An assembly for redirecting light emitted by an end-emitting optical fiber into an inner lumen of a body is provided. According to one implementation, the body includes one or more surfaces disposed on or in the body onto which the light is configured to impinge when the end emitting optical fiber is activated, the one or more surfaces being configured to alter the trajectory of the light so that the light is directed to impinge on a light reflector of a cap removably attached to the body, the light reflector of the cap being configured to redirect the light distally into the inner lumen of the body.

The present disclosure provides an apparatus that includes a first catheter having a proximal end and a distal end. The apparatus also includes a first tubular housing having a proximal end and a distal end. The first tubular housing is coupled to the first catheter proximal to at least one first outlet. The apparatus also includes one or more pressure sensors coupled to the distal end of the first tubular housing. The apparatus also includes a second catheter having a proximal end and a distal end. The distal end of the second catheter is configured to be positioned substantially within a second tubular housing coupled to one or more of the first catheter and the first tubular housing, when the second catheter is in a first position.

In some examples, a catheter includes a hub assembly, an elongate member, and a plurality of support wires extending along a length of the elongate member. The plurality of support wires is configured to expand radially outward from the elongated body to help anchor a distal portion of the catheter within the vasculature the patient and provide a backup support to the elongate member, e.g., to reduce pushback on the catheter when a treatment device is advanced past the distal tip of the catheter.

A balloon guide catheter system including a balloon guide catheter having a catheter shaft that includes: (i) a main lumen; (ii) an inflation lumen; and (iii) an exhaust lumen. The terminating distal end of the inflation lumen and the terminating distal end of the exhaust lumen being in localized fluid communication with one another underneath the balloon while in a non-inflated state. A balloon is disposed about a distal region of an outer surface of the catheter shaft. The exhaust lumen is configured to purge the residual air in a proximal direction and out from a proximal region of the balloon guide catheter.

A balloon guide catheter having a sleeved inflation lumen secured with a wire wrap for improved inflation lumen kink protection and a welded balloon construction provides a robust and flexible catheter with an exceptionally large inner lumen relative to its outer profile and enables rapid and reliable balloon inflation and deflation in a highly deliverable and kink resistant catheter. Balloon guide catheters having multiple sleeved inflation lumens and proximal luers for utilizing the multiple inflation lumens are also provided.

A lead assembly includes a lead with a distal end and a proximal end. The lead includes a plurality of electrodes disposed at the distal end and a plurality of terminals disposed at the proximal end. The lead also defines at least one central lumen and a plurality of outer lumens. The central and outer lumens extend from the proximal end to the distal end such that the plurality of outer lumens extend laterally from the at least one central lumen. The lead further includes a plurality of conductive wires. Each conductive wire couples at least one of the plurality of electrodes electrically to at least one of the plurality of terminals. At least two conductive wires are disposed in each of the plurality of outer lumens.

According to one implementation a central venous catheter is provided that includes an end emitting optical fiber that is configured to end emit bacterial disinfecting light to disinfect a conduit located inside the hub, the conduit connecting the working lumen of an infusion shaft with a working lumen of a main shaft.

An apparatus and methods tissue restoration are provided. The apparatus may include a catheter shaft extending from a proximal end to a distal tip and a translucent first distal balloon positioned on a translucent distal segment of the catheter shaft proximal to the distal tip in fluid communication with a drug source via a first lumen, the first distal balloon may include first and second outer surfaces, and a patterned outer profile of first distal balloon formed by the first outer surface and the second outer surface. A second distal balloon positioned inside of and concentric with the first distal balloon. A first light fiber and a second light fiber each positioned in the catheter shaft and extending through the translucent distal segment. The drug source provides at least one drug to the first distal balloon via the first lumen.

A balloon catheter includes a one-piece extrusion having inner and outer tubular walls, where the inner tubular wall defines a wire guide lumen, and a clearance extending between the inner and outer tubular walls forms an inflation lumen. A balloon is attached to the outer tubular wall and to the inner tubular wall, such that the inflation lumen is in fluid communication with the balloon and the wire guide lumen extends through the balloon. A method of making the balloon catheter is also disclosed.

The invention comprises an indwelling medical device which is capable of delivering a therapeutic agent evenly along the length of the indwelling portion, including the outer wall, of the device.
