Delivery system for fixation device, including guide catheter with proximal end portion having proximal end port, distal end portion having distal end port, and inner surface defining inner lumen extending in fluid communication between proximal end port and distal end port. Delivery catheter extending through the inner lumen to define annular space between outer surface of the delivery catheter and inner surface of the guide catheter. A pressure sensor proximate the proximal end portion in fluid communication with the annual space to monitor fluid pressure. The distal end portion of the guide catheter includes flow passages in fluid communication between an exterior of the distal end portion and the annular space.

Systems and methods for intra-procedural cardiac pressure monitoring

An intravascular device includes a shaft having a body defining a major lumen and a plurality of minor lumen. The minor lumens are spaced about the major lumen. The major lumen and the plurality of minor lumen extend from a proximal end of the body to a distal end of the body. One or more wires may extend through the major lumen and/or minor lumen.

Delivery catheter systems, methods, and devices

Methods and systems for controlling the moisture content of biodegradable and bioresorbable polymer resin during extrusion above a lower limit that allows for plasticization of the polymer resin melt and below an upper limit to reduce or prevent molecular weight loss are disclosed. Methods are further disclosed involving plasticization of a polymer resin for feeding into an extruder with carbon dioxide and freon.

Controlling moisture in and plasticization of bioresorbable polymer for melt processing

Methods of fabricating a polymer scaffold with increased radial strength including steps of elongation or strain of a biaxially oriented tube and annealing or thermal processing of the strained tube at a constant strain are disclosed. The steps of elongation and thermal processing increase axial direction chain orientation and lamellar crystal growth, increase radial strength, and decrease the thickness of the tube. The method allows fabrication of a scaffold with thinner struts which provide sufficient radial strength.

Method to increase radial strength of a bioresorbable scaffold

A polymer tube is processed using a solid phase process for improving mechanical characteristics of the tube, including radial strength and stiffness. The tube is made into a scaffold possessing improved mechanical and use characteristics, such as a reduced crimped profile and improved deliverability.

Methods for solid phase processing of tubes and medical devices made from the processed tubes

Bioresorbable polymer vascular scaffolds made of combinations of polylactide and polycaprolactone having a high molecular weight polymer, thin struts in a selected range and sufficient radial strength to support a vessel upon deployment. The scaffolds have degradation behavior of molecular weight, radial strength, and mass that are conducive to healing of a vessel including providing patency to a vessel, reduction of radial strength, breaking up, and resorbing to allow return of the vessel to a natural state.

High molecular weight polylactide and polycaprolactone copolymer and blends for bioresorbable vascular scaffolds

A stent crimping tool insert comprises a core body configured for insertion into and removal from within a crimping chamber of a stent crimping tool. The core body has a core surface configured to withstand a compressive force without a reduction in diameter of the core surface.

Stent crimping tool insert, system, and method

A medical device implantable within a peripheral vessel of the body composed of a bioresorbable polymer is disclosed. The device has a high resistance to fracture, is very flexible, and has a high crush recovery when subjected to crushing, axial, or torsional forces.

Drug delivery device for peripheral artery disease

A medical device includes a polymer scaffold crimped to a balloon. The balloon is formed with between 6 and 15 pleats to provide a uniform expansion of the scaffold when the balloon is inflated. Also provided are methods for crimping a scaffold to a multi-pleated balloon and methods for making a multi-pleated balloon.

Polymer scaffold with multi-pleated balloon

Methods to expand polymer tubing with desirable or optimum morphology and mechanical properties for stem manufacture and fabrication of a stent therefrom are disclosed.

Controlling crystalline morphology of a bioabsorbable stent

An apparatus includes a piezoelectric print head capable of ejecting a droplet of a coating substance towards a stent strut, a sensor capable of sensing a parameter of the droplet, and a controller, communicatively coupled to the print head and the sensor, capable of determining if the parameter of the droplet meets a requirement. A method includes ejecting a droplet of a coating substance towards a stent strut with a piezoelectric print head, sensing a parameter of the droplet, and determining whether the parameter of the droplet meets a requirement.
