Abstract: Balloon catheter and methods for making and using balloon catheters are disclosed. An example balloon catheter may include a proximal shaft. A midshaft may be attached to the proximal shaft. The midshaft may have an outer wall. A distal shaft may be attached to the midshaft. A balloon may be coupled to the distal shaft. An inflation lumen may be defined that extends from the proximal shaft, through the midshaft, and into the distal shaft. The inflation lumen may be in fluid communication with the balloon. A core wire may be disposed within the inflation lumen and may be attached to the midshaft.

Abstract: An elongate shaft of a medical catheter including a thermoset polymeric tubular member including a skived distal portion. The skived distal portion includes a distally extending trough having a convex surface and a concave surface. A thermoplastic tubular sleeve may be positioned over at least a portion of the skived distal portion of the thermoset polymeric tubular member. In some instances, the thermoplastic tubular sleeve includes a crescent-shaped tubular portion defining a crescent-shaped lumen. The trough of the skived distal portion may extend through the crescent-shaped lumen. The thermoplastic tubular sleeve is thermally bonded to the inner and outer tubular members of a distal section of the elongate shaft at a guidewire port joint.

Abstract: A needle device for obtaining a tissue sample includes a distal member extending longitudinally from a proximal end to a distal end and including a distal channel extending longitudinally therethrough, the distal member formed of a first material selected to permit flexing of the distal member, a proximal member extending longitudinally from a proximal end to a distal end and including a proximal channel extending longitudinally therethrough, the proximal member formed of a second material selected to provide axial and torsional strength therealong in combination with a coupler for connecting the distal member and the proximal member, the coupler extending longitudinally from a proximal end configured to engage the distal end of the proximal member to a distal end configured to engage the proximal end of the distal member.

Abstract: Balloon catheters, coil assemblies, and methods for making the same. An example balloon catheter may include a coil assembly. The coil assembly may include a coil, a coating disposed on the coil, and a sheath disposed over the coil and the coating. A guidewire lumen may be defined by the coil assembly. An outer tube disposed over at least a portion of the coil assembly. A balloon may be coupled to the outer tube. An inflation lumen may be defined between the coil assembly and the outer tube.

Abstract: This document provides medical device systems and methods for obtaining tissue samples. For example, this document provides medical device systems and methods for transbronchial needle biopsy tissue acquisition. In some cases, a needle biopsy system includes an actuator device, an outer needle with a lumen therethrough, and an inner needle at least partially disposed within the lumen. The outer needle can extend distally from the actuator device. A distal tip of the inner needle can be capable of being fully disposed within the lumen. The inner needle can extend distally from the actuator device. The actuator device can be configured to translate the outer needle proximally and distally. The actuator device can be configured to translate the inner needle proximally and distally independently of the outer needle.
