Abstract
A ready-to-use urinary catheter assembly (20) includes a catheter (26) comprising a shaft (28) having a proximal insertion end (30) and a distal end (32) spaced from the proximal insertion end. The assembly also includes a protective sleeve (54) including a protective sleeve tip (36) being configured to cover the proximal insertion end of the catheter shaft as the proximal insertion end of the catheter shaft is inserted into a distal portion of the urethra. The proximal insertion end (30) of the catheter shaft (28) is advanced proximally to rupture the protective sleeve tip (36) and to be advanced through the remainder of the urethra.
Claims20
A urinary catheter assembly, comprising:
- a catheter including a catheter shaft having a proximal insertion end and a distal end remote from the proximal insertion end, the proximal insertion end of the catheter shaft including a closed proximal terminal end;
- a protective sleeve extending over an outer surface of the catheter shaft from the closed proximal terminal end to the distal end, wherein the protective sleeve has a proximal end portion defining a protective sleeve tip covering the proximal insertion end of the catheter shaft and having a rupturable proximal end confining the proximal insertion end of the catheter shaft within the protective sleeve tip;
- the protective sleeve and sleeve tip being of a single continuous unitary construction wherein the protective sleeve and sleeve tip are formed from the same thin, flexible material, wherein the proximal insertion end of the catheter shaft is confined within the protective sleeve tip and the thin, flexible material of the protective sleeve tip conforms to and is supported by the proximal insertion end of the catheter shaft to insert the protective sleeve tip into the urethral opening;
- and
- the proximal insertion end of the catheter shaft being proximally advanceable to rupture the proximal end of the protective sleeve tip to advance the catheter through the urethra.
A urinary catheter assembly, comprising:
- a catheter including a catheter shaft having a proximal insertion end and a distal end remote from the proximal insertion end, the proximal insertion end of the catheter shaft including a closed proximal terminal end;
- a protective sleeve of unitary construction extending over an outer surface of the catheter shaft from the closed proximal terminal end to the distal end, wherein the protective sleeve has a proximal end portion defining a protective sleeve tip, the protective sleeve and sleeve tip being of a single continuous unitary construction wherein the protective sleeve and sleeve tip are formed from the same thin, flexible material, the protective sleeve tip covering the proximal insertion end of the catheter shaft and having a rupturable proximal end confining the proximal insertion end of the catheter shaft, the protective sleeve extending from the proximal insertion end of the catheter shaft to a location at or near the distal end of the catheter shaft;
- and
- the protective sleeve tip conforming to the proximal insertion end of the catheter shaft and the proximal insertion end of the catheter shaft supporting the thin, flexible material of the protective sleeve tip for inserting the protective sleeve tip into a distal portion of the urethra.
