20120172656 | PERCUTANEOUS HEART PUMP - A heart pump and a catheter assembly therefor are provided that include a flexible catheter body having a proximal end and a distal end, the catheter body having a plurality of lumens therethrough. The catheter body can be sufficiently flexible to extend from a peripheral access to a patient's heart. The catheter assembly can also include an impeller assembly having an impeller and a housing. The impeller assembly can be coupled with the flexible catheter body such that a tensile force applied to opposite ends of the catheter assembly enhances the security of the connection between the catheter body and the impeller assembly. | 07-05-2012 |
20130303969 | SHEATH SYSTEM FOR CATHETER PUMP - A catheter pump assembly is provided that includes an elongate polymeric catheter body, a cannula, and a tubular interface. The elongate polymeric catheter body has a proximal end and a distal end. The cannula has an expandable portion disposed distally of the elongate polymeric catheter body. The cannula can also have another tubular portion that is proximal to the distal portion. The tubular interface has an outer surface configured to be joined to the tubular portion of the cannula and an inner surface. The inner surface is disposed over the distal end of the elongate polymeric catheter body. The tubular interface has a plurality of transverse channels extending outward from the inner surface of the tubular interface. An outer surface of the elongate polymeric catheter body projects into the transverse channels to mechanically integrate the elongate polymeric catheter body with the tubular interface. | 11-14-2013 |
20130303970 | DISTAL BEARING SUPPORT - In various embodiments, a catheter pump is disclosed herein. The catheter pump can include an elongated catheter body having a distal portion including an expandable cannula having an inlet and an outlet. The expandable cannula can have a delivery profile and an operational profile larger than the delivery profile. An impeller assembly can include an impeller shaft, and an impeller body can include one or more blades. The impeller blades can draw blood into the cannula when rotated. Further, an expandable support can have a mounting portion disposed on the impeller shaft distal of the impeller body and a cannula contact portion for reducing a change in tip gap due to bending of the cannula. The cannula contact portion can be disposed distal of the mounting portion. | 11-14-2013 |
20140010686 | MOTOR ASSEMBLY FOR CATHETER PUMP - A catheter pump is disclosed herein. The catheter pump can include a catheter assembly that comprises a drive shaft and an impeller coupled to a distal end of the drive shaft. A driven assembly can be coupled to a proximal end of the drive shaft within a driven assembly housing. The catheter pump can also include a drive system that comprises a motor and a drive magnet coupled to an output shaft of the motor. The drive system can include a drive assembly housing having at least one magnet therein. Further, a securement device can be configured to prevent disengagement of the driven assembly housing from the drive assembly housing during operation of the pump. | 01-09-2014 |
20140012065 | CATHETER PUMP - A catheter pump is provided that includes a rotatable impeller and an elongate cannula. The elongate cannula has a mesh that has a plurality of circumferential members disposed about the impeller. The elongate cannula has a plurality of axial connector extending between a proximal side of a distal circumferential member and a distal side of a proximal circumferential member. The circumferential members are radially self-expandable. The cannula is configured to minimize fracture within at least in the distal zone of the mesh as the elongated cannula moves into a sheathing device. | 01-09-2014 |
20140275725 | FLUID HANDLING SYSTEM - Various embodiments of a fluid handling system are disclosed herein. For example, the fluid handling system can include a catheter assembly and a console configured to control the operation of the catheter assembly. A removable interface member can be configured to provide fluid and electrical communication between the catheter assembly and the console. | 09-18-2014 |
20150290371 | CATHETER PUMP WITH ACCESS PORTS - A catheter pump is disclosed herein. The catheter pump can include an elongate catheter body and an impeller assembly coupled to a distal portion of the elongate catheter body. The impeller assembly can comprise an impeller configured to rotate during operation of the catheter pump. A tube can extend through at least portions of the elongate catheter body and the impeller assembly. The tube can extend distal the impeller and can be configured to remain in the portions of the elongate catheter body and the impeller assembly during operation of the catheter pump. | 10-15-2015 |
20150290372 | SENSORS FOR CATHETER PUMPS - Sensors for catheter pumps are disclosed herein. The catheter pump can include a catheter assembly comprising a catheter and a cannula coupled to a distal portion of the catheter. The cannula can have a proximal port for permitting the flow of blood therethrough. The catheter assembly can include a sensor to be disposed near the proximal port. A processing unit can be programmed to process a signal detected by the sensor. The processing unit can comprise a computer-readable set of rules to evaluate the signal to determine a position of the cannula relative to an aortic valve of a patient. | 10-15-2015 |
