International Classification:

A61F 2/24

Abstract:

Expandable docking stations for docking an expandable valve can include a valve seat, one or more sealing portions, and/or one or more retaining portions. The valve seat can include radiopaque markers affixed to a frame or an impermeable member. The radiopaque markers can indicate a deployment location of the valve. The docking stations can be deployed from a catheter including one or more radiopaque markers. Relative positioning of two or more radiopaque markers can provide an indication of the amount of deployment of the docking station.

International Classification:

A61M 25/00
A61M 25/10

Abstract:

A balloon catheter for use with a guidewire includes an elongated, tubular shaft extending in a longitudinal direction, said shaft having a proximal end and a distal end. An inflatable balloon is connected to the distal end of the shaft, the balloon including a working surface. A radiopaque identifier is provided for identifying the working surface. A receiver adjacent the proximal end of the shaft is adapted for allowing the shaft to move relative to the receiver in at least the longitudinal direction.

International Classification:

A61M 25/10

Abstract:

A balloon catheter adapted for use with a guidewire includes an elongated, tubular shaft extending in a longitudinal direction, said shaft having a proximal end and a distal end. An inflatable balloon is supported along the distal end of the shaft, the balloon when inflated including first and second spaced ends and a working surface between the ends. An insert located within the interior compartment of the balloon includes at least a radiopaque portion separate from the shaft. Related methods are also disclosed.

Appl. No.:

16/278214

Inventors:

- MURRAY HILL NJ, US
ANDREW SCHAFFER - Gilbert AZ, US

International Classification:

A61M 25/10

Abstract:

An inflatable balloon is provided. The balloon includes a central lumen open at both ends of the balloon and connected to a gap formed in one sidewall of the balloon. This arrangement may provide the balloon with a generally C-shaped profile with the open central lumen within the balloon along a center axis thereof, such as to allow for perfusion. The balloon may also include an inflation port offset from a central axis and a shaft including an inflation lumen connected to the inflation port. A sheath may also be provided with a window through which the balloon may project in use.

Mark D. Mendillo - Mission Viejo CA, US

International Classification:

A61M 5/168
F16K 7/10

Abstract:

A flow rate control device having features for selectively controlling the flow rate of a fluid over a continuous range of flow rates is provided. In particular, a flow rate control device including an inflatable flow restrictor is provided, where the flow restrictor is selectively inflatable to occlude a flow path of a fluid to thereby control the flow rate of the fluid. A flow rate control mechanism comprising a flow restrictor also is provided, the flow restrictor having an inflatable balloon for occluding a flow path of a fluid to selectively control the flow rate of the fluid.
