Abstract
Occluding guidewires to access bodily lumen of a patient are disclosed. The occluding guidewires include a slotted tube and a balloon secured to a distal end of the slotted tube. The slotted tube includes a plurality of slots. The slots are in fluid communication with a lumen defined by the slotted tube. The balloon is secured about the slotted tube over one or more slots to permit inflation media to be communicated through one or more slots from the lumen into the inflation chamber of the balloon. The occluding guidewire may also include a proximal tube. A proximal lumen of the proximal tube is in communication with the lumen of the slotted tube. The occluding guidewire may be configured with a relatively small diameter using aspects of the present inventions.
Claims8
An occluding guidewire for accessing a bodily lumen of a patient, comprising:
- a slotted tube having an outer surface and an inner surface, the inner surface defining a lumen extending between a first end and a second end of the slotted tube, the slotted tube further defining a plurality of slots extending between the outer surface of the slotted tube and the inner surface at a distal portion of the slotted tube to increase the flexibility of the distal portion of the slotted tube;
- and
- a balloon having a first end and a second end and defining an inflation chamber, the balloon secured over the distal portion of the slotted tube with the inflation chamber in fluid communication with at least one of the plurality of slots.
