Abstract
An apparatus is disclosed for an optimized transseptal procedure that reduces the number of devices that are used in order to minimize procedural time, complexity and cost. The apparatus comprises a hybrid dilator that comprises the combined functionality of a transseptal sheath and dilator assembly. The hybrid dilator comprises: a dilator shaft defining a lumen for receiving a crossing device therethrough, a distal tip having an outer diameter which tapers down to an outer diameter of the crossing device for providing a smooth transition and a hub coupled with a side arm coupled to the dilator shaft.
Claims20
A hybrid dilator for use with a crossing device in tissue puncturing procedures, the hybrid dilator comprising:
- a dilator shaft extending between a proximal end and a distal end, the dilator shaft having a lumen for receiving a crossing device therethrough;
- a distal tip associated with the distal end, the distal tip having an outer diameter which tapers to an outer diameter of the crossing device for providing a smooth transition between the crossing device and the distal tip when the crossing device is inserted through the lumen and protrudes beyond the distal tip;
- and
- a hub coupled to the dilator shaft defining a lumen therethrough wherein the hub has a side arm.
A kit for puncturing a tissue comprising:
- a crossing device having a puncturing feature;
- and
- a hybrid dilator having:
- a dilator shaft extending between a proximal end and a distal end, the dilator shaft having a lumen for receiving a crossing device therethrough;
- a distal tip associated with the distal end, the distal tip having an outer diameter which tapers to an outer diameter of the crossing device for providing a smooth transition between the crossing device and the distal tip when the crossing device is inserted through the lumen and protrudes beyond the distal tip;
- and
- a hub coupled to the dilator shaft defining a lumen therethrough wherein the hub has a side arm.
A system for puncturing a tissue comprising:
- a crossing device having a puncturing feature which is operable to deliver energy to a tissue;
- an electrosurgical generator which is operable to provide energy to the puncturing feature;
- and
- a hybrid dilator having:
- a dilator shaft extending between a proximal end and a distal end, the dilator shaft having a lumen for receiving a crossing device therethrough;
- a distal tip associated with the distal end, the distal tip having an outer diameter which tapers to an outer diameter of the crossing device for providing a smooth transition between the crossing device and the distal tip when the crossing device is inserted through the lumen and protrudes beyond the distal tip;
- and
- a hub coupled to the dilator shaft defining a lumen therethrough wherein the hub has a side arm.
