Catheter with imaging assembly with placement aid and related methods therefor
View Patent ↗A feeding tube assembly having a feeding tube, an imaging assembly having a rigid axis and a bending axis transversely oriented relative to the rigid axis is disclosed. The imaging assembly can be preferentially deformable along the bending axis relative to the rigid axis. A marking disposed on at least one of the imaging assembly and the feeding tube can provide an indication of the bending axis. A packaging comprising a curvilinear cavity and a circular cavity can respectively contain the imaging assembly and the feeding tube, in a coiled configuration, which induces the feeding tube assembly into a pre-set, arcuate shape.
1. A method of providing a feeding tube assembly having a feeding passage and a feeding outlet for delivering enteral feeding liquid, the method comprising:
providing a feeding tube having an imaging assembly secured to the feeding tube proximate the feeding outlet of the feeding tube, the imaging assembly having a rigid axis and a bending axis that is transversely oriented relative to the rigid axis, wherein the imaging assembly is preferentially deformable along the bending axis relative to the rigid axis;
providing a container comprising a curvilinear cavity and a receiving cavity; and
arcuately disposing at least a portion of the imaging assembly in the curvilinear cavity in conformation with the bending axis of the imaging assembly to pre-form a desired bend into the imaging assembly facilitating insertion of the feeding tube assembly into the subject, the curvilinear cavity setting the imaging assembly in a curvilinear shape for being inserted into the subject;
removing the imaging assembly from the curvilinear cavity, the imaging assembly retaining the bend formed by the curvilinear cavity; and
inserting the feeding tube assembly into the subject after removing the imaging assembly from the curvilinear cavity without further bending the imaging assembly prior to inserting the feeding tube assembly into the subject.
2. The method of claim 1 , further comprising coiling at least a portion of the feeding tube in a plurality of loops, each of the loops having a coiling direction at least partially coincident the bending axis; and disposing at least one of the loops in the receiving cavity.
3. The method of claim 1 , wherein the feeding tube assembly further comprises a marking disposed on the feeding tube, and wherein the marking is configured to provide an indication of the bending axis.
