DRAINAGE OR FEEDING CATHETER ASSEMBLY

摘要

Catheter assemblies, kits and methods allowing for the drainage or administration of fluid or small particles are disclosed. A catheter assembly can include a shaft with a lumen, an expandable retention member, an elongate actuation member and a locking mechanism. The expandable retention member can be positioned at a shaft distal end portion and can include one or more filaments forming a plurality of drainage or administration interstices of variable or uniform size. The elongate actuation member can include an actuation member distal end, directly or indirectly engaged with the expandable retention member, and an actuation member proximal end. Movement of the actuation member proximal end relative to a proximal end of the shaft can cause the expandable retention member to change from a lower-profile configuration to a higher-profile configuration. A moved position of the elongate actuation member can be secured by rotating, sliding or otherwise manipulating the locking mechanism.

1. A catheter assembly, comprising:
a shaft having a lumen, extending from a shaft proximal end portion to a shaft distal end portion; an expandable retention member, positioned at the shaft distal end portion, including one or more filaments forming a plurality of drainage or administration interstices; an elongate actuation member, extending from an actuation member proximal end to an actuation member distal end, the actuation member distal end operably engaged with the expandable retention member; and a locking mechanism, positioned at the shaft proximal end portion, configured to move between a first position, in which the elongate actuation member is movable relative to the shaft, and a second position, in which the elongate actuation member is locked relative to the shaft.
