter, which is located between the free end and the first portion of the catheter, into a second shape, which is different than the first shape, having a second perimeter that is greater than the tube support perimeter and is greater than the first perimeter.
1 more element
A catheter connector, comprising:
- a support tube defining a longitudinal axis;
- and
- a barb associated with the support tube and including first and second barb members, the first barb member including an outer surface without sharp edges and defining an apex, and the second barb member defining a perimeter in a plane perpendicular to the longitudinal axis and including at least one sharp edge that is longitudinally spaced from the apex of the first barb member and extends at least partially around the perimeter.
