Publication number: 20080051694Abstract: In a medical treatment equipment (1), a sheath body (5) has a deformed tight coil structure in which a plurality of wire elements (7, 8) are formed triangular in cross section, and helically wound with one coil line turn alternately arranged in neighborhood of other coil line turn. An apex of the triangular cross section of the one coil line turn facing an inner diameter side of the sheath body 5, and an apex of the triangular cross section of the other coil line turn facing an outer diameter side of the sheath body 5. Lateral sides of neighboring triangular cross sections are relatively slidable each other at a mutual neighborhood side (9) in a radial direction when the sheath body (5) is bent. This prevents the sheath body (5) from developing a line gap (C) between coil line turns of the deformed tight coil structure, and protecting the sheath body (5) against a tensile load which would otherwise be applied when the sheath body (5) is curvedly bent within a somatic cavity.Type: ApplicationFiled: July 23, 2007Publication date: February 28, 2008Inventor: Tomihisa Kato

Publication number: 20080051733Abstract: An improved luer lock receiving septum having a configuration which provides rapid and tight resealing and yet allows penetration of the septum by the luer tip with a low penetration force. The elongated septum includes an upper portion of enlarged diameter having a target surface, a central slit, and a central, lower septum extension projecting about the slit below the upper portion and into a housing so that following luer insertion there is provided sufficient room for both the laterally displaced extension of the septum, the luer taper, and the housing to be received into a conventional luer lock connector. The septum is further preferably configured to minimize or eliminate the negative pressure deflection normally associated with the withdrawal of the large diameter luer cannula from an enclosed fluid filled lumen or chamber, by substantially isolating the lumen or chamber from the septum material displacement resultant from luer insertion.Type: ApplicationFiled: October 30, 2007Publication date: February 28, 2008Inventor: Lawrence Lynn

Publication number: 20080051734Abstract: Cannulas for surgical and medical use expand along their lengths. The cannulas are inserted through tissue when in an unexpanded condition and with a small diameter. The cannulas are then expanded radially outwardly to give a full-size instrument passage. Expansion of the cannulas occurs against the viscoelastic resistance of the surrounding tissue. The expandable cannulas do not require a full depth incision, or at most require only a needle-size entrance opening. In one embodiment of the invention, the cannula includes a number of arcuate plate segments movable with respect to each other for enabling an increase in cross-sectional area of the cannula lumen. In this embodiment, the cannula can be provided with a pointed end portion. The cannula may be expanded by inserting members or by fluid pressure. The cannula is advantageously utilized to expand a vessel, such as a blood vessel. An expandable chamber may be provided at the distal end of the cannula.Type: ApplicationFiled: October 31, 2007Publication date: February 28, 2008Inventors: Peter Bonutti, James Hawkins

Publication number: 20080051735Abstract: Devices are provided herein for translumenal access to a treatment site within a body cavity. In general, the devices include an elongate sleeve configured to provide access to a treatment site wherein various portions of the sleeve are associated with an anti-microbial agent. Additionally, the anti-microbial agent(s) can be disposed within a housing and/or inner lumen of the sleeve such that surgical instruments passing therethrough can be sterilized en route to and/or being withdrawn from the treatment site. Additionally, various methods are also provided herein for maintaining the sterility of a treatment site.Type: ApplicationFiled: July 10, 2007Publication date: February 28, 2008Applicant: ETHICON ENDO-SURGERY, INC.Inventors: John Measamer, Michael Cropper

Publication number: 20080051736Abstract: According to an aspect of the invention, an indwelling catheter is provided which comprises a catheter shaft. The catheter either comprises a light source or is adapted to receive light from a light source, and is configured such that light is transmitted from the light source into the catheter shaft. Moreover, the catheter shaft is formed of a polymeric material that transmits a quantity of light from the light source that is effective to inactivate microorganisms on a surface of the catheter shaft upon activation of the light source. For example, the light may inactivate the microorganisms directly or in conjunction with a photosensitizer. According to another aspect of the invention, a sterilization method is provided, which comprises activating the light source while the catheter is inserted in a subject.Type: ApplicationFiled: July 18, 2007Publication date: February 28, 2008Inventors: Robert Rioux, Raymond Lareau, Kristian Dimatteo

Publication number: 20080051737Abstract: A medical device is adapted for at least partial implantation into a body and includes first and second sections along the length of the device. A first therapeutic agent is associated with the first section and a second therapeutic agent is associated with the second section. The first therapeutic agent can be one or more antiproliferative, such as paclitaxel, a paclitaxel derivative, or a paclitaxel pro-drug, anti-coagulant, antithrombotic, thrombolytic, fibrinolytic, or combination thereof. The second therapeutic agent can be one or more antimicrobials, such as one or more antibiotics. Each of the first and second therapeutic agents can either be posited on one or more surfaces of the respective section, or impregnated within the section.
