SINUS ILLUMINATION LIGHTWIRE DEVICE
First Claim
Patent Images
1. An illuminating guidewire device for use at a site within a patient'"'"'s body, the guidewire device comprising:
- an elongate flexible housing having a proximal end, a distal end configured to be placed at the site within a patient'"'"'s body, and a lumen extending through the housing from the proximal end to the distal end;
at least one illuminating fiber extending through the lumen of the housing; and
a connector coupled with the proximal end of the elongate housing and a proximal end of the at least one illuminating fiber, the connector including a sliding member attached to the elongate housing so that the proximal end of the housing can move longitudinally within the connector;
wherein the proximal end of the at least one illuminating fiber is fixedly attached to the connector and extends into the proximal end of the housing such that the housing can slide over the at least one fiber as it moves longitudinally within the connector.

Abstract
An illuminating wire medical device may include an elongate flexible housing and an illuminating fiber and a core wire extending through at least part of the housing, the core wire providing desired pushability and torquability. The illuminating device may further include a connector assembly cooperating with the illuminating fiber to accommodate changes in length and to absorb forces applied during use of the device.

13. An illuminating guidewire assembly, comprising:
-
a connector including a proximal portion, a distal portion and a sliding member disposed in the proximal portion; an elongate flexible body coupled with the sliding member and extending through and distally from the distal portion of the connector, the body having a lumen; an illuminating fiber fixedly attached to the connector and extending through the lumen of the elongate body; and a core wire disposed in the lumen of the elongate body, wherein the core wire is shorter than the elongate body, and wherein the core wire is disposed nearer a distal end of the elongate body than a proximal end of the elongate body. - View Dependent Claims (14, 15, 16, 17, 18)

23. A method for visually confirming the positioning of a distal end of a device placed within a patient, said method comprising:
-
inserting a distal end of an illuminating device into a patient, injecting a light activated drug through the illuminating device into the patient; emitting light from the distal end portion of the illuminating device; observing transillumination resulting from the light emitted from the distal end portion of the illuminating device that occurs on an external surface of the patient as enhanced by the light activated drug; and correlating the location of the observed transillumination on the external surface of the patient with an internal location of the patient that underlies the location of observed transillumination, to confirm positioning of the distal end of the illuminating device. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36)
