Various embodiments disclosed relate to drug-coated balloon catheters for treating, preventing, or reducing the recurrence of a stricture and/or cancer, or for treating benign prostatic hyperplasia (BPH), in a non-vascular body lumen and methods of using the same. A drug-coated balloon catheter for delivering a therapeutic agent to a target site of a body lumen stricture includes an elongated balloon having a main diameter. The balloon catheter includes a coating layer overlying an exterior surface of the balloon. The coating layer includes one or more water-soluble additives and an initial drug load of a therapeutic agent. In some embodiments, the balloon catheter includes a length-control mechanism which stretches and elongates the balloon when it is in a deflated state, giving the balloon a smaller cross-sectional deflated profile for tracking through the body lumen and for removal after treatment.

Methods of making sleeved and packaged hydrophilic urinary catheters (10).

The present invention is pursuant to the fields of Pharmacy and Medicine. More specifically, the invention provides an intraurethral dosage form of liquid or gel medication for men or women. In one embodiment, an applicator provides advantages in its use, facilitating the application of pharmaceutical compositions directly into the urethral channel and providing fast local effect without substantial risk. The invention provides a dosage form and route of administration for several medications, being particularly useful for the application of anti-inflammatory and/or anesthetic medications, for the treatment of female cystitis, for modulating female genital sensitivity and/or for modulating the erectile function in man, being an advantageous dosage form alternative to the oral or injectable administration of medications or even the intraurethral administration of pills.

A urinary catheter caddy for storing a plurality of packages of urinary catheters and for holding a selected one of the plurality of packages for dispensing of the urinary catheter therefrom includes a caddy body forming a storage space sized to receive and hold a plurality of packages of urinary catheters. An access opening extends from outside the caddy body into the storage space so a user can select one of the urinary catheter packages and pull an openable end of the selected package through the access opening with the opposite end of the package remaining in the storage space. The package is opened to expose a portion of the urinary catheter and an opened portion of the package is held by a package material holder so the catheter can be pulled by the exposed portion from the opened package without contaminating the catheter.

Urinary catheter-insertion kits can include a working tray, a storage tray, a protective paperboard, and a urinary catheter assembly, including a urinary catheter and a drainage system. The working tray can be nested on top of the storage tray. The working tray includes preformed sections configured to accommodate components of the urinary catheter-insertion kit. Methods of urinary catheterization include use of the urinary catheter-insertion kits.

A three-way urology catheter stopcock includes a stopcock body defining a longitudinally extending fluid flow passage, the body having three connector mounting openings in a wall thereof, an on/off selector movably mounted within the fluid flow passage of the body, the on/off selector including a longitudinally extending, cylindrical selector body having an open end, a closed end, and three fluid flow openings in a wall of the selector body, wherein the closed second end includes one of a plurality of fluid flow indicator members and fluid flow indicia, two first connectors mounted in opposing connector mounting openings of the stopcock body, and a second connector mounted in the connector mounting opening that is between the openings in which the two first connectors are mounted.

The present disclosure describes a system for the delivery of therapeutic substances to the cavities of a patient. The system can include a wearable micropump that is fluidically coupled with a handpiece. The handpiece can be inserted, for example, into the middle ear via a surgical tympanotomy approach. The system can enable a controlled injection of a therapeutic substance directly into the patient's cavity.

An stent delivery system may include a delivery device and a tubular body having a lumen sized to slidably fit about an outer diameter of the delivery device and a drainage stent having an anchoring mechanism, wherein the delivery device includes a constraining member configured to engage an external portion of the tubular body at the proximal end of the delivery device. A method of delivering a stent may include inserting a tubular body into the port of an endoscope, inserting a stent delivery device and a stent having an anchoring mechanism into the tubular body, wherein the delivery device includes a constraining member configured to engage and retain the tubular body at the proximal end of the delivery device, advancing the drainage stent distally through the tubular body, sliding the tubular body proximally, and engaging an external portion of the tubular body with the constraining member.

A drug eluting guide wire comprises a body aperture having low friction characteristics. The guide wire includes an effective leading end segment that is formed along its outer surface with a rapid action body aperture drug eluting agent serving as a vasilodating substance. The low friction characteristics are achieved by the leading end segment of the wire being covered with a low friction lubricating substance such as hydrogel that is loaded with a drug eluting substance in the form of isoprenaline in constituting the segment. Isoprenaline serves a constricted body aperture rapid action relaxing function in amongst others, or at least the case of the guide wire, is used to access a kidney along a ureter in response to temporarily paralyzing the smooth muscles of the ureteric wall resulting in widening of the lumen of the ureter.

a dilatable balloon catheter, comprising: a guide wire inserted and disposed in the inside of the catheter, an operation portion is fixedly connected to one end of the catheter, a balloon is disposed at the outer side of the catheter remote from the operation portion, the lumen of the catheter and the inner cavity of the balloon are connected by a communication structure provided on the catheter, the guide wire includes a first guide wire and a second guide wire which are separated from each other, the rear end of the first guide wire is connected to insertion-extraction structure in the rear end of the operation portion, the second guide wire is fixed to the inside of the catheter by a fixing process. The guide wire of the dilatable balloon catheter and the liquid injection lumen can share the same lumen, greatly reducing the diameter of the catheter in the present invention, so that the dilatable balloon catheter can be inserted into a narrow duct or lumen that needs to be expanded in human body through an device channel of an endoscope, and realize visualization operation.
