Introducer sheath and hub assembly
First Claim
1. A device, comprising:
- a tube member;
a treatment member, having a first diameter, disposed at least partly within the tube member and having a distal end configured to deliver energy in connection with performance of a medical procedure;
a hub member, comprising;
a securement portion configured to secure the hub member to the treatment member;
a seal positioned between the tube member and the securement portion; and
a delivery portion coupled to the tube member, wherein the securement portion and the delivery portion are configured to be removably coupled together; and
a sleeve member having a second diameter;
wherein the sleeve member is disposed about the treatment member;
wherein the second diameter is larger than the first diameter, such that as the treatment member is advanced through the seal, the sleeve member contacts the seal and provides resistance to further advancement of the treatment member, and wherein the securement portion and the delivery portion are spaced apart from each other at a pre-determined distance such that,contact between a distal end of the sleeve member and the seal correlates to disposition of the treatment member with respect to the delivery portion in an advancement position wherein the delivery member protects the treatment member from damage and/or from damaging body tissue anddisposition of the distal end of the sleeve distal of the seal correlates to disposition of the treatment member with respect to the delivery portion in a treatment position wherein the treatment member extends from the delivery member such that the treatment member may be used for treatment.

14. A device, comprising:
-
a treatment member; a hub member, including; a securement portion configured to secure the hub member to the treatment member; and a delivery portion, wherein the securement portion is directly coupled to the delivery portion; and a sleeve member coupled to the securement portion, wherein the sleeve member is configured to hold the securement portion and the delivery portion apart from each other at a pre-determined distance in a first arrangement wherein the treatment member is in an advancement position with respect to the delivery portion such that the delivery portion protects the treatment member from damage and/or from damaging body tissue, and configured to provide an indication of the relative position of the treatment member with respect to the delivery portion, and wherein the sleeve member is further configured to at least partially reside in the hub member in a second arrangement wherein the treatment member is in a treatment position with respect to the delivery portion such that the treatment member extends from the delivery portion such that the treatment member may be used for treatment. - View Dependent Claims (15, 16, 17)
