Abstract: The invention relates to a negative pressure drainage device attached to dental tissue. The negative pressure drainage device has a negative pressure machine, a negative pressure tester, a negative pressure control valve and a sealing part. The negative pressure machine is connected to the negative pressure tester, the negative pressure tester is connected to the negative pressure control valve, and the negative pressure control valve is connected to the sealing part through a connecting part. The device, by using the apical foramina structure of the dental tissues per se, cannot only drain and form negative pressure in the cyst cavity, but also no longer need a long-term implantation of a negative pressure drainage artificial device in the jaw.

Abstract: A device includes a tubular endoprosthesis (11) and a hollow prop (13) provided in the vicinity of a distal end with at least one transverse retaining opening (23A). The device includes a releasable retaining member (31). It also includes filamentary line (33A) which forms an eyelet (41) around the retaining member (31), and a tightening loop (43) around the endoprosthesis (11), and which includes traction means (45) extending the tightening loop (43).

The invention is applicable to releasing endoprostheses in a blood vessel.

Abstract: A device includes an expandable implant and a hollow stent internally defining a central passage. The hollow stent defines a retention opening of the implant near the distal end thereof. The inventive device also includes a wire-type link for releasably fixing the implant to the stent, which has a traction section introduced into the opening and extending inside the central passage. For the wire-type link, the device includes an internal insulation channel arranged in the central passage and axially fixed with respect to the stent. The insulation channel receives only one wire-type link and defines a channel which is devoid of a link at least between the proximal end of the stent and the retention opening and is placed in the central channel.

Abstract: Method and apparatus for validating location information associated with an access point (AP) in a wireless local area network (WLAN) by subjecting neighborhood node proximity information retrieved from an AP and neighborhood node location information retrieved from a database to a likelihood ratio tests (LRT). The neighborhood node proximity information retrieved from an AP comprises a list of nodes exhibiting at the AP a signal strength above a threshold level T, or link quality information associated with those nodes having a signal received by the AP.

Abstract: An expandable stent comprising a tubular body made up of a plurality of separated tubular elements (1) arranged along a common longitudinal axis. Each tubular element (1) comprises a plurality of rhombic-shaped closed cell elements (2) joined by circumferentially extending linking members (3). The closed cell elements (2) are expandable to allow the tubular elements, and hence the stent itself, to expand. In the direction of the longitudinal axis of the stent, the extremities of each of the closed cell elements has an enlarged loop (30) with waisted portions (33) which allow the tubular elements to interlock to create a stable structure, at least when in the unexpanded condition.

Abstract: A device comprises an expandable implant (11) and a hollow stent (13) internally defining a central passage (14). Said hollow stent (13) defines a retention opening (23A) of the implant (11) near the distal end thereof (19). The inventive device also comprises a wire-type link (53A) for releasably fixing the implant (11) to the stent (13), which comprises a traction section (75A) introduced into the opening (23A), and extending inside the central passage (14). For the wire-type link (53A), the device comprises an internal insulation channel (29A) arranged in the central passage (14) and axially fixed with respect to the stent (13). The insolation channel (29A) receives only one wire-type link (53A) and define's a channel (41) which is devoid of a link at least between the proximal end (21) of the stent (13) and the retention opening (23A) and is placed in the central channel (14).
