Abstract
A method includes disposing a lumen-defining device within a portion of a vein of a patient. A support member is inserted into a lumen of the lumen-defining device and advanced through at least a portion of the lumen of the lumen-defining device. At least a portion of the lumen-defining device is supported via the support member such that the support member limits complete occlusion of the lumen in response to a force exerted on the lumen-defining device. A volume of bodily fluid is withdrawn from the patient via the lumen-defining device when the support member is disposed in the lumen-defining device.
Claims19
A method, comprising:
- disposing a lumen-defining device within a portion of a vein of a patient;
- inserting a support member into a lumen of the lumen-defining device, wherein the lumen-defining device is a catheter having an inner diameter and the support member is a filament having an outer diameter less than the inner diameter;
- advancing the support member through at least a portion of the lumen of the lumen-defining device;
- supporting, via the support member, at least the portion of the lumen-defining device such that the support member is configured to limit complete occlusion of the lumen in response to a force exerted on the lumen-defining device;
- and
- withdrawing a volume of bodily fluid from the patient via the lumen-defining device when the support member is disposed in the lumen-defining device.
A method, comprising:
- establishing fluid communication between a lumen-defining device and a fluid source;
- coupling a support member to a hub of the lumen-defining device such that a portion of the support member is disposed in a lumen of the lumen-defining device, wherein the lumen-defining device is a catheter having an inner diameter and the support member is a filament having an outer diameter less than the inner diameter;
- supporting, via the support member, at least a portion of the lumen-defining device such that the support member is configured to limit complete occlusion of the lumen in response to a force exerted on the lumen-defining device;
- coupling a fluid transfer device to the hub of the lumen-defining device;
- and
- withdrawing a volume of fluid from the fluid source into the fluid transfer device via the lumen-defining device when the support member is disposed in the lumen-defining device.
A method, comprising:
- disposing a lumen-defining device within a portion of a vein;
- inserting a support member into a lumen of the lumen-defining device;
- advancing the support member through the lumen of the lumen-defining device to a distal position such that at least a portion of the support member is disposed within the vein and distal to the lumen-defining device;
- transitioning the support member from a first configuration to a second configuration after the support member is placed in the distal position;
- and
- transitioning an anatomic valve within the vein from a substantially closed state to a substantially open state when the support member is in the distal position and in the second configuration,
- wherein a central axis extending through a distal end surface of the support member extends in a first direction when the support member is in the first configuration,
- the transitioning of the support member from the first configuration to the second configuration is such that the central axis extends in a second direction different from the first direction when the support member is in the second configuration.
