摘要:
The invention provides a ureteral stent including an axis defining flexible tube. The flexible tube is configured to form a proximal end and a distal end. The proximal end is capable of forming a retractable loop away from the axis. The distal end is configured to form two distinct regions. The first region has a partially rigid structure situated proximal to the distal end and the second region is capable of forming a retractable loop formed out of the first region.

The present disclosure is directed to methods, compositions, devices and kits which pertain to the attachment of stent-containing medical devices to tissue.
摘要:
Placement of a stent having a tethered ferromagnetic bead may be facilitated with a modified pusher having an opening at the distal end of the pusher to receive the tethered ferromagnetic bead. The ferromagnetic bead may be positioned within the bladder whereby a tether connection to a shortened stent ending within the ureter may be used to reduce the likelihood of patient irritation. The bead, tether, and stent assembly may be advanced into the patient as a unit along a conventional guide wire and using a conventional cystoscope.
摘要:
Various methods and devices for diagnosing, monitoring, and/or treating medical conditions through an extra-anatomic opening, port or channel or other opening through an airway wall are provided. The creation of collateral channels or extra-anatomic openings may provide convenient access points to the lung parenchyma or other tissue for delivery of substances, tools, or devices to diagnose, monitor, or treat structures, tissue, tumors or diseased tissue that may reside within the lung. The use of such openings allows for diagnosis, monitoring, or treatment in a minimally invasive manner and efficiently delivering needed substances, tools, or devices to the desired area.
摘要:
Die Erfindung bezieht sich auf eine Vorrichtung zur Zufuhr eines medizinischen Implantats (10) in einen Körperhohlraum mit einem Zufuhrelement (11), wobei an einem Ende (12a) des Zufuhrelementes (11) eine Haltefläche (13) für das Implantat (10) ausgebildet ist, das Ende (12a) mit der Haltefläche (13) im Körperhohlraum platzierbar ist und die Haltefläche (13) angepasst ist derart, dass das Implantat (10) zum Freisetzen im Körperhohlraum von der Haltefläche (13) lösbar ist.
摘要:
Apparatus and methods are described for killing cancer cells (44) of a subject, the subject having cancer cells and healthy cells. The apparatus includes a plurality of first molecules (40) configured to be coupled to the cancer cells to a greater extent than to the healthy cells, in response to being administered to the subject. A plurality of clusters (42) of phase-change molecules are provided, each of the clusters coupled to a respective one of the first molecules. An energy transmission unit (50) kills cancer cells coupled to the first molecules by heating the cancer cells, by transmitting energy toward the clusters that selectively heats the clusters. Other embodiments are also described.
摘要:
An implant for creating incisions in the tissues surrounding the bladder neck and the urethra of a patient, for relaxing the opening of the bladder, the implant includes a central connector and at least one wire, the wires extend radially outwardly from the center of the central connector, the wires apply continuous pressure on the surrounding tissues, the wires are foldable within an implant sheath for enabling delivery and extraction thereof, the implant is implanted within a restricted location of the urethra for a period of time for creating incisions at the locations where the wires apply pressure on the surrounding tissues.
摘要:
A radiation and radiochemically sterilized, multi-component, fiber-reinforced composite, absorbable/disintegratable urinogenital stent, such as an endoureteral stent, with radiomodulated residence time in the biological site of 1 to 10 weeks depending on the high energy radiation dose used for sterilization.
摘要:
An implantable, radially distensible stent (10) includes a tubular structure having opposed open ends (14, 16). The wall (10) of the stent (12) is made from a shape memory polymeric material. Grooves (22) may be disposed within an outer surface (20) of stent wall (12) to improve flexibility and drainage of the stent (10).
