Mechanical damping structure
TLDR
A body adapted to absorb energy, especially a shock or force damper, consists of a sponge or foam metal matrix with pores and, preferably, a filler of vermiculite or perlite in an expanded state.Abstract:
A body adapted to absorb energy, especially a shock or force damper, consists of a sponge or foam metal matrix with pores and, preferably, a filler of vermiculite or perlite in an expanded state. The body is predeformed through 5 to 35 percent of its original volume before it is employed as a shock or force damper.read more

Ultrasound catheter apparatus
TL;DR: In this paper, an absorber member is disposed on or around the ultrasound transmission wire at a location adjacent the sonic connector of the catheter to absorb heat, vibrations, and/or the like from the ultrasound transducer.

Connector for securing ultrasound catheter to transducer
Henry Nita,Martinos Tran +1 more
TL;DR: In this article, an ultrasound transducer with a horn and a catheter knob coupled to the distal end of the transducers has been described, and a nesting piece that is retained inside the proximal bore of the knob is moved from a first position where the sonic connector is received inside the nesting piece to a second position when ultrasound energy is being propagated through the ultrasound transmission member.

Steerable ultrasound catheter
Henry Nita,Jeff Sarge +1 more
TL;DR: In this paper, the authors describe an elongate flexible catheter body with one or more lumens, an ultrasound transmission member extending longitudinally through the catheter lumen and a distal head coupled with the transmission member.
Patent
Vibration damped apparatus
Scott Inman,Mitchell K. Enright +1 more
TL;DR: In this article, a damping mass is formed from a elastic material throughout which a plurality of sub-masses are distributed, relatively positioned so that the damping has different moduli of elasticity in tension and compression, so as to quickly dampen a broad frequency range of vibrations in the vibrating member.
