The invention relates to devices (1) for draining or closing a natural or artificial bladder outlet by means of a balloon body (3) made of preferably micro-scale thin-walled Polyurethane, which has a vesical anchor, is transurethrally sealing and is extended into the urethra or through the urethra. According to the invention, the balloon body is seated on a shaft body (2) supporting the balloon, and the filling of the balloon body is preferably done with air.

A dilator device including an elongated flexible material sleeve having a hollow interior extending along a distal portion and a proximal portion thereof. An expandable or inflatable bladder is connected to the distal portion and disposable radially outward from an exterior of the sleeve when in an expanded and/or inflated orientation. The elongated sleeve comprising a tip having a predetermined configuration that facilitates positioning the elongated sleeve within an intended body part. A fluid input is structured for removable connection to a fluid source and is disposed on the sleeve, in fluid communication with the bladder. An access opening is formed on the proximal portion and is cooperatively dimensioned with the hollow interior to removably receive any one of a plurality of different types of positioning instruments within the sleeve.

Balloon guide catheter with a balloon bonded thereto maximizing bonding strength and integrity while minimizing outer profile. Reflow jacket(s) is melted to/embedded within a braid supporting structure of the catheter securing beneath the balloon. Radially arranged apertures and/or recesses may be defined in the balloon through which adhesive is seepable upwards when secured about the catheter shaft. Proximal and distal bond interface areas of the balloon may be skived at right angles into two sections each extending radially 180°. Proximal and/or distal edges of the balloon may be flipped inwards prior to securing to the catheter shaft to form respective proximal and/or inverted bonds. During prepping of the catheter, residual air may be purged from the balloon via an exhaust hole defined in the compliant balloon or an exhaust tube secured between the exterior surface of the catheter shaft and the balloon.

The invention is directed to a device in the form of a tube or catheter for draining and/or sealing a natural or artificial bladder outlet, comprising a shaft body that can be applied from extracorporeal into a bladder of the patient, as well as a balloon that surrounds the shaft body like a cuff and is placed in the bladder for the purpose of a vesical anchoring of the shaft body in the bladder, wherein the shaft body, which is produced by means of molding, is having a profile with a wavy corrugation, providing the shaft body with a radial stability and with a kink-free axial bending property.

Minimally invasive catheter relates to the field of eversible catheters. It is primarily intended for use as a urinary catheter, but is also usable in other fields. As a urinary catheter this minimally invasive catheter 1 used as an indwelling or intermittent catheter with transurethral or suprapubic approach. This catheter has specific technical solution for eversible motion where tubular membrane 2, attached between distal part 36a of the handle 36 and distal part 3a of the inner tube 3, can in one case free slide between these two parts and in another be fixed to form hermetically sealed space 14. Free sliding of membrane ensures eversible principle of motion during placement and withdrawal of the catheter 1. Fixation of membrane allows a formation of hermetically sealed space 14 with fluid to make catheter surface smoother and softer, and a balloon 33 to hold catheter 1 in place for prolonged period of time. Thus, present invention provides a urinary catheter that enables the reduced incidence of complications arising due to its application.

A clot capture catheter comprises an elongate tubular shaft having a proximal end, a distal end and an inflatable expansile member at the distal end. The expansile member is inflatable from a collapsed delivery configuration to an expanded configuration. In the expanded configuration, the expansile member extends to define a funnel shape having an enlarged distal clot entry mouth at the distal-most end of the catheter. In the expanded configuration, the expansile member may extend distally beyond the distalmost tip of the shaft. The expansile member may be integral with the distal tip of the catheter shaft.

A device for emptying stool from the rectum of a patient by means of a shaft body which is introduced into the bowel via the anus and is able to buckle or fold axially and radially, and which is provided with a dumbbell- or hourglass-shaped balloon body for assuring the transanal positioning of the device. The invention is further characterized by the special design of and choice of material for the shaft body and the balloon envelope and by the specific positioning of the balloon body on the shaft body, wherein the axial deflection of the free forward end of the shaft body is limited or an uncontrolled deflection of the shaft is prevented, and the probability of perforation of the bowel wall under the effect of force acting on the shaft body from an axial direction is therefore decisively reduced by the intestinal tube described according to the invention.

An everting balloon system is disclosed that can be used for the placement of an IUD within the uterine cavity of a female patient. The everting balloon system with IUD can be used to access a uterine cavity at specific locations in the fundus. A one-handed IUD delivery system for placement with an everting catheter is disclosed. An IUD loading system for placement within an everting catheter is disclosed. The everting catheter with an IUD can simplify the process of IUD placement within the uterine cavity.

A device and system for thermally affecting tissue that includes a balloon catheter with a reduced distal length for ease of navigation and that also includes a balloon that is more resistant to bursting and delamination. The balloon may include a proximal neck generally attached to an elongate body and a distal neck generally attached to a shaft disposed within the elongate body. The distal neck is turned inward to extend within the balloon chamber and the proximal neck may either extend within the chamber or extend proximally away from the balloon chamber. Alternatively, the device may include an inner balloon and an outer balloon, the distal necks of both being turned inward and extending within the inner balloon chamber. The proximal necks may both also be turned inward to extend within the chamber or the proximal neck of the outer balloon may extend away from the balloon chamber.

Everting balloon systems and methods for using the same are disclosed herein. The systems can be configured to access and dilate body lumen and cavities. For example, the systems can be used to dilate the cervix and access the uterine cavity. The systems can also be used to occlude the cervix. The systems can also be used to occlude the urethra.
