Abstract: The present disclosure relates to the field of embolic coils. More specifically, the present disclosure relates to systems and methods for actively releasing an embolic coil from a delivery device into a body lumen of a patient. Delivery systems of the present disclosure may allow an embolic coil to be advanced external to the distal end of a delivery catheter without being automatically released, thereby allowing the embolic coil to be repositioned prior to deployment.

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 expandable medical balloon comprising an inner layer formed of a polymer material having a first flexural modulus, an intermediate layer formed of a material having a second flexural and an outer layer formed of a material having a third flexural modulus, wherein the flexural modulus of the inner layer and outer layer is 50,000 psi to about 80,000 psi, the flexural modulus of the intermediate layer is about 130,000 to about 230,000 psi and the calculated burst strength of the balloon determined on a 90 degree bend in the balloon is about 35,000 psi or higher.
