Abstract
Anti-buckling devices for supporting flexible elongated members are described herein. In one variation, an anti-buckling device includes a first coupler for coupling to a first device, a second coupler for coupling to a second device that is configured to position a catheter member, a first set of support members coupled between the first coupler and the second coupler, and a plurality of holders coupled to the support members, the holders configured for supporting the catheter member, wherein the first set of support members form a support frame that can be extended by moving the first and second couplers away from each other, and can be collapsed by moving the first and second couplers towards each other.
Claims25
An anti-buckling device, comprising:
- a first coupler for coupling to a first device;
- a second coupler for coupling to a second device, the second device configured to position a catheter member;
- a first set of support members coupled between the first coupler and the second coupler;
- a second set of support members disposed next to the first set of support members;
- a third set of support members disposed between the first and second sets of support members;
- and
- a plurality of holders coupled to the support members, the holders configured for supporting the catheter member, wherein the holders are each rotatably fixed with respect to each other;
- wherein the first set of support members form a support frame that can be extended by moving the first and second couplers away from each other, and can be collapsed by moving the first and second couplers towards each other.
A support device, comprising:
- a first set of support members arranged in a scissor-like configuration to form a support frame, wherein the support frame has a first end and a second end, and can be extended by moving the first and second ends away from each other, or collapsed by moving the first and second ends towards each other;
- a second set of support members disposed next to the first set of support members;
- a third set of support members disposed between the first and second sets of support members;
- and
- a plurality of holders coupled to support members, the holders configured for supporting a catheter member, wherein the holders are each rotatably fixed with respect to each other;
- wherein the holders are moveable relative to the catheter member supported by the holders, such that the holders are maintained at a substantially same distance from one another regardless of a distance between the first and second ends of the support frame.
An anti-buckling device, comprising:
- a first coupler for coupling to a first device;
- a second coupler for coupling to a second device, the second device configured to position a catheter member;
- a first set of support members coupled between the first coupler and the second coupler;
- a second set of support members that are disposed next to the first set of support members;
- a third set of support members that are disposed between the first and second sets of support members;
- a plurality of holders coupled to the support members, the holders configured for supporting the catheter member;
- wherein the first set of support members form a support frame that can be extended by moving the first and second couplers away from each other, and can be collapsed by moving the first and second couplers towards each other.
