Abstract
A medical device including a locking mechanism and a method including activating the locking mechanism are described herein. The medical device includes distal and proximal disc portions and a locking mechanism. The locking mechanism is configured to pull and maintain the distal and proximal disc portions toward each other when the medical device is deployed in an expanded configuration.
Claims20
A medical device for treating a target site, the medical device comprising:
- a tubular member comprising a proximal disc portion at a proximal end, a distal disc portion at a distal end, and a waist member extending between the proximal disc portion and the distal disc portion, wherein the tubular member has an expanded configuration when deployed at the target site and a reduced configuration for delivery to the target site;
- and
- a locking mechanism comprising a distal locking portion attached to the distal disc portion and a proximal locking portion attached to the proximal disc portion, wherein the distal locking portion and the proximal locking portion are configured to be coupled together when the medical device is in the expanded configuration,
- wherein the locking mechanism is a passive locking mechanism.
A medical device for treating a target site, the medical device comprising:
- a tubular member comprising a proximal disc portion at a proximal end, a distal disc portion at a distal end, and a waist member extending between the proximal disc portion and the distal disc portion, wherein the tubular member has an expanded configuration when deployed at the target site and a reduced configuration for delivery to the target site;
- and
- a locking mechanism comprising at least one coupling element attached to both the distal disc portion and the proximal disc portion, wherein the at least one coupling element is a spring that internally extends from the distal disc portion to the proximal disc portion in a criss-cross pattern such that the distal disc portion and the proximal disc portion are configured to pull toward each other when the tubular member is in the expanded configuration.
