  • Patent number: 10232149
    Abstract: An introducer set includes an introducer and dilator along with an extension in a sealed sterile peal open package. The extension is available for use during procedures where the puncture access site to the patient is close enough to the site to be treated in the patient that the physician's hands and/or head may be positioned in the fluroscopic area while the physician is attempting to maneuver a wire guide to a desired location. When the extension is attached to the introducer, the physician may perform a procedure, such as an antigrade stick in the lower leg of a patient, while maintaining their hands and head outside of the fluroscopic area while direct radiation is being supplied and the wire guide is being maneuvered to a desired treatment location.

  • Patent number: 10058635
    Abstract: Provided are surface treatment agents that enable surfaces with a chemically fixed lubricant to be produced instead of a resin coating which has drawbacks, such as that lubricity is reduced due to separation, peeling or the like of the coating during the movement within a vessel or tube; and medical devices, such as catheters, having a surface at least partially treated with such a surface treatment agent. The present invention relates to a surface treatment agent for medical devices which contains a copolymer of a hydrophilic functional group-containing monomer and an epoxy group-containing monomer.

  • Patent number: 9962517
    Abstract: Problems associated with BPH can be negated using the present ergonomically pre-contoured, valved urinary catheter. To insert, the flexible tee beam is oriented on axis with the upper catheter. It will self-toggle into the tee orientation once inside the bladder, because of a small-bore elastic tubing that extends full length inside the main catheter. The catheter assembly will remain in place until the user tugs down hard enough on the outside-the-body, small diameter, valve-actuation tensor to cause the tee beam to fold double and be small enough to be pulled from the urethra. Lesser tugs actuate the compact, distal-end valve to allow urine flow. The smooth outer surfaces of the catheter assembly will help assure that reproductive functions will not be affected.

  • Patent number: 9872786
    Abstract: A satiation device is described which includes a sheath or liner extending from the proximal or middle stomach to the distal antrum. Food ingested by the patient passes through the sheath or liner, thereby minimizing contact between the ingested food and the stomach. It is believed that over time, reduced contact between food and the stomach will result in decreased Ghrelin production by the patient and a consequent decrease in appetite. In some embodiments, the satiation device may also include a proximal pouch and/or a distal bypass tube.

  • Patent number: 9844652
    Abstract: In a stent kit in which a stent tube has an arc-shaped part at one or both ends, an inner catheter includes an arc-shaped part fitting in, and conforming to, each arc-shaped part of the stent tube. Because of the conforming shapes, the stent tube is not deformed by the inner catheter even if the inner catheter remains within the stent tube over a long time. Consequently, the arcuate shape of the arc-shaped part or parts of the stent tube are reliably restored when the inner catheter is pulled out.

  • Publication number: 20150094696
    Abstract: A multi-lumen catheter, for insertion into and draining a body cavity, that mitigates the risk of obstruction of the drainage ports and drainage lumen of the catheter, reduces the detrimental effects caused by the suction forces of the drainage ports on the body cavity being drained, and reduces the risk of infection of the body cavity being drained by decreasing the residual volume of fluid retained in the body cavity being drained. These advantages are achieved by the novel approach of disposing a perforated filter membrane or a membrane having a relatively large entry port(s) between membrane struts over a segmented retention element and also over the drainage port(s) of the drainage lumen of the catheter thereby creating internal interstitial drainage channels and internal interstitial drainage cavities.

  • Publication number: 20150051587
    Abstract: A method for manufacturing an elongated element (200) is provided. The method comprises arranging a molding cavity (101), defined by a mold (103) and a mold insert (104), said mold insert (104) comprising a mold core (105) and a displaceable mold cavity wall (106), said displaceable mold cavity wall (106) being arranged between the mold (103) and the mold core (105), such that the molding cavity has a start volume in a start position of the displaceable mold cavity wall (106). Then a liquid material is injected into a proximal end (102) of the molding cavity (101), where after the displaceable mold cavity wall (106) is displaced in relation to and along with the mold (103) and the mold core (105), distally during said injection, to increase the molding cavity volume from the start volume into an end volume at an end position of the displaceable mold cavity wall (106), wherein the molding cavity (101) in said end position of the displaceable mold cavity wall (106) corresponds to the elongated element (200).

  • Publication number: 20150051588
    Abstract: A catheter having a longitudinal body includes a rotational fitting located thereon, thus defining a distal longitudinal body portion distal of the fitting and a proximal longitudinal body portion proximal of the fitting. The respective proximal and distal longitudinal body portions are independently moveable from each other such that movement of one of the proximal and distal longitudinal body portions of the catheter, such as during removal and/or replacement of a urine drainage bag from the proximal end of the catheter, does not impart movement to the distal longitudinal body portions of the catheter that may be located in the patient's urethra and bladder. Methods of handling a drainage catheter and for removing a fluid collection bag from a catheter assembly are also disclosed.

  • Patent number: 8956340
    Abstract: A urethral catheter assembly utilizing a removable guide wire for navigating the catheter through a patient's urethral lumen during the insertion procedure. The guide wire being very flexible and having a low coefficient of friction, thus reducing the likelihood of injuring or puncturing the urethra during insertion. The guide wire extends beyond the distal end of the catheter assembly to ensure that the flexible tip of the guide wire is the first contact point between the catheter assembly and the urethral lumen. In one embodiment, the guide wire extends beyond the proximal end of the catheter assembly and is adapted to be handled by a medical doctor to manually maneuver the guide wire through the urethra.

  • Publication number: 20150038947
    Abstract: A medical device is disclosed, comprising a substrate and a hydrophilic surface coating arranged on said substrate. The substrate has, on its surface coated with said hydrophilic surface coating, a surface texture with an arithmetical mean deviation of the surface profile (Ra) of at least 3 ?m and/or a profile section height difference (Rdc (1-99%)) of at least 18 ?m. It has surprisingly been found that the increased surface roughness of the substrate provides significant improvements in e.g. water retention for the hydrophilic coating.

  • Patent number: 8939962
    Abstract: The embodiments herein provide an atraumatic urinary catheter. The atraumatic urinary catheter has a first tubule, a second tubule and a third tubule. The first tubule is provided with a first channel and a second channel. The first channel is wide and extended from a proximal end to a distal end of the first tubule and the first channel is open in both ends. The second tubule comprises a third channel, which is connected to a bladder cavity. The third tubule placed on the first tubule and the second tubule as a cover, to form a catheter's balloon. In order to avoid balloon explosion, the sterile water in the balloon is drained by the self-retaining mechanism of the catheter to prevent an irritation and tissue traumatization.

  • Publication number: 20150018805
    Abstract: Devices, systems, and methods are disclosed which relate to a catheter cap which seals a reservoir of a catheter introducer. The catheter cap secures over an introducer tip to prevent airflow into the introducer tip. The catheter cap utilizes an elongated stem to block a distal opening of the reservoir to further prevent airflow. A lip of the catheter cap may further engage an insertion stop point of the catheter introducer to secure the catheter cap. The catheter cap ensures proper lubrication of the introducer tip and the catheter during insertion of the catheter into the urethra of a user.
