Abstract: Aspects of the disclosure include sizing catheters and methods for determining the size and other physical parameters of an internal orifice or lumen. Embodiments include a sizing catheter assembly having a handle assembly and a catheter assembly including at least one catheter extending from the handle assembly. The catheter assembly also includes at least two sizers, which can be adjustably spaced from each other. Each of the sizers are configured to conform to respective portions of a lumen of a patient's anatomy. The sizing catheter is configured such that the sizers are configured to specify or determine first and second dimensions of the lumen and also distance between the sizers. The sizers can include valve leaflets or the sizing catheter can include a temporary valve. Additional aspects include software/methods of assessing and determining an appropriate implantable device that can include assessing the biomechanical interaction between the device and the anatomy.

Abstract: A stent and a method for manufacturing a stent are provided. The stent includes a first ring having a plurality of peaks and a plurality of valleys, a second ring having a plurality of peaks and a plurality of valleys, and a connector that connects one of the peaks of the first ring to one of the valleys of the second ring. The connected peak of the first ring includes a deformed portion that extends towards the connected valley of the second ring. The method includes forming a first ring having a plurality of peaks and a plurality of valleys, forming a second ring having a plurality of peaks and a plurality of valleys, deforming a portion of at least one of the peaks of the first ring, and connecting the deformed portion of the peak of the first ring to one of the valleys of the second ring.

Abstract: A balloon catheter includes a balloon coupled to a shaft. The shaft includes a proximal perfusion portion disposed proximal of the balloon and a distal perfusion portion disposed distal of the balloon. The proximal and distal perfusion portions each are formed by a respective plurality of wire members woven together to form a respective proximal and distal braided shafts. The plurality of wire members are woven together such that a plurality of perfusion openings are formed between the wire members. The plurality of perfusion openings extend from an outer surface of the respective proximal or distal braided shaft to a lumen of the respective proximal or distal braided shaft. A perfusion lumen extends between the proximal perfusion portion and the distal perfusion portion.

Abstract: In some examples, an introducer apparatus includes an outer elongated member defining a lumen extending therethrough, the lumen having a lumen dimension in cross-section, and a dilator configured to be received within the lumen of the outer elongated member, the dilator may comprise a proximal section, a distal section comprising a distal end of the dilator, and an intermediate section disposed between the proximal section and the tapered distal section. In some examples, the intermediate section may define a through-opening that configures the intermediate section to be collapsible from an expanded configuration to a collapsed configuration. In the collapsed configuration, the intermediate section may have a first dilator dimension in cross-section that is less than a second dilator dimension in cross-section when the intermediate section is in the expanded configuration.
