Devices for delivering energy and related methods of use
First Claim
1. A medical device, comprising:
- a shaft having a shaft lumen extending at least partially between a proximal end and a distal end of the shaft;
a plurality of legs proximate a distal portion of the shaft;
a distal end piece coupled to each of the plurality of legs and located distally to the distal end of the shaft;
an actuating member coupled to the distal end piece and extending between the plurality of legs and through the shaft lumen, wherein reciprocal movement of the actuating member is configured to reversibly move the plurality of legs from a first position to a second position; and
a stopping member coupled to the actuating member and at least a portion of the stopping member is disposed within the distal end piece, the stopping member defines a stopping member lumen configured to receive a portion of the actuating member, wherein proximal movement of the actuating member compresses the stopping member, and compression of the stopping member limits the proximal movement of the actuating member and radial expansion of the plurality of legs.

Abstract
A medical device is disclosed. The medical device may include an elongate member having a lumen extending at least partially between a proximal end and a distal end of the elongate member. The medical device may also include a plurality of legs coupled to a distal portion of the elongate member, and a distal end piece connected to each of the plurality of legs and located distally to the distal end of the elongate member. The medical device may also include an actuating member coupled to the distal end piece and extending between the plurality of legs and through the lumen. The reciprocal movement of the actuating member may be configured to reversibly move the plurality of legs from a first position to a second position. The medical device may also include a stopping member coupled to the actuating member and configured to limit a movement of the actuating member.

12. A medical device, comprising:
-
a shaft having a lumen extending at least partially between a proximal end and a distal end of the shaft; a plurality of legs proximate a distal portion of the shaft; a distal end piece coupled to each of the plurality of legs and located distally to the distal end of the shaft; an actuating member coupled to the distal end piece and extending between the plurality of legs and through the lumen, wherein reciprocal movement of the actuating member is configured to reversibly move the plurality of legs from a first, radially-collapsed, position to a second, radially expanded, position;
wherein the actuating member includes a first portion having a proximal end and a distal end, and a second portion having a proximal end and a distal end, the proximal end of the second portion being distal to the distal end of the first portion; anda stopping member coupled to the actuating member and configured to limit a movement of the actuating member, wherein the stopping member is disposed proximal to the plurality of legs and the stopping member also is disposed between the distal end of the first portion and the proximal end of the second portion, and; when the plurality of legs are in the first position, application of a proximal force to the actuating member below a threshold amount moves the plurality of legs toward the second position; and after the plurality of legs have been moved from the first position toward the second position, application of a proximal force to the actuating member above the threshold amount expands the stopping member to prevent further radial expansion of the plurality of legs. - View Dependent Claims (13, 14, 15)

16. A medical device, comprising:
-
a shaft having a lumen extending between a proximal end and a distal end of the shaft; a plurality of legs extending from the distal end of the shaft, wherein; at least one of the legs includes an electrode for delivering energy; and wherein each of the plurality of legs includes a distal end; a distal end piece coupled to the distal end of each of the plurality of legs; an actuating member coupled to the distal end piece and extending between the plurality of legs and through the lumen, the actuating member configured to reversibly move the plurality of legs from a first position to a second position, wherein; the plurality of legs move from the first position to the second position when a proximal force is applied to the actuating member; and the plurality of legs move from the second position to the first position when the proximal force is released; and a stopping member coupled to the actuating member and at least a portion of the stopping member is disposed within the distal end piece, the stopping member defines a stopping member lumen configured to receive a portion of the actuating member, wherein compression of the stopping member limits radial expansion of the plurality of legs.
