Components and methods for a catheter positioning system with a spreader and track
Embodiments include a spreader and a resealable delivery channel in a catheter positioning system configured to introduce a catheter into the resealable delivery channel. The spreader may have shapes configured to help users insert the spreader and a catheter into the resealable delivery channel and to retain the spreader and the catheter within the resealable delivery channel. The resealable delivery channel may be shaped to accommodate the spreader or catheter. The resealable delivery channel may include flexible plastic lips that are moveable to facilitate insertion of the spreader and a catheter into the resealable delivery channel.
1. A catheter positioning system, comprising:
a modular plate configured to receive a proximal portion of a catheter;
a sled member coupled to the modular plate;
a sled base configured to advance the sled member towards a patient;
a resealable delivery channel coupled to the sled base and configured to receive and guide the catheter along a length of the sled base, the resealable delivery channel comprising a channel portion having a slotted opening on top along the length of the channel portion and flexible lips extending toward one another and parallel to the channel portion along opposed sides of the channel portion; and
a spreader comprising a shaped tip configured to guide the catheter between the flexible lips and into the channel portion, wherein the flexible lips are configured to enable the shaped tip to be inserted into the channel portion by pressing the shaped tip between the flexible lips from above, through the slotted opening on top, and into the channel portion, wherein the shaped tip is wider than a more proximal portion of the spreader such that, while the flexible lips engage opposed sides of the more proximal portion of the spreader, engagement of an underside of the flexible lips with a proximal portion of the shaped tip resists an inadvertent removal of the shaped tip from the channel portion.
2. The catheter positioning system of claim 1 , wherein the spreader comprises a rotatable tip portion distal to an attachment portion, wherein the rotatable tip portion freely rotates relative to the attachment portion.
3. The catheter positioning system of claim 1 , wherein the shaped tip comprises a bulb-shaped tip portion.
4. The catheter positioning system of claim 1 , wherein the shaped tip comprises a flanged tip portion.
5. The catheter positioning system of claim 1 , wherein the resealable delivery channel has a cross-sectional shape that conforms to a shape of the shaped tip of the spreader so as to guide the shaped tip within the channel portion.
6. The catheter positioning system of claim 1 , wherein an outer side of the flexible lips are configured to slant toward a bottom of the channel portion.
7. The catheter positioning system of claim 1 , wherein the flexible lips are attached to the resealable delivery channel by a rotatable joint.
8. The catheter positioning system of claim 7 , wherein the rotatable joint comprises a hinge.
9. The catheter positioning system of claim 1 , wherein the channel portion includes a hinge enabling the resealable delivery channel to be opened to receive the spreader.
10. The catheter positioning system of claim 1 , wherein the flexible lips are configured to include an entry hole with a wider opening than the slotted opening for insertion of the shaped tip into the channel portion.
11. The catheter positioning system of claim 1 , wherein the flexible lips are configured to form at least a partial seal around the spreader, wherein the at least the partial seal is movable with the spreader along the length of the sled base.
12. The catheter positioning system of claim 1 , wherein the flexible lips are configured to form a full seal around the spreader, wherein the full seal is movable with the spreader along the length of the sled base.
