20130150789 | IMMOBILIZING OBJECTS IN THE BODY - Stabilizing an object in the body of a patient involves the injection of a lower critical solution temperature (LCST) material or other flowable material into the body of the patient so that the material contacts the object. The LCST material or other flowable material then forms a gel in the body such that the object is contained at least partially within the gel and thereby stabilized by the gel such that the object can then be easily fragmented within the body and/or retrieved from the body. | 06-13-2013 |

20140257458 | EXPANDABLE STENT DELIVERY SYSTEM WITH OUTER SHEATH - According to aspects described herein, there is disclosed an improved hot balloon catheter delivery system for shape memory tubular stents. An outer sheath is provided on the delivery system that facilitates stent placement on a balloon during delivery through an endoscope. In one embodiment, the stent may be positioned between radiopaque markers/electrodes and the balloon may be heated. The stent may be prevented from moving proximally relative to the catheter as the delivery system is tracked through the patient's anatomical passageways. The outer sheath may be positioned to ride over the proximal cone of the hot balloon catheter and abut the proximal end of the stent to facilitate proper alignment of the balloon for deployment. Upon deployment of the stent in an appropriate position, the sheath may be pulled away from the stent to expose the proximal cone of the balloon and thereby allow balloon and stent expansion. | 09-11-2014 |
