Abstract
Devices and methods for providing fluid to a lumen of a guide catheter with a fluid reservoir fluidly coupled to the lumen, such that pressure within the lumen is maintained at a desired level, are disclosed. As one example, a delivery apparatus can include a handle, a shaft extending within and distally from the handle and having a main lumen, and a reservoir fluidly coupled to the main lumen. The reservoir is filled with fluid and has an adjustable fluid volume, and the reservoir is configured to passively supply fluid to the main lumen based on a fluid pressure in the main lumen.
Claims20
A delivery apparatus comprising:
- a handle;
- a shaft extending within and distally from the handle and having a main lumen;
- and
- a reservoir fluidly coupled to the main lumen, wherein the reservoir is filled with fluid and has an adjustable fluid volume, and wherein the reservoir is configured to passively supply fluid to the main lumen based on a fluid pressure in the main lumen.
A guide sheath comprising:
- a handle comprising:
- a housing;
- and
- a flush port coupled to the housing;
- a reservoir fluidly coupled to the flush port and disposed external to the housing, wherein the reservoir is filled with fluid and has an adjustable volume;
- and
- a shaft extending within and distally from the handle and having a main lumen that extends within the housing, wherein the main lumen is fluidly coupled to the reservoir by the flush port, and wherein the reservoir is configured to passively supply fluid to the main lumen based on a fluid pressure in the main lumen.
A method for implanting a prosthetic medical device, comprising:
- inserting a shaft of a guide catheter into a vessel of a patient, the shaft having a main lumen and extending from within and distal to a handle of the guide catheter;
- and
- inserting a distal end portion of a first implant catheter into a proximal end of the guide catheter and advancing the distal end portion of the first implant catheter through the main lumen of the guide catheter toward a target implantation site for a prosthetic medical device mounted on the distal end portion of the first implant catheter,
- wherein, as the distal end portion of the first implant catheter is advanced through the main lumen, fluid is pulled passively from a fluid reservoir into the main lumen such that a volume of the fluid reservoir decreases.
