Publication number: 20110196507Abstract: A medical stent is sized for placement in a ureter. The stent includes a first section which includes a first material, defines a lumen, and includes a first coil completing at least one revolution. A second section of the stent includes a second material, defines a lumen, and includes a second coil completing at least one revolution. A third section defines a lumen and is located between the first and second sections. The third section includes a co-extrusion of the first and second materials. One of the first or second sections is harder than the other section.Type: ApplicationFiled: April 21, 2011Publication date: August 11, 2011Applicant: BOSTON SCIENTIFIC SCIMED, INC.Inventor: Ernest J.

Patent number: 5792105Abstract: An inflatable medical device for delivering fluid internally to a patient comprising a catheter having a fluid delivery lumen communicating between a fluid entry port at its proximal end and a fluid delivery port on an external wall of the catheter and a hollow, inflatable balloon having at least one fluid transmitting conduit disposed between inner and outer balloon walls. The fluid transmitting conduit receives fluid from the fluid delivery port of the catheter and is connected to at least one outlet on the outer balloon wall. The inner balloon wall extends axially beyond the proximal terminus of the outer balloon wall to form an inner sleeve for attaching the inner balloon wall to the catheter. An outer collar is attached at its distal end to the outer balloon wall and at its proximal end to the catheter at a point proximal to the fluid delivery port. The outer collar forms a conduit between the fluid delivery port and the proximal opening of the fluid transmitting conduit of the balloon.Type: GrantFiled: September 11, 1996Date of Patent: August 11, 1998Assignee: Boston Scientific CorporationInventors: Donna Lin, Ernest J.
