摘要:
Various embodiments disclosed relate to drug-coated balloon catheters for treating strictures in body lumens 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.

A suction stent for introduction into a hollow organ of the human or animal body, preferably into the gastrointestinal tract, in particular the intestine, includes a tubular hollow body which is open in the longitudinal direction and made of biocompatible material. The tubular hollow body has a fixed diameter at least in its central portion. A porous shapeable material, preferably a sponge material, which is biocompatible and shapeable in the radial direction, radially sheaths the tubular hollow body at least in a section of the tubular hollow body. A method for sealing a leakage, especially an anastomosis, of the hollow organ utilizes the stent.

An apparatus includes a housing, a first cannula, and a second cannula. The housing defines an inner volume having a first portion in fluid communication with a first set of openings, and a second portion in fluid communication with a second set of openings and fluidically isolated from the first portion. The first cannula has a proximal end portion fluidically couplable to a vacuum source and a distal end portion coupled to the housing such that the first portion of the inner volume and a lumen defined by the first cannula fluidically couple the first openings to the vacuum source. The second cannula has a proximal end portion fluidically couplable to a fluid source and a distal end portion coupled to the housing such that the second portion of the inner volume and a lumen defined by the second cannula fluidically couple the second openings to the fluid source.
摘要:
A balloon catheter comprises a catheter and a balloon located on the distal end of the catheter. A pair of stimulating electrodes for receiving a constant current stimulating signal when the balloon is inflated with an electrically conductive medium and a plurality of sensing electrodes for producing voltage response signals are located on the catheter. The voltage response signals are indicative of the values of the transverse cross-sectional area of the balloon adjacent the sensing electrodes. A first lumen accommodates the inflating medium to and from the balloon, and a second lumen accommodates electrically conductive wires to the stimulating and sensing electrodes. A pressure sensing element is located in a protective housing in the second lumen, and communicates through a communicating opening in the protective housing and through a communicating port in the catheter with a hollow interior region of the balloon. The balloon catheter may also be provided with a guide wire engaging element for engaging a guide wire externally of the balloon catheter.

There are provided devices for applying negative pressure to a wound in an endoluminal surface of a patient to facilitate healing of the wound and methods for use of the devices. The device (69, 94, 134, 140, 156, 164) comprises a flexible porous element with an outer face defined between opposite proximal and distal ends of the porous element. A suction tube (30) for being connected to a suction source externally of the patient's body is in fluid communication with the porous element (14) to apply the negative pressure to the wound via the outer face of the porous element. In some embodiments, the porous element has a longtitudinal passageway (16) for passage of bodily substances of the patient along the lumen defining the endoluminal surface through the porous element. In such embodiments, the device may also have at least one absorbent element (70, 80) for absorbing the bodily substances and which is disposed forwardly or rearwardly of the porous element (14). Embodiments of the device may also include a drainage tube (22) for collection and drainage of bodily substances from the patient and which is received in the longtitudinal passageway (16) of the porous element. In other embodiments, the porous element can be in the form of a mat wrapped around a feeding or other insertion tube. The porous element of a device embodied by the invention may also include one or more irrigation channels (85, 86) for delivery of an irrigation fluid into or though, the porous element. The porous element and/or absorbent element(s) may be sponge(s).

An anal irrigation kit provides an improved approach for emptying a bowel by instilling irrigation liquid and stimulating the rectal wall simultaneously. The anal irrigation kit includes an irrigation liquid reservoir, a hand pump, and a soft flow manifold, which can be folded for insertion into a rectum.
摘要:
The present disclosure describes a cecostomy tube having a head with an opening and a valve. There is a flexible catheter with a lumen having proximal and distal ends, the proximal end of the catheter in fluid communication with the opening in the head, a portion of the catheter extending away from the head to define the distal end. The catheter also has walls defining inside and outside surfaces from the opening defined in the head to the distal end of the catheter. There is a retainer provided on the distal end of the catheter. The retainer can change shape from a first profile or configuration to a second profile where the second profile is larger than the first profile and the second profile is adapted to retain the cecostomy tube in place in a body. The device may be placed in a single, initial surgical operation.
