  • Publication number: 20140052272
    Abstract: In one embodiment, a stent includes a retention portion and an elongate portion. The retention portion is configured to help retain the stent in place within a body of a patient. The elongate portion extends from the retention portion. The elongate portion has a sidewall defining a lumen and the outer surface of the sidewall includes a pattern. The sidewall has a first section and second section. The first section of the sidewall has a first thickness. The second section of the sidewall has a second thickens different than the first thickness.

  • Patent number: 8545869
    Abstract: The resorption of a medical implant can be controlled with the use of particles embedded in a resorbable bulk material forming the implant or portion thereof. The implant can be removed from a body of a mammal by natural biological mechanisms after use. The resorption of the implant can involve swelling and/or hydrolyzing of the particles within the implant upon contact with a body fluid such that porosity and flow of fluid within the bulk material of the implant is increased. Resorption of the implant may also involve the use of particles with magnetic properties embedded within the implant such that an applied magnetic field causes the particles to vibrate within the bulk material thereby increasing the porosity and thus the flow of fluid, hence facilitating resorption of the implant. The resorption rate of the implant can be controlled by modulating swelling, hydrolysis, or movement of the embedded particles.

  • Publication number: 20130225918
    Abstract: In one embodiment, a medical device includes a resorbable material that is configured to be disposed within the body of the patient proximate a bodily implant. The resorbable material is configured to frictionally retain the implant in place within the body of the patient for at least a period of time. In one embodiment, a kit includes an implant and a resorbable material. The implant is configured to be disposed within a body of a patient. The resorbable material is configured to be disposed within the body of the patient proximate the implant to frictionally retain the implant in place within the body of the patient for a period of time. The resorbable material is configured to be resorbed by the body after the period of time.

  • Publication number: 20130072759
    Abstract: A medical device and method for facilitating a surgery through a body opening is disclosed. The medical device includes a flexible member configured to be placed within the body opening so as to cover a portion of the body opening. The flexible member includes a distal end portion with a closed end, a proximal end portion with an open end and an elongate portion joining the proximal end portion and the distal end portion. The proximal end portion is configured to extend out of the patient's body opening to cover an area around and outside the patient's body opening.

  • Publication number: 20130060078
    Abstract: A bodily implant is provided to support body tissues of a patient. The bodily implant includes a strip having a first portion and a second portion. The strip is configured to be stretched in a manner such that the second portion is stretched from a first length to a second length. The second portion of the strip is configured to maintain the second length. The strip is further configured to be disposed proximate to the patient's body tissues.

  • Publication number: 20120165659
    Abstract: In some embodiments, an implant includes a substrate and a radiopaque portion. The radiopaque portion is coupled to the substrate. The radiopaque portion has a first portion extending along a first axis and a second portion extending along a second axis different than the first axis. In some embodiments, the substrate has a perimeter that defines a shape having a first size. The radiopaque portion forms a shape having a second size. The shaped formed by the radiopaque portion is substantially the same as the shape defined by the perimeter of the substrate. The first size is greater than the second size.

  • Patent number: 6693089
    Abstract: A method of reducing adhesion at a site of trauma includes forming a film from an alginate solution, contacting the film with a cross-linking solution to form a cross-linked mechanically stable sheet, and placing at least a portion of the sheet at the site of trauma. An anti-adhesion barrier includes a sheet of ionically cross-linked alginate having a thickness in a range of 0.25 mm to 10 mm. The sheet has a tear strength sufficient for suturing and repositioning. A drug delivery device includes a cross-linked alginate container that can be filled with a drug.
