Abstract
System for vascular draining comprising a cannula for use in medical applications, wherein the cannula comprises a plurality of flexible filaments, such that the cannula can be varied between a normal and a low-profile configuration, wherein the proximal cannula portion is formed by a sleeve, and a plug device comprising a first and a second section, wherein the second section is configured to be releasable positioned into the sleeve, wherein the plug device comprises at least one fastening member configured to establish a press fit and/or a twist and/or a clamp connection between the sleeve and the plug device, such that when the plug device engages the sleeve, the cannula is transferred from the normal to the low-profile configuration.
Claims15
System for vascular draining comprising
- a cannula (1), in particular for use in medical applications, with a distal cannula portion (2) and a proximal cannula portion (3), wherein the cannula (1) comprises a plurality of flexible filaments (4), such that the cannula (1) can be varied between a normal and a low-profile configuration, wherein the proximal cannula portion (3) is formed by a sleeve (5), and
- a plug device (6) comprising a first (7) and a second (8) section, wherein the second section (8) is configured to be releasable positioned into the sleeve (5) and the second section comprises an opening (9) to receive a proximal portion of an elongated member (10) and
- wherein the plug device (6) comprises at least one fastening member (11) configured to establish a press fit and/or a twist and/or a clamp connection between the sleeve (5) and the plug device (6), such that when the plug device (6) engages the sleeve (5), the cannula (1) is transferred from the normal to the low-profile configuration.
System according to any of the previous claims, wherein, in particular for the press fit connection, the fastening member (11) comprises a, in particular ring-shaped, protrusion (12).
System according to any of the previous claims, wherein, in particular for the twist connection, the sleeve (5) comprises a, in particular external, thread (13) and the fastening member (11) comprises a, in particular internal, thread (14), configured to rotatably engage with each other.
System according to any of the previous claims, wherein, in particular for the twist connection, the sleeve (5) comprises a protrusion (12) and the fastening member (11) comprises a slot (15), wherein the slot (15) is configured to accommodate the protrusion (12).
System according to any of the previous claims, wherein, in particular for the clamp connection, the sleeve 5 comprises a protrusion (12) and the plug device (6) comprises a clamp member (16), wherein the clamp member (16) comprises the fastening member (11), which is configured to engage with the protrusion (12) of the sleeve.
System according to any of the previous claims, wherein the sleeve (5) comprises a beveled proximal portion.
System according to any of the previous claims, wherein the second section (8) is at least partially tapered, in particular at least partially conically shaped.
System according to any of the previous claims, wherein the first (7) and the second (8) section are formed cylindrically and wherein the second section (8) has a smaller diameter than the first section (7).
Plug device for use in a, in particular medical, cannula, wherein the cannula (1) comprises a proximal cannula portion (3) formed by a sleeve (5), in particular by a support sleeve (17), and a plurality of flexible filaments (4), such that the cannula (1) can be varied between a normal and a low-profile configuration, the plug device (6) comprising
- a first (7) and a second (8) section, wherein the second section (8) is configured to be releasable positioned into the sleeve (5), in particular into the support sleeve (17), and comprises an opening (9) to receive a proximal portion of an elongated member (10) and wherein the plug device (6) comprises at least one fastening member (11) configured to establish a press fit and/or a twist and/or a clamp connection between the sleeve (5), in particular between the support sleeve (17), and the plug device (6), such that when the plug device (6) engages the sleeve (5), in particular the support sleeve (17), the cannula (1) is transferred from the normal to the low-profile configuration.
Support sleeve, for use in a cannula (1), in particular for medical applications, to form a proximal cannula portion (3), wherein the cannula (1) comprises a plurality of flexible filaments (4), such that the cannula (1) can be varied between a normal and a low-profile configuration, wherein the support sleeve (17) comprises a, in particular external, thread (13) and/or a protrusion (12) and/or a slot (15) configured to establish a press fit and/or a twist and/or a clamp connection between the cannula (1) and a plug device (6).
Cannula, in particular for use in medical applications, with a distal cannula portion (2) and a proximal cannula portion (3), wherein the cannula (1) comprises a plurality of flexible filaments (4), such that the cannula (1) can be varied between a normal and a low-profile configuration, wherein the proximal cannula portion (3) is formed by a sleeve (5), in particular by a support sleeve (17), wherein the sleeve (5), in particular the support sleeve (17), comprises a, in particular external, thread (13) and/or a protrusion (12) and/or a slot (15) configured to establish a press fit and/or a twist and/or a clamp connection between the sleeve (5), in particular between the support sleeve (17), and a plug device (6).
Kit of parts comprising,
- a cannula (1), in particular for use in medical applications, with a distal cannula portion (2) and a proximal cannula portion (3), wherein the cannula (1) comprises a plurality of flexible filaments (4), such that the cannula (1) can be varied between a normal and a low-profile configuration, wherein the proximal cannula portion (3) is formed by a sleeve (5), in particular by a support sleeve (17), and
- a plug device (6) comprising a first (7) and a second (8) section, wherein the second section (8) is configured to be releasable positioned into the sleeve (5), in particular into the support sleeve (17), and the second section comprises an opening (9) to receive a proximal portion of an elongated member (10) and wherein the plug device (6) comprises at least one fastening member (11) configured to establish a press fit and/or a twist and/or a clamp connection between the sleeve (5), in particular the support sleeve (17), and the plug device (6), such that when the plug device (6) engages the sleeve (5), in particular the support sleeve (17), the cannula (1) is transferred from the normal to the low-profile configuration.
