Apparatus and method for permitting introduction and withdrawal of a catheter
First Claim
1. An apparatus for moving a catheter, having a proximal end, a distal end, and at least one lumen, along a guidewire, having a proximal terminus and a distal terminus, the apparatus comprising:
- a reel, having an axis of rotation, and having a rim, the rim having a first groove for carrying a portion of the guidewire that lies outside the catheter and a second groove for carrying a portion of the catheter, wherein a portion of the guidewire lies within the portion of the catheter carried in the second groove; and
a housing for holding the reel, the housing having an exit through which the catheter may pass.

Abstract
A catheter reel apparatus facilitating one-person, single-handed control of catheter movement along a guidewire is provided in an embodiment. In a preferred embodiment, the reel has two grooves of different dimensions. The first groove is sized to carry a portion of the guidewire not within a catheter lumen while the second groove is sized to carry a portion of the catheter, which has the guidewire inserted in the lumen. As the reel is rotated, the proximal end of the catheter is deployed from the device through an exit provided by a housing. Continued rotation pays out the desired length of catheter and the catheter is guided, without guidewire moving into or out of the housing, to a desired location. When the catheter is to be withdrawn, the reel is rotated in the opposite sense to catheter deployment.
