    摘要: A sterile connection apparatus is provided for enabling the connection of a first tube to a transfer tube of a medical solution container. The apparatus includes a housing having a cover portion which is adapted for interfitting with a base portion to provide a substantially closed interior volume. The first tube and the transfer tube of the medical solution container are introduced within the interior volume and the housing carries means located therewithin and operable from the outside of the housing for enabling manipulation of one of the tubes. In this manner, the first tube may be disconnected from and/or connected to the transfer tube. Means are provided for sterilizing the tubes within the substantially closed interior volume.

    摘要: This invention is directed to novel methods for gynecologic embolotherapy. The methods directly access the blood vessels to be embolized transcervically rather than arterially. The methods provide precise directed delivery of embolizing compositions, and are particularly suited for treating uterine fibroids. Kits containing one or more devices for transcervical injection and an embolizing composition are also provided. In a preferred embodiment, fluid embolizing compositions are used. In a more preferred embodiment, these fluid embolic compositions comprise a biocompatible polymer, a biocompatible solvent and a biocompatible water insoluble contrast agent. In a most preferred embodiment, the contrast agent is characterized by having an average particle size of about 10 μm or less.

    摘要: This invention is directed to compositions for embolizing vascular sites. The compositions described herein comprise fumed silica as a rheological modifier. The fumed silica imparts high viscosity to the compositions under static conditions but allows the compositions to flow readily under shear conditions. This invention is also directed to methods for treatment of aneurysms, arteriovenous fistulae, arteriovenous malformations, tumors, and other vascular diseases using the compositions described herein. Other uses are disclosed as well. Kits of parts including those compositions and devices which can deliver these composition are also described.

    摘要: Disclosed are methods useful for treating vascular lesions wherein a non-particulate agent such as a metal coil is introduced into a vascular site (e.g., an aneurysm cavity) in conjunction with an embolizing composition comprising a biocompatible polymer and a biocompatible solvent. The biocompatible solvent is miscible or soluble in blood and also solubilizes the polymer during delivery. The biocompatible polymer is selected to be soluble in the biocompatible solvent but insoluble in blood. Upon contact with the blood, the biocompatible solvent dissipates from the embolic composition whereupon the biocompatible polymer precipitates. Precipitation of the polymer in the presence of the non-particular agent permits the agent to act as a structural lattice for the growing polymer precipitate. In another embodiment, the biocompatible polymer composition can be replaced with a biocompatible prepolymer composition containing a biocompatible prepolymer.
