Patent number: 11975165Abstract: A drug delivery system that includes an elongated inert support and at least two reservoirs containing a pharmaceutically active ingredient. The inert support has a number of wall segments that define at least two compartments arranged for accommodating the at least two reservoirs. The inert support is made of a material which prevents migration or diffusion of the active ingredient from one reservoir into the other or into the support. Since the drug delivery system is divided into compartments, one for each reservoir containing an active ingredient, the release rates of each active ingredient can be independently controlled or adjusted. This is due to the fact that there is no interaction between the active ingredients, and accordingly the active ingredients will not influence each other physically or chemically.Type: GrantFiled: September 11, 2014Date of Patent: May 7, 2024Assignee: QPHARMA ABInventors: John Ingvar Feldtblad Kendrup, Steen Alex Stavnshøj, Ian Peter Flawn Orpana

Patent number: 8347888Abstract: A gynaecological instrument for delineating the fornix of the vagina during laparoscopic surgeries having a spring, which proximal end is securely affixed to a distal end of a solid ring and the distal end of the spring is securely affixed to a base. The extension of the base can be inserted into the head of the Valtchev® Uterine Mobilizer and locked in place. When the delineator is pushed toward the fornix of the vagina the solid ring is self-adjusting to the angle of the of the fornix and the length of the cervix. An elastic plastic ring is provided, for placing on the solid ring, in order to protect the ring and instrument which is used to open the vagina laparoscopically.Type: GrantFiled: April 8, 2008Date of Patent: January 8, 2013Inventor: Konstantin Lazarov Valtchev

Publication number: 20120097172Abstract: An intrauterine device for applying force to a wall of a uterus to promote contraception without blocking the fallopian tubes may include an elongate member formed of a resilient material and having a default expanded configuration and a spring portion disposed approximately at a midpoint between two ends of the elongate member. The IUD may also include two tissue contact members, one tissue contact member disposed at one of the two ends of the elongate member and the other tissue contact member disposed at the other end. The tissue contact members may generate a laterally directed force against the wall of the uterus when the intrauterine device assumes its default expanded configuration.Type: ApplicationFiled: November 10, 2011Publication date: April 26, 2012Inventors: Michael G.

Publication number: 20100300452Abstract: An intrauterine device for applying pressure to the walls of the uterine cavity includes a resilient body having an elongated member which includes a first end and a second end which are resiliently biased away from each other. The first end of the elongated member includes a first leg having a first end and a second end. The second end of the elongated member includes a second leg having a first end and a second end. A connection member is positioned between the first end of the first leg and the first end of the second leg. A first plug member is secured at the second end of the first leg and a second plug member is secured at the first end of the second leg. The first and second plug members are shaped and dimensioned for bearing against the walls of the uterine cavity as the elongated member spreads outwardly with the first end and the second end moving apart. A method for preventing conception within the uterine cavity is also disclosed.Type: ApplicationFiled: August 16, 2010Publication date: December 2, 2010Inventors: Michael G. Tal, Patrick N.
