BALLOON CATHETER ASSEMBLY

摘要

A dilation catheter comprises a handle, a guidewire, a dilation catheter, a guidewire movement mechanism, and dilation catheter movement actuator. The guidewire movement mechanism is configured to translate to thereby cause translation of the guidewire relative to the handle. The dilation catheter movement mechanism is configured to translate to thereby cause translation of the dilation catheter relative to the handle. The guidewire movement mechanism also includes a rotation mechanism configured to impart rotation upon the guidewire. The rotation mechanism may include features configured to limit the amount that the guidewire may rotate. The rotation mechanism may also include features configured to convert linear movement of an actuator into rotational movement of the guidewire. The dilation catheter may include features configured to provide for side entry of the guidewire into the dilation catheter.

主权项

1. A dilation catheter system, wherein the dilation catheter system comprises:
(a) a body, wherein the body comprises a distal end and a proximal end, wherein the body defines a longitudinal axis; (b) a guidewire; (c) a dilation catheter, wherein the dilation catheter comprises an expandable dilator; and (d) a guidewire movement mechanism, wherein the guidewire movement mechanism is configured to translate relative to the body to thereby provide longitudinal movement to the guidewire, wherein the guidewire movement mechanism further comprises a guidewire rotation feature, wherein the guidewire rotation feature comprises at least one translatable member, wherein the translatable member is configured to translate linearly to thereby cause rotation of the guidewire.
