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: Vessel wound closure systems and method for sealing a puncture wound in a target vessel, such as those puncture wounds that occur from prior interventional procedures. A sealing member is deployed intravascularly into the target vessel, and an anchor member is deployed extravacularly of the target vessel. The sealing member and the anchor member are connected by a suture that may be drawn to tighten the sealing member and the anchor member relative to one another in order to effect the seal of the puncture wound. After tightening, the suture is secured to maintain the sealing member and the anchor member relative to one another in order to maintain the seal. Preferably, the anchor member, the suture and the sealing member are comprised of biocompatible, bioresorbable materials that are absorbed into the body after the sealing of the puncture wound has been achieved.

Abstract: A system for forming a suture connector in situ includes a suture connector placement device having a handle, an outer shaft, an intermediate shaft, and a push rod, and a suture connector having a sleeve and a plug. The intermediate shaft is slidingly disposed through a lumen of the outer shaft, and the push rod is slidingly disposed through a lumen of the intermediate shaft. When the suture connector is in a loaded configuration within the suture connector placement device, the sleeve is radially disposed over the intermediate shaft and the plug is positioned proximal to the sleeve within the lumen of the intermediate shaft. Distal advancement of the push rod moves the plug into the sleeve and proximal retraction of the intermediate shaft releases the resilient sleeve onto the plug, thereby securing two suture portions between the sleeve and the plug. The system is then utilized to trim the suture portions.
