Patent number: 11911579Abstract: A catheter pump is disclosed. The catheter pump can include an impeller and a catheter body having a lumen in which waste fluid flows proximally therethrough during operation of the catheter pump. The catheter pump can also include a drive shaft disposed inside the catheter body. A motor assembly can include a chamber. The motor assembly can include a rotor disposed in the at least a portion of the chamber, the rotor mechanically coupled with a proximal portion of the drive shaft such that rotation of the rotor causes the drive shaft to rotate, the rotor including a longitudinal rotor lumen therethrough. The motor assembly can also comprise a stator assembly disposed about the rotor. During operation of the catheter pump, the waste fluid flows from the lumen into the chamber such that at least a portion of the waste fluid flows proximally through the longitudinal rotor lumen.Type: GrantFiled: November 30, 2020Date of Patent: February 27, 2024Assignee: TC1 LLCInventors: Adam R. Tanner, Paul F. Muller, Alan Schenck, Michael R. Butler, Todd Jenkins

Patent number: 11547845Abstract: Various embodiments of a system for priming a catheter assembly are disclosed herein. For example, the system can include a catheter assembly including an elongate body and an operative device coupled thereto. The system can also include a priming vessel configured to receive insertion of the operative device therein. The priming vessel can include a proximal portion secured to the distal portion of the elongate body such that the elongate body is in fluid communication with the priming vessel. The priming vessel can also include a distal end through which air is expelled when a fluid is channeled through the elongate body and into the priming vessel to expel air from within the catheter assembly.Type: GrantFiled: April 15, 2020Date of Patent: January 10, 2023Assignee: TC1 LLCInventors: Alan Schenck, Michael L.

Patent number: 8515553Abstract: Apparatus and methods for predictively controlling the temperature of a coolant delivered to a treatment apparatus configured to non-invasively treat a patient's tissue with doses of electromagnetic energy. The treatment apparatus includes a closed-loop cooling system connected with an energy delivery device used to deliver the electromagnetic energy to the patient's tissue. Coolant is pumped from a reservoir to the energy delivery device in the closed-loop cooling system. The control temperature of the coolant in the reservoir is adjusted based upon the specific room air temperature. This predictive adjustment promotes better control over the coolant temperature at the energy delivery device by lessening the effects of heat gain in transit from the reservoir to the energy delivery device.Type: GrantFiled: April 28, 2008Date of Patent: August 20, 2013Assignee: Thermage, Inc.Inventor: Alan Schenck
