A microcatheter for delivering embolic agent to a vascular site is provided. The microcatheter has a biocompatible or biocompatible and biodegradable tip which can be detachably engaged to the microcatheter body by a thermoplastic sleeve. Once the embolic agent is delivered to the desired vascular site, the tip of the microcatheter is often entrapped within the mass of the liquid embolic fluid. Using the microcatheter, the clinician can retract the microcatheter at a predetermined retraction force thereby disengaging the tip from the microcatheter body allowing for easier removal of the microcatheter.

A tissue tunneling device is configured to be delivered within the body. The tunneling device includes a shaft with a blunt distal end to prevent coring or other damage to tissue during the delivery of the tunneling device. In some arrangements, the shaft includes one or more lumen, through which medication or another fluid may be administered. An anesthetic or other pain relieving medication may be delivered through the lumen to lessen the discomfort of delivering the tunneling device to the desired anatomical site. The shaft may also include a retractable needle for facilitating the advancement of the tunneling device through skin or other tissue. The shaft may also be provided with an outer sheath, which may be left within the anatomy after the tunneling device has been removed. The shaft may be malleable for custom-shaping the tunneling device prior to and/or during delivery.

A catheter having features configured to provide a substantially uniform flow rate of a fluid exiting the catheter and also exhibits anti-microbial properties. The uniform flow rate features may include one or more of a flow restricting membrane or flow restricting component within an infusion section of the catheter. In other arrangements, exit holes defining the infusion section of the catheter may be configured to provide the desired uniform flow rate over the length of the infusion section. Furthermore, the catheter also includes anti-microbial properties to inhibit the growth of microbes on or within the catheter and, preferably, to inhibit microbe growth in an anatomical region surrounding the catheter. The desired anti-microbial properties may be provided by an anti-microbial layer, anti-microbial materials dispersed within the material from which components of the catheters are constructed, or a combination of anti-microbial layers and embedded anti-microbial materials. In some arrangements, one or more portions of the catheter may be bio-absorbable.

Anti-microbial catheter

Disclosed is a balloon catheter having an inflatable balloon having a radiation carrier such as a radiation delivery layer thereon. In one embodiment, the radiation delivery layer comprises one or more layers of metal foil, such as gold. The foil is irradiated, and the balloon is thereafter positioned at a treatment site in a vessel and expanded to bring the metal foil layer into close proximity with the vessel wall. In another embodiment, the radiation carrier is in the form of a dopant in the balloon material. Methods of using the balloon include radiation dosing a site following a balloon dilatation or other procedure, and simultaneously performing balloon angioplasty and radiation dosing.
