Abstract
An apparatus includes a cylindrical shaft and an outwardly flared feature. The cylindrical shaft is sized for insertion into an insertion port of a cardiovascular catheter guiding sheath. The cylindrical shaft includes a proximal end, a distal end, and a lumen extending from the proximal end to the distal end. The lumen is sized to receive an end effector and catheter of a cardiovascular catheter instrument. The outwardly flared feature is at the proximal end of the cylindrical shaft. The outwardly flared feature defines an angled surface leading into the lumen.
Claims17
An apparatus, comprising:
- (a) a cylindrical shaft, the cylindrical shaft being sized for insertion into an insertion port of a cardiovascular catheter guiding sheath, the cylindrical shaft including:
- (i) a proximal end,
- (ii) a distal end,
- (iii) a lumen extending from the proximal end to the distal end, the lumen being sized to receive an end effector and a catheter of a cardiovascular catheter instrument, and
- (iv) a deformable seal member secured within the lumen, the deformable seal member comprising a material having a lower durometer than a durometer of the cylindrical shaft, the deformable seal member configured to deform against an outer surface of the end effector or catheter when the end effector and catheter are inserted through the cylindrical shaft to thereby form a fluid tight seal against the end effector or catheter while also allowing the catheter to translate through the lumen of the cylindrical shaft, the deformable seal member comprising one or more coupling portions that extend into one or more openings through a sidewall of the cylindrical shaft such that the one or more coupling portions comprise an exposed outer surface;
- and
- (b) an outwardly flared feature at the proximal end of the cylindrical shaft, the outwardly flared feature defining an angled surface leading into the lumen.
4 more elements
A kit, comprising:
- (a) a catheter instrument including:
- (i) a catheter having a distal end, and
- (ii) an end effector at the distal end of the catheter, the catheter and the end effector being sized to fit in a cardiovascular anatomical structure, the end effector including at least one electrode;
- and
- (b) an insert member including:
- (i) a cylindrical shaft including:
- (A) a proximal end,
- (B) a distal end,
- (C) a lumen extending from the proximal end of the cylindrical shaft to the distal end of the cylindrical shaft, the lumen being sized to receive the end effector and the catheter, and
- (D) a deformable seal member secured within the lumen, the deformable seal member comprising a material having a lower durometer material than a durometer of the cylindrical shaft, the deformable seal configured to deform against an outer surface of the catheter instrument when the catheter instrument is inserted through the cylindrical shaft to thereby form a fluid tight seal against the catheter instrument while also allowing the catheter instrument to translate through the lumen of the cylindrical shaft, the deformable seal member comprising one or more coupling portions that extend into one or more openings through a sidewall of the cylindrical shaft such that the one or more coupling portions comprise an exposed outer surface;
- and
- (ii) an outwardly flared feature at the proximal end of the cylindrical shaft, the outwardly flared feature defining an angled surface leading into the lumen.
9 more elements
A method comprising:
- positioning an insert member on a catheter, the insert member including:
- (i) a cylindrical shaft including:
- (A) a proximal end,
- (B) a distal end,
- (C) a lumen extending from the proximal end to the distal end, the lumen receiving the catheter, and
- (D) a deformable seal member secured within the lumen, the deformable seal member comprising a material having a lower durometer than a durometer of the cylindrical shaft, the deformable seal member configured to deform against an outer surface of the catheter when the catheter is inserted through the cylindrical shaft to thereby form a fluid tight seal against the catheter while also allowing the catheter to translate through the lumen of the cylindrical shaft, the deformable seal member comprising one or more coupling portions that extend into one or more openings through a sidewall of the cylindrical shaft such that the one or more coupling portions comprise an exposed outer surface;
- and
- (ii) an outwardly flared feature at the proximal end of the cylindrical shaft, the outwardly flared feature defining an angled surface leading into the lumen;
- the catheter being sized for insertion into a cardiovascular anatomical structure.
