A device for sealing an opening or puncture in the wall of a blood vessel or other percutaneous openings. The device includes a shaft section of a small diameter, with an expandable balloon and atraumatic tip at its distal end. The proximal end of the device has an inflation/deflation port which is utilized to inflate the balloon once it is in place within the blood vessel or other body cavity. The entire device is typically placed through a vascular sheath, which is used during invasive percutaneous vascular procedures. The balloon is inflated and withdrawn until it engages the inner surface of the blood vessel or body cavity. The sheath is withdrawn from within the blood vessel or other body cavity to the outside of the body. A fixation collar loaded onto the shaft of the device allows for securement in place, within the blood vessel or other body cavity.
A medical sealing apparatus for closing of an aperture in a patient body, comprising: a. a thin, elongated conduit having a central lumen, said conduit having proximal and distal ends, said conduit distal end being insertable into the patient body aperture and having an inflation segment including a
A medical sealing apparatus for closing of an aperture in a patient body, comprising: a. a thin, elongated conduit having a central lumen, said conduit having proximal and distal ends, said conduit distal end being insertable into the patient body aperture and having an inflation segment including an external orifice which is communicatively connected to said lumen, said conduit proximal end having a cylindrical configuration of a uniform outside diameter; b. an expandable member sealingly disposed at said conduit distal end inflation segment, said expandable member being inflatable to a predetermined diameter; c. a seal consisting of an elastomeric material continuously and adhereingly disposed in said conduit central lumen along a predetermined segment at said proximal end thereof, said seal permitting ingress and egress of fluid to and from said conduit lumen via a syringe; and d. a fixation member having a base portion for contact with the patient body and means to engage said conduit until the patient body aperture is closed.
