| 20120123511 | PROSTHESIS DEPLOYMENT SYSTEM FOR VASCULAR REPAIR - A deployment system for vascular repair of a transected body vessel is provided. The system can include a prosthesis, an inner sheath, and an outer sheath. The inner sheath can be configured to selectively retain a first portion of the prosthesis in the compressed configuration, leaving a remaining portion of the prosthesis uncovered by the inner sheath. The outer sheath can be configured to retain the remaining portion of prosthesis in the compressed configuration and the first portion of the prosthesis within the inner sheath. The outer sheath is removable from the prosthesis to allow an expansion of the remaining portion of the prosthesis to the expanded configuration at a first opening in the transected vessel. The inner sheath is removable from the prosthesis first portion to allow an independent expansion of the first portion to the expanded configuration at a second opening in the transected vessel. | 05-17-2012 |

A second tubular member is alignable such that the proximal end communicates with an area exterior of the patient, and the distal end extends into the jejunum of the patient. A hub positioned in the stoma has a first opening communicating with the first tubular member, and a second opening communicating with the second tubular member. Respective closure members may be provided for selectively sealing the first and second openings. | 12-24-2009 |
| 20090221959 | ELONGATED MEDICAL APPARATUS WITH INFLATABLE TIP - An elongated medical apparatus suitable for insertion into a bodily passageway of a patient for carrying out a medical procedure. The elongated apparatus includes an elongated tubular body having a proximal portion and a distal portion, wherein the distal portion terminates at a distal end. The tubular body has a plurality of lumens extending therein. An inflatable balloon member is mounted at the distal end of the tubular body and extends in a distal direction therefrom. The balloon member is inflated by receiving an inflation fluid through one of the lumens. The presence of the balloon member at the leading end of the elongated apparatus reduces the risk of puncture and trauma upon insertion of the apparatus into the bodily passageway. | 09-03-2009 |
