Treatment fluids may be provided to the treatment area via a fluid lumen and fluid may be removed from the treatment area via the same fluid lumen or separate aspiration lumen. | 10-03-2013 |
20130345628 | NARROW PROFILE CATHETER WITH DEFORMATION-RESISTIVE GUIDEWIRE LUMEN - The present disclosure relates to a catheter having a longitudinal guidewire lumen defined by a first tube configured for an over-the-wire or rapid-exchange mode of operation, the wall of the first tube provided with an expansion member that is a sub-region of the wall of the first tube provided with an expandable material. An inflation lumen extending from the proximal end towards the distal end of the shaft is in fluidic contact with the expansion member, the member being configured to expand or contract responsive to pressure in the inflation lumen. The wall of the first tube may be formed from a helically coiled wire or helically braided wire having a helix angle of 60 degrees or more which tubing is resistive to radial pressure applied in the inflation lumen. | 12-26-2013 |
20140107573 | BALLOON ENCAPSULATED CATHETER TIP - This invention is generally related to catheters for insertion into a body cavity, duct or vessel, and more particularly to a tip or plug for a catheter. The catheter tip is constructed and arranged to form a seal on the end portion of the catheter tube, while a sleeve secured or formed integrally to the tip cooperates with the catheter tube to form a first balloon that encapsulates the tip of the catheter and a second balloon that positions the catheter within the body cavity, duct or vessel. | 04-17-2014 |
20140180207 | VARIABLE LENGTH CATHETER FOR DRUG DELIVERY - A catheter system for localized delivery of a therapeutic or diagnostic agent within a vessel is provided. The system provides for adjustability of the length of the treatment area and for reducing of pressure within the treatment area. The catheter system includes an inner elongated element, an outer elongated element positioned coaxially with respect to the inner elongated element, a blood-release element at a distal end of the inner elongated element and a supply elongated element coaxial to the outer elongated element. A proximal occlusion element is positioned at the distal end of the outer elongated element, proximal to an outlet port. A distal occlusion element is positioned at a distal end of the inner elongated element. The distal end of the inner elongated element is distal to and movable with respect to the outer elongated element distal end. | 06-26-2014 |
20140336574 | DOUBLE BALLOON CATHETER - A catheter including a plurality of balloons extending from the outer surface of the catheter that when inflated create a seal between the catheter and the patient's thereby eliminating leakage of fluids from around catheter during the procedure. | 11-13-2014 |
20140378896 | BALLOON FOR TREATMENT OF STENOSIS AND METHOD FOR MANUFACTURING THE BALLOON - The present invention relates to a balloon ( | 12-25-2014 |
20150088062 | BIRTH TISSUE MATERIAL AND METHOD OF PREPARATION - A catheter for recovering amniotic fluid is provided. The catheter includes a flexible tube encompassing a first and second lumen. The first lumen includes a cannulated trocar head at the distal end capable of passing through an amnion and chorion membrane. A first balloon is positioned on the second lumen and is capable of inflating on the distal side of a chorion membrane. A second balloon is positioned on the second lumen and capable of inflating on the proximal side of an amniotic membrane. | 03-26-2015 |
20150289880 | SINGLE ACCESS FLOW-REVERSAL CATHETER DEVICES AND METHODS - Embodiments herein include devices and methods directed toward creating reverse flow within a vessel and thereby providing protection against embolic debris. Embodiments comprise a catheter and a plurality of occluders that are expandable and adjustable within a lumen to create low-pressure areas that reroute blood flow and embolic debris therein. | 10-15-2015 |
20150297201 | FISTULA MANAGEMENT DEVICE AND METHOD - A fistula management device for preventing enteric contents from leaking out of a bowel via a fistula opening in the bowel. The device comprises a tubular body that defines a main fluidic passageway extending from a first axial end to a second axial end of the tubular body. Inflatable cuffs are located at each of the first and second axial ends of the tubular body for creating a fluid seal between the first and second axial ends of the tubular body and inner walls of a bowel. | 10-22-2015 |
