Apparatus and method for manipulating or retracting tissue and anatomical structure
View Patent ↗Integrated systems and associated method for manipulating tissues and anatomical or other structures in medical applications for the purpose of treating diseases or disorders or other purposes. In one aspect, the system includes a delivery device configured to deploy and implant anchoring devices for such purposes.
1. A system for treatment of tissue at an interventional site, comprising:
a deployment device comprising an elongate member having a longitudinal axis; and
at least one retaining assembly including a first anchoring member, a second anchoring member, and a connector;
wherein the deployment device is configured to deliver the first anchoring member to tissue in a direction transverse to the longitudinal axis of the elongate member and wherein the deployment device is configured to fixedly join the first anchoring member to the second anchoring member via a pusher assembly configured to crimp the connector within the second anchoring member, thereby preventing axial movement of the connector with respect to the second anchoring member.
2. The system of claim 1 wherein the deployment device further comprises a needle.
3. The system of claim 2 wherein the first anchoring member is carried by the needle.
4. The system of claim 3 wherein the first anchoring member is carried within the needle.
5. The system of claim 2 wherein the needle travels in a direction transverse to the longitudinal axis of the elongate member to deliver the first anchoring member to tissue.
6. The system of claim 2 wherein the connector is carried by the needle.
7. The system of claim 1 wherein the deployment device is configured to deliver the first anchoring member to tissue with the connector fixedly joined to the first anchoring member.
8. The system of claim 1 wherein the deployment device is configured to fixedly join the second anchoring member to the connector such that a length of connector joining the first anchoring member to the second anchoring member is variable.
9. The system of claim 8 wherein the length is selectable by a user of the system.
10. The system of claim 1 wherein the deployment device further comprises a cutter assembly.
11. The system of 10 wherein the cutting assembly is configured to cut the connector.
12. A system for retaining tissue adjacent to a body lumen, comprising:
a retainer comprising a first endpiece, a second endpiece, and a connector, the retainer characterized by a delivery configuration and a retaining configuration wherein the retaining configuration comprises the connector being crimped within the second endpiece and thereby being prevented from moving axially with respect to the second endpiece; and
a delivery device configured to position and assemble the retainer into the retaining configuration, wherein the delivery device is configured to penetrate tissue in a direction transverse to the longitudinal axis of the body lumen, and the delivery device comprises a sizing mechanism configured to assemble the retainer to a custom size, wherein the sizing mechanism comprises a pusher mechanism configured to assemble the retainer.
13. A system for treating prostate tissue adjacent a urethral lumen, comprising:
a delivery device comprising a needle, wherein the delivery device is configured to be positioned at an interventional site within the urethral lumen and wherein the needle is configured to penetrate prostate tissue in a direction transverse to the urethral lumen; and
a retainer comprising a first endpiece, a second endpiece, and a connector, wherein the retainer is configured to be carried into prostate tissue by the needle; and
an assembly mechanism configured to assemble the retainer by crimping at least one endpiece to the connector thereby preventing axial movement of the connector with respect to the one endpiece.
14. The system of claim 13 wherein the assembly mechanism is configured to fixedly attach the second endpiece to the connector.
