Filed:

Apr 30, 2018

Appl. No.:

15/966173

Inventors:

- Carpinteria CA, US
Anthony Appling - Crestwood KY, US

International Classification:

A61M 39/06
A61B 1/018
A61B 1/00

Abstract:

A medical valve assembly includes a tube extending between a first and second tube end along an axis, and a plunger plate extends radially from the second tube end. A valve housing surrounds the tube and includes a radially inwardly extending flange. A compression member is biased against the plunger plate and compresses an elastomeric seal from a non-compressed condition to a compressed condition to establish a sealed condition of the medical valve assembly. An inner surface of the elastomeric seal in the non-compressed condition has a plurality of planar portions and a plurality of radiused portions, with adjacent planar portions interconnected with one of the radiused portions to improve a closure of the elastomeric seal during compression. The inner surface preferably includes three planar portions and three radiused portions to define a generally triangular-shaped inner surface as viewed in cross section in the non-compressed condition.

International Classification:

A61M 39/06

Abstract:

A medical valve assembly includes a tube extending between proximal and distal tube ends. A plunger plate extends radially from the distal tube end, and a valve housing surrounds the tube and extends between proximal and distal valve housing ends. The valve housing includes a flange extending radially inwardly from the distal valve housing end and disposed in spaced relationship with the plunger plate to define a distance dimension D extending therebetween. An elastomeric seal is compressed between the plunger plate and the flange to establish a closed condition of the medical valve assembly. The elastomeric seal axially moves one of the valve housing and the tube relative to the other when a medical device is inserted into the medical valve assembly to automatically increase the distance dimension and establish an open and sealed condition of the medical valve assembly with the inserted medical valve.

Abstract:

An expandable introducer assembly includes a dilator subassembly extending from a proximal end to a distal end. The dilator subassembly includes a dilator having an insertion portion disposed adjacent the distal end, an expansion portion disposed adjacent the distal end, and a tapered transition portion disposed between the insertion and expansion portions. The dilator subassembly includes a distal sheath disposed in overlaying relationship with the insertion portion of the dilator. An introducer subassembly is disposed in coaxial relationship with the expansion portion of the dilator, and includes a valve disposed adjacent the proximal end and an introducer sheath extending from the valve in overlaying relationship with the expansion portion of the dilator. An expandable sheath subassembly is releasably interlocked with the dilator subassembly and includes an expandable sheath disposed in overlaying relationship with the tapered transition portion and in nested relationship between the insertion portion and the distal sheath.
