A device for positioning a stent in a natural canal after passing through an obstacle at the level of a target organ. The device includes a stent, a pusher tube, and a guide. The guide is configured to push the stent through the lumen of the natural canal, and includes at least one flexible part having a predetermined longitudinal stiffness and a lateral flexibility that allow a reversible deformation from a straight position to a bent position so as to follow the curve of the natural canal under the application of minimal external forces exerted by an operator. The device is particularly adapted to the technical field of urology.

Device for positioning a stent

Therapeutic device intended for the selective cytoreductive treatment of an obstruction in a natural lumen or passage of the human or animal body, said lumen being obstructed by the effect of a local cell proliferation, said device comprising a tubular element, in particular of cylindrical shape, intended to be placed in said natural lumen and sufficiently flexible to conform to said natural lumen, but sufficiently rigid to maintain an artificial channel in said lumen. The tubular element supports lengthwise a medicinal sleeve which is intended to come into line with, and into contact with, the obstruction once the natural lumen has been intubated, and is designed to deliver locally, at least in its outer surface portion, at least one therapeutic agent which is cytoreductive, in particular cytotoxic, through contact with the cells under whose effect said lumen is obstructed.

The present invention is an endo-prostatic stent and a detachable catheter apparatus including the same, allowing the correct positioning of the stent using tactile feed-back of the operator during insertion i.e. without the need for any imaging means like endoscopy or sonography.

A stent device and methods for inserting and removing a stent to and from an anatomical tract of a living being. The stent includes a distal segment and a proximal segment joined by a flexible connection structure. The stent is inserted using components comprising a delivery assembly such that the stent proceeds through the anatomical tract and seats the flexible connection structure of the stent in a natural constricting structure of the anatomical tract. The flexible quality of the connection structure permits the natural constricting functions of the anatomical tract to occur. The natural closure of the anatomical constricting structure stops the flow of fluid, for example, from a target organ which indicates that the stent is properly placed within the anatomical tract.

A prosthesis intended for the treatment of a natural lumen or tract of a human or animal body through which a flow is effected on either side of a sphincter is disclosed. The prosthesis comprises at least one tubular element, in particular of cylindrical shape which is sufficiently flexible to conform to the natural lumen, but sufficiently rigid to maintain an artificial passage in the lumen, and is intended to be placed in the natural lumen. The wall of the tubular element comprises a relatively smooth and soft biocompatible material, such as silicone rubber, at least in its outer part.

A detachable catheter apparatus that conveys a fluid includes a tube assembly and an insertion device. The tube assembly extends along a longitudinal axis and includes a distal tube section having a closed end and an opposite opened end, a proximal tube section having a first end and an opposite second end and a connector fabricated from a flexible, deformable material. The connector connects the opened end of the distal tube section and the first end of the proximal tube section together. The distal tube section includes an orifice formed therethrough and sized to enable fluid to enter the distal tube section so that the fluid can flow into and through the distal tube section, the connector and the proximal tube section. The insertion device is slidably receivable by the tube assembly, and includes an elongated inner alignment rod having a contact end portion and an insertion end portion disposed opposite the contact end portion. The inner alignment rod is sized to extend into the tube assembly so that the contact end portion contacts the closed end of the distal tube section while the insertion end portion projects outwardly from the tube assembly.

A urethral probe having a front part and a rear part, and a microwave antenna connected to an external device for generating microwaves. The microwave antenna has its primary active heating part arranged in the urethral probe to be directed onto the prostatic tissues located at least at the level of the bladder neck in the working position. The urethral probe constitutes an essential element of a device for the therapeutic treatment of tissues by thermotherapy, more particularly tissues of the bladder neck of the bladder of a human being.

A device constituting a transrectal probe comprises a probe body made of a flexible self-supporting polymer material whose degree of flexibility is designed to enable it to comply with the shape of the rectum while having substantially no compression effect on the rectum when inserted therein; the degree of flexibility preferably being defined by a hardness on the Shore A scale of less than about 90. The invention makes it possible to achieve accurate, safe, and reliable positioning of an instrument for detection or therapeutic treatment level with an organ to be observed or treated, and in particular the prostate.

Transrectal probe

An obstructed canal of the human or animal body delimited by a wall is treated by: (a) selectively damaging extrinsic tissue by introducing a controlled dose of ionizing or non-ionizing treatment energy in order to necrose at least a part of the tissue; (b) fitting a prosthesis into the natural canal, the prosthesis including a tubular element biologically compatible with the wall, exerting on the latter a centrifugal compression, and optionally imparting a posture, and defining an open and permanent passage in the natural canal; (c) permitting the extrinsic tissue to heal on and around the prosthesis; and (d), after healing of the extrinsic tissue, extracting the prosthesis from the natural canal to obtain in the latter a definitive passage modeled on the external dimensions of the prosthesis.

An apparatus for the surgical treatment of tissues by thermal effect, in particular the prostate, is disclosed comprising a urethral emitting probe having a front end capable of being inserted in the urethra, provided with a microwave antenna located intermediate or in the vicinity of the front end, the microwave antenna being connected to an external microwave generating device, and working at a frequency and at a power effective to heat the tissues to a predetermined temperature for a period of time sufficient to treat the tissues by thermal effect.

The invention relates to a measuring method for automatically measuring the volume of a tumor or of a gland, and also to a measuring device. The measuring device comprises an endocavitary detector probe, in particular a transrectal probe, display means, the display means including an image-forming screen forming images of the tumor or of the gland as provided by the probe, outline-marking means for marking the outline of the image of the tumor or of the gland on the image-forming screen, thereby enabling a marked outline to be obtained, computer means for calculating the volume of the tumor or of the gland on the basis of the marked outline, and optional means for storing the marked outline. The invention makes it very easy for a practitioner to determine the volume of a tumor or of a gland to be treated.
