Abstract
A dilation catheter system comprises a guide member, a dilation catheter, and an image sensor. The guide member includes a shaft comprising a distal end and a proximal end. The shaft further defines a longitudinal axis. The dilation catheter is movable relative to the guide catheter member and comprises an expandable dilator. The expandable dilator is sized to fit within one or both of a Eustachian tube or a passageway associated with a paranasal sinus. The image sensor is configured to provide visualization within anatomy of a patient. The image sensor is integral with the guide member.
Claims18
A dilation catheter system, wherein the dilation catheter system comprises:
- (a) a guide member, wherein the guide member includes a shaft comprising a distal end and a proximal end, wherein the shaft defines a longitudinal axis;
- (b) a dilation catheter movable relative to the guide member, wherein the dilation catheter comprises an expandable dilator, wherein the expandable dilator is sized to fit within one or both of a Eustachian tube or a passageway associated with a paranasal sinus;
- and
- (c) a visualization assembly comprising an image sensor, wherein the image sensor is configured to provide visualization within anatomy of a patient, wherein the visualization assembly is integral with the guide member and extends from the guide member at a location that is proximate to the distal end of the shaft such that the visualization assembly is unitarily secured at a fixed orientation relative to the distal end of the shaft to provide a field of view that is fixed relative to the distal end of the shaft.
A dilation catheter system, wherein the dilation catheter system comprises:
- (a) a guide member, wherein the guide member includes a shaft comprising a distal end and a proximal end, wherein the shaft defines a lumen extending along a longitudinal axis between the distal and proximal end, wherein the shaft is formed of a stiff material;
- (b) a dilation catheter movable within the lumen, wherein the dilation catheter includes an expandable dilator sized to fit within a passageway associated with a paranasal sinus;
- and
- (c) an imaging assembly integrated with the distal end of the shaft, wherein the imaging assembly comprises:
- (i) an image sensor,
- (ii) a rigid shaft containing the image sensor, and
- (iii) a light feature configured to provide illumination;
- wherein a proximal portion of the rigid shaft of the imaging assembly is unitarily attached to an exterior of a distal portion of the shaft of the guide member such that the rigid shaft of the imaging assembly is fixed at an orientation that is parallel to the longitudinal axis.
