Abstract: An effective blood vessel diameter at a deployment site within a blood vessel may be determined using a measurement apparatus that includes an inflatable balloon. The measurement apparatus may be advanced to the deployment site and the inflatable balloon may be inflated in order to temporarily reshape the blood vessel at the deployment site to a more circular cross-sectional profile. A measurement pertaining to the effective vessel diameter may be obtained while the inflatable balloon remains inflated. The measurement may be obtained using an ultrasound catheter. The measurement may be obtained using fluoroscopy, for example.

Abstract: An effective vessel diameter of a blood vessel at a deployment site may be determined using a measurement apparatus that includes an expandable element that is moveable between a collapsed configuration for advancement and an expanded configuration for measurement. The measurement apparatus may be advanced to the deployment site with the expandable element in its collapsed configuration. The expandable element may be caused to expand from its collapsed configuration to its expanded configuration and one or more measurements pertaining to the expandable element in its expanded configuration may be obtained. The one or more measurements may be used to determine an effective vessel diameter at the deployment site.

Abstract: Stent delivery systems including a deployment sheath for the stent, and an anti-catch member positionable adjacent to a proximal end of the deployment sheath and designed to allow the proximal end of the deployment sheath to be passed through the stent without catching on the stent.

Abstract: Stent delivery systems and methods for making and using stent delivery systems are disclosed. An example stent delivery system may include an inner member having a stent receiving region, a stent disposed along the stent receiving region, a deployment sheath axially slidable relative to the inner member, the deployment sheath having a proximal end region, a handle coupled to the deployment sheath, a rod coupled to the handle, the rod having a distal end region, a proximal end region and a first threaded portion extending from the distal end region to the proximal end region and a coupling member configured to couple the rod to the deployment sheath, the coupling member having an engagement portion. Additionally, the first threaded portion of the rod is designed to engage the engagement portion of coupling member and rotation of the rod is designed to translate the coupling member along the rod.
