Abstract
Expandable access sheaths and methods for use thereof are disclosed. The access sheath may have an expandable element and flexible membrane. The access sheath may be configured to move between a non-expanded configuration and an expanded configuration. The access sheath may be biased towards the non-expanded configuration.
Claims20
A dilator access sheath, comprising:
- a flexible sheath having a proximal end, a distal end, and a lumen extending between the proximal end and the distal end, the flexible sheath having an expandable element and a flexible membrane and wherein the flexible sheath is designed to move between a non-expanded configuration and an expanded configuration;
- and
- a hub coupled to the proximal end of the flexible sheath;
- and
- wherein the flexible sheath is biased towards the non-expanded configuration.
2 more elements
A dilator access sheath assembly, comprising:
- an access sheath having a proximal end, a distal end, and a lumen extending between the proximal end and the distal end, the access sheath having an expandable element and a flexible membrane and the access sheath configured to move between a non-expanded configuration and an expanded configuration;
- a dilator having a proximal end and a distal end, the dilator disposed within the lumen of the access sheath and configured to be removable therefrom;
- a first hub affixed to the proximal end of the dilator;
- and
- a second hub affixed to the proximal end of the access sheath;
- and
- wherein the access sheath is biased towards the non-expanded configuration.
4 more elements
A method, comprising:
- inserting a dilator and access sheath assembly into a body lumen, the access sheath having a non-expanded configuration and an expanded configuration;
- advancing the dilator and access sheath assembly to a required destination;
- removing the dilator from the body lumen;
- and
- advancing a device through a lumen of the access sheath;
- wherein the dilator dilates the body lumen to a first diameter and advancing the device through the lumen of the access sheath moves the access sheath to the expanded configuration and dilates the body lumen to a second diameter larger than the first diameter.
