20170239447 · 2017-08-24 ·

A neurovascular catheter extension segment is provided, such as for distal neurovascular access or aspiration. The neurovascular catheter extension segment includes 1) an elongate flexible control wire having a proximal end and a distal end and 2) a tubular extension segment having a side wall defining a central lumen carried by the distal end of the control wire. The side wall of the tubular extension segment includes a tubular inner liner, a tie layer separated from the lumen by the inner liner, a helical coil surrounding the tie layer, and an outer jacket surrounding the helical coil. The extension segment may be introduced into the proximal end of a neurovascular catheter and advanced distally to extend beyond the catheter and thereby extend the reach of the catheter.

09814476 · 2017-11-14 · ·

A valvuloplasty system includes a balloon adapted to be placed adjacent leaflets of a valve. The balloon is inflatable with a liquid. The system further includes a shock wave generator within the balloon that produces shock waves that propagate through the liquid for impinging upon the valve. The shock wave generator is moveable within the balloon to vary shock wave impingement on the valve.

SPECTROSCOPIC TISSUE IDENTIFICATION FOR BALLOON INTRAVASCULAR LITHOTRIPSY GUIDANCE

A catheter system (100) for placement within a treatment site (106) at a vessel wall (208A) or a heart valve includes an energy source (124), a balloon (104), an energy guide (122A), and a tissue identification system (142). The energy source (124) generates energy. The balloon (104) is positionable substantially adjacent to the treatment site (106). The balloon (104) has a balloon wall (130) that defines a balloon interior (146). The balloon (104) is configured to retain a balloon fluid (132) within the balloon interior (146). The energy guide (122A) is configured to receive energy from the energy source (124) and guide the energy into the balloon interior (146) so that plasma is formed in the balloon fluid (132) within the balloon interior (146). The tissue identification system (142) is configured to spectroscopically analyze tissue within the treatment site (106). A method for treating a treatment site (106) within or adjacent to a vessel wall (208A) or a heart valve can utilize any of the catheter systems (100) described herein.

DEVICES FOR TREATING CALCIFIED HEART VALVES

A balloon device for treating a calcified structure of a body tissue, including an elongated body extending between a proximal end and a distal end and having at least one lumen extending along at least a portion thereof and defining a fluid path, and at least one inflatable balloon secured to the elongated body and fluidly connected to the at least one lumen, with the at least one lumen being fluidly connectable to a fluid source for selectively inflating and deflating the at least one inflatable balloon, and with the at least one inflatable balloon, when being inflated, is positioned in close proximity to the calcified structure and vibrating, mechanical vibrations of the at least one inflatable balloon causes destructuration of the calcified structure.

Connector for surgical handpiece

A surgical handpiece nosecone having an end overmold portion and/or an internal overmold portion. The end overmold portion is located at an end of the nosecone and compressed between the surgical handpiece housing and nosecone.
