摘要： A balloon catheter 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; the balloon catheter comprising: An elongated balloon; a coating layer overlying an exterior surface of the balloon wherein the coating layer includes one or more water-soluble additives and an initial drug load of a therapeutic agent; and a length-control mechanism (600) which stretches and elongates the balloon during deflation, giving the balloon a smaller cross-sectional deflated profile for tracking through the body lumen and for removal after treatment.

摘要： 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.

摘要： Irrigation devices, methods, and systems are disclosed. The system comprises a catheter with one or more lumens and an expandable portion. One or more pumps are used to supply a mixture of contrasting and dilating agents in an interior kidney volume and flush a portion of the mixture out of the interior kidney volume. The method comprises placing a catheter into the interior kidney volume through a ureter, occluding a portion of the ureter with a distal end of the catheter, forming an exit port through an exterior kidney surface, flowing the contrasting and dilating agents through the one or more lumens to supply the mixture in the interior kidney volume, and flushing a portion of the mixture out of the exit port.

摘要： Ureteral bypass devices and procedures for performing internalized urinary diversions within patients. Such a procedure includes implanting a first catheter and securing a distal end of the first catheter within the renal pelvis or ureter of a patient, implanting a cystostomy catheter through and securing a distal end of the cystostomy catheter within the urinary bladder of the patient, fluidically connecting proximal ends of the first and cystostomy catheters to an adapter, and then subcutaneously implanting a sampling/flushing port and fluidically connecting a proximal end of the sampling/flushing port to the adapter via a third catheter to yield an artificial ureteral bypass device, in which the first and cystostomy catheters are fluidically connected together and fluidically connected to the subcutaneously-placed sampling/flushing port.

摘要： In one example, a system includes an elongated body defining a lumen where the elongated body includes a proximal portion and a distal portion. An anchoring member may be positioned on the proximal portion of the elongated body. The system further includes a sensor located on the elongated body where the sensor may be configured to sense at least one flow parameter of a fluid within the lumen. In some examples, the system includes processing circuitry configured to determine at least one of a density parameter or a temperature parameter of the fluid in the lumen based on the sensed at least one flow parameter of the fluid.

摘要： An intermittent urinary catheter assembly comprising an intermittent urinary catheter comprising a catheter tube (4) with a proximal insertion end (3) and a distal outlet end, the catheter tube comprising a plurality of draining openings (6) at a proximal portion, a handle connected to the distal outlet end of the catheter tube (4), where the handle (30) comprises a first cavity (31) and a coaxial second cavity (33), the first cavity being adapted to provide a through-going hole for draining liquid (urine), and a protective tube (40) adapted for being telescoped in a longitudinal direction between a first proximal position and a second distal position, wherein, in the first proximal position, the protective tube (40) at least partly covers the catheter tube and, in the second distal position, the protective tube is positioned in the second cavity of the handle thereby exposing the full length (L) of the catheter tube for insertion.

摘要： Posture-responsive therapy is delivered by the medical system based on posture state input from only one of multiple posture sensors at any given time. An example implantable medical system includes a first posture sensor and a second sensor. A processor controls therapy delivery to the patient based on at least one of a patient posture state or a patient activity level determined based on input from only one of the first or second posture sensors. In some examples, one of multiple posture sensors of an implantable posture-responsive medical system is used to automatically reorient another posture sensor (of the system), which has become disoriented. The disoriented posture sensor may be automatically reoriented for one or more posture states at a time.

摘要： A method for removing fluid from a patient is provided, the method including: deploying a ureteral stent or ureteral catheter into a ureter of a patient to maintain patency of fluid flow between a kidney and a bladder of the patient; deploying a bladder catheter into the bladder of the patient, wherein the bladder catheter comprises a distal end configured to be positioned in a patient's bladder, a drainage lumen portion having a proximal end, and a sidewall extending therebetween; and applying negative pressure to the proximal end of the bladder catheter to induce negative pressure in a portion of the urinary tract of the patient to remove fluid from the patient. Systems and kits related thereto also are provided.

摘要： A guidewire, methods of manufacture, and methods of use is described. The guidewire may include a core having one or more preformed ribs along a portion thereof. The ribs may form a portion of the outer surface of the guidewire or form a texture or shape of the outer surface of the guidewire. The ribs and outer texture of the guidewire can beneficially help the guidewire remain in a desired location in a body and help prevent or limit migration. Forming the ribs on the outer surface of the core may enable the guidewire to have greater rigidity and stiffness. The core may include a reduced diameter region distal of the ribs. The guidewire may include a cap over the reduced diameter region of the core.
