A delivery catheter for delivery, then photo-activation of photo sensitive material has a photo-sensitive substance-delivery part and an activation part. The catheter delivers substances such as biomaterials to a target site, followed by illumination of the target using optics located at the distal tip of the catheter which are optically coupled to an extracorporeal light source. The light may be delivered by a single or multi-lumen needle, or a separate light guide passed over the catheter.

Reduced profile and enhanced flexibility delivery catheters for light activated agents

Devices for delivering drugs or other treatment agents locally to the vasculature of a mammal are disclosed. These devices have several related structures and are designed to deliver the drugs to facilitate rapid mixing with the blood flowing past the devices.

Method and apparatus for delivering an agent to a kidney

Methods for making devices include providing a tubular member to be formed into a device, placing a removable sacrificial block material in the lumen of the tubular member and laser cutting the tubular member. A tubular member made from nickel-titanium alloy can be tightly adhered to a sacrificial sleeve utilizing the phase changes associated with nickel-titanium. A mandrel which includes an enlarged diameter section causes the workpiece to expand slightly within its elastic deformation range to dislodge islands from the workpiece. Such a mandrel could be formed from a tubular member which has a central lumen that can be used to deliver a pressurized medium to 'blast' islands from the workpiece.

Methods for laser cutting tubing to make medical devices

The present invention relates to balloon catheters for treating a luminal system of a patient. Specifically, the invention relates to catheters having a flexible membrane positioned at a distal portion of the catheter, the flexible membrane retained in a substantially unexposed conformation prior to deployment. Preferably the flexible membrane is capable of delivering a therapeutic agent to a localized environment when deployed to an exposed conformation.

Substantially anhydrous electropolishing electrolyte solutions. The substantially anhydrous electropolishing electrolyte solutions described herein do not use water as a solvent; instead, such electropolishing electrolyte solutions use anhydrous alcohols and/or glycols as a solvent. For example, an electropolishing electrolyte solution, as described herein, may include an alcohol, at least one mineral acid, and phosphorous pentoxide ('PO'). Methods of electropolishing metal articles using such electropolishing electrolyte solutions are disclosed herein as well.

Electropolishing solution containing phosphorous pentoxide and methods of use thereof

A catheter for delivering an agent to an injection site in a wall of a patient's body lumen, with an elongated shaft having a needle-through lumen slidably containing a needle therein, and an expandable member on the distal shaft section which has a collapsed configuration and a radially expanded configuration. In the radially expanded configuration, the expandable member supports the shaft in a position spaced away from the body lumen wall, and the needle slidably exits the needle-through lumen in the extended configuration through the port spaced away from the body lumen wall as a portion of the expandable member maintains the position of the port section of the shaft in the body lumen. The expandable member typically has an open-walled, helical, or lobed configuration providing a perfusion path along the expandable member.

Determining stability of a catheter is described. A first signal originating from a first region of a patient is monitored and a second signal originating from a second region of the patient is monitored. First components from a recurring interval of the second signal are extracted, where the recurring interval is defined by the first signal. The first components are compared to determine a first similarity value of the first components over time. The first similarity value is compared to a threshold value to determine a stability evaluation for a source of the second signal.

Electrode data analysis to indicate catheter stability and/or needle penetration success

A catheter which allows the rotational orientation of the distal end of the catheter to be adjusted in discrete intervals as the physician rotates the proximal end of the catheter. The catheter is designed to intentionally induce whipping but to limit the amount of whipping to a desired rotational interval.

Catheter configured for incremental rotation

Delivery system for delivery of a medical device includes an inner member having a proximal section, a distal section and a longitudinal axis therebetween. The inner member has a first layer and a second layer wherein the first layer and the second layer are attached together at a first segment and a second segment. The second segment is spaced from the first segment along a length of the inner member and the first layer and the second layer are free of attachment between the first segment and the second segment. The inner member further includes at least two wires disposed along the length of the inner member between the first layer and the second layer. As disclosed, the at least two wires can include a first coil and a second coil moveable relative to each other between the first and second segments.

Agent delivery catheter having a radially expandable centering support members

An agent delivery catheter having two or more axially spaced balloons and an inflation bridge providing fluid communication between the two balloons. The catheter generally has a proximal balloon, a distal balloon, and a tube defining an inflation bridge lumen which is located in part within the inflatable interiors of the balloons, and which extends therebetween, and which has a proximal port within the proximal balloon interior and a distal port within the distal balloon interior to thereby provide for inflation of the distal balloon by placing the distal balloon interior in fluid communication with the proximal balloon interior of the shaft.
